Staff, Research Associates, professional paleontologists, and graduate students frequent the collections throughout the year.
Today's research ranges from carbon dating projects to asphalt-dwelling microbial ecology to traditional taxonomic and functional studies. Many questions still remain to be answered. The collections are available for any appropriately qualified person interested in doing formal research. All inquiries must be made through the Collections Managerincluding requests for loans of specimens.
We only loan specimens to institutions. Are you a student who wishes to visit the Rancho La Brea collections for your research?
A Radiometric Dating Resource List
No other paleontological site in the world has as great a potential to answer these questions as the La Brea Tar Pits. I have conducted fieldwork in the United States, Antarctica, Chile, Guyana, and Ecuador, where my ongoing research program focuses on investigating the rich asphaltic fossil localities of the Santa Elena Peninsula and comparing them with our own tar pits here in California.
Libby Ellwood Postdoctoral Research Fellow My ecological research occurs at the intersection of climate change, conservation, and citizen science. I work to understand past systems while conducting contemporary research to see how these systems have changed and how they may continue to change in the future. This research depends on historical or ancient information and citizen scientists are playing an increasing role in making such data available.
Recently, I completed a postdoctoral position with iDigBio at Florida State University where I worked to engage the public in digitizing specimens and data contained in natural history collections.
Specifically, I'm developing educational resources to involve students in sorting microfossils that will inform us of the small mammals and plants that comprised ecosystems hereyears ago. I apply a diverse methodological toolkit to understand how faunal communities have changed over the past 20, years into today, and place these results in a modern conservation context.
At La Brea, I use stable isotopes of Holocene fauna to develop a baseline for understanding the rapidly changing biodiversity of Los Angeles. I am excited to compare the Holocene of California with my ongoing research of Caribbean mammal extinctions - especially all things insectivore! One is the detailed description of the bones of teratorns and the identification of distinguishing characteristics of the two genera and species that occur in the tar pit collections. The second is a complete reevaluation of the nine species of fossil owls in the collections, which is undertaken in collaboration with Dr.
Zbigniew Bochenski of Poland. The study of the owls will result in the description of new genera and species. A recently completed study was a revision and re-description of the extinct California Turkey, Meleagris californica, coauthored with Dr. Other families of birds are also being prepared for detailed revisionary studies.
Assessing millennial-scale community dynamics using mammal and vegetation food webs Dr. Justin Yeakel, Assistant Professor, Life and Environmental Sciences, UC Merced We are working on an NSF-funded project to build multi-trophic food webs for La Brea paleo-ecosystems and reconstruct changes in the composition and structure of the ecological network in California across the late 50, years.
We will then examine the stability of food webs to external perturbations, both simulated e. This will give us an idea of how resilient different species were to climate and human impacts and whether properties of the overall interaction networks predict the vulnerability of individual species.
John Southon at UC Irvine. My research focuses mainly on carnivore functional morphology. To date we have focused on using 3D dental microwear to evaluate the degree of hard object feeding in cats and bears. Fuller Department of Archaeology and Heritage Studies, Aarhus University, Denmark Our recent research is focused on the development of methods for asphalt removal from bone collagen for radiocarbon dating and stable isotope ratio analysis of Pleistocene fauna at Rancho La Brea.
Directly linking radiocarbon ages with isotopic results permits the reconstruction of diet and ecology of the species and will help determine if they were influenced by changing climatic conditions over the past 50, years. I celebrate myself, and sing myself, And what I assume you shall assume, For every atom belonging to me as good belongs to you. I loafe and invite my soul, I lean and loafe at my ease observing a spear of summer grass. My tongue, every atom of my blood, form'd from this soil, this air, Born here of parents born here from parents the same, and their parents the same, I, now thirty-seven years old in perfect health begin, Hoping to cease not till death.
Creeds and schools in abeyance, Retiring back a while sufficed at what they are, but never forgotten, I harbor for good or bad, I permit to speak at every hazard, Nature without check with original energy. The atmosphere is not a perfume, it has no taste of the distillation, it is odorless, It is for my mouth forever, I am in love with it, I will go to the bank by the wood and become undisguised and naked, I am mad for it to be in contact with me.
The smoke of my own breath, Echoes, ripples, buzz'd whispers, love-root, silk-thread, crotch and vine, My respiration and inspiration, the beating of my heart, the passing of blood and air through my lungs, The sniff of green leaves and dry leaves, and of the shore and dark-color'd sea-rocks, and of hay in the barn, The sound of the belch'd words of my voice loos'd to the eddies of the wind, A few light kisses, a few embraces, a reaching around of arms, The play of shine and shade on the trees as the supple boughs wag, The delight alone or in the rush of the streets, or along the fields and hill-sides, The feeling of health, the full-noon trill, the song of me rising from bed and meeting the sun.
Have you reckon'd a thousand acres much? Have you practis'd so long to learn to read?
Have you felt so proud to get at the meaning of poems? Stop this day and night with me and you shall possess the origin of all poems, You shall possess the good of the earth and sun, there are millions of suns left, You shall no longer take things at second or third hand, nor look through the eyes of the dead, nor feed on the spectres in books, You shall not look through my eyes either, nor take things from me, You shall listen to all sides and filter them from your self.
There was never any more inception than there is now, Nor any more youth or age than there is now, And will never be any more perfection than there is now, Nor any more heaven or hell than there is now.
Urge and urge and urge, Always the procreant urge of the world.
Out of the dimness opposite equals advance, always substance and increase, always sex, Always a knit of identity, always distinction, always a breed of life. To elaborate is no avail, learn'd and unlearn'd feel that it is so. Sure as the most certain sure, plumb in the uprights, well entretied, braced in the beams, Stout as a horse, affectionate, haughty, electrical, I and this mystery here we stand.
Clear and sweet is my soul, and clear and sweet is all that is not my soul. Lack one lacks both, and the unseen is proved by the seen, Till that becomes unseen and receives proof in its turn. Showing the best and dividing it from the worst age vexes age, Knowing the perfect fitness and equanimity of things, while they discuss I am silent, and go bathe and admire myself.
Welcome is every organ and attribute of me, and of any man hearty and clean, Not an inch nor a particle of an inch is vile, and none shall be less familiar than the rest.

I am satisfied--I see, dance, laugh, sing; As the hugging and loving bed-fellow sleeps at my side through the night, and withdraws at the peep of the day with stealthy tread, Leaving me baskets cover'd with white towels swelling the house with their plenty, Shall I postpone my acceptation and realization and scream at my eyes, That they turn from gazing after and down the road, And forthwith cipher and show me to a cent, Exactly the value of one and exactly the value of two, and which is ahead?
Apart from the pulling and hauling stands what I am, Stands amused, complacent, compassionating, idle, unitary, Looks down, is erect, or bends an arm on an impalpable certain rest, Looking with side-curved head curious what will come next, Both in and out of the game and watching and wondering at it. Backward I see in my own days where I sweated through fog with linguists and contenders, I have no mockings or arguments, I witness and wait. Loafe with me on the grass, loose the stop from your throat, Not words, not music or rhyme I want, not custom or lecture, not even the best, Only the lull I like, the hum of your valved voice.
I mind how once we lay such a transparent summer morning, How you settled your head athwart my hips and gently turn'd over upon me, And parted the shirt from my bosom-bone, and plunged your tongue to my bare-stript heart, And reach'd till you felt my beard, and reach'd till you held my feet.
Swiftly arose and spread around me the peace and knowledge that pass all the argument of the earth, And I know that the hand of God is the promise of my own, And I know that the spirit of God is the brother of my own, And that all the men ever born are also my brothers, and the women my sisters and lovers, And that a kelson of the creation is love, And limitless are leaves stiff or drooping in the fields, And brown ants in the little wells beneath them, And mossy scabs of the worm fence, heap'd stones, elder, mullein and poke-weed.
I do not know what it is any more than he. I guess it must be the flag of my disposition, out of hopeful green stuff woven. Or I guess it is the handkerchief of the Lord, A scented gift and remembrancer designedly dropt, Bearing the owner's name someway in the corners, that we may see and remark, and say Whose?
Or I guess the grass is itself a child, the produced babe of the vegetation. Or I guess it is a uniform hieroglyphic, And it means, Sprouting alike in broad zones and narrow zones, Growing among black folks as among white, Kanuck, Tuckahoe, Congressman, Cuff, I give them the same, I receive them the same. And now it seems to me the beautiful uncut hair of graves.
Tenderly will I use you curling grass, It may be you transpire from the breasts of young men, It may be if I had known them I would have loved them, It may be you are from old people, or from offspring taken soon out of their mothers' laps, And here you are the mothers' laps. This grass is very dark to be from the white heads of old mothers, Darker than the colorless beards of old men, Dark to come from under the faint red roofs of mouths.
O I perceive after all so many uttering tongues, And I perceive they do not come from the roofs of mouths for nothing. I wish I could translate the hints about the dead young men and women, And the hints about old men and mothers, and the offspring taken soon out of their laps.
What do you think has become of the young and old men? And what do you think has become of the women and children? They are alive and well somewhere, The smallest sprout shows there is really no death, And if ever there was it led forward life, and does not wait at the end to arrest it, And ceas'd the moment life appear'd. All goes onward and outward, nothing collapses, And to die is different from what any one supposed, and luckier.
I hasten to inform him or her it is just as lucky to die, and I know it. I pass death with the dying and birth with the new-wash'd babe, and am not contain'd between my hat and boots, And peruse manifold objects, no two alike and every one good, The earth good and the stars good, and their adjuncts all good.
I am not an earth nor an adjunct of an earth, I am the mate and companion of people, all just as immortal and fathomless as myself, They do not know how immortal, but I know. Every kind for itself and its own, for me mine male and female, For me those that have been boys and that love women, For me the man that is proud and feels how it stings to be slighted, For me the sweet-heart and the old maid, for me mothers and the mothers of mothers, For me lips that have smiled, eyes that have shed tears, For me children and the begetters of children.
The youngster and the red-faced girl turn aside up the bushy hill, I peeringly view them from the top.
The suicide sprawls on the bloody floor of the bedroom, I witness the corpse with its dabbled hair, I note where the pistol has fallen. I am there, I help, I came stretch'd atop of the load, I felt its soft jolts, one leg reclined on the other, I jump from the cross-beams and seize the clover and timothy, And roll head over heels and tangle my hair full of wisps.
The Yankee clipper is under her sky-sails, she cuts the sparkle and scud, My eyes settle the land, I bend at her prow or shout joyously from the deck. The boatmen and clam-diggers arose early and stopt for me, I tuck'd my trowser-ends in my boots and went and had a good time; You should have been with us that day round the chowder-kettle.

I saw the marriage of the trapper in the open air in the far west, the bride was a red girl, Her father and his friends sat near cross-legged and dumbly smoking, they had moccasins to their feet and large thick blankets hanging from their shoulders, On a bank lounged the trapper, he was drest mostly in skins, his luxuriant beard and curls protected his neck, he held his bride by the hand, She had long eyelashes, her head was bare, her coarse straight locks descended upon her voluptuous limbs and reach'd to her feet.
The runaway slave came to my house and stopt outside, I heard his motions crackling the twigs of the woodpile, Through the swung half-door of the kitchen I saw him limpsy and weak, And went where he sat on a log and led him in and assured him, And brought water and fill'd a tub for his sweated body and bruis'd feet, And gave him a room that enter'd from my own, and gave him some coarse clean clothes, And remember perfectly well his revolving eyes and his awkwardness, And remember putting piasters on the galls of his neck and ankles; He staid with me a week before he was recuperated and pass'd north, I had him sit next me at table, my fire-lock lean'd in the corner.
She owns the fine house by the rise of the bank, She hides handsome and richly drest aft the blinds of the window. Which of the young men does she like the best? Ah the homeliest of them is beautiful to her.
Where are you off to, lady? Dancing and laughing along the beach came the twenty-ninth bather, The rest did not see her, but she saw them and loved them. The beards of the young men glisten'd with wet, it ran from their long hair, Little streams pass'd all over their bodies. An unseen hand also pass'd over their bodies, It descended tremblingly from their temples and ribs.
The young men float on their backs, their white bellies bulge to the sun, they do not ask who seizes fast to them, They do not know who puffs and declines with pendant and bending arch, They do not think whom they souse with spray. Blacksmiths with grimed and hairy chests environ the anvil, Each has his main-sledge, they are all out, there is a great heat in the fire.
From the cinder-strew'd threshold I follow their movements, The lithe sheer of their waists plays even with their massive arms, Overhand the hammers swing, overhand so slow, overhand so sure, They do not hasten, each man hits in his place. I behold the picturesque giant and love him, and I do not stop there, I go with the team also. In me the caresser of life wherever moving, backward as well as forward sluing, To niches aside and junior bending, not a person or object missing, Absorbing all to myself and for this song.
Oxen that rattle the yoke and chain or halt in the leafy shade, what is that you express in your eyes? It seems to me more than all the print I have read in my life. My tread scares the wood-drake and wood-duck on my distant and day-long ramble, They rise together, they slowly circle around. I believe in those wing'd purposes, And acknowledge red, yellow, white, playing within me, And consider green and violet and the tufted crown intentional, And do not call the tortoise unworthy because she is not something else, And the in the woods never studied the gamut, yet trills pretty well to me, And the look of the bay mare shames silliness out of me.
The sharp-hoof'd moose of the north, the cat on the house-sill, the chickadee, the prairie-dog, The litter of the grunting sow as they tug at her teats, The brood of the turkey-hen and she with her half-spread wings, I see in them and myself the same old law.
The press of my foot to the earth springs a hundred affections, They scorn the best I can do to relate them. I am enamour'd of growing out-doors, Of men that live among cattle or taste of the ocean or woods, Of the builders and steerers of ships and the wielders of axes and mauls, and the drivers of horses, I can eat and sleep with them week in and week out. What is commonest, cheapest, nearest, easiest, is Me, Me going in for my chances, spending for vast returns, Adorning myself to bestow myself on the first that will take me, Not asking the sky to come down to my good will, Scattering it freely forever.
The drover watching his drove sings out to them that would stray, The pedler sweats with his pack on his back, the purchaser higgling about the odd cent; The bride unrumples her white dress, the minute-hand of the clock moves slowly, The opium-eater reclines with rigid head and just-open'd lips, The prostitute draggles her shawl, her bonnet bobs on her tipsy and pimpled neck, The crowd laugh at her blackguard oaths, the men jeer and wink to each other, Miserable!
I do not laugh at your oaths nor jeer you; The President holding a cabinet council is surrounded by the great Secretaries, On the piazza walk three matrons stately and friendly with twined arms, The crew of the fish-smack pack repeated layers of halibut in the hold, The Missourian crosses the plains toting his wares and his cattle, As the fare-collector goes through the train he gives notice by the jingling of loose change, The floor-men are laying the floor, the tinners are tinning the roof, the masons are calling for mortar, In single file each shouldering his hod pass onward the laborers; Seasons pursuing each other the indescribable crowd is gather'd, it is the fourth of Seventh-month, what salutes of cannon and small arms!

I resist any thing better than my own diversity, Breathe the air but leave plenty after me, And am not stuck up, and am in my place. The moth and the fish-eggs are in their place, The bright suns I see and the dark suns I cannot see are in their place, The palpable is in its place and the impalpable is in its place. This is the grass that grows wherever the land is and the water is, This the common air that bathes the globe.
Have you heard that it was good to gain the day? I also say it is good to fall, battles are lost in the same spirit in which they are won.
I beat and pound for the dead, I blow through my embouchures my loudest and gayest for them. Vivas to those who have fail'd! And to those whose war-vessels sank in the sea! And to those themselves who sank in the sea! And to all generals that lost engagements, and all overcome heroes!
And the numberless unknown heroes equal to the greatest heroes known! This is the press of a bashful hand, this the float and odor of hair, This the touch of my lips to yours, this the murmur of yearning, This the far-off depth and height reflecting my own face, This the thoughtful merge of myself, and the outlet again.
Do you guess I have some intricate purpose? Well I have, for the Fourth-month showers have, and the mica on the side of a rock has. Do you take it I would astonish? Does the daylight astonish? Do I astonish more than they? This hour I tell things in confidence, I might not tell everybody, but I will tell you. What is a man anyhow? All I mark as my own you shall offset it with your own, Else it were time lost listening to me. I do not snivel that snivel the world over, That months are vacuums and the ground but wallow and filth.
Whimpering and truckling fold with powders for invalids, conformity goes to the fourth-remov'd, I wear my hat as I please indoors or out. Why should I pray? Having pried through the strata, analyzed to a hair, counsel'd with doctors and calculated close, I find no sweeter fat than sticks to my own bones. In all people I see myself, none more and not one a barley-corn less, And the good or bad I say of myself I say of them. I know I am solid and sound, To me the converging objects of the universe perpetually flow, All are written to me, and I must get what the writing means.
I know I am deathless, I know this orbit of mine cannot be swept by a carpenter's compass, I know I shall not pass like a child's carlacue cut with a burnt stick at night. I know I am august, I do not trouble my spirit to vindicate itself or be understood, I see that the elementary laws never apologize, I reckon I behave no prouder than the level I plant my house by, after all. I exist as I am, that is enough, If no other in the world be aware I sit content, And if each and all be aware I sit content.
One world is aware and by far the largest to me, and that is myself, And whether I come to my own to-day or in ten thousand or ten million years, I can cheerfully take it now, or with equal cheerfulness I can wait. My foothold is tenon'd and mortis'd in granite, I laugh at what you call dissolution, And I know the amplitude of time. I am the poet of the woman the same as the man, And I say it is as great to be a woman as to be a man, And I say there is nothing greater than the mother of men.
I chant the chant of dilation or pride, We have had ducking and deprecating about enough, I show that size is only development. Have you outstript the rest? It is a trifle, they will more than arrive there every one, and still pass on.
I am he that walks with the tender and growing night, I call to the earth and sea half-held by the night. Press close bare-bosom'd night--press close magnetic nourishing night! Night of south winds--night of the large few stars! Still nodding night--mad naked summer night. Smile O voluptuous cool-breath'd earth! Earth of the slumbering and liquid trees! Earth of departed sunset--earth of the mountains misty-topt! Earth of the vitreous pour of the full moon just tinged with blue!
Earth of shine and dark mottling the tide of the river! Earth of the limpid gray of clouds brighter and clearer for my sake!
Far-swooping elbow'd earth--rich apple-blossom'd earth! Smile, for your lover comes. Prodigal, you have given me love--therefore I to you give love! O unspeakable passionate love. I resign myself to you also--I guess what you mean, I behold from the beach your crooked fingers, I believe you refuse to go back without feeling of me, We must have a turn together, I undress, hurry me out of sight of the land, Cushion me soft, rock me in billowy drowse, Dash me with amorous wet, I can repay you.
Sea of stretch'd ground-swells, Sea breathing broad and convulsive breaths, Sea of the brine of life and of unshovell'd yet always-ready graves, Howler and scooper of storms, capricious and dainty sea, I am integral with you, I too am of one phase and of all phases. Partaker of influx and efflux I, extoller of hate and conciliation, Extoller of amies and those that sleep in each others' arms.
I am he attesting sympathy, Shall I make my list of things in the house and skip the house that supports them? I am not the poet of goodness only, I do not decline to be the poet of wickedness also.
