Prehistoric Trackways National Monument - Discovery

Discovery

In situ Paleozoic Era tracks were discovered on June 6, 1987 by Jerry Paul MacDonald. Scattered footprints had been found in the Robledo’s for almost fifty years prior to Jerry MacDonald starting his search. He used the recollections of local hikers, quarrymen, and fossil hunters to concentrate his search. This initial site was named the “Discovery Site”. It is one of the best places in the monument for visitors to see fossilized tracks. Jerry MacDonald excavated three long trackways, carrying over 2500 slabs out from the site on his back. The majority of the slabs are housed in the New Mexico Museum of Natural History and Science in the Jerry MacDonald Paleozoic Trackways Collection. Two other continuous trackways are held in the Carnegie Museum and Smithsonian.

Famous quotes containing the word discovery:

    He is not a true man of science who does not bring some sympathy to his studies, and expect to learn something by behavior as well as by application. It is childish to rest in the discovery of mere coincidences, or of partial and extraneous laws. The study of geometry is a petty and idle exercise of the mind, if it is applied to no larger system than the starry one.
    Henry David Thoreau (1817–1862)

    Your discovery of the contradiction caused me the greatest surprise and, I would almost say, consternation, since it has shaken the basis on which I intended to build my arithmetic.... It is all the more serious since, with the loss of my rule V, not only the foundations of my arithmetic, but also the sole possible foundations of arithmetic seem to vanish.
    Gottlob Frege (1848–1925)

    As the mother of a son, I do not accept that alienation from me is necessary for his discovery of himself. As a woman, I will not cooperate in demeaning womanly things so that he can be proud to be a man. I like to think the women in my son’s future are counting on me.
    Letty Cottin Pogrebin (20th century)
