Book Description
Excerpt from Revision of the Pelycosauria of North America The vertebrate fauna of the Permian beds of North America was made known as early as 1877-78, and quickly attracted the attention of Professor Cope, who, with his wonderful acumen, saw the importance of the fauna lying so close to the beginnings of the reptilian line. From the first discovery of Permian reptiles until his death he retained his interest in the group, some of his latest papers having to do with the orders Cotylosanria and Chelydosauria. Much of the material in the collections of Professor Cope is in a very fragmentary condition, and none of it was carefully prepared while in his possession. He contented himself with the description of new forms without detailed study or complete morphological discussion, and yet he based upon this material many of his most brilliant generalizations; and it is more surprising that he should have seen so much and built so well than that he described some genera and species that will not stand and drew some conclusions that have proven incorrect. From the discovery of Permian vertebrates in Texas until his death. Cope sent parties into the field at irregular intervals, and the material collected by them is now preserved in the American Museum of Natural History in New York. These collections contain the types from Texas described by Cope. A small collection made in Vermilion county, Illinois, by Mr. William Gurley, and now in the Walker Museum of the University of Chicago, contains the types from Illinois described by Cope. Another small collection obtained from New Mexico by Professor Marsh is preserved in the Museum of Yale University. The author made two collections in Texas for the University of Chicago in 1895 and 1903;these are preserved in the Walker Museum and contain the specimens upon which was based the work of the late Doctor Baur and the author.
