A Preliminary Report On The Vertebrate Paleontology Of The Llano Estacado,

Vertebrate PaleontologyThe vertebrate paleontology collection contains roughly eighty,000 cataloged specimens. ^ Hackett, S.J., Kimball, R.T., Reddy, S., Bowie, R.C.K., Braun, E.L., Braun, M.J., Chojnowski, J.L., Cox, W.A., Han, Okay-L., Harshman, J., Huddleston, C.J., Marks, B.D., Miglia, Ok.J., Moore, W.S., Sheldon, F.H., Steadman, D.W., Witt, C.C. and Yuri T. (2008) A phylogenomic study of birds reveals their evolutionary history.

Current paleontological analysis on the Academy of Natural Sciences is focused on Late Devonian-age fossils (375 to 365-million-years-old) from theĀ Catskill Formation in northern Pennsylvania and from theĀ Okse Bay Group in the Nunavut Territory of the Canadian Arctic.

The earliest known fossil vertebrates have been heavily armored fish discovered in rocks from the Ordovician Interval about 500 to 430 Ma. The Devonian Interval brought in the changes that allowed primitive air-breathing fish to stay on land so long as they wished, thus turning into the primary terrestrial vertebrates, the amphibians.

The 1998 transfer of the University of Cincinnati paleontology assortment (begun in 1907) to the Museum and an intensive program of research-oriented excavations has created the lower Ohio Valley’s largest vertebrate fossil assortment, numbering roughly 30,000 specimens (over eight,000 of which are at present catalogued on the Museum’s KeEMu database server).
