An ancient sink hole in eastern
Tennessee holds the clues to an important transitional time in the evolutionary
history of snakes. Among the fossilized creatures found there, according to a
new paper co-authored by a University of Pennsylvania paleontologist, is a new
species of snake that lived 5 million years ago.
Steven Jasinski, lead author of
the new study, is a doctoral student in Penn's Department of Earth and
Environmental Science in the School of Arts & Sciences and acting curator
of paleontology and geology at the State Museum of Pennsylvania. He is
completing his Ph.D. under Peter Dodson, a professor of paleontology in Arts
& Sciences and professor of anatomy in the School of Veterinary Medicine at
Penn.
The fossils come from the Gray
Fossil Site near East Tennessee State University, where Jasinski and co-author
David Moscato pursued their master's degrees.
