A rare ancient shark has been identified by New Mexico paleontologists


Dracopristis and other species of ctenacanths are part of a unique evolutionary branch of the sharks that diverged from modern sharks and rays roughly 390 million years ago and became extinct by the end of the Paleozoic Era some 252 million years ago.
The assembled team was led by paleontologist John-Paul Hodnett, the program coordinator for the Maryland-National Capital Parks and Planning Commission’s Dinosaur Park in Laurel, Maryland, and also included Eileen D. Grogan and Richard Lund of St. Joseph’s University in Pennsylvania; Spencer G. Lucas, Curator of Paleontology at NMMNHS; Tom Suazo, former fossil preparator at NMMNHS; David K. Elliot of Northern Arizona University; and Jesse Pruitt of Idaho State University.  ....

“Great for grasping and crushing prey rather than piercing prey,” said discoverer John-Paul Hodnett, who was a graduate student when he unearthed the first fossils of the shark at a dig east of Albuquerque in 2013.
This week, Hodnett and a slew of other researchers published their findings in a bulletin of the New Mexico Museum of Natural History & Science identifying the shark as a separate species. ....
