A new type of horned dinosaur, whose 82-million-year-old fossilized remains were found near Cuba in 1993, is believed to be the oldest representative of all the horned dinosaurs that have yet been discovered, said Spencer Lucas, curator of paleontology at the New Mexico Museum of Natural History and Science.

Newly described horned dinosaur from New Mexico was the earliest of its kind


.
Menefeeceratops sealeyi adds important information to scientists’ understanding of the evolution of ceratopsid dinosaurs, which are characterized by horns and frills, along with beaked faces. In particular, the discovery sheds light on the centrosaurine subfamily of horned dinosaurs, of which
Menefeeceratops is believed to be the oldest member. Its remains offer a clearer picture of the group’s evolutionary path before it went extinct at the end of the Cretaceous.
Steven Jasinski, who recently completed his Ph.D. in Penn’s Department of Earth and Environmental Science in the School of Arts & Sciences, and Peter Dodson of the School of Veterinary Medicine and Penn Arts & Sciences, collaborated on the work, which was led by Sebastian Dalman of the New Mexico Museum of Natural History and Science. Spencer Lucas and Asher Lichtig of the New Mexico Museum of Natural History and Science in Albuquerque were also part of the research team. ....

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.  ....
