#paleontologists — Public Fediverse posts

“A 10,000 year-old tooth in remarkable condition from an ancient Pacific mastodon, a large #mammal that once inhabited North America, was recently discovered by a California scientist.

#BrigidLynch, a #geomorphologist, was working at a preserve in San Mateo county, when she stumbled across a peculiar rock.”

#Paleontologists later confirmed it was not a stone, but an adult Pacific #mastodon molar, according to a Wednesday news release from the Midpeninsula regional open space district (Midpen).”

The #Megaraptor Had Giant Claws and an Appetite for Crocodilians
A #fossil of the 23-foot-tall #predator could help unlock secrets of an order of #dinosaurs that remain poorly understood.
As the team of #paleontologists worked on the remains, they realized that a bone tucked between the jaws was not from the #skeleton: it was, instead, the upper arm bone of a #crocodile relative. The dinosaur’s teeth were actually touching the crocodile bone.

#Paleontologists Discover New Species of Spinosaurid Dinosaur
https://www.sci.news/paleontology/protathlitis-cinctorrensis-11931.html

A new spinosaurid #dinosaur species from the Early #Cretaceous of Cinctorres (Spain) https://www.nature.com/articles/s41598-023-33418-2

The discovery of #Protathlitis cinctorrensis suggests that the #IberianPeninsula may have been a diverse area for medium-to-large bodied #spinosaurid #dinosaurs and sheds light on the origin and evolution of #spinosaurids.
