Episode 22: Matheronodon, a new dinosaur with a different kind of bite! Dec 08, 2017

Show notes

Matheronodon is certainly a dinosaur worthy of a bigger bite. With proportionally giant teeth strikingly different from the standard-issue ornithopod dinosaur, it is certainly one of the most important dino discoveries out of Europe this year. Better yet, the original scientific paper by Pascal Godefroit and colleagues is free to read in the journal Scientific […]

A Food Chain in a Fossil: A snake skeleton with its prey still inside! Aug 31, 2016

Show notes

The relationship between predator and prey is a primal one, and one that fires the curiosity of many fossil fans. We love paintings of Tyrannosaurus battling Triceratops or saber-toothed cats leaping onto the backs of ground sloths. And we can be pretty sure that those interactions happened based on TRACE FOSSILS, like tooth marks in […]

Grandma Sharkie: The Greenland Shark is the World’s Oldest Vertebrate Animal! Aug 15, 2016
