Tooth Serves as Evidence of 220 Million-Year-old Attack

Reconstruction of the interaction of large land predators (rauisuchid) and aquatic predator (phytosaur) about 210 million years ago based on research by a joint team of University of Tennessee and Virginia Tech researchers. Christopher Hayes, a freshman at Virginia Tech, composed the drawing.

At the beginning of the age of dinosaurs, gigantic reptiles—distant relatives of modern crocodiles—ruled the earth. Some lived on land and others in water and it was thought they didn’t much interact. But a tooth found by a UT researcher in the thigh of one of these ancient animals is challenging this belief.

Lecturer to Discuss Crocodylian Bite Marks at Friday’s Science Forum

Stephanie Drumheller-Horton, lecturer in the Department of Earth and Planetary Sciences, helped make an interesting discovery in a dinosaur fossil earlier this year. She will be discussing her research at the Science Forum at noon on Friday, April 12, in Dining Room C-D of Thompson-Boling Arena.

UT Expert Helps Find Evidence That Prehistoric Crocs Ate Small Dinosaurs

Drumheller-Horton feeding a partial cow hind limb to a group of American alligators at the St. Augustine Alligator Farm in Florida. She was collecting bite mark samples from different species of crocodylian on cow and pig limbs.

Prehistoric relatives to crocodiles and alligators fed on tiny dinosaurs, according to fossil evidence discovered by a team of researchers, including a UT lecturer. Stephanie Drumheller, a 2005 graduate and lecturer in the Department of Earth and Planetary Sciences, analyzed bite marks on some seventy-five-million-year-old dinosaur bones that were collected in southern Utah in 2002.
