Bitten Bones Show Alligators are Rough Feeders


National Geographic featured the research of Stephanie Drumheller, an earth and planetary sciences lecturer. Drumheller’s work involved giving alligators n pig bones or cow legs. Through understanding the damage modern alligators leave on bones, Drumheller and other paleontologists can follow the depredations of alligators and their crocodile cousins through time. “In order to see the

Triassic Bites and a Carnivore Conundrum


National Geographic featured an in-depth story on the research of Stephanie Drumheller, an earth and planetary sciences lecturer. She and her Virginia Tech colleagues examined 220-million-year-old bite marks in the thigh bones of an old reptile and found evidence that two predators at the top of their respective food chains interacted—with the smaller potentially having

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.
