Tellus Museum Installs 31-Foot Deinosuchus Replica Based on 40 Years of Research

Q: What terrifying secrets do the 3D-scanned dermal armor and fossilized bite marks reveal about this giant predator's hunting strategies?

The evidence points to a heavily armored, water-edge ambush predator that could seize and crush exceptionally large prey, including dinosaurs and hard-shelled turtles. The 3D-scanned dermal armor, or osteoderms, shows Deinosuchus schwimmeri was not just big but built like a tank. Those thick, deeply pitted bony plates likely protected it during violent struggles and helped anchor strong body muscles, especially along the back and torso. That matters because an animal this size needed power and stability to lunge from shallow water, clamp down on prey, and control it once captured. Fossilized bite marks provide the clearer behavioral clue. Marks on dinosaur bones indicate Deinosuchus bit into large terrestrial animals at the water’s edge, consistent with the hunting style of modern crocodilians: waiting in rivers, estuaries, or swamps and attacking suddenly when prey approached. Researchers cannot always prove whether every marked dinosaur was killed or scavenged, but the damage shows it was fully capable of tackling very large animals. Other evidence, including coprolites and bitten turtle shells, suggests it was also a bone-crushing generalist feeder. Its broad jaws and robust teeth were suited not only for gripping prey but for cracking shell and bone. Taken together, the armor scans and feeding traces reveal a predator that relied on concealment, explosive short-range attacks, immense bite force, and the ability to overpower prey in or near water.

A 31-foot mounted skeleton of Deinosuchus schwimmeri has been installed at Georgia’s Tellus Science Museum as the first scientifically accurate life-size replica of the giant crocodilian.
Two years of work between paleontologist David Schwimmer and Triebold Paleontology used high-resolution fossil scans to reconstruct the animal’s skeleton and armored skin plates from fragmentary remains.
The species, formally identified in 2020 and named for Schwimmer, lived about 83 million to 76 million years ago and was large enough to attack dinosaurs near waterways in the eastern United States.
Tellus said it is the only museum with a cast of Deinosuchus schwimmeri, giving students and visitors a rare view of a predator that once dominated the broader Southeast.
The display also extends Schwimmer’s four decades of fieldwork in Georgia and nearby states, turning regional fossil discoveries into a research and education tool.
