A damaged dinosaur skull that was once thought to be nearly worthless has led to the discovery of a new carnivorous species. This creature lived over 230 million years ago, much earlier than the Tyrannosaurus rex. This find has reshaped our understanding of early dinosaur evolution, according to new research published in Papers in Palaeontology.
A Surprising Find
In a Virginia Tech lab, researchers discovered that this badly deformed skull, long overlooked because of its condition, contained vital clues about a previously unknown species. Geosciences student Simba Srivastava found potential where others saw a disaster. “You want to stick your finger in a dinosaur brain?” he playfully asked. His curiosity led to a two-year investigation. He remarked, “This is a uniquely sucky specimen—it’s so bad, you’d throw up if you found a human skull like this.”
Despite its poor condition, advanced CT scanning and 3D reconstruction revealed a wealth of information. This process turned a seemingly useless fossil into the only known example of a new species.
A Student’s Innovation
Typically, fossil analysis is conducted by seasoned researchers. However, Srivastava was encouraged to take charge of this project from start to finish. Dr. Sterling Nesbitt, one of his mentors, emphasized the importance of getting undergraduates involved in significant research. Srivastava embraced the challenge and produced findings that shed light on a poorly understood era of dinosaur evolution.
During the late Triassic period, dinosaurs shared their environment with early crocodile relatives and various species. Fossils from this time are scarce, making this discovery particularly significant. The reconstructed skull unveiled unique features, like broad cheekbones and a deep snout, indicating that early dinosaurs were experimenting with various forms long before they became the dominant species.
The Evolutionary Shift
The late Triassic was a crucial time in Earth’s history, characterized by fierce competition among species and followed by a mass extinction event. Srivastava noted, “Dinosaurs go from being co-stars to the headliner.” This period marked a significant ecological shift, with many rivals vanishing and allowing dinosaurs to flourish during the Jurassic.
The new species, named Ptychotherates bucculentus, suggests that its lineage survived longer than previously believed, perhaps until the extinction event itself. This discovery challenges existing views about dinosaur ecosystems, particularly in the American Southwest, which may have served as a refuge for these ancient predators.
Significance of the Discovery
The name Ptychotherates bucculentus translates to “folded hunter with full cheeks,” which reflects its unusual structure and the humor of one paleo-artist who referred to it as a “murder muppet.” Beyond the lighthearted remarks, the skull is crucial for understanding the evolutionary paths some dinosaurs took.
This single specimen has the power to transform our comprehension of early dinosaur life. As research tools become more advanced, it opens the door for discovering other overlooked fossils that may hold important secrets about our planet’s prehistoric past.

Every detail from this ancient skull helps clarify feeding habits, sensory abilities, and evolutionary adaptations. It’s a testament to the idea that even the most damaged fossils can reveal astonishing stories about Earth’s history.
