Blacksburg, Virginia – A mangled dinosaur skull, unearthed over four decades ago and long overlooked, has revealed a new species of early meat-eating predator. Virginia Tech geosciences senior Simba Srivastava led the analysis that identified the fossil as belonging to one of the last survivors of the Herrerasauria family from the Triassic period’s close. This discovery, detailed in a recent scientific publication, offers fresh insights into dinosaur evolution just before a massive extinction reshaped life on Earth.

In 1982, a team from the Carnegie Museum of Natural History excavated the crushed skull at New Mexico’s Ghost Ranch, within the famous Coelophysis Quarry. The specimen, a lumpy and pockmarked remnant, languished in storage until geobiologist Sterling Nesbitt rediscovered it more than 30 years later. Nesbitt brought the fossil to Virginia Tech, where he and colleague Michelle Stocker enlisted Srivastava as a first-year student to tackle the challenging project.
Srivastava described the fossil bluntly: “This is a uniquely sucky specimen.” Despite its poor condition, the small skull—small enough to fit in one’s hands—held untapped potential. Over two years, the team committed to unlocking its secrets, marking a classic case of undergraduate drive turning a forgotten rock into a scientific milestone.
High-Tech Reconstruction Unlocks the Past
The researchers employed computed tomography (CT) scans to digitally disentangle the fossil’s flattened bones. This process allowed them to isolate individual elements and produce a 3D-printed model of the skull. Such advanced techniques transformed what might have been dismissed as worthless into a clear window on ancient anatomy…
