The New York Times’ Trilobites column has a story about the discovery of a new dinosaur in Mexico. The animal, Xenovenator espinosai, was discovered in 2000 in the Cerro del Pueblo formation in northeastern Mexico by Martha Aguillón-Martinez. It lived about about 73 million years ago when the area was a marshy coastline. The animal’s description was published in the journal Diversity.

A team of paleontologists recently described a set of thick bones on top of the dinosaur’s braincase that fused together into a knobby bump. The scientists proposed that the new dinosaur, named Xenovenator (or “strange hunter”) espinosai, used the structure to ram into rivals. Their report was published this month in the journal Diversity.

“Raptorlike dinosaurs are often imagined primarily as agile predators using their claws and teeth,” said Héctor Rivera-Sylva, a paleontologist at the Museo del Desierto in Saltillo, Mexico, and the lead author of the paper. “Xenovenator reminds us that dinosaur behavior was likely far more diverse and nuanced.”
