New Dinosaur Species Discovered in North America

The newly identified Eoneophron infernalis, part of the Oviraptorosaurs group, lived just before the mass extinction event 66 million years ago.

Scientists have discovered a new species of dinosaur, named Eoneophron infernalis, which lived in North America just before the mass extinction event around 66 million years ago.
The new species is part of the Oviraptorosaurs group, which were bird-like dinosaurs, and it stood roughly 3 feet tall at the hip and may have weighed between around 130 and 216 pounds.
Eoneophron infernalis, also known as the 'Pharaoh's dawn chicken from hell,' lived at the very end of the Cretaceous, between 68-66.5 million years ago.
The fossils of this new species were initially uncovered in Meade County, South Dakota, which forms part of the Hell Creek geological formation.
The discovery of this new species, along with evidence for a third, as yet unnamed caenagnathid species, suggests that this group of dinosaurs was not decreasing in diversity during the end of the Cretaceous period.
