Late Cretaceous, 75 million years ago
Einiosaurus, meaning “buffalo lizard,” is a genus of ceratopsian dinosaur that lived during the Late Cretaceous period, approximately 75 million years ago, in what is now Montana, United States.
Einiosaurus was a medium-sized herbivorous dinosaur, with a distinctive forward-curving horn on its nose and a pair of long, curved horns above its eyes. Its frill, the bony structure at the back of its skull, was relatively short and broad, with triangular projections along its edge.
The discovery of Einiosaurus has provided important insights into the diversity and evolution of ceratopsian dinosaurs during the Late Cretaceous period. Its physical characteristics suggest that it was a relatively specialized species that was adapted to its environment and ecological niche.
Despite its importance, relatively few fossils of Einiosaurus have been found, making it a relatively poorly known dinosaur. Nonetheless, it remains a fascinating and important species for scientists and dinosaur enthusiasts alike, offering important clues into the complex ecosystems and evolutionary processes of the Late Cretaceous period in North America.
