Anthropologists from the University of Bath have identified the remains of a horned dinosaur that was about the size of a large dog, and that lived several million years ago in the Appalachia, also known as the lost continent.

The fossil is thought to be for an animal that lived during the Late Cretaceous period 66-100 million years ago, when the Western Interior Seaway divided North America into two continents. Western continent was divided from Asia, and the dinosaurs living on this side from those living on the other side.

Dr. Nick Longrich of the Milner Centre for Evolution at the University of Bath's Department of Biology and Biochemistry examined the fossils of discovered remains at the Peabody Museum at Yale University. He identified the jaw bone of the Ceratopsia or horned dinosaurs and got his work featured in the journal Cretaceous Research.

The ceratopsia was identified to be a plant-eater and could have been a cousin to Triceratops.

"Just as many animals and plants found in Australia today are quite different to those found in other parts of the world, it seems that animals in the eastern part of North America in the Late Cretaceous period evolved in a completely different way to those found in the western part of what is now North America due to a long period of isolation,” Dr. Nick Longrich explained.

"This adds to the theory that these two land masses were separated by a stretch of water, stopping animals from moving between them, causing the animals in Appalachia to evolve in a completely different direction, resulting in some pretty weird looking dinosaurs,” he added.

Longrich noted that searching and analyzing fossils of the Cretaceous period when the Earth was fragmented made running experiments on dinosaur revolution disjointed. This is largely because land masses of Europe, South America, eastern North America, Africa, Australia, and India were cut off by water.

"Each one of these island continents would have evolved its own unique dinosaurs- so there are probably many more species out there to find," he concluded.
