Cornwallius is an extinct herbivorous marine mammal of the family Desmostylidae. Cornwallius lived along the North American Pacific Coast from the Early Oligocene ( Chattian) through the Oligocene (28.4 mya—20.6 Mya) and existing for approximately 7.8 million years. [1] [2]
The type locality is the Chattian Sooke Formation, Vancouver Island, British Columbia, Canada ( 48°24′N 123°54′W / 48.4°N 123.9°W, paleocoordinates 48°00′N 115°00′W / 48.0°N 115.0°W). [2]
Cornwallius was named by Hay 1923. Its type is Desmostylus sookensis, named by Cornwall 1922 and recombined to Cornwallius sookensis by Hay 1923. [3]
Fossils have been discovered from Baja California Peninsula, Oregon and Washington coasts, and Unalaska Island. [4]
