American Student Finds Rare Marsupial Jawbone
An American student working with the North Dakota Geological Survey has found a very rare and exceptionally well preserved fossilised jawbone of a Late Cretaceous mammal. The Cretaceous of North American may have sported mega fauna such as Tyrannosaurus rex and Triceratops but there was also a rich and diverse mammalian fauna. The fossil has been identified as a jawbone (complete with six tiny teeth), of a marsupial mammal named Glasbius twitchelli. The fossil is approximately sixty-five million years old and it represents the most complete lower jawbone found for this species.
