Japan's dinosaurs

[crpntr@ix.netcom.com (Kenneth Carpenter )]

Regarding the nodosaur from Japan, it consists of the rear portion of 
the skull, some jaw material and teeth that are clearly nodosaurid. It 
is from a marine limestone from the northern island, Hokkaido. Mesozoic 
terrestrial and marine sediments occur in isolated basins throughout 
Japan. Except for the nodosaur, the dinosaurs show affinities with 
mainland Asia. Japan apparently separated from Asia sometime in the 
Cenozoic. Drift may have been south relative to China producing the Sea 
of Japan.
