Keichousaurus - is a genius of marine reptile in
the pachypleurosaur family, which went extinct at the close of the Triassic period. About 220 + million years ago. The name derives from Kweichow, an achient provience in China.
Keichousaurus, like all sauropterygians, was
highly adapted to the aquatic environment. Individuals of this genus ranged
from 15 - 30 cm in length, and had both long necks and long tails, with
elongated, five-toed feet. The pointed head and sharp teeth in this genus also
indicate that they were fish- eaters.
