dol1chosaurus

[Gr. dolichos =long, and sauros a lizard.] Palcont.: A small snake-like Lacertilian reptile, between one and two feet long, whose remains have been found in the chalk formation. It was remarkable for po e ing a very small head and long slender neck, but in other respects its affinities were truly Lacertilian. Its abdomen was deep and narrow, like that of the water snakes (Hydro phi des), which it also resembled in habits, being aquatic, and swimming by undulatory lateral movements of its long body.
