Extract

Coniasaurus Owen, 1850 was a small (50–100 cm in length) marine lizard that has been sporadically reported from Late Cretaceous marine deposits of Germany, England, and the United States. These deposits were formed throughout the basins of the Tethys and Western Interior Seas (Diedrich, 1997; Caldwell, 1999; Caldwell and Cooper, 1999; Liggett, 2004). Coniasaurus is thus far known only from incomplete specimens. However, sufficient material exists to show that it possessed four short limbs and an elongated skull, neck, trunk, and tail, and was equipped with a specialized dentition (Caldwell and Cooper, 1999). Caldwell and Cooper (1999) inferred that Coniasaurus likely occupied a niche similar to small sauropterygians.
