Myliobatis

See text Myliobatis is a genus of eagle rays in the family Myliobatidae.

[2] Their bodies consist of a rhomboidal disc, wider than long, with one dorsal fin.

[3] The teeth are arranged in the lower and upper jaws in flat tooth plates called pavement teeth, each consisting of about seven series of plates, which are used to crush clam shells and crustaceans.

Myliobatis species mainly feed on molluscs, bottom-living crustaceans, and small fishes.

[9] The extinct species Myliobatis dixoni is known from Tertiary deposits along the Atlantic seaboards of the United States, Brazil, Nigeria, England, and Germany.
