The name Ctenochasma (meaning "comb jaw") was given to this group of pterosaurs by German paleontologist Christian Erich Hermann von Meyer, in 1852, based on a single lower jaw filled with closely packed teeth. The distinguishing feature of Ctenochasma is the numerous long thin curved teeth (over 400) in adults). Those teeth were so closely packed that they formed a comb. In adults the teeth projected outward from the jaws, forming a basket. It is thougt that these features indicate a filter feeding lifestyle. By straining water through its teeth it could capture and eat small invertebretes. Additionally, the front of the jaw had a spatulate profile indicationg that it had a spoonbill-like lifestyle. The increased surface of the jaws allowed it to catch small prey. The snout curved upward slightly and the teeth were restricted to the front half of the jaws. Dimensions: 11-3/4" x 9-1/2" 1-1/2"
