Summary
[edit]DescriptionJuvenile Ctenochasma elegans - Pterosaurs Flight in the Age of Dinosaurs (43104269580).jpg |
Cast of a fossil juvenile Ctenochasma elegans. On display as part of the exhibit "Pterosaurs: Flight in the Age of Dinosaurs" at the Cleveland Natural History Museum in Cleveland, Ohio, in the United States. The smallest of the Ctenochasma, C. elegans had a wingspan of only about 9.8 inches. Its mouth contained as many as 260 long, thin comb-like teeth which acted like a comb. C. elegans probably fed by scooping up moutfuls of water, then filtering out the water through its teeth and eating the animals caught. Adult Ctenochasma had a bony crest along the skull, though this is not found in juveniles. This fossil was found in the Solnhofen Limestone of Bavaria, Germany. It dates to about 150 million years ago, and is held by the American Museum of Natural History. |
