In Depth Liaodactylus is a genus of pterosaur that lived in Asia during the late Jurassic. Liaodactylus is noted for having numerous small teeth in comb-like structures that meshed together when the jaws closed. This would have allowed Liaodactylus to feed by filtering out small invertebrates from water and soft sediment. Further Reading - Earliest … Read more
In Depth Ctenochasmatid pterosaurs are usually confirmed by their special dentition which allows them to filter sediment and water as they hunt for invertebrates. However this was not possible for Beipiaopterus because the skull was unknown. Instead the remainder of the body had to be examined for identifying features and the conclusion to this was … Read more
In Depth The discovery of Pterodaustro was a fantastic find, as not only was it the first pterosaur to be discovered in South America, here was a pterosaur that filtered for food in a similar manner to a modern day flamingo. This is evidenced by the strongly upwards curing beak that instead of having more … Read more
In Depth When first described in 1833, Gnathosaurus was actually thought to have been the remains of small prehistoric crocodile. This persisted until the discovery of the skull in 1951, which revealed Gnathosaurus to actually be a filter feeding pterosaur similar to Ctenochasma. The teeth of Gnathosaurus were very fine and projected outwards from the … Read more
In Depth Cathayopterus is another member of the filter feeding group of pterosaurs that are known from all over the world with particularly notable genera hailing from South America (Pterodaustro) and Europe (Ctenochasma).

In Depth Ctenochasma is one of the few known filter feeding pterosaurs, and its name heads up the group Ctenochasmatidae which includes similar pterosaurs such as Pterodaustro and Unwindia. The method of pterosaurs filter feeding is quite simple as instead of having the large needle like teeth associated with catching fish and insects, pterosaurs like … Read more
