About: Raeticodactylus   Sponge Permalink

An Entity of Type : owl:Thing, within Data Space : 134.155.108.49:8890 associated with source dataset(s)

Raeticodactylus had a tall thin bony crest running along the midline of the front of the upper jaw, and a keel on the lower jaw; however, it does not seem to be closely related to Austriadactylus, the only other crested Triassic pterosaur named by the time Raeticodactylus was described. The teeth at the front of the upper jaw, in the premaxillae, were fanglike, whereas the teeth in the upper cheeks (the maxillae) had three, four, or five cusps, similar to those of Eudimorphodon. Raeticodactylus had a wingspan of about 135 centimeters (53 in), and may have been a piscivore, potentially feeding by skimming the water.[1]

abstract
  • Raeticodactylus had a tall thin bony crest running along the midline of the front of the upper jaw, and a keel on the lower jaw; however, it does not seem to be closely related to Austriadactylus, the only other crested Triassic pterosaur named by the time Raeticodactylus was described. The teeth at the front of the upper jaw, in the premaxillae, were fanglike, whereas the teeth in the upper cheeks (the maxillae) had three, four, or five cusps, similar to those of Eudimorphodon. Raeticodactylus had a wingspan of about 135 centimeters (53 in), and may have been a piscivore, potentially feeding by skimming the water.[1] A 2009 study by Fabio Dalla Vecchia, which analyzed the relationships within the family Campylognathoididae, found that Raeticodactylus is very closely related to Caviramus. Caviramus is known only from a partial jaw, exhibiting the same type of teeth and unique cavities in the jaw bone, and both specimens come from the same time and place (the Alplihorn Member of the Swiss Kössen Formation). Dalla Vecchia concluded that the two belong to the same genus, and possibly the same species, if the subtle differences (such as size and the presence of a crest in the Raeticodactylus specimen) are not due to sex or age.[2] A study by Brian Andres e.a. from 2014 concluded that Raeticodactylus was the sister species of Caviramus within a Raeticodactylidae.
