Synonyms: Raeticodactylus filisurensis?
Classification: Chordata, Reptilia, Pterosauria, Campylognathoididae.
Species: C. schesaplanensis (type).
Size: 135 centimetre wingspan.
Known locations: Switzerland - Kössen Formation.
Time period: Norian to Rhaetian of the Triassic.
Fossil representation: 2 specimens, one of which is a partial skull with partial post cranial remains.
little was known about Caviramus when it was
discovered as it was only
known from a ramus (part of the side of the lower jaw) and two teeth.
This lack of knowledge continued until 2009 when another pterosaur
the same area, Raeticodactylus, was found to have
been identical to the
fragment of Caviramus. Since Raeticodactylus
was named in 2008, it then
became a junior synonym to Caviramus. With more
material a more
complete picture of Caviramus can be pieced
Caviramus had a varying dentition in its mouth with sharp fang like teeth at the front of the mouth being used presumably for prey capture. The teeth at the back however were multicusped, with different teeth having between three to five cusps each. Such a cusped dentition is similar to that seen in another Triassic pterosaurs name Eudimorphodon. The addition of new material has also revealed the presence of a crest on top of the head.
Caviramus is thought to have hunted for fish as opposed to insects by its size and the differing dentition in its mouth.
