Caviramus is a genus of "rhamphorhynchoid" pterosaur from the Late Triassic (late Norian-early Rhaetian-age) lower Kössen Formation of the Northern Calcareous Alps of Switzerland.
The genus was in 2006 named by Nadia Fröbisch and Jörg Fröbisch. The type species is Caviramus schesaplanensis. The genus name is derived from Latin cavus, "hollow" and ramus, "branch". The specific name refers to Mount Schesaplana.
The genus is based on holotype PIMUZ A/III 1225, three non-contiguous fragments of a ramus (lower jaw) of the mandible with multicuspate teeth. Two teeth are preserved, one with three cusps, and one with four; despite this difference the authors consider them as essentially isodont. The number of teeth is estimated at a minimum of twelve and a maximum of seventeen. A row of large oval runs parallel to the tooth row; foramina in the form of small holes in the anterior part of the lower jaw suggest some sort of soft-tissue structure, or a keratin covering. The jaw is light and hollow. The teeth of this genus resemble those of Eudimorphodon, but the jaw is different. The discovery of this genus is a find of some significance, as there are few pterosaurs known from the Triassic.
