Caviramus is a pterosaur genus from the Late Triassic period, specifically from the early Rhaetian stage, residing in the lower Kössen Formation within the Northern Calcareous Alps of Switzerland. This pterosaur falls into a group that includes other early aerial reptiles like Eudimorphodon, which thrived during the Late Triassic. These genera, along with possibly a few more, collectively form the Eudimorphodontidae, a family primarily comprised of small, long-winged terrestrial pterosaurs.

These pterosaur remains were unearthed in the Kössen Formation of the Swiss Alps. The name of the sole known species, C. schesaplanensis, pays tribute to Mount Schesaplana, the specific area where these fossils were discovered. This discovery is dated to the very end of the Triassic Period when pterosaurs had already become accomplished and skilled flyers.

The estimated wingspan of this creature is approximately 1.35 meters. However, this genus isn't the most well-documented, and there have been challenges in confidently reconstructing its appearance. The holotype was initially named by Nadia and Jorg Frobisch in 2006 and was described based on a lower jaw containing teeth.

Additional skull fragments hint at the likelihood of Caviramus having some form of keratinous crest on its head. Based on its size and dental structure, it is assumed that Caviramus primarily preyed on fish, rather than insects.
