Archovember Day 24: Cricosaurus suevicus
Last year I drew Dakosaurus, and now it’s time for its skinny cousin Cricosaurus to take the spotlight.
Cricosaurus is a genus of long-snouted Metriorhynchid crocodyliform fully adapted to marine life. Like most other Metriorhynchids, it had paddle-like feet, a tail fluke, and smooth skin. Cricosaurus adults and juveniles both had well-developed salt glands, which allowed them to drink salt water and eat seafood without dehydrating. It also seemed to have a large pelvic opening which would have allowed it to give live birth.
Cricosaurus suevicus shared its territory with a variety of other marine crocodylomorphs in the Late Jurassic ocean which would one day be Germany. It is suspected that this was possible due to niche partitioning: larger, short-snouted metriorhynchids like Dakosaurus and Geosaurus would have been the apex predators, while smaller, long-snouted species like Rhacheosaurus and Cricosaurus, as well as the teleosaurid Steneosaurus, would have preferred different types of fish. Cricosaurus suevicus was about 6 feet long.
There were at least 11 species of Cricosaurus, but I chose Cricosaurus suevicus because I liked the pose of its fossil. 😅
