Extinct genus of marine crocodilians From Wikipedia, the free encyclopedia
Deslongchampsina is an extinct genus of machimosaurid crocodyliform from the Middle Jurassic (Bathonian) Cornbrash Formation of England and France, possibly from the Calcaire de Caen. The type and only known species is D. larteti, which was variously referred to Teleosaurus and the wastebasket taxon Steneosaurus before its distinction was formally recognised in 2019. Its snout was not as elongated as some other teleosauroids (mesorostrine), and the shape of its jaws and teeth suggest that it was a generalist predator, unlike the more powerful contemporary machimosaurin Yvridiosuchus.[1]
