What is "atlantosuchus"

Atlantosuchus is an extinct genus of dyrosaurid crocodylomorph from Morocco. One defining characteristic that distinguishes it from other long-snouted dyrosaurids was its proportionally elongate snout, the longest in proportion to body size of any dyrosaurid. Rhabdognathus, a hyposaurine dyrosaurid, is believed to have been the closest relative of the genus.
