Yvridiosuchus
Yvridiosuchus (meaning "hybrid crocodile") is an extinct genus of machimosaurid crocodyliform from the Middle Jurassic (Bathonian) Cornbrash Formation of England and the "Sommet de la Grande Oolithe", Calvados, France. The type and only known species is Y. boutilieri. "Yvridiosuchus" is the oldest known member of Machimosaurini, a clade of large, predatory machimosaurids with powerful jaws and teeth. "Yvridiosuchus" was named on the basis that it has characteristics of both earlier machimosaurids and the derived machimosaurins, such as conical, blunt teeth. It co-existed with the more generalist machimosaurid "Deslongchampsina".
