Arambourgia
Extinct genus of reptiles
Arambourgia is an extinct monotypic genus of alligatorine crocodylian from Europe. It was named in 1905 as Allognathosuchus gaudryi. It was made a separate genus Arambourgia in 1940. This was synonymized with Allognathosuchus haupti in 1990[2] (now known as Hassiacosuchus haupti), but later reassigned as its own genus once again in 2004.[3] Arambourgia was likely to have been part of an early dispersal event of alligatorines from North America to Europe during the Eocene epoch. Arambourgia had non-serrated teeth and a deep orienirostral snout, unlike the flatter snouts of most other alligatorids.
Recent studies have consistently resolved Arambourgia as a member of Alligatorinae, although its relative placement is disputed, as shown by the cladograms below.[4][5][6]
