Trematochampsidae

Trematochampsidae is an extinct family of mesoeucrocodylian crocodylomorph. Fossils are present from Madagascar, Morocco, and Brazil (in the case of Caririsuchus, where some specimens have been found in the Romualdo Member of the Santana Formation ). Possible trematochampsids have been found from Spain and France, but classification past the family level is indeterminant. The trematochampsids first appeared during the Barremian stage of the Early Cretaceous and went extinct during the late Maastrichtian stage of the Late Cretaceous.

Description
Trematochampsids are deep-snouted and have a ziphodont tooth structure. The dentition differs from most other crocodilians in that the teeth are recurved, serrated, and lateromedially compressed. This may be an adaptation to a terrestrial or at least semiterrestrial lifestyle as such teeth would be better suited for cutting and tearing into prey as opposed to capturing them and holding them underwater. Despite this, most trematochampsids are presumed to have been aquatic.

Taxonomy
There has been much controversy surrounding the family's phylogeny, and the group's monophyly has been questioned. Relations between taxa within the family are also poorly understood. Many crocodylomorphs such as Mahajangasuchus, Bergisuchus, Iberosuchus, and Itasuchus had originally been assigned to Trematochapsidae but have since been assigned to the family Sebecidae or put into their own families. Neogene sebecosuchians of Europe have been reclassified as trematochampsids but have recently been supported as true sebecosuchians as was originally proposed.
