Trematochampsidae
Trematochampsidae is an extinct family of mesoeucrocodylian crocodylomorphs. Fossils are present from Madagascar, Morocco, Niger, Argentina, and Brazil (in the case of ''Caririsuchus'', where some specimens have been found in the Romualdo Member of the Santana Formation〔Kellner, A.W.A. and Campos, D. A. (1999). Vertebrate Paleontology in Brazil - a review. ''Episodes'', vol. 22, p. 238-251.〕). 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.〔Buckley, G. A., and Brochu, C. A. (1999). An enigmatic new crocodile from the Upper Cretaceous of Madagascar. In Unwin, D. (ed.), Cretaceous Fossil Vertebrates: Special Papers in Palaeontology No. 60, The Palaeontological Association (London), p. 149-175.〕 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.〔Rogers, Raymond R.; Krause, David W.; Curry Rogers, Kristina; Rasoamiaramanana, Armand H.; & Rahantarisoa, Lydia. (2007). Paleoenvironment and Paleoecology of Majungasaurus crenatissimus (Theropoda: Abelisauridae) from the Late Cretaceous of Madagascar. ''Journal of Vertebrate Paleontology'' 27(sp8): 21-31.〕
