• South America ( Argentina, Brazil)

The Baurusuchidae are an extinct lineage of Mesoeucrocodylia, land-dwelling relatives of crocodiles, and was home of the Upper Cretaceous to Eocene in the South America and the Indian subcontinent.

First description and definition

The taxon Baurusuchidae 1945 were described by Llewellyn Ivor Price scientifically. He established and defined the taxon based on the type species Baurusuchus pachecoi. This Crocodylomorpha have an elongated skull, which is laterally compressed. The square legs are upright and the secondary palate leg belongs to the type of Mesosuchia to. The dentition is differentiated with a tendency to an extreme reduction of ziphodonten teeth ( long, laterally compressed, recurved at margins and serrated blades ), especially in the maxilla. The Ektopterygoiden are large and have a share in the edges of the inner nostrils.

Dissemination

Fossils of terrestrial hyperkarnivoren Crocodylomorpha come from South America (Argentina and Brazil) and from the Indian subcontinent (Pakistan ).

System

The Baurusuchidae form a group within the subordination of Notosuchia. This group includes by definition the common ancestor of Baurusuchus and Stratiotosuchus and all of their descendants. The following genera are counted among the Baurusuchiden:

• Baurusuchus - Turonian to Santonian - Brazil ( Adamantina Formation)
• Bergisuchus - Eocene - Brazil
• Cynodontosuchus - Coniacian to Santonian - Argentina
• Pabwehshi - Maastrichtian - Pakistan
• Stratiotosuchus - Turonian to Santonian - Brazil ( Adamantina Formation)
• Wargosuchus - Santonian - Argentina
