History

Hemiprotosuchus was named by Argentinian paleontologist José Bonaparte in 1969. The type species is H. leali.^[1] The fossils included a skull and jaws as well as some postcranial elements.^[2]

A 2009 cladistic analysis of protosuchids by paleontologist Eric Buffetaut et al. found that Hemiprotosuchus was the sister taxon of Protosuchus.^[3]
