Dolichochampsa

Dolichochampsa is an extinct genus of eusuchian crocodylomorph. It is the type genus and only member of the family Dolichochampsidae.^[1] Fossils have been found in the Yacoraite Formation of Argentina and the El Molino Formation of Bolivia of Maastrichtian age.^[2] It had a distinctive slender snout.^[3] Because the material associated with the specimens is so fragmentary, its relationships with other eusuchians remain unknown.^[4] Jouve et al. (2020) assigned Dolichochampsa to Gavialoidea, making it the oldest known South American member of this clade.^[5]
