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]
