Pachycentrata is an extinct genus of frogs.
Pachycentrata fossils have been found in the In Beceten Formation located in Tahoua, Niger. [1] The fossils have been dated to the late/upper Coniacian to Santonian periods. [2] It is estimated to have snout-vent length about 7 centimetres (2.8 in). [1] The original phylogenetic analysis suggested that it was more closely related to Pipa than to Xenopus , [1] and a recent phylogenetic supports this conclusion in an unconstrained phylogenetic analysis, but constraining for the topology obtained by molecular studies [3] [4] yields less resolved results that place Pachycentrata in an unresolved polytomy with extant pipids and several extinct pipimorphs.
