''Pachycentrata'' is an extinct genus of frogs. ''Pachycentrata'' fossils have been found in the In Beceten Formation located in Tahoua, Niger. A. M. Báez and J.-C. Rage. 1998. Pipid frogs from the Upper Cretaceous of In Beceten, Niger. Palaeontology 41(4):669-691 The fossils have been dated to the late/upper Coniacian to Santonian periods. It is estimated to have snout-vent length about . The original phylogenetic analysis suggested that it was more closely related to ''Pipa (frog), Pipa'' than to ''Xenopus'', and a recent phylogenetic supports this conclusion in an unconstrained phylogenetic analysis, but constraining for the topology obtained by molecular studies yields less resolved results that place ''Pachycentrata'' in an unresolved polytomy with extant pipids and several extinct pipimorphs.
