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.[5]
