Natural History:

Remarks:
Bufo pliocompactilis was based on disassembled remains (holotype UMMP Ann Arbor V55430, frontoparietal) from the Upper Miocene Wakeeney site (Kansas, U.S.A.) (Wilson, 1968). It is considered as a nomen dubium, either being a valid extinct species or a possible synonym with respect to the living Anaxyrus compactilis (Wiegmann, 1833) by Sanchiz (1998a) or Anaxyrus speciosus by Frost (2011). The iliac morphology is not diagnostic, as it has a set of characters that overlaps with several living species, many of which are within Anaxyrus, but also a few within the genus Incilius (Bever, 2005). Martin et al. (2012) proposed the new combination Anaxyrus pliocompactilis (Wilson, 1968) as the most appropriate name for further taxonomic analysis.
