Arhouriella is arguably the oldest example of a bivalve mollusc in the fossil record. Arguably because there are older contenders to this crown, and because there is not a watertight case that it is a bivalve.^[2] The type and only species, Arhoruiella opheodontoides, was named and described by Geyer & Streng in 1998.
