It is not so much the size of the serrae as the shape of the serrae, being
low, and nearly quandrangular, along with size distribution along the carinae.
The shapes oft he teeth are also very coincident, with all teeth attributed to
this genus being relatively straight with minimal recurvature. The *R.
isoceles* teeth are just less recurved and in fact less recumbent than the
teeth attributed to *R. gilmorei*.
