I say that there are some differences in the two species ( a lot of these
are size related) but there are also a lot of similarities that unites the

Mainly so that you don't have to use two names to distinguish atherfieldensis
from bernissartensis. The genus is a Linnaean category that is as superfluous
as family, order, class, and so forth. Whether the differences between the
two species are regarded as specific or generic is entirely a matter of taste.
