 Description:
This unusual trilobite is a rarely offered member of the genus Tropidocoryphe,
The family derives it names from a feature found in proetids termed
the tropidium, a line of pits in the glabella that may have served
a sensory function. The genus shares a number of features with the
more familiar Cornuproetus (see my other offerings) but differs in
the possession of longer genals and a set of axial spines. To date
it is the only member of the genus to possess spines on the axial
lobe, a feature well displayed here. This one was described by Chatterton
et. Al. in 2009. As of the publication of the species only two complete
examples were known, but several more have come to light recently
in this newer location.
