Tropidocoryphe amuriDescription: This is a rare trilobite 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, 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 posses spines on the axial lobe, a feature well displayed here. This one was resently described by Chatterton et al. in 2009. As of the publication of the species, only two complete examples were known.
