Order Proetida, Superfamily Proetoidea, Family Tropidocoryphidae
is 24 mm long
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
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
examples were known.
