Cephalon from Ogilvie Mtns.

Here's one of the head shields from the same location , which I don't think has any relation to the previously posted spiny pygidium ... This is the only type of cephalon I've recovered from that spot.

Looks like some sort of harpid, perhaps along the lines of Scotoharpes.  Very cool trilobite. :wub:

We posted simultaneously.  Unfortunately I was handicapped with pesky citations, figures and links!  :o :P lol
