connorp Posted September 1 Share Posted September 1 I collected this trilobite from the Massie Shale (Silurian) in Indiana. It has no rostrum, which made me think it was Calymene at first. However it has some disarticulation, so perhaps it is a Spathacalymene with no rostrum. The furrows on the pygidium don't appear to extend to the margins, which I believe suggests Spathacalymene. A second opinion would be appreciated though. 6 Link to post Share on other sites
