Well Preserved 2.4" Thysanopeltis Trilobite
This is a 2.4" long example of the Middle Devonian trilobite Thysanopeltis speciosa from Mount Issoumour, Morocco. What is so distinctive about this trilobite is the fringe of pygidial (tail) spines. It's nicely outstretched and displays beautifully on the matrix.
