Description : Here is a very detailed specimen of Phacopina micheli from the Ordovician of Portugal. This classic trilobite is extremely well articulated and almost perfectly prone. The bug is quite inflated and very aesthetic in appearance. The large compound eyes have almost the full complement of facets intact. The natural brown color of the trilobite contrasts wonderfully with the grey matrix. The trilobite is nicely centered on the oval block of rock. This is a very fine example of this well-known European trilobite.
