This is a good example of Eodalmanitina sp. from the Ordovician of Portugal. The trilobite is well articulated. The large eyes are quite evident. Even the short caudal spine is discernible. The orange-colored trilobite is well centered on a semi-rectangular block of gray matrix. There is also an impression of another trilobite on the slab. This is a very nice, affordable Eodalmanitina from Portugal.
