Bargain Hollardops Trilobite - 2.3" long
This is a inexpensive example of the Middle Devonian trilobite Hollardops mesocristata from Mount Issoumour, Morocco. It's 2.5" long and laid out nice an prone. There's probably 5% restoration to it, but it's still fairly detailed and you can see good eye facets in the left eye.
