These are Trilobite (species: Flexicalymene) fossils, just the way they come out of the ground, long before the first dinosaur with the fossil itself and the negative impression left in the matrix rock.

These approximately 400-million-year-old fossils from Morocco remain just as they are unearthed, with positive and negative geode halves – one side featuring the trilobite, the other its impression in the limestone matrix. A fun and unique gift idea for yourself or another fossil enthusiast.
