Pair of Metacanthina (Asteropyge) Trilobites - Lghaft

This is a pair of 1.4" long Metacanthina issoumourensis trilobites often referred to as an "Asteropyge" or “Kayserops”. They were quarried near Lghaft, Morocco, and are about 2" apart from each other in the limestone. The piece is well prepared and they both display very aesthetically.

Trilobites were a very diverse group of extinct marine arthropods. They first appeared in the fossil record in the Early Cambrian (521 million years ago) and went extinct during the Permian mass extinction (250 million years ago). They were one of the most successful of the early animals on our planet: over 25,000 species have been described, filling nearly every evolutionary niche. Due in large part to their hard exoskeletons (shells), they left an excellent fossil record.
