Two-Tone Paralejurus Trilobite
This trilobite comes from the Paralejurus genus. It has a white calcite stripe going across it, a sign of the geologic processes that it has undergone, with one side of the stripe being a brown, and the other side being black.
While living, this trilobite would have been approximately 91mm long by 42mm wide.
The base is approximately 117mm by 135mm, and the entire display is 38mm tall.
Trilobite means “three lobes” referring the three distinct parts distinguished on their bodies. They are among the earliest known arthropods, and were some of the most successful of all early animals, existing for over 270 million years. They are first known in the fossil record from the Early Cambrian (521 million years ago) and went extinct at the end of the Permian about 252 million years ago. Their exoskeleton was readily fossilized, leaving behind an extensive trilobite fossil record of over 17,000 species. This diversity leads trilobite fossils to become some exceptionally beautiful and unusual specimens.
The Trilobites of Morocco are preserved in limestone, which allowed the fossils to be preserved in all 3 dimensions, without the flattening that can sometimes occur with other trilobites. They are extracted from the limestone by breaking open the rock to find a trilobite, and once evidence of one is found, paleo tools and dentists pics are used to remove the limestone while leaving the trilobite behind. Our team of preparers work directly with the Tahiri Museum in Erfoud and are amongst the best trilobite preppers in the world.
