3.7" Spiny Dicranurus Trilobite - Atchana, Morocco

Spiny Dicranurus Trilobite - Atchana, Morocco #251447

This is a large, 3.7" wide example of the bizarre spiny trilobite Dicranurus monstrosus with its distinctive "rams horns". It was collected from the Lhandar Formation near Atchana, Morocco and is nicely prepared. There is a bit of disarticulation but the quality of preparation is extremely nice with only about 1% restoration in total.

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.
