Huge, 3" Spiny Kolihapeltis Trilobite - Rare Species
This is a HUGE, 3" long example of Kolihapeltis chlupaci hollardi from the Lhandar Formation near Atchana, Morocco. This might be the largest individual specimen of this species I've seen and it's a beautify. It's laid out prone with excellent preservation and only about 1-2% shell restoration along repaired cracks. All the spines have been prepared free-standing.
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 with over 25k currently described species, filling nearly every evolutionary niche. Due in large part to a hard exoskeleton (shell), they left an excellent fossil record.
