2.5" Dicranurus Trilobite - Top Quality Preparation!

This is bizarre trilobite looks like something you might see in an Aliens movie. It's fittingly named Dicranurus monstrosus. While fakes of this trilobite abound, real examples like this one are fairly rare.

This is a top quality specimen with excellent preparation and only about 1% restoration. All of the spines have been meticulously free-stood, a very time consuming task. You won't find a nicer specimen of this spiny monster than this one.

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 described species, filling nearly every evolutionary niche. Due in large part to a hard exoskeleton (shell), they left a excellent fossil record.
