2.9" Dicranurus Trilobite - Free Standing Spines!

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, and ones of this quality don't come around very often.

This is a top quality specimen with excellent preparation. All of the spines have been meticulously free-stood, a very time consuming task. The only restoration on the specimen is just some minor shell touchups.

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.
