Zlichovaspis & Crotalocephalina Trilobites - Stunning Preparation

 
 
 
 
 
 
 
 
 
This is a stunning association of two different types of trilobites from the Lhandar Formation near Atchana, Morocco. There is a 3" long Zlichovaspis rugosa naturally associated with a similarly sized Crotalocephalina gibbus. They have been carefully prepared to remove the hard limestone surrounding the fossils leaving them in an aesthetic pose.

There is a small amount of shell restoration on the back of the head and first few axial rings of the Crotalocephalina.

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.
