1.4" Russian Dysplanus Trilobite - Rare Species

 
 
 
 
This is a nice specimen of one of the scarcer Russian illaenid trilobites Dysplanus acutigenia. It would be about 1.4" long if outstretched and is perfectly inflated. There is some shell weathering on the left hand side but no restoration.

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.
