Kainops & Partial Lochovella (Reedops) Trilobites - Oklahoma
This is a pair of beautiful, phacopid trilobites from the Haragan Formation of Oklahoma. There is a partial Lochovella (Reedops) deckeri which is 1.4" long but missing it's tail and a smaller, partially enrolled Kainops. The carmel colored preservation contrasts nicely with the creme colored rock and the rock has been sculpted so that it displays nicely without the need for a display stand.
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.
