1.8" Bavarilla Trilobites With Preserved, Segmented Antennae

Bavarilla Trilobites With Preserved, Segmented Antennae #213196

This is a 1.9" Bavarilla trilobite with both antennae preserved. Preservation of soft parts on trilobites is extremely rare, but they are occasionally found in the Fezouata Formation of Morocco. The segmentation is clearly visible in both antennae. There is some restoration along a repaired crack, mainly the left cheek of the trilobite.

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: over 25,000 species have been described, filling nearly every evolutionary niche. Due in large part to their hard exoskeletons (shells), they left an excellent fossil record.
