This week, we have a trilobite for Fossil Friday. Calymene celebra is a common trilobite found in Illinois, Indiana, and Wisconsin. It lived during the Silurian Period, which lasted from about 443 to 419 million years ago. This species belongs to the order Phacopida. This specimen is preserved in Niagara dolamite and was discovered in a quarry near Kankakee, Illinois back in the 1990's. C. celebra was designated as the state fossil of Wisconsin in 1985.
