Fossil Spider, Florissant Formation 34 Million Years Old


0.26" (0.67 cm) fossil feather with insect from the Florissant Formation. From Teller County Colorado. 34 Million Years Old. Spider fossils are exceptionally rare not only in this site but the entire history of fossils. 

Found on private land just outside Florissant Fossil Beds National Monument. This area contains some of the best-preserved fossil leaves and insects in the world. These fossils have been preserved because of the interaction of the volcanic ash from the nearby volcano and the lake the animals and plants lived in.
