Submitter notes: This photo is of a nice Eldredgeops crassituberculata collected this year on a 'Friend's' field trip to the LaFarge quarry at Paulding, Ohio due to the courtesy of their management. The prepared block is 10' or 26 cm long by 7' or 18.5 cm at the widest and 5 3/4' or 15 cm at the narrower end. The Trilobite is 2 7/8' (7 cm) long and 1 1/2' or 4 cm across the cheek. Some small areas of pyrite adhere to the shell and look like shale.
