Submitter notes: A large encrusting Bryozoan colony showing the individual bryozoa and the spaced bumps over the colony. A USA 25 cent piece is for scale. The whole colony is 3' (7.5 cm) by 2.5' (6.5 cm) by 2' (5 cm). There has been some question as to this being a sponge.

Submitted on 2009-06-06 by David Thompson
Location (approximate): Paulding, Paulding, OH
Strat unit: Silica formation
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.

Submitter notes: Since much of the material on this site is prepared, it was thought to show how this trilobite appeared when collected in the field. As you see, there is very little showing when many of these fossils are being collected.
