Locality: McCoy, Eagle County, CO
Age: Pennsylvanian Period
Rock unit: Minturn Formation
Collector: W. Itano

This appears to be a fragment of the shell of a coiled nautiloid cephalopod. The curved lines are the septa. It is not identifiable, but is interesting because it shows that some relatively large coiled nautiloids are present at McCoy. (Scale in cm.)
