Catalog Number: CG-0087
This is the first specimen of Petalodus ohioensis I have recovered from Pine Creek Limestone. Specimens of Petalodus can be found in marine zones throughout the Glenshaw Formation, so finding one here is no surprise. However through several trips to the locality, which is around 10 miles North East from our own local section, I’ve never found any evidence of P. ohioensis there until yesterday (July 11, 2020).
Specimen in-situ in larger piece of Pine Creek Limestone
In reducing the boulder into smaller pieces, one such break revealed this dark black tooth brown. Most specimens recovered have a bright silver to white color. However, the coloring here was not unusual. With the high organic content within the rocks, this is not unusual to find anything colored black within.
