306.95 – 300.2 MYA
Catalog Number: CG-0102
A quick post as this specimen has much more work needed done before I can do a full write up. In the local stream there is a junction where two streams meet and turn into one. A piece of loose limestone, laying in the stream bed, was easily split. It had been saturated for quite some time and was full of fossils. Progressively making it smaller, I revealed the labial side of the specimen. I have not found a new Petalodus tooth since the specimen I found in the Pine Creek Limestone.
This side was a silver color. In trying to cleave the rock to a smaller size for transport, one quarter of the left labial side broke off. This same action also freed the remaining crown. I brought these two pieces and the mold back. The corner is going to be difficult to remove without breaking it. If I can manage to remove it, then I can glue it back to the larger piece.
Unique to the fourteenth tooth
One unique feature is the apex of the crown. Instead of coming to a clean angle, the apex comes up at a slightly sharper angle. The lingual side of the tooth is more brown color compared to the other side. The root did not appear easy to obtain.
Additional photos of Petalodus ohioensis XIV.
I will post additional photos in the future. The plan is to reattach the left labial side. I need to spent some time figuring out how to remove it from the matrix.
