Found a Pennsylvanian age shark today!

Today turned out to be a good day to go through Linton Cannel Coal. I haven't searched the fossil coal in a while. Just for fun, I was looking through some blocks when I spotted a shark spine buried in a thin layer of spore cannel. Usually when I split the coal, I use a knife, but this piece was so thin and fragile I decided to blow of the layer with an air nozzle. When I did this, not only did I see a spine, but nearly a complete Shark was there. Typically the size of the coal block limits the fossil size. Today's fossil Orthacanthus compressus was missing the head and the tip of the tail. Sigh.  This shark is from a coal mine in SE Ohio. The coal is Upper Pennsylvanian in age (300 myo). I have included a sketch of what an Orthacanthus may have looked like.

Awesome find, John!  :wub: 

Thanks for posting it. 

 

I hope you don't mind, I took the liberty of brightening the first two pictures.

That's one of the best (if not the best) Linton xenacanth I've seen. Might consider donating this to a museum.

What a great find, and a nice tool to help all of us to learn something about shark fossils. Even if you decide not to donate it I'm sure Dr. Maisey at the AMNH would love to have a look and maybe take some measurements. These are his specialty.

Wow. Fantastic find. Learned something new today and that from someone who has found 10s of 1000s of shark teeth.  Thanks very much for sharing and Kudos to  @fossildude for the enhancements. :fistbump:

Personally I would recommend the Carnegie Museum in Pittsburgh as they currently maintain the biggest Linton collection.
