Shark, Fish And Other Micros From Lee Creek Mine Matrix

Recommended Posts

I recently had a chance to sift through some matrix from the Lee Creek Mine (Aurora, NC).

Here are my best guesses for IDing what I found. Please feel free to correct me in any identifications.

Identification of the mollusks (17-21) was greatly assisted by the following USGS pubs:

"Mollusca from the miocene and lower pliocene of virginia and north carolina: Part 1 pelecypoda"

http://pubs.er.usgs.gov/publication/pp199A

"Mollusca from the miocene and lower pliocene of virginia and north carolina: Part 2 scaphopoda and gastropoda"

http://pubs.er.usgs.gov/publication/pp199B

Nice finds! The shells are in very good condition. I don't know enough to be able to offer IDs, but enjoy looking at your finds. I do know the Lagodon and the Dasyatis are right, as I have found those too. :)

Excellent, clear photography; such a presentation allows the viewer to really appreciate the pictured fossil.

Human beings, who are almost unique in having the ability to learn from the experience of others, also are remarkable for their apparent disinclination to do so. - Douglas Adams, Last Chance to See

Nice pictures. I do not think #2 is Rhizoprionodon. Are there serrations on the crown beyond the shoulders? I do not believe #3 is Carcharias sp. It looks like Anomotodon which really isn't reported from Lee Creek. Can you take a picture of the labial view? #7 & 8 are difficult to id from a picture because there are just so many possibilities. #9 being serrated is probably a lower Carcharhinus sp. like C. leucas or C. longimanus.

Here are front and back pictures of what was originally #2. I'm not sure about the serrations you asked about.

Here are front and back pictures of what was orginally #3.

It looks like tooth #2 has serrations in the areas in the red circles in the below picture. If it does it is probably a Carcharhinus sp.

The areas of tooth #3 that I needed to see in the black circles are damaged. I can't tell if cusplets are broken off or if the tooth just had a shoulder. Although your tooth did look like an Anomotodon from the lingual picture, Anomotodon is an Eocene/Oligocene species which shouldn't be found unless reworked at Lee Creek.
