NJ Cretaceous Shark Tooth

Recommended Posts

I found this shark tooth yesterday that I cannot seem to match with anything that is typically found in the Cretaceous brooks of Monmouth County, NJ. What has me baffled are the tiny serrations on the shoulders of the tooth enamel right next to the root. I tried to capture the serrations in the second photo. I wish more of the root was there, but it is what it is. The tooth is very small, roughly 1/4 inches. Any help is greatly appreciated.

It is most likely a contaminant Carcharhinus sp tooth. For some reason it also reminds me of an anterior Pseudocorax (but the serrations seem to large and irregular for it and also just looks different)... @non-remanié

@The Jersey Devil  Hi.  Have you found an pseudocorax before.  If so can you post a pic.  Would like to see one.  I know it is very rare to find one.

The serrations on the shoulders and along each side of the crown do look a lot like photographs out of Europe of Pseudocorax affinis. Given how rare they are in our area I have no idea what to think. I would love to hear other people's thoughts.

I have to agree that this tooth is a carcharhinid and either a contaminant (dropped by someone) or there is a Miocene or later deposit somewhere close that allowed this tooth to get mixed in.

Interesting. I have never heard of Miocene teeth getting mixed in with the Cretaceous teeth found there. I appreciate the advice.

Happens if there are many collectors around the area, someone loses a tooth
