ID for Ramanessin Brook Teeth

[PaleoNoel]

Back in 2016 I went fossil hunting in Ramanessin Brook, New Jersey. I found plenty of shark teeth as usual (Squalicorax, Scapanorhynchus, Archaeolamna etc.) and a few small invertebrates. But two teeth looked different from the rest. Since then I have just referred to them as fish teeth but I'm not sure how accurate that is. Mosasaur teeth are apparently found regularly at Ramanessin and I have heard of people finding crocodile teeth as well. The potential reptile tooth is very small, which is what made me think that it came from a fish originally. I'm not sure what the more striated tooth belongs to but it could come from a Xiphactinus or be a sawfish rhostral spine. If anyone could help me out in identifying these fossils that would be great

I don't see any tooth enamel on that specimen. I think it is most likely a tooth-shaped concretion with a very slight possibility of being an extremely worn mosasaur tooth or bone fragment. If I had a dollar for every suggestively shaped concretion I've handled from the brooks, well.

The first one looks like it could be a split tooth, likely reptilian.  The second looks like a partial, eroded Enchodus tooth.   The pictures arent quite sharp enough to be definitive, however.

The first one is either a crocodile tooth or a Mosasaur tooth, but most likely a Mosasaur tooth because it is common for them to be split in half.

The second is a sawfish rostral spine blade. The last pic of the broken end shows that it has a hole in the center which is typical of broken rostrals.

Thanks for replying. I certainly know the feeling of pick up a tooth shaped concretion and being disappointed by finding out what it really is. It may be the quality of the image, but I can see the shine of enamel when I hold both pieces under light.

Thanks! I was hoping it would be a Mosasaur tooth as I have no others in my collection (despite several trips to Big Brook and Ramanessin Brook). And it's great to know the identity of the other fossil as well.
