Help ID Big Brook and Ram Brook Finds

Recommended Posts

Hi all,

I ventured to NJ to visit Big Brook and Ramanessin Brook last weekend (Cretaceous, monmouth group). I found quite a lot of shark teeth I still have to sort through, but I could use help ID'ing some other fossil finds.

 

 

Some comments on each

1. This looks a little like bone to me of some kind, but not sure.

2-5 look like plates or scutes. Not sure if turtle or croc. I realize 4 may be just a cool concretion, but I wanted to check.

6. This one is fascinating with a suture pattern of sorts that looks like it joins two pieces with the same finger like pattern as those prominences.

7. Looks like a small piece of something in matrix.

8. I think this might be a sawfish tooth but it would be my first one and I wanted to double check.

9. I think this is a large Enchodus tooth? It has only a single edge to it.

10. I think this is clearly a small ungulate tooth of some kind. Not clear if it's a fossil or an extant species. 

11. Another something in matrix. You can see a bumpy/rough surface to the fossil in the second two photos.

12, 13. The tooth on the right I think is Enchodus, but I'm not sure about the one on the left.

 

Thanks all!

Hi @Snaggletooth19

specimens 2,3 and 5 look like crocodile scutes to me, number 4 doesn't look to be a scute in my opinion however it is the right shape, but the top doesn't have the classic craters you'd expect. number 1 could be crocodile or turtle bone however I'm more unsure on this. At first glance 10 looked like a possible ray/fish tooth however the hollow nature of it leads me to agree that its a more modern ungulate tooth, I should always read the description before I make a decision!:duh2:

 

Don't take this as a formal identification however. there are many on this forum who know way more than me and could hopefully identify your other specimens. hope this helps:)

1. Degraded coal

2. Unidentifiable

3. Possible crocodilian osteoderm (it is incorrect to call these scutes)

4. Unidentifiable

5. Indeterminate bone fragment

6. Ammonite chamber steinkerns

7. Mesostylus (callianassid: ghost shrimp) arm in matrix

8. Ischyrhiza mira (sawfish) rostral denticle (sometimes called a "tooth")

9. Enchodus (fish) tooth

10. Modern rodent molar

11. Probably Hoploparia (lobster)

12. Possible Mesostylus claw dactyl (hard to tell from photo)

13. Enchodus (fish) tooth

 

Nice finds!

10 reminds me of a rabbit’s tooth.
