ID Help with Big Brook and Ramanessin Brook Finds

[Snaggletooth19]

I ventured to the NJ brooks last weekend and made it to both Big Brook and Ramanessin Brook (Cretaceous, mix of Navesink and Mt. Laurel formations I believe). I found a few goblin and crow shark teeth, but need some help with ID for a few other finds. Thanks in advance for any help!

 

 

Here are some detailed images of each. #1: concretion, or tooth?

 

  

 

 

#2, definitely looks like a vertebra, but for a fish or shark?

 

 

 

#3 also looks like a vert, or is it another concretion?

 

 

 

#4: I found a few like this, but can't tell if it's just a weird concretion or some kind of plate or scute?  

 

    

 

 

#5 Looks like something in matrix

 

 

 

 

#6 looks like some kind of small reptile tooth to me. It's a little hard to tell, but it does have a worn enamel appearance and some worn ridges on two sides.

 

 

 

#7 of course is a pretty large shark tooth, but it's a bit worn and hard to tell from what genus/species. Looks a little like a goblin, but the base near the root is so wide.

 

 

 

#8 might just be a concretion, but it did have a terestrial animal tooth appearance to it

 

 

 

#9 looks like a tooth, but I can't place whether it's a fish or reptile?

 

 

   

 

 

#10 looks like part of a vertebra?

 

 

 

#11 looks like part of a plate or reptile shell?

 

 

 

And last #12, pycnodont? bone?

My best IDs:

 

2. shark vertebra

3. bony fish vertebra

4. concretion (or some other non-fossil thingy)

5. possibly fragments of crustacean?

7. goblin (Scapanorhynchus) lateral tooth

9. Enchodus fish tooth (worn)

10. bony fish vertebra (split down the middle)

 

Not sure on the others, better photos might be useful.  Hope this helps.

Here's my attempt:

1. Belemnite rostrum or guard
2. Shark vertebra
3. Fish vertebra
4. Concretion
5. No idea, but there does seem to be some texture that, together with the shape of the pieces, may indeed suggest crustacean
6. Another belemnite guard or rostrum?
7. Shark tooth
8. No idea
9. Worn Enchodus-tooth
10. Fish vertebra
11. Turtle plastron
12. No idea

Let's see what others make of this...
