Shark teeth, fish vertebra, and other fossil finds from Big Brook NJ

[fossils_rock]

Had the chance to return to Big Brook, NJ with the family to search for cretaceous-era fossils. I am new to fossil hunting (this was my second time!) and had some interesting finds this trip - it is so much fun to learn about the prehistoric life in this area. It was a lovely day, although the brook was a little on the cold side. I would appreciate some help with identifying these 9 fossils:

My best guesses are:
1) Mackerel/porbeagle shark (Cretolamna appendiculata)
2) Fish vertebra (is it possible to figure out the species?)

3) Unsure about this one, also Cretolamna?

4) Brachiopod (Choristothyris plicata)

5) Salmonoid (Enchodus petrosus)

6) Mackerel/porbeagle shark (Cretolamna appendiculata)

7) Goblin shark (Scapanorhynchus texanus?)

8) Sand tiger shark (Carcharias)

9) Crow shark (Squalicorax kaupi)

Happy to provide more pictures if it would be helpful.

 

Also, I found what looked like a bone (in the center of the below picture), but ended up throwing it back in the brook, believing it to be a concretion. Can anyone confirm that it's probably a concretion? Just want to make sure I didn't discard something like a Dryptosaurus phalanx in my search for shark teeth!

That is definitely a concretion in the center of the screen.

Most of your IDs are correct. Some of the shark teeth cannot be identified because they are too worn.

 Nice fossils. I see some other fossils on your screen.  Looks like maybe a  tiny enchodus jaw, Pycnodont tooth, enchodus fang and belemnites as well. Good job!
