Ramanessin/Big Brook (New Jersey) Fossil Help

[Nanor]

I have been fossil hunting in the Monmouth County, NJ area for quite a few trips now, and I have accumulated a good amount of fossils I haven’t been able to ID. Here are some of them:

Note: feel free to ask for more angles; I didn’t want to post too many images.

1 inch for scale

Found in Ramanessin - no idea what it is

Found in both brooks - 5 in middle look to be same species; I believe far-right is pycnodont or hadrodus 

Left - found in Ramanessin; think its coral

Right - found in Big Brook; thought it was coral when I found it but I’m now leaning toward coprolite

Both from Ramanessin; Left seems to be an imprint from some sort of spine; My father thinks the one on the right is some sort of crinoid

Both found in Big Brook; Possible reptile teeth; maybe mosasaur or croc, though they are very small

Found in both brooks; left seems to be a possible Pachyrhizodus; all have distinct carinae 

Found in Ramanessin - potential hadrosaurus tooth fragment 

 

Thanks in advance for your help!

 First and 3rd look like Enchodus fangs. The others are saw-skate rostral "teeth" or denticles. Ischyriza mira

First is a Belemnite phragmacone. The others look like Enchodus to me.

This looks like a very water worn shrimp burrow.

Wow, thanks for the help. I had no idea belemnite phragmacones were even a thing. Glad I could learn something new today.
