Hi all, it's me again!

for my first expedition of the year, I decided to go to big brook to try my hand collecting there. had quite the adventure, found some neat things. but there are a handful of oddity's that I am unsure. in my research that ive done over the day I have a couple ideas, but any confirmation from experts is always appreciated. 

 

first one up is this weird thing. I'm not sure what this is although it's no concretion

these ones are also strange, but I have some ideas on a few of them. top two are probably vertebrae fragments, but I have no clue what they are from.  bottom left is a total mystery, but I think that the shark tooth in the right is possibly a Hybodont tooth. I say this because of all the research I've done both on this forum and the Big brook website. it is the only one that matches the profile.

@The Jersey Devil @Rockwood any ideas?

First picture appears to be a ray tooth. Instead of a vertebrae I'd guess gastropod portion for the top one in picture 2. The tooth on the right doesn't look like hybodont; I think it's just a worn crown from a different shark.

It is pretty easy to crop photos on a phone - small items like these are better if you crop out a lot of the surrounding background.

It makes for better pictures for ID.  There are also websites and other apps for photo editing.

Upper right looks like part of a gastropod steinkern.

Any chance the first one, the ray tooth, was stuck in the screen from a previous Maryland or Virginia trip? Looks too long and skinny to be a Brachyrhizodus tooth. Maybe I just haven't seen a long skinny version.

Not totally sure it is a ray tooth.

 

Cropped, brightened, and combined:

I agree. This is a typical Tertiary-type myliobatid tooth and unlike the Cretaceous ray teeth one would expect to find at Big Brook. Sadly, it is not uncommon to find teeth from other time periods brought there by careless fossil collectors. Some may have fallen in accidentally having been collected from elsewhere but I have heard too many stories of people "seeding" the brook with teeth to make sure their kids would find something. A very irresponsible act. And with the unsustainable amount of collecting going on in many of these spots, I fear it will just become more common.

Your tooth is too smooth to be a hybodont. The labial side is too flattened for a hybodont. There's enough of a root left on your tooth to suggest a non-hybodont root shape (at least as far as typical Cretaceous Hybodonts go).
