Venice Beach Florida unknowns

[JamieLynn]

Hello all! I had a nice little trip to Venice Florida (I posted about it in the Fossil Hunting Trip section if you want to see the "good finds"). Here are a few pieces that I am not sure about. Any help with ID would be appreciated!

I think these are turtle: 

A

 

B

 

C

 

I think these are alligator teeth:

D

 

I don't know if these are teeth or claws: 

E

 

other side: 

 

Not sure what the heck this is...it's ever so slightly curved:

F

 

Not sure what these long straight sections are. Possibly large stingray mouthplate broken sections? They are not like the stingray barbs I found- these are more straight and parallel lines. 

G

 

 

 

 

 

Not sure if this is the same as above but it is more curved:

H

 

 

Thanks for any help!

A. Agreed. Likely softshell turtle--the rippled texture on one side is distinctive.

 

B. Looks to possibly have bone texture but to worn to say more. (Common with beach finds tumbled in the surf.)

 

C. Difficult to see without having the specimen in hand if it is bone texture or simply phosphatic matrix.

 

D. The flatter on on the left seems the right size and shape for a barracuda teeth (you can find images on the forum with a search). The one on the right is very worn and likely past a positive ID but could be shark, fish or more unlikely gator.

 

E. Worn shark teeth with most of the root missing.

 

F. Definitely bone texture but likely too small to have enough distinguishing features to say more.

 

G. Top to bottom--the second and definitely fourth appear to be myliobatid tooth plates. The top and number three look to be worn stingray tail spines. The second down is difficult to make out in the photo. If it shows signs of symmetry and similar edges along the two long sites and a possible ridge down the middle then I'm in the tail spine camp. You'll notice that the fourth item at the bottom looks to have the characteristic ridged roots characteristic of a myliobatid tooth plate (as in H).

 

H. Myliobatid tooth plate--some are more straight and some are more curved. Do an internet image search for "myliobatis tooth plate" and you'll see how these strips tile together into a crushing plate.

 

 

Cheers.

Ahhh..was doing some research on Myliobatis and came across this possible ID for this little fragment.....I think it's Prisis - sawtooth shark?

It does have the look of a sawfish rostral "tooth".

 

 

Cheers.
