Possible Turtle Shell from Summerville

Hey guys! New member here from Charleston. Hoping to get some help ID’ing what I think might be turtle shell pieces and another potential fossil. Found these in a creek in Summerville along with some teeth (Chandler Bridge Formation). Thanks!

Welcome to the Forum! :)
I agree with turtle for the first two, but I have no idea what would be the other one.

Welcome to the forum from Florida. Yes the first one is a nice tortoise shell and the smaller one is a turtle shell or scute. The unknown fossil could be a bivalve imprint on rock?

Welcome to the forum from Argentina.  :D

 

Yes, definitely the two are carapace or plastron fragments  af turtle. It is likely to belong to the now-extinct Psephophorus sp turtle genus (related to the modern-day leatherback turtle). This genus was quite common during the Oligocene, 30 million years ago in Summerville. Unfortunately I have no idea what the third fragment might be, but I do not rule out the possibility of being crocodilian or whale material worn out by the action of water...

Is It real, or it's not real, that's the question!

long piece could be like a c.p.5 and the smaller piece  like an edge piece, possibly like a 2 or maybe towards the back, like a 9, 10 in that area.

This is a good illustration of why I sometimes object to the use of the term "scute" when referring to the carapacial or plastral bones of reptiles.  The illustration makes the distinction, if you study it.  Notice how the scutes (the thin, keratinous [fingernail-like] plates overlap and cover the bones of the carapace.  Scutes are not bones, but cover bones in a pattern that does not conform to the pattern of the bones..

 

For example, in the diagram vertebral scute 2 (v.s.2) covers and overlaps neural bone 2 (n.2) and parts of neural bone 1 (n.1) and neural bone 3 (n.3) as well as parts of costal plates (bones) 1, 2, and 3.  Scutes and bones are not synonymous. 

 

While these bones are often preserved as fossils, the keratinous scutes are not preserved.  So, it is erroneous to refer to a fossil scute.

Nice turtle finds. Can we see some additional angles/views of this unknown? Thanks.

I suspect the turtle bones are Pleistocene and from freshwater or land turtles. A mixture of ages is common in stream finds. Can't make anything out of your last one though.

I agree.

More photos of the third one along with a photo of something similar I found in the same area. They might just be rocks, I’m a newbie :)

The radiating patterns might be crystal growths, maybe something similar to the ones of the "chrysanthemum stone".
