horse tooth, I think, but you need to photo the chewing surface as well as the side view

you save the best for last. Nice lower C. angusteidens tooth. good job on that one

need a photo of the chewing surface

These are shark vertebral disks

probably more turtle shell- not sure the type

soft shell turtle, nice example

my guess- turtle

this looks to be a nice section of dugong rib and that is likely what the two specimens prior to this are as well

this is a worn whale bulla

need to include a side view photo. Possibly more steinkerns (small clam casts)

Horse tooth (likely). Include a photo of the masticatory surface.

try to include several views of unidentified specimens. This looks like it may be a piece of vertebrae, but more views are necessary.

photo lacks definition to tell what it is. From the thumbnail I thought it might be a gar tooth or small crock tooth, but enlarged I can’t distinguish enough to suggest much.

Both of these look like trace fossils called steinkerns bivalve castings.

Nice teeth Susan, and very nice to have both an upper and lower. Finding it on Isle of Palms, it is likely transported down the Cooper, or washed up from off shore. I would guess the age could range anywhere from maybe 4 Ma. through Pleistocene.

Nice find Tina. I believe you have a portion a mammoth tooth.
