caloosahatchee possible antler? & which scallop

[dalmayshun]

On my recent trip to the Caloosahatchee (while waiting for the Peace River to descend a bit) a friend and I went to our favorite place, as I recounted on my recent A DAY ON THE CALOOSAHATCHEE post under the Trips section of the forum. Besides the things I can identify, I found what I think is a piece of antler, though it doesn't look like a whitetail deer antler to me, so I hope someone might be able to help ID it. 

     I also found a small delicate scallop I was not able to ID . Over the years I found many kinds of scallops, i seem to recall seeing a similar one once in a post identifying Ft Thompson formation scallops, but can't locate that now. Any help in the little scallop would also be appreciated. And finally, we found 1 exceptional Vasum Horridum that i showed under my Trip post. The one posted here, had a few broken points, but still has cleaned up well and doesn't look as shabby as when I first found it. I these Vasum are spectacular, and the complete ones are extraordinary. (OOPS, THE VASUM IMAGES RAN PAST MY ALLOWED SPACE, SO i'LL GO BACK TO MY TRIP POST AND ADD THEM IN THERE)

Looks like an antler to me. How many pieces are there, though ? I'm confused. 

[dalmayshun]

the round one, with the bumps near the base is definitely whitetail deer...( 2 images, side and bottom to show its roundness) . the other one is flattened, just doesn't look like deer antler to me. It is the last four images, surface, undersurface, one side, then the other side. Hope that helps.

Some antlers have tines that branch near the shedding point. That may account for the almost web like spread of it.

@Harry Pristis Would probably know better.

What's the age there? The shell looks like aviculopectin.

[dalmayshun]

fairly recent, Pleistocene, or Pliocene...Tamiami Formation...though some Ft Thompson formation also in the general area.

It does doesnt it...not sure how that lineage worked out....are they only Paleozoic/Mesozoic?

I'm wondering if this maybe is Lindapecten muscosus? Am looking for the ribcount...

I agree with Rockwood, some antler portions -- even the base sometimes -- are out of round.

It's hard to tell for sure from the photo, but the third photo of the base of the antler looks to be slightly concave which would indicate that it had been shed.
