Whatisit Marine fossil

Last Thursday, found a bunch of reef type fossils in the Peace River...  Sort while watching the NFL today.

Here are a few of the smaller items:

A ray denticle, a tapir cap, cypress wood,  and ....

Looks like the mold of a partial echinoid created by an encrusting tube worm.

Agree John that it very likely is a mold that includes a tube worm. The patterns on the Echinoid or sand dollar seems relatively unusual. It seems like the valleys between the ridges have intersecting "teeth".

I have found numerous echinoids and sand dollars that do not have matching sections.  I am wondering if anyone can identify any matching echinoids that would exist in SW Florida and with that identification possibly date the layer it came from.

Hey @Shellseeker could it potentially be a partial remains of specifically a starfish ? .. I'm assuming they are rare in Florida. 

(which I realized now are Echinoderms so related to echinoids) *oof*

I actually do not know if they are rare in the Florida fossil record.  I see plenty of modern starfish, but it never occurred to me that they would fossilize. Certainly this is the 1st time I can recall both finding and identifying a fossil starfish!!   :tiphat:

Sorry for the confusion , John. I just was not clear on which part of the fossil had grabbed my attention.

 

So , let me now try to find a little more about fossil starfish.... @MikeR

I know little about starfish as I have seen so few of them.  Roger will most definitely want it.

The Sun Star was the only one I could find readily from Florida when I ran my initial search.  I've personally never seen anything like it while trolling the internet on Florida fossils.

Instead of tube worms surrounding the starfish, I think these are casts of Cliona (boring sponge). I also think the starfish is an internal cast. The photo Brett shared is a cut open starfish. I think a cast of the cut open starfish in the photo would be a good match. Very neat fossil.

Ditto, Sometimes I find the expected. The best times are when I find something that I can not identify.  :fistbump:
