Assorted marine critters

Recommended Posts

BuddingPaleo

Good morning, all. Here's a few I've been working on today. Found in sw florida, I think I'm in part of the Tamiami formation. Anyway, I think the little snail is possibly Nassarivus Quadredentatus, but not sure. The large grey I think might be Nodipecten, also not positive. The ones that look like little elephant feet I'm pretty sure are a type of coral, but I can't find a match so I could be wrong. The little "toothed" thing I'm thinking is a steinkern, but would like to know for sure, and from what type of critter. Is the button a sponge? And then there's the wormy looking thing, or shell rim? There are 6 objects shown,  shots with multiple angles are grouped together. Any help would totally be appreciated! 20180730_102349.jpg.262d7333726cd8f01fcdc2701c57e1d1.jpg

Your elephant feet are the internal cast of a barnacle. The sediment inside lithified and the shell dissolved away.

Well, that was unexpected! Thanks for that! :D

No wonder I couldn't find it while searching sponges and echinoids! You're a wealth today, thanks so much!

Fascinating, @Al Dente! I had never heard of this. I just googled it. I had no idea they produced gastroliths such as these - also didn't know there stomach was in their head. :faint:Next dead crayfish I see is coming home for dissection. ;)

Lori, they eat the dang things here in Louisiana by the bushel basket.  Where can I send you a couple of hundred pounds? :D

When I was down working the Katrina cleanup, I went to a crayfish/crawfish boil. They were good, but I refused to suck the head. Who knew it was a good source of calcium? :D

It is a good source of calcium, but is it worth eating stomach goo? I wouldn't have either! Lol

As for me, I refuse to eat bait. (and I'm allergic to shellfish, so I suppose it is moot)

This round object is from a crayfish. They have two round calcium carbonate objects in their heads. I've attached an image from the internet showing these structures in the crayfish.

Interesting Eric. I have a very similar item I found recently at a river site here in NC. I was thinking bryzoan, but now I'm wondering.

The second shell I thought Pecten as soon as I saw it because of it's striations

The last one looks like horn coral but I'm not sure it's found in your formation. You would have to research that.

The toothy one is very unusual but I think it might be coral. Can you photograph the ends?

Here ya go. Please excuse my ugly fingers. Lol I had been thinking internal spiraled shell structure, not coral. Interesting. I'll look into the horn coral. Thanks!

Looks like a core to an archimedes screw bryozoan.

The coiled structure is the center of a coiled gastropod and not an Archimedes bryozoan or horn coral both of which are long extinct (Paleozoic).

Should have looked at the location.:blush:

Not sure, but I'll throw this out: calcareous tube of a serpulid polychaete?

@ynot

Found new info on your screw-shaped. I got another book from the library "A guide for identifying fossil shells and corals, by Brayfield". It led me to Bryozoans of Florida and than I found this illustration which looks just like yours! It's a Bryozoan archimedes; what ynot originally said, but others said it was extinct..... but it sure looks like it. Compare and discuss.

I thought the same thing. (Searching bryozoan fossils for another find.) So now I'm confused again. Lol paleontology-ing is hard, step aside adulting, there's a new hard in town. :hearty-laugh:

Archimedes is, as far as I know, restricted to the Mississippian and Pennsylvanian periods, and there are no exposures of these rocks in Florida.  What is the name and other details of your source on "bryozoans of Florida"?
