Bronzviking Posted August 4, 2018 Share Posted August 4, 2018 Hi Fossil and rock hounds, I found this strange looking piece when looking through my shark teeth. Found it on Manasota Key beach, Florida. I thought it was some vertebrae bone but than I saw 2 barnacles in what might be a grouping of shells. It also has pockets of limestone and small black bones or rocks cemented in some of the pockets and has some weight to it. It is about 2x2". Posted 5 photos of different angles. Has anybody ever seen anything like this? What is it? Thanks All. Link to comment Share on other sites More sharing options...

jcbshark Posted August 5, 2018 Share Posted August 5, 2018 I’m with Eric, the rest have eroded away Every once in a great while it's not just a big rock down there! Link to comment Share on other sites More sharing options...

Bronzviking Posted August 5, 2018 Author Share Posted August 5, 2018 I see the 2 barnacles but what is the rest of the structure? Link to comment Share on other sites More sharing options...

Plax Posted August 6, 2018 Share Posted August 6, 2018 you have to imagine broken barnacles and a fairly complete one within the broken ones. The black bits are phosphatic elements usually concentrated in lag deposits. Shark teeth are also concentrated in these lag deposits. Link to comment Share on other sites More sharing options...
lawooten Posted August 6, 2018 Share Posted August 6, 2018 Have you ever seen a coral reef? For the most part barnacles made up a reef in part. The other structures you are seeing are spaces that used to have barnacles but died or wore away through fossilization and erosion.

Bronzviking Posted August 6, 2018 Author Share Posted August 6, 2018 So what your saying is this was just a vehicle for the barnacles to attach too? Is this considered a fossil? Thanks for all the feedback! Link to comment Share on other sites More sharing options...

Plantguy Posted August 7, 2018 Share Posted August 7, 2018 Yep, you've got basically the core left. congrats they are interesting little forms. every once in awhile you'll find an unbroken grouping. The lower portions of the plates seem to hold up better as they are a bit thicker than the upper surfaces and are usually the last remnants when getting rolled over or around and tumbled. Thanks for showing us. Regards, Chris 2 Link to comment Share on other sites More sharing options...
