Bronzviking Posted December 4, 2018 Share Posted December 4, 2018 Hi everyone, I found this fossilized seashell in Tarpon, Florida on a fossilized shell trail. Original formation unknown. It looks almost complete and has great ornamentation and detail. It has 2 boreholes that penetrated just the surface of the shell. It is approximately 1 3/4" x 1 3/4". Can you ID it? Many thanks in advance. Link to comment Share on other sites More sharing options...
sixgill pete Posted December 4, 2018 Share Posted December 4, 2018 I am thinking some species of Chama. @MikeR 2 Bulldozers and dirt Bulldozers and dirt behind the trailer, my desert Them red clay piles are heaven on earth I get my rocks off, bulldozers and dirt Patterson Hood; Drive-By Truckers May 2016 May 2012 Aug 2013, May 2016, Apr 2020 Oct 2022 Link to comment Share on other sites More sharing options...
abyssunder Posted December 5, 2018 Share Posted December 5, 2018 I'm not a familiar with the bivalves of Florida, but somehow it looks close to Chama macerophylla. 3 " We are not separate and independent entities, but like links in a chain, and we could not by any means be what we are without those who went before us and showed us the way.

FossilDAWG Posted December 5, 2018 Share Posted December 5, 2018 Chama seems right. Rudists were around in the Cretaceous, and there is no Cretaceous exposed in Florida. Don 1 Link to comment Share on other sites More sharing options...
Bronzviking Posted December 5, 2018 Author Share Posted December 5, 2018 Chama macerophylla looks similar but I'm not convinced it is. I'm pretty familiar with Florida seashells and I've never seen this one before. (Extinct maybe?) The muscle scars, the umbo and hinge teeth should help ID this one if you know what to look for. Can you guys help please? @Plantguy @Shellseeker Link to comment Share on other sites More sharing options...

Plantguy Posted December 5, 2018 Share Posted December 5, 2018 That is a cool shell find especially with the borings! I unfortunately havent figured out my Chama collection yet--started down that path a couple months ago and didnt finish. Sounds like the gang above has it pegged as C. macerophylla which makes sense and seems to be fairly common in places down here. I'm hoping Mike can look and confirm and hoping he can also explain the differences between it and C. wilcoxii. I'm not smart enough to figure that out even when looking at the descriptions. At least in the collection I have there seems to be alot of variability and preservation. Here's a link to C.willcoxi http://neogeneatlas.net/species/chama-willcoxi/ Regards, Chris 2 Link to comment Share on other sites More sharing options...

Barby Posted December 5, 2018 Share Posted December 5, 2018 looks like a fossil oyster shell-- they are pretty common--don't know scientific name---many FL driveways feature them along with other crushed fossil shells... Link to comment Share on other sites More sharing options...

There are many varieties of Chama that look like a match, including wilcoxii. Mike thinks it is Chama emmonsi and he is the expert here. Link to comment Share on other sites More sharing options...

Still working on my Chama's....I do have a bunch of them but most are worn/broken. There seems to be one that has spines that has lines/small grooves and another without..I'll start a new thread if I ever get them sorted/photographed and put them up for ID.
