Gregory Kruse Posted January 21, 2021 Share Posted January 21, 2021 I found these near Cape Coral in a stock pile of sediment that was going to be used for landscaping. Are they Arcinella cornuta, the spiny jewel box clam? See link here: https://neogeneatlas.net/species/arcinella-cornuta/. Thank you! Link to comment Share on other sites More sharing options...
hemipristis Posted January 21, 2021 Share Posted January 21, 2021 They look like the Arcinella cornuta specimens I have from both NC & FL. 'Those who cannot remember the past are condemned to repeat it.' George Santayana Link to comment Share on other sites More sharing options...
Coco Posted January 21, 2021 Share Posted January 21, 2021 I can’t help you, but aren’t there more species with this one ?

MikeR Posted January 21, 2021 Share Posted January 21, 2021 3 hours ago, Coco said: I can’t help you, but aren’t there more species with this one ? Coco Yep. Arcinella cornuta. Abundantly found as both a fossil and recent in waters of the Southeastern USA. Coco, a near identical species is found in the Caribbean Arcinella arcinella. WoRMS list both as valid, although I am hard pressed to tell the two apart in pictures. Below is Upper Pliocene Arcinella cornuta from the Pinecrest Sand near Sarasota, Florida.

Gregory Kruse Posted January 21, 2021 Author Share Posted January 21, 2021 Thanks all! Thanks for sharing the Arcinella from the Pinecrest beds! Link to comment Share on other sites More sharing options...
Coco Posted January 21, 2021 Share Posted January 21, 2021 Thanks @MikeR Nice shell. I wanted to say : are there not more species with this shell, for example ovulidae, olividae, arcidae, muricidae etc... And not "several species of Arcinella" (I don't know enough the shells to be able to ask this kind of question). Next time I’ll try to be more specific.
