According to the seller, this is Hexagonaria from Manchester, Iowa. I can only find pictures of two of the ten Hexagonaria species H. percarinata (aka Petoskey stone) and H. mirabilis. It looks more like H. mirabilis than H percarinata, but the picture isn't great. My fossil also looks like Lithostrotionella and Acrocyathus floriformis. Any way to be sure what I have?

Fossil Coral from Tampa Bay Florida lapidary material
Gregcohen posted a topic in Member Collections
Many people are familiar with the lapidary material and cabochons from Indonesia. Not as many are familiar or aware of the material from Florida. In this case the Tampa Bay Florida area. These coral fossils are from 22-26 million ago and have been silicified. (The Florida Natural History Museum's invertabrate professor is co-authoring a paper that narrows the time period). The local lapidary club is open again so thought I'd share some of my amateur pieces and the raw material I've found.- 12 replies
