4 years, 7 months ago4 years, 7 months agoHi, @jon-moore – is Toxasteridae the family or is there some disagreement about that? I know some of the higher taxonomy can be a bit complicated.

4 years, 10 months ago4 years, 10 months agoHi @jon-moore, I’m going to tag several people who work with Florida fossils in case they have any ideas on what this is! @jeanette-pirlo, @vperez, @smoran, @rnarducci, @charlie-smith@cindy-lockner, any ideas on this fossil? Thanks!
Hi Jen, I’m not sure about the higher taxonomy. Toxasteridae does seem to be the commonly used family for this genus, but at least one document said that family is paraphyletic. I didn’t photograph the oral side, because it was not completely cleaned of matrix, but I can try to clean the specimen and then take a pic.
Ah, yes, the common issue in fossils – figuring out what is paraphyletic or not. A never ending problem across all of life!
