pefty Posted August 5, 2020 Share Posted August 5, 2020 Anyone seen this species or similar? Found in Pennsylvanian spoil piles of central Illinois (near Peoria). Is it part of some kind of alga? Not my find and not my specimen, so these photos are basically what we have to go on. More broadly, can anyone here recommend a Treatise-style taxonomic book detailing known algal heads / macroalgae in the fossil record? Thanks.

Petalodus12 Posted August 5, 2020 Share Posted August 5, 2020 Could it possibly be a sharks tooth? I’m not sure of the species but I do know that there were sharks that had teeth that looked similar to this (something like Deltoptychius). Just a thought.
