BLT Posted July 25, 2018 Share Posted July 25, 2018 I’m hoping someone will tell me which type of fossil I have? I think it is interesting because such a narrow piece is intact. It is from my yard in middle Tennessee. Link to comment Share on other sites More sharing options...
Fossildude19 Posted July 25, 2018 Share Posted July 25, 2018 Looks like an orthocone cephalopod to me. Nice one, too.

Jacob L Posted July 25, 2018 Share Posted July 25, 2018 I believe this is an "Orthoceras" Orthoceras ("straight horn") is a genus of extinct nautiloid cephalopod. This genus is sometimes called Orthoceratites. Note it is sometimes misspelled as Orthocera, Orthocerus or Orthoceros (Sweet 1964:K222). Orthoceras fossils are common and have a global distribution, occurring in any marine rock, especially limestones. These are slender, elongate shells with the middle of the body chamber transversely constricted, and a subcentral orthochoanitic siphuncle. The surface is ornamented by a network of fine lirae 1 Jacob "God creates dinosaurs, God destroys dinosaurs. God creates Man, Man destroys god.

Orthoceras became kind of a taxonomic dumping ground for Orthoconic cephalopods for a while. Being from Tennessee, this is likely some other genus and species. Maybe some sort of Michelinoceras sp. ? But not Orthoceras. 3 Tim - VETERAN SHALE SPLITTER VFOTM --- APRIL - 2015 __________________________________________________ "In every walk with nature one receives far more than he seeks."

Jacob L Posted July 25, 2018 Share Posted July 25, 2018 @Fossildude19 I think you might have been right with the Michelionceras. I found this picture of a possible Treptoceras out of our gallery It looks a little the same in my eyes. Jacob "God creates dinosaurs, God destroys dinosaurs. God creates Man, Man destroys god.

And, this was found in Tennessee, so it could be an Orthoceras? since Tennessee isn't in Sweden or the Baltic States... or am I missing something?

From Tim's link.... Orthoceras was formerly thought to have had a worldwide distribution due to the genus' use as a wastebasket taxon for numerous species of conical-shelled nautiloids throughout the Paleozoic and Triassic. Now, Orthoceras sensu stricto refers to O. regulare, of Ordovician-aged Baltic Sea limestones of Sweden and neighboring areas.[1] So "Orthoceras" can not be found in Tennessee. I think You are confusing "Orthoceras" and Orthocone. 2 Darwin said: " Man sprang from monkeys." Will Rogers said: " Some of them didn't spring far enough."
