Orion1958 Posted August 6, 2018 Share Posted August 6, 2018 I would appreciate any help in identifying this fossil. My father purchased it somewhere in the Western US during the 1960's or earlier, but unfortunately I do not have any provenance. It sat in a display case until my parents passed away a few years ago. Due to space limitations, these are low-res pictures, but i'm willing to take different perspectives/resolutions as needed. My apologies for the poor tags... I truly appreciate the help!

ynot Posted August 6, 2018 Share Posted August 6, 2018 Welcome to TFF! The darker part is a weathered orthocone nautiloid, the lighter part is limestone. 2 Darwin said: " Man sprang from monkeys."

LordTrilobite Posted August 6, 2018 Share Posted August 6, 2018 I agree, that's a type of orthocone. No dinosaur fossil here. Olof Moleman AKA Lord Trilobite Link to comment Share on other sites More sharing options...
Fossildude19 Posted August 6, 2018 Share Posted August 6, 2018 Welcome to the Forum. I agree with orthocone cephalopod. The part that looks like a backbone is actually the siphuncle. The bottom part looks like a septarian nodule/concretion. No dinosaurs there. 2 Tim - VETERAN SHALE SPLITTER VFOTM --- APRIL - 2015 __________________________________________________ "In every walk with nature one receives far more than he seeks."

Orion1958 Posted August 7, 2018 Author Share Posted August 7, 2018 Thank you all for the quick, detailed responses! It's good to put an almost lifelong mystery behind me. I stand corrected about my "dino" fossil. Best, Scott Link to comment Share on other sites More sharing options...
