Hi all! I recently purchased this dinosaur bone from an estate sale in Maryland USA. I think it looks like a vertebrae, but I’m not sure if I’m right. Does anyone know what it is, or even what it came from? It weighs 1.475lbs and was labeled from the Jurassic period (although the person that labeled it is a gemologist, not a geologist so it was his best guess after researching). The tape measurer pictured is in inches, I could not find one with centimeters. Thanks for any help!!!
