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!!! :)

Its a cetacean vertebra (whale) not dinosaurian.  Miocene/Pliocene age.  Good chance east coast find.    Calvert Cliffs MD,  Lee Creek Phosphate Mine, NC type of localities.

Agree. Whale, not dinosaur.

Do you think it’s old and fossilized? Or is it from one of today’s whales?

Yup what they said.

Do you think it’s old? Or is it from a recent whale?

It’s a fossil, to make sure you could do the burn test where you burn it, and if it smells like burnt hair it’s modern, and if it doesn’t, it’s a fossil.

Preservation  is typical of others I've found at Lee Creek and Calvert so its like I said Mio/Plio in age
