petrified dinosaur tooth?

[hlayne]

I recently acquired some of my grandfathers belongings and found this amongst them. my grandparents have lived in Montana, Idaho, and California. If it helps my grandfathers occupation was a miner. can you please help me id this? please and thank you. Also it measures at 6 1/2" long. and the tooth is flat.

Sorry. There may be small fossils in it, but this is just sedimentary rock. The darker layer is slightly more resistant to erosion. Tooth like shapes often form this way.

Not a tooth. There is no enamel present, no root structure or texture, ... and no real tooth morphology.

Agree with @Rockwood

very interesting piece though, and worthy of a conversation piece
