Megalodon fossil tooth baby shark blood stained real shark tooth Dino dinosaur

Ok I have owned this for 40 years I purchased this from the museum of science I.n Boston way back 40 years ago. It’s a real megalodon or shark tooth of that real this might be a baby tooth it’s big but not insanely big. It’s also blood stained red on the side of it. Probably broke when it bit into something like a ancient turtle. The fossil is not complete as it’s missing the side look at the pics of it. But it’s about 86-90% complete super rare to find the smaller ones !! Very cool and the blood stained don’t be pulling any Jurrasic park stuff Jeff goldblloom! Figured I’d put it up for sale!!!
