    Check out this shark tooth, It’s hollow all the way down to the tip!! What occurred to make this happen?? #fossil

    • @victor-perez has a better answer than me but this is a tooth that was just forming so you only get the enamel sheath. These are some of my favorite finds!

    • hmmm interesting. Thank you @Jeanette-pirlo

    • I am sure there are a few opinions on this and probably some controversy. In Mark Rentz’s Book Megalodon, Hunting the Hunter book, page 84, he writes about how teeth are replaced and states that the youngest teeth, which are the least developed and furthest back consist only of the enamel shell without a tooth base. I am no expert but his comments do make a bit of sense to me at least . ha ha. 🙂 If you have not read the book, I highly recommend. Its a great book and Mark Is a great guy too 🙂 PS there is also a picture of a tooth in the book that is very similar too

    • Makes more sense than what I was thinking, that some kind of worm drilled out the root of it. thank you.😊 @kelli-carpenter-2

    • Shark teeth are formed in a conveyor belt system. The enamel forms first and at first it is hollow and chalky. The enamel becomes more solid and the root begins forming starting with the middle. By the time it reaches the second replacement tooth position, it has full root lobes and is a solid tooth. The teeth rotate forward from below the gum, eventually emerging from the gum and pushing out the tooth in front of it. Each replacement tooth is a tiny bit larger than the tooth it is replacing in front of it (makes sense as the shark is growing larger). Although the rounded part of the tooth is usually more visually attractive (lingual side), the flat side of the tooth (labial side) faces outward.
