Gareth_ Posted December 19, 2021 Share Posted December 19, 2021 My smallest Megalodon tooth is a giant compared to some in this thread but it's still small enough to be worthy of a post here Link to comment Share on other sites More sharing options...
Meganeura Posted August 1, 2022 Share Posted August 1, 2022 Resurrecting this thread cause I wanted to share my own I found yesterday, at a slant height of 0.5” - and based on what I know about Megs and tooth position, was from close to the front of the mouth where the biggest teeth usually are (Though correct me if I’m wrong on that!) 1 Fossils?

Rock Hound Posted August 3, 2022 Share Posted August 3, 2022 I honestly opened this thread, thinking I'd post pics of a nice 3" Meg I just purchased. Clearly, by small you didn't mean 3" teeth. Some nice pics, are in this thread. 1 Link to comment Share on other sites More sharing options...

Really cool find!! I'd call that an upper jaw posterior tooth (right at the back) which is cooler than an anterior tooth as they're rarer 1 Link to comment Share on other sites More sharing options...

I always thought the posteriors were the curved ones - are those the lower posterior teeth? Fossils? I dig it. Link to comment Share on other sites More sharing options...

I always thought the posteriors were the curved ones - are those the lower posterior teeth? This is all based on the info I've gathered over the years, I may be wrong but it's the best I've got This is an oversimplification.... Upper jaw anterior - wide and tall crown, the serrated edges stay wide (as opposed to lower anterior) until they abruptly curve in to make the tip Upper jaw lateral - a noticeable hook in the crown, crown height reduces Upper jaw posterior - similar to the lateral but a very short crown height vs root width Lower jaw anterior - narrower than the upper anterior teeth, very tall crown with blades that are a straight line from the root to the tip - classic dagger shape Lower jaw lateral - crown with at the root stays wide, crown height shortens, about 1/3 the way up the crown the blades start to pinch in Lower jaw posterior - very wide root vs crown height, very pinched crown Lower jaw teeth are much more symmetrical too On your tooth, one blade is straight, one is curved - indicating it's upper jaw. The height of the crown vs the height of the root points to it being posterior (very deep root for the size of the crown) Some teeth just don't "fit" in the above description.... there are nuances as obviously reconstructed tooth sets is not an exact science for an extinct genus. I have a number of different theories as to why but that's another topic haha Just some examples I own or have owned... Upper jaw anterior - 125mm slant height Upper jaw lateral - 96mm slant height Upper jaw posterior - 43mm slant height Lower jaw anterior - 100mm slant height Lower jaw lateral (probably one of the first lateral teeth - the crown is starting to pinch in). 123mm slant height Lower jaw lateral - 114mm slant height, 96mm wide! One of the last lateral teeth If you're still reading this post.... sorry, I haven't had a lower jaw posterior (yet!) 1 Link to comment Share on other sites More sharing options...

One of the last lateral teeth If you're still reading this post.... sorry, I haven't had a lower jaw posterior (yet!) Thank you so much, this actually helped and explained a lot! Also I didn't even realize that my tooth had the slight curve on the right side of the blade until you pointed it out - it had looked straight to me - but I had been looking for a much more pronounced curve like the many other lower posteriors I have. They're all I've been finding lately! Edited August 5, 2022 by Meganeura 1 Fossils? I dig it. Link to comment Share on other sites More sharing options...
