Vieira Posted January 4, 2017 Share Posted January 4, 2017 I found this tooth and I'm with some doubts in this identification. My guess goes to Chubutensis but i'am not certain.

My vote is for a chub, but I have seen teeth with a cusp like Yours that are called meg. Tony PS Age of formation may narrow it down. 1 Darwin said: " Man sprang from monkeys."

Al Dente Posted January 4, 2017 Share Posted January 4, 2017 The simple answer is to follow Cappetta. He has chubutensis occurring in the Early Miocene (Aquitanian and Burdigalian) so if your tooth is from the Burdigalian, you can call it a chubutensis. I think the reality is much more difficult. Some will say that Miocene megalodon teeth had cusps on the juvenile teeth and lost them as they become adults. In North Carolina we (amateur collectors) tend to call the cusped teeth that come from the Middle Miocene Pungo River Formation C. chubutensis. I think a lot of Maryland collectors call Middle Miocene teeth C. megalodon whether they have cusps or not. What adds to the confusion is lower teeth of chubutensis and angustidens frequently lack the side cusps so they look like C. megalodon. 8 Link to comment Share on other sites More sharing options...

Shellseeker Posted January 4, 2017 Share Posted January 4, 2017 Great!!! find -- I really love the color.. Reds and pinks are very attractive.. For your location, this must be a Chub, but in South Florida we do not have many/any Chubs but I have found these Megs with "regressive" traits. I am still seeking my 1st Chub, but I am pleased with C. Megalodon cusps.

sixgill pete Posted January 4, 2017 Share Posted January 4, 2017 Filipe, what a gorgeous tooth. The pinkish color of it is amazing. Do Not let my granddaughter see this tooth, she will want it for her pink bedroom. This is the second really, really nice mega shark tooth posted so far for 2017 ( see Ropterus's post ... At this rate, looks like 2017 will be a great year for fossiling. As far as I.D. personally due to the small cusps and age of the sediments, I would also call it C. chubutensis. 1 Bulldozers and dirt Bulldozers and dirt behind the trailer, my desert Them red clay piles are heaven on earth I get my rocks off, bulldozers and dirt Patterson Hood; Drive-By Truckers May 2016 May 2012 Aug 2013, May 2016, Apr 2020 Oct 2022 Link to comment Share on other sites More sharing options...
FossilDAWG Posted January 4, 2017 Share Posted January 4, 2017 My understanding is that the Carcharocles lineage is a series of chronospecies, which is to say that the lineage changed morphology gradually over time from conspicuously cusped forms to the end-point C. megalodon without cusps. In this sort of a lineage there is no abrupt jump from one morphology to the next, so distinctions will always have a certain degree of arbitrariness. On the other hand, in the more familiar pattern where species split into two lineages (shown as branching on a phylogenetic tree) the daughter species may evolve rapidly as they specialize on different niches, so distinct morphologies evolve quickly and you are less likely to find fossils with intermediate morphologies. Beautiful teeth, everybody. I also like the sound of "megalodoon", sounds Scottish. Don 2 Link to comment Share on other sites More sharing options...

Thank you Pete I'm very happy with this tooth. This is still not a finding of 2017. Only the preparation was in 2017 . I hope this year will bring me as good finds as last year.
