britishcanuk Posted December 14, 2016 Share Posted December 14, 2016 I picked up this small but well preserved mako tooth from the auction site yesterday. It caught my eye because of the small cusp-like features and what appear to be (very) rudimentary serration like waves along the edge by the cusps. It is from Chile, so the location would be right for a transitional tooth. When it arrives I'll post some shots under the microscope. I'd like to hear others thoughts on this tooth. The truth is, for $15, I don't mind if it is a transitional tooth or not, but serrations had to start somewhere edit: I added some zoomed in photos from the original auction, this site seemed to have stripped some of the detail out after publishing. 1 Link to comment Share on other sites More sharing options...
Darktooth Posted December 14, 2016 Share Posted December 14, 2016 Nice tooth! I recently posted a similar tooth in PRK's topic, " Best Photo". Check it out. It is the only mako that I have personally found with cusps like yours. Dave I like Trilo-butts and I cannot lie. Link to comment Share on other sites More sharing options...

It's always sweeter to find them yourself, but I'm ok with hunting the web for ones I really want. Link to comment Share on other sites More sharing options...
Northern Sharks Posted December 14, 2016 Share Posted December 14, 2016 I would be inclined to consider that as more of a slight pathology than the transitional to great white form (now known as Carcharodon hubbelli). Post additional pics once you receive it and we should know for sure.

I see Middle Miocene Carcharodon hastalis with weak lateral cusplets as well but you don't see consistently serrated teeth (weakly to fully serrated teeth until around the beginning of the Pliocene.

It is from Chile, so the location would be right for a transitional tooth. It really depends on what layer the tooth came from. It could have come from a Late Miocene layer which would not be old enough for a transitional tooth. There are Late Miocene and Early Pliocene teeth from Chile. Back in the 90's loads of teeth were available until the Chilean government outlawed the export of fossils. It appears most of the teeth came from the Early Pliocene but I've seen a decent amount of unserrated Carchaodon hastalis teeth too which indicates a Middle to Late Miocene age. 1 Link to comment Share on other sites More sharing options...

TNCollector Posted January 7, 2017 Share Posted January 7, 2017 The "cusps" appear to be too symmetrical to be a pathology. I would say they are legit. Link to comment Share on other sites More sharing options...
sixgill pete Posted January 7, 2017 Share Posted January 7, 2017 Here are three what I have considered "transitional" mako's. They are from the Netherlands according to the info I received with them. The shoulders on one of them are very similar to this tooth. However there are visible serrations on all of these.

britishcanuk Posted January 8, 2017 Author Share Posted January 8, 2017 Sixgill, those teeth a fantastic. I would agree that your teeth are more "transitional" than mine. However those faint wavey serrations had to start somewhere. Link to comment Share on other sites More sharing options...

The point I was trying to make is that yours, at least to me seems to be an earlier stage transitional tooth. very nice tooth. 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...
