FossilDudeCO Posted January 26, 2017 Share Posted January 26, 2017 Hey everyone, I am looking for a decent Chubutensis tooth for a display and came across this one. Location is listed as South Carolina Size is listed as 4.09" Title is listed is Chubutensis I am just not so great with Shark teeth yet, can anyone confirm this to be a Chubutensis?

Darktooth Posted January 26, 2017 Share Posted January 26, 2017 I don't know if this would qualify as chub considering there is not well defined cusps. I see a little wavy portion near the root but I wouldn't consider that cusps. Maybe someone else could confirm or deny. I like Trilo-butts and I cannot lie.

Darktooth Posted January 26, 2017 Share Posted January 26, 2017 Maybe transitional? 1 I like Trilo-butts and I cannot lie. Link to comment Share on other sites More sharing options...

FossilDudeCO Posted January 26, 2017 Author Share Posted January 26, 2017 Thanks for the reply, I hadn't thought about transitional being an option! 6 minutes ago, darctooth said: Maybe transitional?

FossilDudeCO Posted January 26, 2017 Author Share Posted January 26, 2017 Thanks @Harry Pristis The "cusps" on this are nowhere near that nice! It may be harder than I thought to find a Chubutensis. Link to comment Share on other sites More sharing options...
Max-fossils Posted January 26, 2017 Share Posted January 26, 2017 Cool tooth! Honestly, if it weren't for the very slight curve, I would have immediately shouted meg! Sorry that I couldn't help; shark teeth are definitely not my strong point! Best regards, Max Max Derème "I feel an echo of the lightning each time I find a fossil.

Darktooth Posted January 26, 2017 Share Posted January 26, 2017 There is also the possibility that it is slightly pathological. I like Trilo-butts and I cannot lie. Link to comment Share on other sites More sharing options...
fossilselachian Posted January 26, 2017 Share Posted January 26, 2017 Could be a chubutensis but if you want one for a display, I'd wait for a tooth where the lateral cusplets are a little more well defined/developed. 1 Link to comment Share on other sites More sharing options...
FossilDudeCO Posted January 26, 2017 Author Share Posted January 26, 2017 Yes, I think I will hold off, this one seemed to be a decent price for the size and the condition though. I was just having issues differentiating. Glad you all could help! If the experts can't tell the difference than visitors coming in won't be able too! Thanks for all the feedback everyone.

sixgill pete Posted January 26, 2017 Share Posted January 26, 2017 4" would be huge for a C. chubutensis. Personally, the tooth look like and I would label it as a meg.

sixgill pete Posted January 26, 2017 Share Posted January 26, 2017 @FossilDudeCO Don't think I have ever seen a 5" chub. Also 4 1/2" would be a massive ric and angustidens. These sizes would be absolute maximum. A 4" ric, angy or chub is huge, at least in my experience. I have 2 rics that are just shy of 4", all my others are closer to 3 or under 3. My largest angustidens is right at 3" although I have seen one 4 1/8. I have never seen what I would call a true chub over about 3 1/2. Even the tooth in your illustration, labeled as a chub, I would call a meg. Here are some pics of one of my Lee Creek chubutensis.

sixgill pete Posted January 27, 2017 Share Posted January 27, 2017 I just want to add for everyone, that my Id's of megs and chubs is just my opinions and thoughts on individual teeth.

Brett Breakin' Rocks Posted January 27, 2017 Share Posted January 27, 2017 And just to add to what @sixgill pete said. The ones I've been stalking online are on the small side. This is one I finally went with. I posted it in my gallery. Identified as a Chub from SC just shy of 2". Link to comment Share on other sites More sharing options...
britishcanuk Posted January 27, 2017 Share Posted January 27, 2017 I sometimes like to remind myself that a species (as well as every other taxonomic level) is a construct that we created to help us understand relationships better, but in nature it isn't so cut and dry. It isn't as if one day all chubs became megs, it is a gradual process that took at least a couple millions years. This tooth has vestigial cusps and I think it would make a nice addition to a lineage display, slotted right between a typical chub and a typical meg. 3 Link to comment Share on other sites More sharing options...

As I mentioned @darctooth I hadn't considered a transitional tooth. My expertise lies in Green River Eocene fish so sometimes I forget this!
