Suchomimus tooth

[carch_23]

Hi guys, just stumbled on these teeth from a fossil shop’s website. Never bought from them so not sure on their reliability/ reputation for ID-ing teeth. Im not really familiar with Sucho teeth either. Was wondering if you guys can help me out however, the website only provides this side of the teeth so I emailed them asking if they can provide more. But at the moment, just this unfortunately. 

 

Location also says Gadoufaoua, Niger. 

 

Thanks in advance!

To confirm Suchomimus you would need closeup pictures to see if serrations are present. The first one appears to show a carina that could exhibit this feature, but based on the current photos it is impossible to tell. The second one looks more like a croc tooth to me but better, closer pictures could suggest otherwise.

Even the most trusted sellers can fall victim to misidentification, so it’s always good to confirm an ID based on your own knowledge/research.

Thanks for that. Yep I agree. Although I believe I can distinguish between croc and spino myself, though because I very rarely see sucho teeth for sale, I havent seen enough to have the knowledge or experience to ID between croc or sucho. Will update with more photos if they do get back to me. Thanks again

Would need closer photos but it is hard to tell with the angles.  Have a photo of the cross-section?  Suchomimus teeth can sometimes have an oval cross-section.

Like its been said a diagnostic feature of a Suchomimus tooth is dentulation on its Carinae.  So without a very close view of that area it may be difficult to make a definitive call.  They are not your typical serration and should look like this.

@Troodon Hi Frank . What if the carinae is worn or simply don't preserve small serration ? , Is there others way to tell the different between  croc and suchominus tooth ??

 

thank you in advance

they havent returned back to me yet but hopefully they do give me serration and cross section images of the teeth. will post when they do. Thanks.

Hi Troodon, thanks for that. I did see your post from previous inquiries on sucho ID and saw this as well. Though was wondering if there were any other ways to ID sucho teeth based on the photos I have at the moment. Just making sure as sucho isnt really my specialty lol.

 

By the way, if serrarions arent in the best condition/ not as visible (hopefully it is), would you suggest passing on it? Thanks 

[Troodon]

If you want it to be definitive in an ID you should not buy one without that feature, its diagnostic.  The higher the quality of any isolated theropod tooth will result in a much better chance to ID it accurately.    Some croc teeth are more distinctive than others which mimic Suchomimus teeth so it depends on how it looks.

 

Features documented in papers:

Small marginal dentulation 

Textured, granular enamel

Subcylindrical in shape (conical)

Longitudinal fluting and or faceting

First one is a croc tooth looks to have similar preservation to gadoufaua, second crocodile again could be from either Jurassic or Cretaceous.

 

At this point I'm starting to think half of them know they are selling croc teeth and the other half have no idea what they are selling this is very sad.

Actually, I think I've observed certain vendors change their ID for these types of teeth from consistently Suchomimus to just plain crocodilian (not that I've followed these developments, but I believe certain sellers have even switched to providing a likely crocodilian identity for their teeth). Still, in my experience it's not uncommon for fossil dealers to provide incorrect identification for teeth: I've seen it with all manner of marine reptile teeth, whether from Morocco, the UK, Russia, USA or elsewhere (most persistent if which seems to be identification of Globidens phosphaticus from Morocco as Igdamanosaurus aegypticus and Russian platypterygiine teeth as pliosaur). Its just very specialist knowledge to properly identify teeth, in my opinion. But to knowingly provide, or continue to provide false IDs indeed is something else entirely...

Hi guys. Seller just contacted me again. These were the photos I was provided with. Ill ask for more detailed ones if need be. The longer, black one seems to have the texture I find with sucho teeth but I dont know for sure? They say the teeth dont have much serration but these were their three best. Thanks so much!
