Possible Hybodont tooth


DE&i

Recommended Posts

I'm sure this tooth is from the Hybodont Asteracanthus genus but unsure as to the species. The root is missing but would appear to be whole. I'm also not familiar with its shape. Its mid Jurassic and from the Bathonian stage. 

 

Any suggestions please @siteseer@Fossildude19

That’s a beauty! Sorry I can’t help with an ID.

Hey Darren, 

Nice specimen. I can't help out here too much. 

But I did come across this paper - not sure if you've seen it or not.

Hope it helps.

I can add that Leuzinger described the new species A.udulfensis in 2017(Reuchenette,Switzerland)

Admittedly a difficult view of a single isolated tooth. Would anyone recognise which tooth it could be from the Hybodont dentition.

Great find and gorgeous tooth! It looks like A. tenuis.

Hi @Archiethat's my thinking as well and perhaps could be. I contacted Dr Charlie Underwood a UK mezsoic shark expert. Who suggested we shouldn't rule out A. medius as well. I'd really like to know what row and position the tooth would have been placed Into the Hybodonts dentition.

I was wondering as well actually if it could perhaps be A. ornatissimus with that lovely ornamentation, was this ruled out? There have been several complete dentitions of various species of Asteracanthus found so you could try comparing with some of those for a fit for placement in the dentition.

Hi @ArchieI don't think  A. ornatissimus is present at this particular site. I'll have to double check. Would you know where I can aquire some comparative dentition images. 

 

Edit : Just heard back from Dr Underwood and apparently A. ornatissimus is present. But no positive I.D.s for this find.

Hi sorry for the late reply! I found a few images of dentitions on google images and from these it looks like your tooth may either be an anterior or posterior perhaps? Looking at it again A. ornatissimus seems a better match than A. tenuis.
