Anyone know what this tooth could be?

Maybe some folks local to the area or who have been there will weigh in?

Crocodiles Thalatosuchia connus aux Vaches Noires

 

Classe Sauropside Sous-Classe Diapside Super-Ordre Crocodylomorpha Sous-Ordre Thalatosuchia Clade Crocodyliformes Famille Metriorhynchidae Genre Metriorhynchus

 

Ce groupe de crocodile à la particularité de s'être totalement affranchi du milieu terrestre, devant totalement pélagique, c'est à dire vivant en haute mer. A l'heure actuelle nous n'avons pas de certitude sur leur mode de reproduction qui est encore très probablement inféodé au milieu terrestre, besoin de pondre sur terre pour faire éclore les progénitures. Plusieurs espèces sont connues sur le site des Vaches Noires, par divers ossements, crânes complet étudié et décrit par Sylvie Wenz dans les années 1960.

Gorgeous. These are some great finds. I have yet to see gator teeth like that.

Hey , you make me jealous ,  I was there before this summer  , but did not have such luck ( although I did not count myself unfortunate ) !

So even though croc is the obvious candidate , I feel the size (4? 5 ?cm) and shape may point towards bigger marine reptile .  Any section pic of the loose tooth ? . Were does the first one ( loose one ) comes from exactly on the site ? form the Marnes de Dives ? the second tooth (?) seems to be coming from the oxfordian , what's the size ?

Hi! Yes it was the first time I found a tooth so I was very excited. It was  kind of high up in the argile/clay?   that is is on the beach maybe 300 meters from the end of the beachwalk at Villiers sur mer...can’t really explain better since I’m still new to this. It was sitting in the clay with the upper part facing out thinking it was a Fossilised piece of wood I pulled it out but it was better!! Its big maybe 5-6 cm ( the loose one )and the one attached is even bigger 8-9 cm but I feel it might be a claw? It was found low in the clay/sandstone maybe 100 meters from the end of the beachwalk.

 

hope this helps

Thank you! Yes it’s very exciting not sure it’s a crocodile tooth yet though. Hope the experts here will help since I’m a rookie

Thanks! Appreciate it, mine is like 5-6 cm though could it still be?

I'm also thinking croc tooth. They can be large. Just to be sure, can you post pictures from different angles and the bottom? If you are still at Villers sur mer, try to visit the local museum.

Beautiful find! 

[LeviBess]

Here are some of the stuff I found during the 2 afternoons I spent at the beach of faisais des vaches noires, Villiers sur mer in France this week.

 

I think I have an idea of most of them by now but feel free to ID anyway ! And yes I know some of them are minerals but I think they are beautiful so I put them here as well. Wondering about this piece of bone(?) though, that’s posted in different angles.

Ok , so not in place in the Marnes de  Dives on the beach  but on the stuff that builds up  the pre cliff ( eroded / flowing down from the cliff ). No Callovian stuff, but oxfordian .. .as the other tooth /stuff encasing rocks shows . I will have a look in my documentation . BTW, I don`t think 34 is bone material , more probably some shell stuff. Thta' s what I love in Villers , never know what will come out . Your mix of find is rather standard , but 31 and 32 are outstanding .What is the section of 32 ? from the pics it looks like pretty much circular rather than sligthly flattened

Thanks for your answer! No maybe I explained weird.both 31 and 32 was found in the clay that’s in direct connection with the beach, just kind of high up in it and 31 was just a fallen « rock » from higher up that I found in a bunch of fallen rocks. 

Is that more clear? 

[taj]

Sure ! So 31 is oxfordian , and I don't have any idea about it , maybe a little bit of prep ? and 32 is callovian , so you have the choice between 3 croc species and several marine reptiles . As for the croc, metriorhyncus would be a good candidate , if the section is not too circular (i.e a tad flattened)

wow thank you for all that info, do you have any suggestion on how to prep fossils in this kind of matrix? 

Im scared to destroy it. 

[taj]

Well, if you do not have access to heavy stuff ( pneumatic stylus and air abraser), il would recommend scalpel, mounted needles, very small chisel with hammer and a touch of HCL from time to time ( not directly on the fossil). Soaking the rock in water for a few days before beginning cannot harm and perhaps make things a little bit more easy. And again congratulations! ( let’s attribute this to beginner’s luck you won’t fetch such nice tooth every time)
