How rare are real plesiosaurus jaws on the market ?

[Brevicollis]

Hello, I wanted to ask how rare are Plesiosaurus jaws on the market?

I've seen hundreds of real, fake, and composite Mosasaurus jaws from Morocco, but now I've seen a nice, big and real Plesiosaurus jaw with two teeth and no evidence of plaster. How rare is it to find a good one on the market? 

 

Thanks !

Yep, even hemi-jaws are only found about twice a year, I've been told. So getting access to a well-preserved and non-composite one is really rare.

Never seen even Moroccan one.

And in most other location, even teeth are scarce.

Incredibly rare. If I were you, I wouldn’t pass up this opportunity. Remember, if it is in person, use a poker face, they may not know the rarity.(Friendly advice.) Good luck if you do plan to get it.

[Brevicollis]

Thanks for all your answers ! I'll try to get it.

I didnt got it. The price was OK at first, but in the last two minutes, 12 new bids came in and the price went from "nice and cheap" very fast to "too insanely expensive". Well, i'll have to find something else instead. Or i'll just save my money instead of spending all of it on one thing.

Are Eramisaurus teeth Common or are they some of the more rare Mosasaurus teeth ? Just wanted to ask.

[North]

Eremiasaurus teeth are quite common.

But id might be difficult, expecially with smaller teeth.

Sorry to hear that.

Turns out, the Easter Bunny (my father) got it and gifted me it ! 

Now I have a Plesiosaurus jaw with 3 and 2/4 teeth in it, and I'm really happy.

A real, not composed, plesio jaw, whith no evidence of plaster, and some nice teeth.

@M3gal0don_M4n, look !

 

I like that you can see the inner construction and the teeth/roots and bone structure. 

Its about 20 cm in length.

In 3th picture. Does it have carinae?

[Brevicollis]

@North Yes, it has !

Is this a good or a bad sign ?

I was wondering about that too, but mosa teeth are not that long, and dont have a root that is long and thin, and curved i think ? Some of the Plesiosaurus teeth i found online show a similar Not toothed carina too. Can you maybe identify the species ? Or can @pachy-pleuro-whatnot-odon confirm that its really not mosa ?

I will say him that. But Xmas was also great for my collection. I got a 5 cm Sucho tooth, and a big Pholidophorus bechei.

As far I know, plesiosaur teeth lack carinae. Also those tend to be quite curvy.

 

Im not saying with certainity. But to me, this looks like crocodiliform (Dyrosaurus sp) jaw section.

But I would double check it.

Also if you have exact locality.

But dont have Crocs long, hollow roots ? Or is Dyrosaurus different ? Because the roots on this thing are very thick. And If it turns out to be really Dyrosaurus sp., is it still rare ?

Sidi Chenan, If that helps.

Would you be able to take good picture of the root?

In that location Zarafasaura oceanis is only described plesiosaur far as I know.

 

But Pachy might know more about the topic than I do.

I'll do that tomorrow, when im back Home and i can use my good camera. Migth be a positional tooth ?

nice jaw, I am unsure what it is, more croc

Great Easter-Gift!

Yup, these teeth have carinae, which plesiosaurs don't have. So the teeth, for one, clearly aren't plesiosaurian. And while the teeth appear to be fitted to the jaw, the jaw isn't plesiosaurian either, with the bulbous structures observed being crocodilian rather than either plesiosaurian or mosasaur. The root on the tooth visible in the last photograph also points in this direction, as mosasaur teeth have a bulbous part just below the neck of the crown. Dyrosaurid crocodile therefore seems like a reasonable suggestion...

Is Dyrosaurus quite common or more rare ? 

I just want to know how rare it is in the end.

In general, jaws aren't all that common, as animals only have one set of them. At the same time, crocodile jaws - while less common than those of mosasaurs for the sheer number of species and individuals present, as well of size of exposure searched - are a lot more common than plesiosaur jaws.
