lolman1c Posted January 2, 2016 Share Posted January 2, 2016 Just checking this is a real Mosasaur jaw. It didn't say but I also believe this to be a composite? (is that true?) I'm okay with that as I bought it knowing that a composite isn't the natural jaw but it's cheap and a lovely display piece so I think my main concern is if the teeth are real. Also just a small question... I know a composite has the real teeth and I know that a composite isn't a natural jaw but there are many different descriptions on what a composite is (crush bone, minerals of where the jaw was, crushed fossils or just normal stone carved into a jaw....) so I was wondering if someone could tell me how they make these?

Troodon Posted January 2, 2016 Share Posted January 2, 2016 In my opinion the only thing that is real with this jaw are the crowns of the teeth. The roots are fake and the jaw bones typically made from bone looks like plaster. Edit: Forgot to address your composite question. For me a composite is an assemblage of real bones and teeth from different animals of the same species to produce a finished product. Your specimen is not a composite but a complete fabrication to produce something that looks like a jaw using real teeth Link to comment Share on other sites More sharing options...
izak_ Posted January 2, 2016 Share Posted January 2, 2016 I agree with Troodon. You can see the 'grain' of the plaster (grain?) in the jaw. Link to comment Share on other sites More sharing options...
Slowpoker Posted January 2, 2016 Share Posted January 2, 2016 This one is a composite. I agree with the above. Link to comment Share on other sites More sharing options...
lolman1c Posted January 2, 2016 Author Share Posted January 2, 2016 When you say the crown do you mean the darker colour areas? Link to comment Share on other sites More sharing options...
Troodon Posted January 2, 2016 Share Posted January 2, 2016 When you say the crown do you mean the darker colour areas? Yes the crowns are the teeth less roots. See my edit in my first post. Link to comment Share on other sites More sharing options...
lolman1c Posted January 2, 2016 Author Share Posted January 2, 2016 Yes the crowns are the teeth less roots. See my edit in my first post. Hmmm, Thanks for the information. I have contacted the seller about this as he accepts returns and hasn't sent the item yet. Would you know any sellers selling composites you would be happy with buying?

Would you know any sellers selling composites you would be happy with buying?Yes, Dino Deals UK, Damien is a very honest seller who I bought my genuine (minus the roots) globidens jaw from. He has a store on eBay and a web store and also stocks natural jaws (now out of stock because I bought it) and other genuine fossils, he details everything about each fossil, and whether its composite, genuine or enhanced.

This one certainly does, if you do send him a message over eBay, tell him that the guy who bought the jaw sent you. Link to comment Share on other sites More sharing options...

snolly50 Posted January 2, 2016 Share Posted January 2, 2016 Before I make another stupid mistake does someone want to okay this before I buy it. XD At a cursory glance the positioning of the fossil on the plate screams "arranged." It just doesn't look like a natural piece. It looks like thousands of others that are offered for sale. Given that it is not unattractive, nor is the original one you posted; it would to my mind not be a bad thing to own and display - as long as the price was no more than for a handful of nice crowns and the owner was aware of the nature of the item. Good luck and have fun. Please don't be disheartened. It's just that the type of fossil that's caught your attention is a cottage industry in its native country. Human beings, who are almost unique in having the ability to learn from the experience of others, also are remarkable for their apparent disinclination to do so. - Douglas Adams, Last Chance to See Link to comment Share on other sites More sharing options...

I think I come across in my posts as upset... I am not upset and knew that the only things real were the teeth when I was buying it. I just don't like the idea that the sellers are lying in their description (or at least unaware of what they are selling). It is supposed to be made of bone and not plaster (as a bone composite will be less likely to break and in my mind would look better). I only paid £20 for this piece as it was the teeth I was looking for but again, if they are saying it is bone but it is plaster than that isn't good.

Runner64 Posted January 3, 2016 Share Posted January 3, 2016 Most mosasaur jaws you see for sale from Morocco are composites. Almost all the ones you will see will be fake. As Troodon already mentioned, they use a real crown but use plaster, sand, and and ground up bones to create the roots, jaw, and matrix on these fossils. I think you'd be better off trying to find a different fossil that is 100% authentic. Link to comment Share on other sites More sharing options...
Auspex Posted January 3, 2016 Share Posted January 3, 2016 ...but use plaster, sand, and and ground up bones to create the roots, jaw, and matrix on these fossils... They also use real bone, but non-fossil.

Auspex Posted January 3, 2016 Share Posted January 3, 2016 They 'distress' it, and stain it. One that I checked for a friend smelled of burning hair when probed with a red-hot nail.

lolman1c Posted January 3, 2016 Author Share Posted January 3, 2016 I don't mind it... I think I misunderstood what you were all saying. I thought you meant the entire thing but the teeth was made from plaster of Paris. XD Which would mean it would probably fall apart... as a cheap £20 display peace with six real teeth I am happy with it. (which i what I thought it would be). I would buy a natural one but I dislike spending over £50 on anything for my collection. Link to comment Share on other sites More sharing options...

Thank you but I have run out of spare money now. XD Only had £30 left I was comfortable with spending (as bills and rent is coming up soon as well as food to keep me alive ) so I spent £20 on the display piece... Again I bought it with the knowledge that only the teeth were original but people saying it was fake kinda freaked me out for a second... Link to comment Share on other sites More sharing options...

Yes that is the worry with jaws, I posted my globidens jaw here with the knowledge that it was real minus the roots. Two people said it was fake, which worried me, but then it turned out that it was real since the jaw fits together. That's what I'm seeing of course, I have to wait till Tuesday to verify.
