Kem Kem Material Sale Red Flags


Recommended Posts

Posted here are some very nice fossils for collectors just be aware that the descriptions might not be as advertised.

 

Seller calls this a Pterosaur claw, I'm not sure what it belongs to but nothing is published to support his claim

Seller list this as a superb Spinosaurus phalanx toe bone.  Looks more like a hand bone, carpal or metacarpal.  Also we do not know if it comes from the species Spinosaurus better described as Spinosaurid indet.

Seller is describing this as a Spinosaurus caudal vertebra.  Spino caudal vertebrae are typically more box shaped so I doubt it's from one.  Not certain what's it's from.

Seller is offering a very nice upper and lower jaw bone from the Pterosaur Alanqa saharica. I question if these are associated and if either are lowers jaw sections.. Ibrahim's reconstructed jaw shows the mandible as being much thinner than the upper and more like the offering.

I also will add that isolated upper jaws may be hard to identify to a specific species and are better described as Azhdarchoid indet.  since along with Alanqa the new species Xericeps may have similar uppers but it's currently unknown. 

 

Seller is offering this pair of bones as a Spinosaurus Phalanx bone and Claw.  Unfortunately the phalanx is a hand bone, carpal and not associated with the claw.  The claw may belong to one of the Spinosaurid's but without a ventral view it's uncertain its one.

Offering for a large toe bone from a Spinosaurus.  Looks more like a Carpal from an unknown Spinosaurid.

Offering big money for this Spinosaurus complete foot.  Unfortunately there are many things wrong with this foot.  Most of the phalanx don't fit their positions and may not be Spinosaurid.  The claws are undersized for the foot and cannot determine if they belong to a Spinosaurid with the photos that are provided.

A foot should look like this

Remind buyers that all teeth offered as Spinosaurus may not belong to that species but one of the other Spinosaurids that may be present in that fauna either currently described or yet to be identified

I guess if all you are after is looks, these are for you. But at that point, I think I would have a quality cast that is accurate, than scabbed together miss identified specimens and save a bunch of money.

One of the sellers from above added material.

 

A number of these type of bones were added and described as Spinosaurus Toe bones.  This morphology of bone is a carpal from a unknown Spinosaurid.  All very nice.

This bone was listed as a Spinosaurus hand bone,  carpal.  I think it's much to thin to be from a Spinosaurid and although not completely sure might even be a metatarsal from a crocodylomorph

Lots of new teeth were listed and described as Dromaeosaur.   Most are Abelsaurid some are, Juvie Carch or indeterminate but none are from the species Dromaeosaur.  Unfortunately no small teeth from the Kem Kem can be assigned to a species or even genus. 

Sample of those being offered.

Great information. I saw this for sale by the same seller, it is listed as a Pterosaur dentary bone (Alanqa). Would you agree with the identification and if it is indeed Pterosaur?.

Thanks and I do believe this is the dentary of an Azhdarchoid and most likely Alanqa.   Very different than the other one he posted.

Actually this is a Genuine Pterosaur Lower Jaw! But we can not forget that besides Alanqa saharica, we now have a new pterosaur Azhdarchoid discovered in the beds of Kem Kem, that is, the Xericeps. So, as it is very fragmented and incomplete, it is difficult to be sure if it is Alanqa, Xericeps, or a new pterosaur Azhdarchoid that has not yet been discovered. In my opinion for now, the best labeling would be: Lower jaw of Pterosaur Azhdarchoid indeterminate.

 

For comparison, here are two jaws: upper and lower that are deposited in my private collection. They are practically complete, whose morphology closely resembles the holotype of the Alanqa saharica.

Congratulations, excellent posting my friend @troodon!

Is It real, or it's not real, that's the question!
