Ankylosaur scute?

[DINOMAN91]

I’ve came across this piece it’s from Morocco Kem kem beds looks like armor scute what does everyone thing?

I see nothing ankylosaurian.  They have a very distinctive texture.  Are ankyosaurs found in the Kem Kem beds?

[DinoFossilsUK]

Not an Ankylosaur scute (they're not known from Kem Kem and the shape/testure isn't right), but it may well be a sauropod scute.

[Troodon]

Agree not Ankylosaurid.  Not present in KK deposits.

Titanosaurids are known to have osteoderms but I have not seen any publications on those from the KK.  The ones I've seen from other african/South American localities have a rough texture, central ridge or are pointed not flat with a smooth texture.  I have several like yours and were sold as sauropod scutes.  However until I see a publication that supports that identification it's unknown what it is.

 

Example of one from SA

I don't even see this as bone.  I can't see any texture other than what seems to be sandstone.
