Ungual dinosaur?

[PaleoMexico]

I have a material from the late Mesozoic from northeastern Mexico, it could be ungual from a dinosaur, what do you think?

I'm not seeing any bone texture to this item. Nor am I seeing any bilateral symmetry, or bone morphology.

I think this is an interestingly shaped rock.  Wait for other opinions.

 It does have the shape of a sauropod ungual but I agree with Tim just a cool shaped rock.  That area has very late cretaceous dinosaurs so keep looking.

 Tiene la forma de un ungual saurópodo, pero estoy de acuerdo con Tim, solo una roca con forma genial. Esa área tiene dinosaurios del Cretácico muy tardío, así que sigue buscando

I took an X-ray and the posterior morphology of an ungual phalanx is perceived

Sorry still do not see what you are seeing.  Claws typically have blood gloves, not seeing any.  Do you know what geologic Formation you are in?

In the X-ray, the posterior part (the most extensive) of the so-called "ungual" shows a clear section that looks like encasing rock. Inside there is a concave silhouette that makes me think it is the cotyla tubercularis. The material comes from the La Joya Formation

I know nothing about that Formation.  The little that is online say it's primarily a mid jurassic marine deposit and I cannot find any vertebrates that have been published...The only possibility, as I said before, is a sauropod but the there is no blood groove and the ridges on one side are not typical.  If real real it would be great.  I suggest you taking it to a museum where there is a dinosaur paleontologist that can hand examine it.
