A new take on Yehuecauhceratops.

Yehue copy.jpgThe danger of having extremely fragmentary dinosaur remains like the ones found in Mexico is that they are  bound to different interpretations… and if we are not careful we can end up in opposite directions when it is time to reconstruct the animals. Meet my own take to a male and a female Yehuecauhceratops mudei, the  now famous  mid-sized ceratopsian from the Late Cretaceous Coahuila, Mexico.

I have been aided by Angel Ramírez in the reconstruction. As you can see I have also increased and bloated the size of the nostrils according to the latest trends of research… the space is massive so it is justified!

We followed closely the very fragmentary remains of the skull (specially the frill). And this is the final result… It appears to have been recognised by (among others) Peter Dodson as a closer relative to  Nasutoceratops than to Chasmosaurus and the model used for the frill is more like  than the aforementioned or even better: Avaceratops. So those were the main  references to follow.  The main characters are a reduced squamosal with three undulations (maybe bases for hooking keratinous display structures), a rugose lateral bump and expanded parietals.Yehuecauhceratops-2.png

Yehuecauhceratops mudei NEW ver-2 with skeleton.jpg  Here is his own most recent restoration of  the skeleton by Angel Ramírez. I specially thank him for his help and assistance… and allowing me the artistic license of including a flock of ornithomimids in the background (they are not flocking this way this time!)… together with the de-rigueur hadrosaurs .

This restoration may change in the future  once again, but for the time being this was the best we could come with.

UPDATE. An extra note requested by Angel Ramírez: his reconstruction used the silhouette and skeleton drawing of Scott Hartman of Avaceratops and modified it in what concerns the skull,  so that it looks more like a nasutoceratopsine.

The interpretation is based on the description of Rivera-Sylva, Hendrick and Dodson, 2016. A centrosaurine (dinosauria: ceratopsia) from the Aguja Formation (Late Campanian) of Northern Coahuila, Mexico.
