Looks like a tadpole version of a ceratopsian somehow. Is there a chance the material we have to date is from not fully grown individuals, so that allometry would make their proportions look not that weird (I am mostly referring to the really large skull) later as adults?

Pretty sure it's not a juvenile. Granted there isn't any published histology that I know of, but there are multiple specimens from different sites that are the same size, and all their neural arches are fused, etc. I think they're just weird little pig-like or maybe mountain-goat-like ceratopsians.
