Pachyrhinosurus

[LONEWOLF <s086529@student.uq.edu.au>]

Good day all,

I remembered a few years ago reading that pachyrhinosaurus, found with a
shelf-like ridge on its nose, was represented by only two finds, and
therefore there was some argument as to whether in fact, this ceratopsian
had a ridge, or whether this was the base of an immense horn that had
broken off due to a fight or some pathological process. Any news on
this?

Thank you kindly,

Greg
