Do you agree with my identification for this Psittacosaurus?

[Archeognathus1988]

Hello together! First post by me after months of scrolling and reading through the topics 😀

 

So I got this Psittacosaurus-skull with some cervical vertebrae. It originates from the Yixian-formation near Liaoning, China. Lightly deformed but overall in pretty good condition I would say. The skull is 80mm in length and 66mm wide at the jugals. I suppose it is a juvenile specimen of the species P. lujiatunensis, around 2-3 years old. I know it's not possible to identify a juvenile specimen but at least I wanted to show it to you and perhaps someone agrees with me 😉
