I really like the speculative idea that ceratopsians had quills on their tail.
The early ceratopsian Psittacosaurus had feather-like quills on their tail, which means later relative could’ve as well.
To anyone against this possibility, all I can say is we have no proof for or against it.
So for now, this is how I choose to display them.
Though in the possibility that we manage to find proof that suggests otherwise, I’ll change this.
