Four Pachyrhinosaurus

Here we have four Pachyrhinosaurus with different levels of integument, sorta. First is my usual style. Second has packed on some fat, in case they didn't have a protofeather coat for Cretaceous Alaska. Third is our feathery version, fluffed up and ready for the cold. And, last but not least, same guy as three, only now in breeding mode, decked out with long display feathers and flashier colors for the ladies (I have no idea if the keratin would've been able to change as well).

Inspired by Mark Witton's blog post about his own feathered Pachyrhinosaurus reconstruction. Base Pachyrhinosaurus was traced directly off of a Scott Hartman skeletal.
