Could extraordinary plume-like structures like those on Longisquama and the recently described Mirasaura be present in other drepanosauromorphs? I think it is not completely out of the question!

Look at this perfect Triassic friend. Mirasaura was a "monkey lizard" with a prominent sail on its back that wasn't really like scales or feathers. Studying these fossils also revealed that the enigma Longisquama is a drepanosaur with a fan, too. I'll tell you more at

Almost gave myself a heart attack when I didn’t see Raptor in his usual sleeping spot under his big hide. I forgot that I dug a pit under his log when I cleaned his tank so he curl up without his tail sticking out. Also didn’t remember I took a pic of him sleeping there earlier. Disaster averted
