While they are dermal in origin, aren't they
"The most diagnostic features of Coelurosauravus
are the chameleon-like frill at the
back of the skull roof, formed primarily by
the squamosals, and the presence of numerous
long, rodlike bones that supported a
lateral gliding membrane"
from Frey /et al/ SCIENCE VOL. 275 pg1451-2
They also note that the structures have been
mistaken for various other boney elements, such
as ribs and even fin rays in fish.
