Some questions & feathered Allosaurs?
A few questions, mainly about the "correct" species names for the following
1) _Sauropelta edwardsorum_ or _S. edwardsi_?
2) _Edmontonia longiceps_ or _E. logiceps_?
3) _Gargoyleosaurus parkpinorum_, _G. parkinorum_, or _G. parkpini_?
4) _Tenontosaurus tillettorum_ or _T. tilletti_?
And while we're at feathered theropods, personally I believe that maybe
feathery integument evolved somewhere in the neotetanurae (is that still a
valid clade?) after the split from the spinosauroids. Perhaps the hatchlings
needed insulation, I do not know, but maybe a neotenic feature allowed the
very first coelurosaurs retain their plumage into adulthood. From then,
feathers developed further in the Tyrannoraptora, filling the role of
display, and eventually aiding in the evolution of flight. (of course, i may
be wrong on all counts here)
But recently I have been contemplating the presence of feathers in some of
the huge coelurosaurs like the tyrannosaurs & therizinosaurs. Maybe the
adults of the large species lost their "dino-fuzz" in maturity, but retained
certain features into adulthood. I recall a somewhat updated Greg Paul
picture in the Scientific American Dinosaurs book that depicted
_Tyrannosaurus bataar_ facing off with a small group of _Therizinosaurus
cheloniformis_ Old picture, but this time the tyrannosaurs had a fringe of
feathers along the lower edge of their arms. Makes me speculate & dream up
of all sorts of things; perhaps showing male tyrannosaurs raising their arms
to show a flash of colour during the mating season? In any case, I've begun
restoring my tyrannosaurs with a short & fuzzy mane along the back of their
necks as well as a small caudal fan at the tips of their tails. (too bad i
don't have a scanner...)
And with the porcupine-tailed psittacosaur, suddenly feathered
ornithischians don't look so bizarre to me either. Maybe basal ornithopods
like _Hypsilophodon_ had some primitve fuzzy integument, a feature that
maybe newly hatched iguanodonts & hadrosaurs possessed. At the moment
though, the thought of giving my Triceratops a porcupine tail is still too
bizarre to contemplate. (Though you never know what you may find out...)
And I just had a horrifying thought... feathered & fuzzy ankylosaurs,
stegosaurs & sauropods??????!!!
