A group for all creatures closer to Passer domesticus than to Triceratops horridus or Saltasaurus loricatus. Birds and their Mesozoic kin: obviously the best dinosaur clade with living representatives.

Hey Jurassic Park fans!! I just ripped the Lost World game OST and uploaded a playlist to Youtube. I personally love the music for the game. If you're interested, check it out! [link]
Why is it that Spinosaurids are rarely depicted to have feathers, when theropod lines that branched off both before and after them often are? What's with the double-standard or discrimination or whatever? What is it about the "croc-jaws" that seems to make so many artists shy away from putting feathers on Spinosaurids when they'll eagerly feather nearly anything else in the theropod lines?
Actually, they've put Sciurumimus in the Megalosauroidea line, and it has proto-feathers. Personally, I think it's a mistake to have it there. Just wishful thinking on the part of the paleotologists who found it - wanting to be the first to find a feathered non-coelurosaurian.
But there are feather types (penguins & auks) that are good for semiaquatic lifestyles. At the same time, though, you have to look at the fact that these bigger beasties would not have had the flexibility to preen all of those feathers properly for an aquatic/semiaquatic lifestyle. Their necks don't have the appropriate vertebrae and their spines are too long between the scapula and the ilium. (Plus any spinosaurid with a "sail" would have additional difficulties in the flexibility realms.)
