I kid, of course, but I think Dynamosaurus deserves a mention on its more famous relative's naming day as well. Tyrannosaurus, Dynamosaurus, and Albertosaurus were all named by Osborn in 1905 and although Tyrannosaurus and Albertosaurus have proven to be distinct from each other, Dynamosaurus turned out to be a junior synonym of Tyrannosaurus. If Tyrannosaurus hadn't appeared first in the publication, good ol' T. rex might not be the household name it is today and we might all stand and gape at Sue or Scotty or Stan the Dynamosaurus. The distinctive osteoderms are probably Ankylosaurus osteoderms,
Anyway, happy birthday, Dynamosaurus. I still like you, even if you never existed.
