Here's the story as I understand it. I'm sure there will be gaps and
gaffes, but that's what all these other gifted people are here for.
When I was a kid (in the 80's) the story I got through various
channels was that Trachodon was a junior synonym for Anatosaurus,
and that it wasn't an aquatic animal. The tail couldn't have been
much good for swimming because a network of ossified tendons held it
rigid, the tooth batteries could have chewed a lot more than just
aquatic vegetation, and the old duck-bill has been given a good set
of cheeks, so the mouth doesn't reach very far up the side of the
head. Oh, yeah, and the webbed front foot is gone, replaced by a
meaty mitt formed from the three middle fingers. I think that some
conifer material might have been recovered from a hadrosaur torso,
which would indicate a coniferous diet for at least one of the
beasts, but that might just be my fevered imagination.
Just about the time I got used to Anatosaurus, it too got deep-sixed
(I don't know when all this was published, but I didn't learn about
it until fairly recently. That could just be me.).
As I understand it, Anatosaurus is now a junior synonym of
Edmontosaurus, and a really humongous former Anatosaurus is now
Mebbe we could hit up Mike Brett-Surman to give us the poop.
Well, that's all I know. See ya.
