Ok.Here's what I don't understand.

The animal chosen as a mount must be large
enough to carry the beast rider (Medium or Large for a
Small character; Large or Huge for a Medium character).

At 4th level, a Medium beast rider can also
choose an allosaurus, ankylosaurus, arsinoitherium,
aurochs, bison, brachiosaurus, elephant, glyptodon,
hippopotamus, lion, mastodon, megaloceros, snapping
turtle (giant), tiger, triceratops, or tyrannosaurus as
his mount.
If I'm not mistaken, brachiosaurus and tyrannosaurus, are gargantuan monsters. I mean, doesn't this contradict the large or huge rule?
Also, since we're on the subject, I was wondering if a samurai can choose the Beast rider archetype since he is an alternate class of the cavalier.
If anyone can enlighten me, I would be grateful.
