"Strange lizard" might be a better transliteration. The name refers to the
vertebrae, which Marsh thought differed from those of other dinosaurs in not
being pneumatic, merely deeply excavated along the sides. Unfortunately,
better _Allosaurus_ specimens do show typical theropod pneumatization, so the
name is a bit of a misnomer.

"Broad lizard" might be better here. This probably refers to the stout hind
limbs and general large size of the skeleton, which the author (von Meyer)
cites several times in his article. It has nothing to do with the plate-like
pubis, etc., which were absent from the original specimen.

Not just oak, but any tree. Marsh's idea was that _Dryosaurus_ lived in a
forested environment where it could browse leafy vegetation.

In Marsh's original article, he implies that he at first mistook the tail
vertebrae for those of a mosasaur. This is doubtless the source of the
"deceptive" part of the name.
