While I agree that “halfteeth” is rather awkward in its application to toothless dinosaurs, I rather like the term, and how it complements “sharpteeth” and “flatteeth” as a dietary denominator. Actually, it’s only slightly more problematic than using “flatteeth” to refer to herbivorous dinosaurs, as not all of them had teeth, either. Perhaps the leafeaters (or sharpteeth, for that matter) would use “halfteeth” as a term, not knowing or caring that
Struthiomimus and
Oviraptor don’t have teeth. At any rate, it’ll be included in the glossary, probably accompanied by a footnote in the “Notes” section.

I like the term “flowing sniffer” as well; I’ll be using it, too.
Maiasaura does have a sort of a crest, but compared with other hadrosaurs like
Corythosaurus and
Parasaurolophus, it’s not much more than a lump on the forehead, and so far, yours is the only name I’ve seen anyone come up with for that dinosaur.

: (It’s rather incredible just how difficult
Maiasaura is to name.)
“Flower dust” and “Landwalker” have already been used in the LBT series to refer to pollen and terrestrial animals respectively, but I can add your terms to the list anyway.
The one term I don’t think I’ll be adding is “Horned Clawhand”, as
Irritator does not appear in the canon LBT series. (I suppose I could add another section to the glossary devoted to dinosaur species that appear only in fanfics, but not in the LBT films, but I’d just as well not bother unless I receive a substantial amount of urging to do so.) However, “clawhand” strikes me as a good name for
Baryonyx, so you’ve still made a contribution with that term. (Incidentally, the book
The Land Before Time: The Illustrated Story refers to the
Struthiomimus that tries to steal Littlefoot’s egg as a “claw-hand” as well.)
Thanks for the terms, Kacie!
