And the type specimen is a subadult.

Micropachycephalosaurus is also a bit over a meter long.

I was just trying to think of an extant analogue for a (relatively)
little, spine-covered omnivorous dinosaur, and thought of hedgehogs.
Suddenly I realized how prescient the name "Echinodon" ("hedgehog
tooth") was! (Echinodon was named for the spines on its teeth, but it
turns out that the rest of the animal was probably covered in quills,
at least if it was like its relative Tianyulong.)
