Having a crest, ridge, or crest-like structure; describing something with a prominent raised edge or ornamental top.
From Latin 'cristatus,' the past participle of 'cristare' (to crest). Originally used to describe animals with crests, the term expanded to any structure resembling a crest.
Cockatiels, certain lizards, and even some fossils are cristate—nature loves this design because a prominent crest works great for signaling to other animals.
