Researchers identified the creatures by their “degenerated” color and “extremely long” beak, according to a study.
Frequently included in this classification are teeth showing no more than about 1 – 2mm of white opacity at the tip of the summit of the cusps, of the bicuspids or second molars.

Chalky teeth and derivative terms ("chalky molars", "chalky enamel") have received widespread exposure as a metaphor for malformed teeth with ...
People with amelogenesis imperfecta may have teeth with abnormal color: yellow, brown or grey; this disorder can affect any number of teeth of both dentitions. Enamel hypoplasia manifests in a variety of ways depending on the type of AI an individual has (see below), with pitting and plane-form defects common. [ 4 ]
