(Amer. J. Dent. Sci., 9, 337 [n.n.]
NcZ) "star tooth"

(Smithson. Contr. Knowl., 14 (6), 102. NcZ))
AS-tro-don (Gr. astron "constellation, star" + Gr. odon "tooth") (m)
In 1859 Dr. C. Johnston briefly mentioned the teeth of a "thecodont saurian" he named
Astrodon in a paper on the teeth of Hadrosaurus, but provided no description.
He sectioned one tooth for viewing under a microscope, and the name Astrodon alludes
to the rather starburst-like "multitude of minute tubuli radiating from the narrow elliptical
section of the pulp cavity" as later described and illustrated by Leidy.
The external form of the teeth was spoon-shaped, typical of brachiosaurids.
Treated by some researchers as a valid senior synonym of Pleurocoelus.
