- n. A small glistening fossil organism, discovered by Pander in Silurian and Devonian rocks in Russia, and subsequently observed in other strata in different localities, and variously supposed to be a tooth of a cyclostomous fish, or a spine, hooklet, or denticle of a mollusk or an a˙nnelid: so named from its conical tooth-like appearance. These organisms are certainly not teeth of any vertebrates, and are probably the remains of worms.
- n. Any of several extinct fishlike chordates that had conelike teeth
- n. A microfossil tooth of such an animal
