[f. Gr. σκωληκ(ο)-, σκώληξ worm + ὀδοντ-, ὀδούς tooth.]
The jaw of an annelid worm, found as a microfossil in some rocks.
1933Croneis & Scott in Bull. Geol. Soc. Amer. XLIV. 207 Recent investigations have shown that annelid worm jaws..are actually common paleontologic objects. Because of their probable importance in future micropaleontologic investigations, we are, for convenience, here proposing for these fossils the designation Scolecodonts. 1961J. Challinor Dict. Geol. 176/1 Scolecodonts are found fossil [sic] from the Ordovician onwards. They are composed of silica and chitin, the latter becoming carbonized to a jet black appearance in the process of fossilization. 1989Nature 5 Jan. 28/2 Among the objects of interest are acritarchs,..chitinozoans, scolecodonts,..and pteridophyte spores. |
