Three new species of polychaete jaw apparatuses from glacio-marine sediments of Cape Melville Formation (Lower Miocene) are reconstructed and described:
Ophryotrocha antarctica sp. n.,
Drilonereis polaris sp. n., and
Lumbrineris fossilis sp. n. Incomplete jaw apparatuses:
Ophryotrocha sp, A and
Ophryotrocha sp. B, and isolated jaws of
Glycera sp. are also described. Fossil jaw apparatus of juvenile ontogenetic stage of
Ophryotrocha Claparède et Metschnikov is here reported for the first time. Comparative analysis of fossil and Recent jaw apparatuses from Antarctic seas is given.
