Abstract

The palynological contents of New Albany Shale, Kentucky, U.S.A. have been analysed to reveal 17 species of trilete spores and 17 species of alete sphaeromorphs, hystrichospherids and Chitinozoa. Two new genera and 22 new species have been described.

Among the trilete spores, Cymbosporites (11 %) is associated with Fossulatisporites (10%), Auroraspora (3%) together with Ancyrospora and Hystricosporites (1% each). Among the acritarchs, Leiosphaeridia (40%), Tasmanites (10%) and Baltisphaeridium (6%) are the most prominent.

The trilete spores and the associated acritarchs suggest a Famennian age for the New Albany Shales.
