Comprehensive Study

Results of comprehensive study of the Kholokhovchan floral assemblage collection is summarized. These plant fossils were collected in 1978 by E. L. Lebedev from volcanogenic deposits in Penzhina and Oklan rivers interfluve, North-Eastern Russia. This assemblage was previously known as a list of Lebedev’s preliminary identifi cations only. He had suggested that the Kholokhovchan assemblage is correlative to the latest Albian — early Turonian Grebenka flora from the Anadyr River middle reaches. However, our study demonstrates that the Kholokhovchan assemblage is most similar to the presumably the Turonian-Coniacian Arman flora of the Okhotsk-Chukotka volcanogenic belt and, therefore, should be dated as the Turonian-Coniacian or Turonian.

Floral Assemblage

During the geological mapping in the Boskovice Basin, two new palaeobotanical localities in Veverské Knínice and a locality in Veverská Bítýška have been found. The most abundant flora comes from the Veverské Knínice localities. Conifers dominate in the floral assemblage. Pteridosperms are also relatively common, whereas ferns and sphenopsids are rare. These localities are assignable to the Padochov Formation, Říčany Horizon of the Permian (Rotliegend, Asselian) age. The subsequent Veverská Bítýška Formation belongs still to the Asselian. This formation contains Chudčice Horizon that yields very poor conifer flora at the Veverská Bítýška locality. Permian system is a period of progressing aridity in Moravia. Only fossiliferous horizons represent spans with higher humidity that enabled plants to live. However, the climate was not so humid, but it was rather seasonal, because pure hygrophyte plants lack in the assemblage, on the other hand, “xerophyte” plants, like conifers, dominate here.

Floral Assemblage

The limnology and sedimentary diatom flora of fourteen lakes and ponds from the Windmill Islands, East Antarctica, is presented. Saline lakes, saline ponds and freshwater ponds are represented in this dataset. The Windmill Island lake diatom flora represents an intermediate floral assemblage between that of the freshwater lakes of the Larsemann Hills and the saline lakes of Vestfold Hills, East Antarctica. Variations within this assemblage are related to water chemistry variables in the Windmill Island lakes. In particular, a lakewater salinity/phosphate gradient can explain the variation observed in the sedimentary diatom flora of the lakes and ponds included in this study.
