of one to several congruently superimposed
cell sheets that together form a
plectenchyma or pseudoparenchyma.
This discovery represents the youngest
record of sheets of fossil cells, which
have heretofore exclusively been reported
from the Proterozoic and Palaeozoic,
and is one of the few examples of
cell sheets that can be attributed to macroscopic
remains with confidence. We
interpret the thalloid organism from
Antarctica as the remains of a crustose
freshwater macroalga based on its occurrence
in overbank deposits of a braided
fluvial environment and its morphological
similarity to thalli of extant freshwater
representatives of the red algal order
Hildenbrandiales.

A rich phytoplankton assemblage and
low diversity miospore microflora is described
from the Lower Famennian deposits
of the Kowala Quarry, Holy Cross
Mountains, Central Poland. This assemblage
is assigned to the Pw acritarcha
zone, which is correlated with the late
triangularis–crepida standard conodont
zones based on appearance of the acritarch
Puteoscortum williereae. Comparison
of the present palynological results
with well-documented data from
Belgium clearly indicates differences in
marine microflora composition in both
regions. The important taxa Visbysphaera
(?) occultata, Ephelopalla media,
and Palacanthus tripus in Belgium are
absent in the samples from the Holy
Cross Mountains and by contrast, the
phytoplankton frequent in Poland (Lophosphaeridium,
Dictyotidium or Cymatiosphaera)
are rare in Belgium. The
taxonomical difference between the
Holy Cross Mountains and Belgium palynoflora
may probably reflect environmental
differences: offshore and more
proximal environmental conditions respectively.
Three new species (Leiofusa
turnauae sp. nov., Lophosphaeridium
irregularis sp. nov. and Veryhachium?
kowalae sp. nov.) have been formally
instituted and two new taxa (Centrasphaeridium
sp. A and Centrasphaeridium
sp. B) are left in open nomenclature.

Samples collected by two sediment
traps located southwest of Crete in the
eastern Mediterranean (EMED) [48A
(1953 m) and 48B (950 m)] from June
2005 to May 2006 were used to study
fluxes of organic carbon, carbonate and
coccolithophores in combination with
the variations of Sr/Ca ratios in different
individually picked coccolith species.
