sediments of the Zhuravka and Abrosimovo<br />
horizons (upper Oligocene, lower Miocene),<br />
the Pseudokomewuia Beds are included into<br />
local stratigraphic scheme. According to<br />
results of comparative analysis, similar and<br />
distinctive features of Oligocene-Miocene<br />
dinocyst assemblages from West Siberia,<br />
China and North America are elucidated.<br />
Based on palynological data, the local<br />
stratigraphic scheme of higher resolution is<br />
suggested for subdivision of Oligocene and<br />
Miocene deposits in southern part of West<br />
Siberia (Baraba and Kulunda lithofacies<br />
regions).<br />

沉 积 (Tupe 组 ) 孢 粉 = Palynology of late<br />
Palaeozoic sediments (Tupe Formation) at La<br />
Herradura Creek, San Juan province,<br />
Argentina. ( 英 文 ). Verge M. Alcheringa, 2008,<br />
32(4): 339 - 352<br />
Palynomorph assemblages recovered from<br />
the Tupe Formation at La Herradura Creek,<br />
San Juan province, Argentina, are analysed.<br />
The middle section of the sequence includes a<br />
marine fossiliferous interval belonging to the<br />
Tivertonia jachalensis-Streptorhynchus<br />
inaequiornatus (T-S) Faunal Biozone, recently<br />
ascribed an Early Permian age. The section<br />
below the marine fossiliferous unit yielded<br />
palynofloras typical of previously described<br />
'Tupense' assemblages. The palynoflora<br />
recovered from beds above the marine horizon<br />
is diverse, relatively well preserved and<br />
includes species never recorded from the Tupe<br />
Formation. This latter palynoassemblage<br />
includes species diagnostic of Early Permian<br />
palynofloras such as Converrucosisporites<br />
confluens (Archangelsky & Gamerro)<br />

Men ndez. Correlations with assemblages<br />
from western Argentina and other Gondwanan<br />
regions suggest an Early Permian age (not<br />
older than Asselian-Sakmarian) for the upper<br />
part of the sequence, supporting the age<br />
attributed to the T-S Biozone<br />

( 其 他 ). Llorens M. Ameghiniana, 2008, 45(2):<br />
273-288<br />
Eighteen species of disperse trilete apiculate,<br />
murornate, tricrassate and perinate spores<br />
from the Punta del Barco Formation, in the<br />
Meseta Baquero area, Lower Cretaceous of<br />
Santa Cruz Province, are described. They<br />
belong to the genera Gleicheniidites, Clavifera,<br />
Ornamentifera,<br />
Ceratosporites,<br />
Concavissimisporites, Staplinisporites,<br />
Retitriletes and Lygodiidites. Besides, a new<br />
genus for a perisporate spore -Capsispora- is<br />
proposed, an indeterminate apiculate form and<br />
two new species of the genus Gleicheniidites,<br />
are described. Finally, some paleoecological<br />
implications are given from the study of this<br />
spores association, which are related to stress<br />
conditions by the strong volcanic activity<br />
during the sedimentary deposition of this unit.<br />

Abundant and diverse proteaceous-like<br />
triaperturate pollen from Campanian-<br />
Maastrichtian sediments in the Otway Basin,<br />
southeastern Australia are systematically<br />
documented and compared with pollen of<br />
extant Proteaceae. Segregation of fossil and<br />
extant pollen types has been effected on<br />
apertural characters of which six states have<br />
been identified. Apertures are colpoid, poroid<br />
or porate. Pores of Propylipollis Martin &<br />

subfamilies Grevillioideae and<br />
