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 />

Hart and Pakhapites fusus (Bose & Kar)<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 />

Harris, 1974 conform with those of<br />

subfamilies Grevillioideae and<br />

Lewalanipollis gen. nov., and pores of<br />
