The perforated Pediastrum Meyen s.l. species are recorded for the first time in the basal levels of the Tithonian Vaca Muerta Formation, extending its first stratigraphical record to ages as old as Late Jurassic times. Based on the ecological requirements of Pediastrum simplex var. clathratum and P. simplex var. biwaense, the previously warm paleoclimatic conditions suggested by the Late Jurassic of Neuquén Basin, are reinforced. The co-occurrence of the different mechanisms that interacted during the transport, accumulation, and early diagenesis of these sediments and their organic content would have allowed for the excellent preservation of the Pediastrum Meyen s.l. species.
在梯通统Vaca Muerta组的基底层中首次记录到了带孔的Meyen s.l. Pediastrum，将其首次地层记录时间延长到了晚侏罗世。根据青叶小檗(Pediastrum simplex var. clathratum)和biwaense小檗(P. simplex var. biwaense)的生态要求，加强了纽泉流域晚侏罗世以前温暖的古气候条件。在这些沉积物的运输、堆积和早期成岩作用过程中，不同机制的相互作用及其有机含量的共同存在，可能使米扬小檗物种得以很好地保存下来。

. NEW RECORDS OF LATE PLEISTOCENE (MIS 5) MAMMALS IN SOUTHERN ARGENTINIAN MESOPOTAMIA. New records of mammals from the Late Pleistocene of the province of Entre Ríos are presented in this contribution. The fossils come from the Salto Ander Egg Formation, a unit which is deposited in the fluvial valleys of the southwest of Entre Ríos and dated between 120 ka and 60 ka by OSL. It is interpreted that the formation sequences were accumulated during MIS 5. The paleontological content of the unit constitutes the record that best characterizes the beginning of the Late Pleistocene for South America and the MIS 5e-MIS 5c transition. In this work 12 taxa are described: cf. Ozotoceros bezoarticus (Cervidae), Morenelaphus cf. brachyceros (Cervidae), Hemiauchenia paradoxa (Camelidae),
