During the Early Cretaceous charophyte assemblages were dominated by the family Clavatoraceae, especially in low latitudinal lakes from the Peri-Tethyan basins. In higher latitudes, however, charophyte assemblages were mainly formed by early characea

Salviniales from the Late Cretaceous of the Golfo San Jorge Basin

Autor: Patricia Vallati, Marcos Calo, Andrea De Sosa Tomas, Gabriel Casal

Publikováno v: Cretaceous Research. 74:45-55

The freshwater ferns (Salviniales) are well represented in the Maastrichtian deposits of Cerro de los Fragmentos in the headwaters of the Río Chico, Golfo San Jorge Basin. The fossil material of Salviniaceae includes complete megaspore apparatuses w

A Maastrichtian terrestrial palaeoenvironment close to the K/Pg boundary in the Golfo San Jorge basin, Patagonia, Argentina

Autor: Gabriel Casal, Patricia Vallati, Andrea De Sosa Tomas

Publikováno v: Journal of South American Earth Sciences. 97:102401

In this paper, we present new palaeontological data regarding plant remains (palynomorphs, mesofossils, and leaves) from the uppermost part of the Lago Colhue Huapi Formation (Maastrichtian), at the headwaters of the Rio Chico, Golfo San Jorge Basin.
