The Mata Amarilla Formation is part of the infilling of the Austral Basin, located in Southern Patagonia, Argentina. This unit is mainly composed of grey to black mudstones interbedded with white fine- to coarse-grained ...
The South American and Antarctic Peninsula fossil record of Salviniales (water ferns): Its implication for understanding their evolution and past distribution
(Elsevier Science, 2021-12)
We compiled the fossil record of the heterosporous water ferns (Salviniales) including macro- and microfossils from South America and the Antarctic Peninsula. Both extant families, Marsileaceae and Salviniaceae, are well ...
Unusual locomotion behaviour preserved within a crocodyliform trackway from the Upper Cretaceous Bayanshiree Formation of Mongolia and its palaeobiological implications
(Elsevier Science, 2019-11-01)
Crocodyliform tracks are reported from the Upper Cretaceous (?Cenomanian-Santonian) Bayanshiree Formation in southeastern Mongolia. Ten tracks are preserved as natural casts, forming a trackway with a quadrupedal gait ...

(Departamento de Geociencias, 1998)
A new scheme of stratigraphic nomenclature is defined formally in the northern portion of the Putumayo basin. The Masaya Formation (new formation) represents the beginning of the Cretaceous sedimentation during the late ...
A proposal on the classification of systems tracts: application to the allostratigraphy and sequence stratigraphy of the cretaceous colombian basin. part 2: barremian to maastrichtian
(Departamento de Geociencias, 2002)
The Barremian to Maastrichtian interval of the sedimentary succession from the Cretaceous Colombian Basin is divided in stratigraphic sequences and in several allostratigraphic units, which include the Fómeque, Une, and ...
