Maria Farinha Formation
The Maria Farinha Formation is a geological formation of the Parnaíba Basin in Pernambuco, northeastern Brazil whose strata date back to the Danian stage of the Paleocene, or Tiupampan in the SALMA classification. The formation comprising limestones, dolomites, marly and sandy limestones has been deposited in a shallow marine platform environment. The formation has provided fossils of reptiles and fish. Description The Maria Farinha Formation crops out in the Parnaíba Basin in the northeastern state of Pernambuco of Brazil. The formation registers the Cretaceous-Paleogene boundary at the base of the formation, where it overlies the Maastrichtian Gramame Formation. The thick formation is overlain by the Eocene Tambaba Formation which is overlain by the Plio-Pleistocene Barreiras Formation.Ribeiro de Santana et al., 2011, p.5 Fossil content The following fossils were reported from the formation:

Santa Lucía Formation
The Santa Lucía Formation is a Maastrichtian to Paleocene (Danian) geologic formation in Bolivia. Fossil ornithopod tracks have been reported from the Cretaceous lower part of the formation.Weishampel, et al., 2004, pp.517-607 It is the type formation of the Tiupampan South American land mammal age. Description The Santa Lucía Formation is a formation of the Potosí Basin in Bolivia dated to the Paleocene, 60 to 58.2 Ma.Sempere et al., 1997, p.709 It overlies the Cretaceous El Molino Formation and is overlain by the Cayara Formation.

South American Land Mammal Age
The South American land mammal ages (SALMA) establish a geologic timescale for prehistoric South American fauna beginning 64.5 Mya (unit), Ma during the Paleocene and continuing through to the Late Pleistocene (0.011 Ma). These periods are referred to as ages, stages, or intervals and were established using geographic place names where fossil materials where obtained.Flynn & Swisher, 1995 The basic unit of measure is the first/last boundary statement. This shows that the first appearance event of one taxon is known to predate the last appearance event of another. If two taxa are found in the same fossil quarry or at the same stratigraphic horizon, then their age-range zones overlap. Background South America was an island continent for much of the Cenozoic, or the "Age of Mammals". As a result, its mammals evolved in their own unique directions, as Australia and Madagascar still have today.

Alcidedorbignya
''Alcidedorbignya'' is an extinct pantodont mammal known from the Early Paleocene (Tiupampan SALMA, ) Santa Lucia Formation (, paleocoordinates ) at Tiupampa near Mizque, Cochabamba, Bolivia. Following a naming convention established by pioneering Argentine palaeontologist Florentino Ameghino (i.e. combining the first name and surname of a prominent scientist), the genus name honours French naturalist Alcide d'Orbigny. Description Estimated 25 cm head-body length and 500 grams, this was a small squirrel sized animal, terrestrial with possible scansorial habits, and either herbivorous or omnivorous. ''Alcidedorbignya'' is one of the oldest and most primitive of the pantodonts and the only pantodont genus known from South America. Not only have some scientists questioned the age of the type locality, instead advocating an Asian origin for the pantodonts, ''Alcidedorbignya'''s bare existence obscures the origins of the already enigmatic pantodonts. Taxonomic similarities indic ...

Salamanca Formation
The Salamanca Formation is a geologic formation in the Golfo San Jorge Basin of central Patagonia that yields well-preserved, well-dated fossils from the early Paleocene. Studies of these fossils are providing new data on plant and animal diversity following the Cretaceous–Paleogene extinction event, end-Cretaceous extinction event. Material was copied from this source, which is available under a creativecommons:by/4.0/, Creative Commons Attribution 4.0 International License The Salamanca Formation crops out in the San Jorge Basin in southern Chubut and northern Santa Cruz provinces, Argentina, overlying the Cretaceous Chubut Group and is part of the Paleocene and Eocene Río Chico Group. The formation yields abundant plant remains as well as fossils of Invertebrate, invertebrates, marine macrofaunas, Reptile, reptiles, and Mammal, mammals. The formation consists primarily of estuarine to shallow marine deposits. Palynological analysis of the Salamanca Formation shows low flora ...

Lefipán Formation
The Lefipán Formation is a Maastrichtian to Danian, straddling the Cretaceous-Paleogene boundary, geologic formation of the Cañadón Asfalto Basin in Chubut Province, Patagonia, Argentina. The up to thick stratigraphic unit comprises mudstones, sandstones, siltstones and conglomerates, sourced from the North Patagonian Massif and deposited in a deltaic to shallow marine environment with a strong tidal influence. The basin that in those times was connected to the widening South Atlantic Ocean with a seaway connection to the Austral Basin and possibly with the Pacific Ocean. The formation has provided unique fossil flora assemblages dating to the Cretaceous and Paleogene ages, and are characteristic of the early Cenozoic after the extinction of the dinosaurs. The occurrence of the same taxa in the Maastrichtian and Danian successions suggests that the Cretaceous-Paleogene extinction event did not affect aquatic plant communities, which retained approximately similar structure a ...

Pucadelphys
''Pucadelphys'' is an extinct genus of non-marsupial metatherian. The genus contains a single species, ''P. andinus''. Fossils of ''Pucadelphys'' have been found in the Santa Lucía Formation in Tiupampa in Bolivia.''Pucadelphys''
at .org


Description

''Pucadelphys'' was small and likely to have eaten insects. It had a long tail, although incomplete on the best preserved fossils. It is possible that the tail was longer than (or at least as long as) its body. 17 vertebrae were preserved, and its estimated that there was 5 to 10 additional vertebrae originally. It is regarded as partially arboreal, and partially terrestrial. It may have been social, as mo ...

Golfo San Jorge Basin
The Golfo San Jorge Basin ( es, Cuenca del Golfo San Jorge) is a hydrocarbon-rich sedimentary basin located in eastern Patagonia, Argentina. The basin covers the entire San Jorge Gulf and an inland area west of it, having one half located in Santa Cruz Province, Argentina, Santa Cruz Province and the other in Chubut Province. The northern boundary of the basin is the North Patagonian Massif while the Deseado Massif forms the southern boundary of the basin. The basin has largely developed under condition of extensional tectonics, including rifting. The basin is of paleontological significance as it hosts six out of 22 defining formations for the South American land mammal age, SALMA classification, the geochronology for the Cenozoic used in South America. At the center of the basin accumulated sediments reach more than of thickness. Oil was first discovered in 1907 and over the years it has become the second most productive hydrocarbon basin in Argentina after Neuquén Basin. St ...

Fossils of '' Coussapoa camargoi'', '' Ficus andrewsi'', '' Berhamniphyllum sp.'' and '' Archaeopaliurus boyacensis'' have been found in coalbeds in Zipaquirá and Tasco, Boyacá.

Cañadón Asfalto Basin
The Cañadón Asfalto Basin ( es, Cuenca de Cañadón Asfalto) is an irregularly shaped sedimentary basin located in north-central Patagonia, Argentina. The basin stretches from and partly covers the North Patagonian Massif in the north, a high forming the boundary of the basin with the Neuquén Basin in the northwest, to the Cotricó High in the south, separating the basin from the Golfo San Jorge Basin. It is located in the southern part of Río Negro Province and northern part of Chubut Province. The eastern boundary of the basin is the North Patagonian Massif separating it from the offshore Valdés Basin and it is bound in the west by the Patagonian Andes, separating it from the small Ñirihuau Basin. The basin started forming in the Early Jurassic, with the break-up of Pangea and the creation of the South Atlantic, when extensional tectonics, including rifting, formed several basins in eastern South America and southwestern Africa. The accommodation space in the Cañadón Asf ...
