Holoptychius is an extinct genus of porolepiform lobe-finned fish from the Middle Devonian to Carboniferous (Mississippian) periods. It is known from fossils worldwide. The genus was first described by Louis Agassiz in 1839.
Michelinoceras is the oldest known genus of the Michelinocerida, more commonly known as the Orthocerida, characterized by long, slender, nearly cylindrical orthocones with a circular cross section, long camerae, very long body chambers, and a central or near central tubular siphuncle free of organic deposits. Septal necks are straight; connecting rings cylindrical and thin. Cameral deposits are well developed. A radula has been found in one species, with seven teeth per row. It had ten arms, two of which formed longer tentacles.
Acastoides is an extinct genus of trilobite that lived during the Silurian and Devonian. It has been found in Bolivia, France, Morocco, Poland, Turkey and the United Kingdom.
Bainella is an extinct genus of Devonian trilobites from off the coast of Gondwana. Fossils were found in the Ponta Grossa Formation of Brazil, Belén, Icla and Gamoneda Formations of Bolivia and the Gydo, Gamka and Voorstehoek Formations of South Africa. It contains three species: B. africana, B. baini, and B. cristagalli.
Francovichia is a trilobite in the order Phacopida, that existed during the lower Devonian in what is now Bolivia. It was described by Branisa and Vanek in 1973, and the type species is Francovichia branisi, which was originally described under the genus Odontochile by Wolfart in 1968. It also contains the species, F. clarkei. The type locality was the Belén Formation.
The Leduc Formation is a stratigraphic unit of Late Devonian (Frasnian) age in the Western Canada Sedimentary Basin. It takes its name from the city of Leduc, and it was formally described from the B.A. Pyrz No. 1 well in central Alberta, between the depths of 1,623.7 m (5,327 ft) and 1,807.5 m (5,930 ft), by Imperial Oil Limited in 1950. Supplementary information came from a complete section of the formation that was cored in Imperial Oil's Leduc No. 530 well between 1,633 m (5,358 ft) and 1,863 m (6,112 ft).
Zulmasuchus is an extinct genus of sebecid sebecosuchian mesoeucrocodylian. Its fossils have been found in Early Paleocene-age rocks of the Santa Lucía Formation in Bolivia. Zulmasuchus was named in 2007 by Alfredo Paolillo and Omar Linares for fossils originally described by Buffetaut and Marshall in 1991 as Sebecus querejazus. Thus, the type species is Sebecus querezajus and the combinatio nova is Zulmasuchus querejazus.
The Tiupampan age is a period of geologic time within the Paleocene epoch of the Paleogene used more specifically with South American land mammal ages (SALMA). It is the oldest SALMA age and precedes the Peligran age.
Dolichochampsa is an extinct genus of eusuchian crocodylomorph. It is the type genus and only member of the family Dolichochampsidae. Fossils have been found in the Yacoraite Formation of Argentina and the El Molino Formation of Bolivia of Maastrichtian age. It had a distinctive slender snout. Because the material associated with the specimens is so fragmentary, its relationships with other eusuchians remain unknown. Jouve et al. (2020) assigned Dolichochampsa to Gavialoidea, making it the oldest known South American member of this clade.
The Chacarilla Formation is an Oxfordian to Early Cretaceous geologic formation of the Tarapacá Basin in northern Chile, close to the border with Bolivia. The marine and fluvial formation preserves several dinosaur trackways and has been declared a Natural Sanctuary in 2004.
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. It is the type formation of the Tiupampan South American land mammal age.
Antarctilamna is an extinct genus of Devonian cartilaginous fish originally exemplified by Antarctilamna prisca from South Eastern Australia and Antarctica. The latest occurring described species is Antarctilamna ultima from the Waterloo Farm lagerstätte in South Africa. Antarctilamna has robust ctenacanthid-like spines which lack a deep insertion area, and are borne in front of the first dorsal fin; in addition to distinctive diplodont teeth with small intermediate cusps. Antarctilamna-like spines, known from the Bunga Beds locality in Australia have been ascribed to A. prisca.
The Cuche Formation is a geological formation of the Floresta Massif, Altiplano Cundiboyacense in the Eastern Ranges of the Colombian Andes. The sequence of siltstones, shales, and sandstone beds dates to the Late Devonian and Early Carboniferous periods, and has a maximum thickness of 900 metres (3,000 ft).
The Kirusillas Formation is a Homerian geologic formation of central Bolivia. The formation comprises black shales, overlies the Llallagua Formation and is overlain by the Pampa and Guayabillas Formations. The Kirusillas Formation is laterally equivalent to the Lipeón Formation. The formation is a potential source rock for shale oil and shale gas.
The Catavi Formation is a Pridoli to Emsian geologic formation of northern and central Bolivia. The formation comprises a 456 m (1,496 ft) thick succession of fine-grained, olive to brown sandstones and siltstones, shales and black limestones deposited in a shallow to deep marine environment.
The Gamoneda Formation is an Emsian geologic formation of southern Bolivia. The approximately 340 metres (1,120 ft) thick formation comprises marine micaceous grey siltstones and burrowed grey sandstones and shales.
The Iquiri Formation is an Eifelian to Frasnian geologic formation of central Bolivia. The formation comprises black shales and sandstones.
The El Molino Formation is a Maastrichtian geologic formation pertaining to the Puca Group of central Bolivia. The formation comprises fine-grained sandstones and sandy limestones with stromatolites deposited in a shallow marine to lacustrine environment. The formation has provided fossils of Dolichochampsa minima, and ichnofossils of Ankylosauria indet., Ornithopoda indet., Theropoda indet. and Titanosauridae indet. The tracksite of Cal Orcko is the best known example of the ichnofossil locations of the formation. The ichnofossil of Ligabueichnum bolivianum may be attributed to an ankylosaur. The fossil fish species Dasyatis molinoensis is named after the formation.
The Acacus Sandstone is a geologic formation in the Ghat District, southwestern Libya. The unit preserves fossils dating back to the Llandovery epoch of the early Silurian period.
