PENNSYLVANIAN HETEROCONCHIA (MOLLUSCA, BIVALVIA) FROM THE PIAUI FORMATION, PARNAIBA BASIN, BRAZIL
(Soc Brasileira Paleontologia, 2009-05-01)
Dolostones of the Upper Piaui Formation. Parnaiba Basin, Northern Brazil, record a rich and diversified invertebrate fauna of the Middle Pennsylvanian (Morrowan to Desmoinesian) age. Among bivalves, Heteroconchia is the ...

Late Paleozoic carbonates and glacial deposits in Bolivia and northern Argentina: significant paleoclimatic changes
(Allen Press Inc., 2019)
In Bolivia, a marked climatic paleogradient (from west northwest to south) is visible in the Carboniferous depositional systems. In the northwest is the Pangean trend, a warm-water Pennsylvanian and Permian succession ...
Late Pennsylvanian aridification on the southwestern margin of Gondwana (Paganzo Basin, NW Argentina): A regional expression of a global climate perturbation
(Elsevier Science, 2015-01)
Paleosols of the Paganzo Group preserve a shift from the cool climate of the glaciated high-latitudes of Gondwana to a long-term aridification punctuated by shorter-term fluctuations in moisture regime in the late ...
The Pennsylvanian palynoflora of the Pando X-1 Borehole, northern Bolivia
(Elsevier Science, 2009-11)
Palynological analysis of ten core samples obtained from 867-729 m depth in the Pando X-1 Borehole (11° 36′07″ S, 67° 56′45″ W), northern Bolivia, is presented. Palynomorphs are fairly well-preserved although many contain ...
Combined U-Pb and Lu-Hf isotope study from the Las Lozas volcanics, northwestern Argentina: Evidence of juvenile Cryogenian-derived, lower Pennsylvanian volcanism in western Gondwana
(Pergamon-Elsevier Science Ltd, 2015-04)
Las Lozas volcanic succession, cropping out in the southwestern Puna, Catamarca province, Argentina, consists of an intracontinental volcanic sequence of Carboniferous age. The lavic members are predominantly rhyolites, ...
New U–Pb zircon age for the Pennsylvanian in Argentina: Implications in palynostratigraphy and regional stratigraphy
(Pergamon-Elsevier Science Ltd, 2019-06)
A continuous Pennsylvanian succession belonging to the Agua Colorada and De La Cuesta formations is exposed in the Las Angosturas area (Catamarca Province) of the Paganzo Basin. Glacial, postglacial, fluvial and shallow ...

Pennsylvanian brachiopod, fish and conodont faunas from the Caliza Masiva (San Emiliano Formation) at the Mina Profunda area, Cantabrian Zone, NW Spain
(Elsevier France-Editions Scientifiques Medicales Elsevier, 2020-04)
A rock sample obtained from the Caliza Masiva of the San Emiliano Formation (Bashkirian–early Moscovian) in the Mina Profunda area (NE Villamanín) of the Bodón Nappe (Cantabrian Zone, NW Spain) has yielded numerous brachiopods ...
