Tetrapod burrows from the Middle–Upper Triassic Chañares Formation (La Rioja, Argentina) and its palaeoecological implications
(Elsevier Science, 2018-05)
We describe tetrapod burrows from the uppermost Middle–lower Upper Triassic (latest Ladinian–early Carnian) Chañares Formation (Ischigualasto-Villa Unión Basin), La Rioja Province, northwestern Argentina. The burrows were ...
Monotypic colonies of Clathropteris meniscioides (Dipteridaceae) from the Early Jurassic of central Patagonia, Argentina: implications for taxonomy and palaeoecology
(E Schweizerbartsche Verlags, 2016-09)
A collection of over 130 specimens of the fossil dipterid fern Clathropteris meniscioides (Brongn. 1825) Brongn. 1828 from in-situ colonies in the Lower Jurassic of Chubut, Argentina, provides evidence for population-level ...
Jurassic neoselachian sharks from the Mt Nerone Pelagic Carbonate Platform (Umbria-Marche Apennine, Italy): a further constrain for the palaeoecology related to PCP systems
(Taylor & Francis Ltd, 2019-12)
The Mt Nerone area hosts a Jurassic-Cretaceous Pelagic Carbonate Platform (PCP)-basin succession in the Umbria-Marche Domain (Central Italy). Despite being studied thoroughly on sedimentological and geological aspects, ...
The lycophytes of the La Golondrina Formation (Permian), Santa Cruz Province, Argentina: Systematic revision, biostratigraphy and palaeoecology
(Taylor & Francis, 2012-12)
The Permian lycophytes of the La Golondrina Formation (Santa Cruz province, Argentina) have remained unstudied for almost 50 years. This study reviews material described by Archangelsky in 1960 and increases the representation ...
