Petrographic analysis of crowded Rosselia ichnofabrics from the Tremadocian of Northwestern Argentina: Ethologic meaning and diagenesisAnálisis petrográfico de icnofábricas atestadas de Rosselia pertenecientes al Tremadociano del Noroeste Argentino: significado etológico y diagénesis
(Asociación Geológica Argentina, 2020-09)
Se estudiaron Rosselia socialis de la Formación Áspero (Ordovícico), donde forman icnofábricas densas, para explorar su marca sedimentológica y diagenética. Estas icnofábricas son descriptas por primera vez en estratos ...
Estudio quimiométrico preliminar de diagénesis ósea en Cinodontes del triásico temprano de Mendoza, ArgentinaPreliminary Chemometric Study of Bone Diagenesis in Early Triassic Cynodonts from Mendoza, Argentina
(Asociacion Paleontologica Argentina, 2013-07)
Los terápsidos no-mamaliformes dominaron los ecosistemas terrestres durante el Paleozoico Tardío–Mesozoico Temprano. Los cinodontes han sido estudiados desde una perspectiva taxonómica, osteológica y morfológica. Sin ...
Chemometric study of the preservation modes of Athabaskia anax (Trilobita, Cambrian Precordillera, Mendoza, Argentina): Implications for taxonomy
(Elsevier, 2021-08)
Selected pygidia of the middle Cambrian corynexochid trilobite Athabaskia anax (Walcott 1916) from the Miaolingian Series of San Isidro (Precordillera, Mendoza, Argentina) are analyzed for the first time using scanning ...
Recording of climate and diagenesis through sedimentary DNA and fossil pigments at Laguna Potrok Aike, Argentina
(Copernicus Publications, 2016-04)
Aquatic sediments record past climatic conditions while providing a wide range of ecological niches for microorganisms. In theory, benthic microbial community composition should depend on environmental features and geochemical ...
Paleometry as a key tool to deal with paleobiological and astrobiological issues: some contributions and reflections on the Brazilian fossil record
(Cambridge Univ Press, 2019-12-01)
Investigations into the existence of life in other parts of the cosmos find strong parallels with studies of the origin and evolution of life on our own planet. In this way, astrobiology and paleobiology are married by ...
Tracing Biosignature Preservation of Geothermally Silicified Microbial Textures into the Geological Record
(Mary Ann Liebert, 2015-10)
New Zealand and Argentine (Late Jurassic-Recent) siliceous hot-spring deposits (sinter) reveal preservation pathways of environmentally controlled, microbe-dominated sedimentary facies over geological time scales. Texturally ...
