The study of Archaeofauna at Middle Holocene in Aep-1 rockshelter, Santa Cruz, Argentina: Taphonomic implications
(Pergamon-Elsevier Science Ltd, 2011-11)
The taphonomic history of the Middle Holocene archaeological component at the AEP-1 site was studied based on the analysis of bone modifications of the archaeofaunistic assemblage and the features of the geological matrix. ...
Formative pre-Hispanic agricultural soils in northwest Argentina
(Cambridge University Press, 2011-01)
Our study area is from an early agricultural archaeological site named "El Tolar" (1st to 9th century AD), located in Tafí Valley (Tucumán, northwest Argentina). The objective was to identify geochemical signatures generated ...

100 Ma sweat bee nests: Early and rapid codiversification of crown bees and flowering plants
(Public Library of Science, 2020-01)
100 Ma sweat bee nests reported herein are the oldest evidence of crown bees. A new phylogeny for short-tongued bees, calibrated with these nests dated with 40Ar/39Ar, attests for the first time for a late Albian rapid ...
An overview of hymenopteran cocoons as a tool to interpret ichnospecies of Fictovichnus (Pallichnidae) and other fossil cocoons of wasps
(Society for Sedimentary Geology, 2019-11)
Hymenopteran cocoons are complex structures constructed from silk by larvae and exhibit a wide range of morphologies, compositions, and textures. The recognition of the most relevant characters of modern cocoons is important ...
Distinguishing similar volcanic source areas from an integrated provenance analysis: Implications for foreland Andean basins
(Society for Sedimentary Geology, 2013-03-24)
The Mata Amarilla Formation marks the onset of the foreland stage of the Austral basin, which is composed of mostly nonmarine and littoral siliciclastic sediments, thus providing an opportunity to study the detrital record ...
Allogenic controls on the fluvial architecture and fossil preservation of the Upper Triassic Ischigualasto Formation, NW Argentina
(Elsevier Science, 2017-12)
The Upper Triassic Ischigualasto Formation in NW Argentina was deposited in a fluvial system during the synrift filling of the extensional Ischigualasto-Villa Unión Basin. The expansive exposures of the fluvial architecture ...
Sedimentology and paleoecology of a diverse Early Jurassic tetrapod tracksite in Lesotho, southern Africa
(Society for Sedimentary Geology, 2009-10)
An Early Jurassic tetrapod tracksite in the upper Elliot Formation at Moyeni, southern Lesotho, displays a variety of trackways attributed to large- and medium-sized theropod (Neotrisauropus-type) and ornithischian ...
Tectonostratigraphic significance of the neogene sedimentary record of northwestern Austral-Magallanes Basin, Argentinean Patagonia
(Asociación Argentina de Sedimentología, 2019-05)
Despite their geodynamic significance, the stratigraphy and paleoenvironments of the lower-middle Miocene clastic deposits, genetically related to subductiondriven lithospheric processes at the latitude of the Chile Triple ...
PALEOCLIMATIC CONTROLS ON STABLE OXYGEN AND CARBON ISOTOPES IN CALICHE OF THE ABO FORMATION (PERMIAN), SOUTH-CENTRAL NEW-MEXICO, USA
(Sepm-soc Sedimentary Geology, 1991-07-01)
The stable oxygen and carbon isotopic composition of caliche in fluvial and supratidal rocks of the Abo Formation (Permian), south-central New Mexico, is controlled by palecoclimate and depositional environment. Fluvial ...
