Early Cretaceous bivalves of the Neuquén Basin, west-central Argentina: Notes on taxonomy, palaeobiogeography and palaeoecology
(John Wiley & Sons Ltd, 2007-04)
This paper provides an updated taxonomic inventory of the bivalve fauna collected in the Pilmatué Member of the Agrio Formation of the Neuquén Basin, west-central Argentina, places the fauna in its palaeobiogeographic ...
A Holocene history of monkey puzzle tree (pehuén) in northernmost Patagonia
(Wiley Blackwell Publishing, Inc, 2021-04)
Aim: Although it is established that climate and fire have greatly influenced the long-term ecosystem dynamics of Patagonia south of 40°S, the environmental history from northernmost Patagonia (37–40°S), where endemic and ...
Shell bone histology of the long-necked chelid yaminuechelys (Testudines: Pleurodira) from the late cretaceous—early palaeocene of patagonia with comments on the histogenesis of bone ornamentation
(Springer, 2016-02)
Yaminuechelys is a long-necked chelid turtle whose remains have been recovered from outcrops of the Santonian-Maastrichtian and Danian of SouthAmerica.With the purpose of providing data about shell sculpturing origin and ...
Asteroid trace fossils from Lower Cretaceous shallow- to marginal-marine deposits in Patagonia
(Academic Press Ltd - Elsevier Science Ltd, 2019-01)
Most stellate trace fossils of the ichnogenus Asteriacites are attributed to asterozoan producers in general and the majority is the result of the work of ophiuroids. The fossil record of asterozoans is scarce in South ...
First remains of neoginglymodian actinopterygians from the Jurassic of Monte Nerone area (Umbria-Marche Apennine, Italy)
(Società Geologica Italiana, 2019-02)
Since the early nineteenth century, the structural high of Mt. Nerone in the Umbria-Marche-Sabina Domain (UMS - Central/ Northern Apennines, Italy) attracted scholars from all over Europe due to the wealth of fossil fauna ...
Rodents from Botardo-D and the Miocene-Pliocene transition in the Guadix-Baza Basin (Granada, Spain)
(Springer, 2020-09)
The rich small-mammal record from the Guadix-Baza Basin (Granada, southern Spain) provides a rather continuous biostratigraphic sequence from the late Miocene to the middle Pleistocene. However, the earliest Pliocene is ...
The osteoderm microstructure in doswelliids and proterochampsids and its implications for palaeobiology of stem archosaurs
(Polish Academy of Sciences. Institute of Paleobiology, 2017-10)
Osteoderms are common in most archosauriform lineages, including basal forms, such as doswelliids and proterochampsids. In this survey, osteoderms of the doswelliids Doswellia kaltenbachi and Vancleavea campi, and ...
New insights into postglacial vegetation dynamics and environmental conditions of Península Avellaneda, southwest Patagonia, revealed by plant macrofossils and pollen analysis
(IMCG and IPS, 2018-09)
Reconstruction of the history of past events becomes more objective when considering an increased number of possible indicators. Combining plant macrofossil analysis with pollen analysis has the potential to give a more ...
Xiphosurid trackways in a Lower Cretaceous tidal flat in Patagonia: Palaeoecological implications and the involvement of microbial mats in trace-fossil preservation
(Elsevier Science, 2013-04)
Lower Cretaceous trackways assignable to xiphosurids were recently found in tidally influenced marginal-marine deposits of the Agrio Formation (Patagonia, Argentina). The aim of this paper is to describe these trace fossils ...
Asthenopodichnium in fossil wood: Different trace makers as indicators of different terrestrial palaeoenvironments
(Elsevier Science, 2012-12)
The ichnospecies Asthenopodichnium xylobiontum comprises U-shaped traces in wood, usually attributed to the activity of mayfly nymphs (Insecta, Ephemeroptera), which indicate the presence of freshwater palaeoenvironments. ...
