Traces within traces: holes, pits and galleries in walls and fillings of insect trace fossils in paleosols
(Universidad de Barcelona, 2003-12)
Fossil insect nests with constructed walls (ichnogenera Uruguay ROSELLI 1938, Palmiraichnus ROSELLI 1987, Rosellichnus GENISE and BOWN 1996), as well as fossil brood masses from dung beetles (Monesichnus ROSELLI 1987) often ...
Spirodesmos milanai n. isp.: A shallow-water spiral trace fossil from the Cambrian of the Eastern Cordillera, northwest Argentina
(Taylor & Francis, 2005-04)
A new ichnofossiliferous locality in Salta Province (northwest Argentina) contains an association with numerous irregular spiral traces assigned to Spirodesmos milanai n. isp., in mature sandstones and quartzites with ...
Application of vertebrate trace fossils to palaeoenvironmental analysis
(Elsevier Science, 2015-12)
This is a review of the main uses of vertebrate trace fossils, ichnofabrics and ichnofacies in the palaeoenvironmental analysis of sedimentary sequences. The article accounts for the significant developments produced in ...
Trace fossils of cicadas in the Cenozoic of Central Patagonia, Argentina
(Wiley Blackwell Publishing, Inc, 2008-03)
Hemispherical pan or dish-shaped trace fossils from the Cenozoic of the Central Patagonia are attributed to the burrowing action of cicadas. A new ichnotaxon, Feoichnus challa igen. et isp. nov. is characterized by its ...
Palaeonvironmental and palaeoecological significance of flamingo-like footprints in shallow-lacustrine rocks: An example from the Oligocene-Miocene Vinchina Formation, Argentina
(Elsevier Science, 2012-01)
This article describes the lacustrine trace-fossil assemblage of the Late Oligocene-Early Miocene Vinchina Formation of northwest Argentina. The thick (> 5000. m) continental succession of the formation is essentially ...
Three-dimensionally integrated trace fossils from shallow-marine deposits in the Lower Cretaceous of the Neuquén Basin (Argentina): Hillichnus agrioensis isp. nov.
(University of Warsaw. Institute of Geology, 2010-03)
A complex trace fossil that requires a three-dimensional (3D) reconstruction is described and interpreted. The specimens studied are assigned to a new ichnospecies (Hillichnus agrioensis) of Hillichnus Bromley et al., 2003. ...
Paleoecologic trends of Devonian Malvinokaffric fauna from the Paraná Basin as evidenced by trace fossils
(2021-08-01)
The Malvinokaffric Realm is an endemic paleogeographic region that inhabited Gondwanan high latitude seas during Early-Middle Devonian times. The causes for the collapse of this fauna are still debated but seem to be related ...
Cruziana- and Rusophycus-like traces of recent Sparidae fish in the estuary of the Piedras River (Lepe, Huelva, SW Spain)
(Elsevier, 2015-12)
Modern fish are able to produce a plethora of different traces (both bioturbation and bioerosion structures) according to several behaviours, yet only five ichnotaxa have been interpreted as produced by the activity of ...
Tasselia ordamensis: a biogenic structure of probable deposit-feeding and gardening maldanid polychaetes.
(Elsevier Science, 2010-06)
The internal structure and growth direction of well-preserved Tasselia ordamensis specimens from the Upper Cretaceous–Cenozoic of Antarctica and Tierra del Fuego are not compatible with its current interpretation as a ...
The changing face of the deep: Colonization of the Early Ordovician deep-sea floor, Puna, northwest Argentina
(Elsevier Science, 2009-09)
An Upper Tremadocian deep-sea ichnofauna from the Chiquero Formation of Puna, northwest Argentina, represents a link between Ediacaran and Cambrian microbial-mat dominated ecosystems and younger Ordovician deep-marine ...
