| dc.description | The characteristics of dinosaur footprints (Baños del Flaco Formation) and also the microfacies of the associated beds were analyzed. Through the footprints it was possible to interpret aspects of the dinosaur's behavior, which were very similar to the extant faunas from the African savannah, with preferred progression parallel to the margin of the water body (northwest-southeast). The ichnocoenosis corresponds to ornithopod theropodsauropod (OTS) and it is related, in general aspects, to the Brontopodus ichnofacies. It is inferred that the depositional environment corresponded to a lagoon shore of a shallow carbonate platform from tropical to subtropical climate. Bioherms indicate the local position of the sea. The ichnites are located on the continental shore of the lagoon and their preservation was due to the deposition of a layer of pyroclastic material that quickly buried them. | en-US |
| dc.description | Se realizo un estudio de las caracteristicas de las trazas de dinosaurios de la Formacion Banos del Flaco, incluyendo las microfacies de las capas que las contienen. Se infiere que el ambiente de deposicion correspondia a la ribera de una laguna asociada a una plataforma calcarea somera, clima tropical a subtropical, existiendo biohermes que indican la posicion local del mar. El analisis paleoicnologico permitio conocer aspectos del comportamiento de los dinosaurios que originaron las pistas, el que es muy similar al de la fauna actual en la sabana africana. Las improntas indican un modo preferente de caminata, desplazandose paralelamente al margen del paleocuerpo de agua (noroeste-sureste). La icnocenosis determinada corresponde a ornitopodo-teropodo-sauropodo (OTS) y se relaciona en aspectos generales a la icnofacies Brontopodus. Las icnitas se encuentran en el sector del borde continental de la laguna costera y su preservacion se debio a la deposicion de una capa de material piroclastico que las sepulto. | es-ES |
