| dc.description | Se presentan nuevos restos provenientes de estratos campaniano-maastrichtianos de la Formacion Alien, en Salitral Ojo de Agua (Rio Negro, Argentina), los cuales son asignables a Alvarezsauridae indet. Este ciado de pequenos teropodos celurosaurios es conocido de estratos de edad similar en Mongolia y de sedimentitas mas antiguas (de edad turoniana y coniaciana) en Argentina. De este modo, el material que aqui se informa extiende el registro temporal de los alvarezsauridos del Hemisferio Sur hasta el Cretacico Tardio alto. Los huesos reportados estaban asociados a cascaras de huevo de la oofamilia Elongatoolithidae, los cuales son actualmente atribuidos a Theropoda. | es-ES |
| dc.description | We present new remains from the Cam-panian-Maastrichtian beds of the Alien Formation, in Salitral Ojo de Agua (Río Negro, Argentina), which are assignable to Alvarezsauridae indet. This clade of small coelurosaurian theropods is known from strata of similar age in Mongolia, and from older sediments (Turonian and Coniacian in age) in Argentina. Thus, the material presented here extends the temporal record of the alvarezsaurids from the Southern Hemisphere up to the Latest Cretaceous. The fossil bones reported were associated to eggshells of the oofamily Elongatoolithidae, which are actually attributed to Theropoda. | en-US |
