Abstract
El conjunto de afloramientos de 1AAR presenta huellas de dinosaurios
bípedos y cuadrúpedos. Las huellas bípedas se han asociado a icnitas terópodas
y prosaurópodas, mientras que las segundas se asocian a icnitas
prosaurópodas. Cabe la posibilidad de que parte de las icnitas cuadrupedas
sean saurópodas, pero la mala conservación y las condiciones de los afloramientos
no permiten hacer observaciones directas ni apropiadas sobre ellas.
En este trabajo se describen los caracteres determinativos y la posible asignación
de las icnitas.Aunque no es la primera vez que se mencionan huellas
prosaurópodas en AAR, las de estos afloramientos son morfológicamente
diferentes debido probablemente al comportamiento del barro durante la
formación de la pisada
The 1AAR group of outcrops show traces of bipedal and quadrupedal dinosaurs. The bipedal ichnites have been associated with theropod and prosauropod footprints, while the quadrupedal are associated with prosauropod footprints. It is possible that some of the quadrupedal traces were sauropod footprints, but the poor preservation and the outcrop conditions do not allow us direct and appropriate observations of them. Diagnostic characters and the possible attribution of the footprints are described in this paper. Although it is not the first time that prosauropod traces are signaled from the AAR, the footprints of the present outcrops result morphologically different, probably due to reaction of mud during the formation of the ichnite
