E. Vlachos note: this collection record actually refers to different collection points across the stratigraphic section of the stratotype of the Los Alamitos Formation in Cerro Cuadrado, published in Andreis 1987, fig. 2. We also have unpublished maps of the different collection points during the different campaigns between 1982 - 1987. We will add the different collection points separately and then we will try to add there the corresponding occurrences.- Los Alamitos vertebrates, hadrosaur layer : Río Negro - ? 11732 11733 11740 13712 30646 75729 SW slope of Cerro Cuadrado, Estancia Los Alamitos, near Arroyo Verde, SE Río Negro province, Argentina
