The first one seems to be one of those big lizards that run on their hind legs and reported in both North and South America in the drier uplands of the west ("Mini-Rex", "Mountain Boomer" and so on.) This evidently represents a foreign animal, whichever species it represents, because no lizards live in the Altiplano plateau near Lake Titicaca. There are both traditions and reports of the biped lizard types further to the South, in Northern Argentina and in Chile.
