Amazon Rainforest SA
: There have been several reports over the last couple hundred years of animals which the observers described as igaunodon-like being seen in the Amazon. I, however, highly doubt that there could be dinosaurs in the amazon, and would like to propose a new theory. In South America there evolved a family of birds which were giant carnivores, some reaching almost 10 feet in height. In one of these birds, Titanus walleri, the wings had actually evolved into arms, with three clawed fingers (see picture). What if the "igaunodons" people have seen were really these giant, armed birds? The observer would never think of there being huge birds with arms; he would liken his sighting to a dinosaur.
