On this day, 34 years ago, November 17, 1991 (October 12, 1991 in the lunar calendar), the United States discovered the largest skull fossil on earth. On November 17, 1991, American scientists discovered the fossil skull of the Amblyrosed Crocodile along the Amazon River in South America. This carnivore, which lived 8 million years ago, was larger than the dinosaurs 60 million years ago. This suggests that the Crocodile is the largest walking animal on earth. According to the British "Independent" report, Professor Carl Fralay of Overland Park, Kansas, USA, said that the blunt crocodiles are 2-4 meters tall and 12 meters long. Its skull is 1-3 meters long and its weight is estimated to be about 12 tons. It uses its 12-centimeter-long teeth to prey on rodents as large as cattle, as well as birds and turtles.
