<P>PROBLEM TO BE SOLVED: To clarify the problems of when a meteorite dividing the Rodinia continent (erroneously considering that this continent is the Pangaea continent) falls in the Gulf of Mexico and the Caribbean Sea and when a meteorite extinguishing dinosaurs falls in the Hudson Bay. Ž<P>SOLUTION: Living things begin to move from the sea to the dry land 450 million years ago. Dinosaurs appearing almost 200 million years later reign over the living world of the Earth over for almost more than 160 million years. The Rodinia continent 425 million years ago, the Pangaea continent 250 million years ago, the terrain 94 million years ago, and the current terrain exist. The problems are solved from the two points. The time when the dinosaurs are wiped out is 90 million years ago as shown by a formula of 450 million years-200 million years-160 million years=90 million years. Consequently, it is 425 million years ago when a meteorite falls in the Gulf of Mexico. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
