Most are aware that the dinosaurs and a moist tropical climate for most of earth's land surface existed possibly 225,000,000 years ago and then suddenly after millions of years at about 65,000,000 years ago all large living creatures(dinosaurs) suddenly became extinct and so did the climate that existed. Also, many scientists and archaeologists believe there was a continental divide(a shifting of tetonic plates) which turned one large land mass on earth into the basic land conformity we have today in the world. I have heard and read many theories of the ice age but it can't account for the enormous destruction and transformation that occurred to life on earth. First, I would like to explore the global tropical climate during the days of the dinosaurs and the giant vegetation for that period. A good reminder of that is on the coast of Maine at and around Kenny Bunkport. All those giant bamboo type petrified trees piled high along the coast line and people everyday walk over them, thinking they are rocks. This is an amazing display of an enormous ancient explosion or land movement. Also, has anyone wondered why the giant vegetation doesn't exist today. We have bamboo and giant redwoods, but they are dwarfed compared to those ancient trees. Also, what ever occurred created enough force to cover the existing vegetation of that time within a very short time frame or natural rot and decay would have taken place. Our oil deposits derived from this action. North of Austin Texas on Interstate 35 are caverns discovered during the inital construction of that highway. They are called InnerSpace Caverns. Many different forms of prehistoric life are found there. These caverns are accessible by a man made entrance. They have found two natural entrances to the caverns that were sealed with mud during a catastrophic event. With all prehistoric species found there it appears that a very quick and violent flood moving millions if not trillions of tons of material had sealed the fate of those animals. Also, with the global positioning system used to locate our moon it shows that the moon is moving away from the earth by about seven inches per year. I am taking a gamble that most readers have played a friendly game of pool or billiards or something similar that requires hitting one hard ball into another. Here is my theory: During pre-dinosaur and existing dinosaur age the Earth was on a wobbly axis and rotated very slowly with considerably less gravity(something close to the moon I would think). That gives us a reason for the tropical climate and large animals and vegetation. Here comes a meteor or small planet on a collision course with earth only it's impact with earth is a glancing blow and not a direct hit. If this occurred on the water side of the earth opposite of the large single land mass, the shock going through the earth's mantle could have caused the land mass to split apart and then the land masses were ravaged by the impending enormous ocean covering event from the impact. I could envision two to five thousand foot tidal waves covering all the continents that are sliding away from the primary(stationary) land mass that did not drift or move(Africa and Europe). This would have definitely covered all the vegetation and dinosaurs leaving only those surviving animals that lived or got to elevations over 6000 feet. Some dinosaurs survived but not for long because the impact would have caused the earth to straighten up on it's axis and increased it's rotational speed creating more gravity. Large animals and large vegetation could not survive the new increased gravitational force. The smaller planet/meteor would have rebounded a short distance from earth and started rotating also. Since, the moon's gravity is much less than ours I would think that that the larger mass of the earth started it rotating, but at a slower speed. This would also suggest the moon was not rotating prior to impact. Now, we know what effects the moon has had on earth in our current time. It is amazing to ponder what effects the moon had on the earth when it was 200,000 miles closer. The ocean waves must have been enormous for millions of years. I don't believe this impact would have sent the earth into the ice age if the initial impact occurred in the oceans on the opposite side of the earth's land mass. I also believe that the moon after impact with it's new gravitational influence on the earth and it's closer position to earth, would have created an atmosphere with a large electro-magnetic influence and helped influence the development/evolution of life on earth that was more neural electrically enhanced.
