How did animals reach their separate parts of the world after the ark, and why are there no fossils along their migration trails?

Their common origin is where the ark settled on the mountains of Ararat in Turkey, the general Armenian area. On the ark you have the first edition of all the animals, including baby dinosaurs, and you only need one pair, because there is a great deal of variation built into the DNA; from one pair of dogs you get everything from a greyhound to a chihuahua, and it happens rather fast. Before the flood there was one land mass, Pangaea, that already had cracks in it. During the flood the water stored under the earth rose up through those cracks under tremendous pressure, hundreds of feet into the atmosphere, which is why it rained for forty days, since today's clouds do not hold enough water to rain that long. As the fissures widened, the land masses separated, and once billions of pounds of earth begin to move they carry enormous momentum that only friction slowly stops, like a train that must brake miles ahead of the station. By the time Noah leaves the ark a year later, the masses are still relatively close together, so the land animals disperse: the bears go north where it is cold, the kangaroos go south, the lions stay near the equator, and each animal moves toward the climate that suits it and away from the others. Meanwhile the crusts keep separating, carrying the animals with them, which is why we find them where we do; and the land masses are still moving today, a couple of millimeters a day, and even the moon is moving away about four centimeters a year. As for whether there was enough water for a worldwide flood, they have found there is four times as much water under the crust and in the mantle as in all the oceans, so there was more than enough.
