Dinosaur Files

What made the earth such a hospitable place for gigantic reptiles during the age of the dinosaurs?

For example...primates arose when forests became dominant...what was going on during the time of the dinosaurs?

1. Your example about primates is wrong. As is your belief in the 'age of the dinosaurs'. Those that think the dinosaurs died out millions of years ago are perhaps unaware of the large amount of evidence indicating that they lived recently alongside man. There are many written accounts and depictions of dinosaurs. http://www.genesispark.org/genpark/ancient/ancient.htm Remember that the word dinosaur was invented in 1841. Before that people used names like dragon. People from all over the world have accounts of dinosaurs: the Chinese who have incorporated it into their lunar calendar, The Welsh who have the dragon in their flag; The account of the Saxon Beowolf; The native american thunderbird; and other stories from many other nations. The Romans even made mosaics of them. Furthermore, dinosaur fossils have even been found containing blood cells - hardly 65 million years old. http://www.googlesyndicatedsearch.com/u/creationontheweb?q=dino+blood&hl=en&lr= But check the evidence for yourself - don't by brainwashed by dogmatic evolutionists who don't want us to think for ourselves :) http://www.creationontheweb.com/content/view/3061
2. Two main things: a higher oxygen level, and a higher global temperature which made plant-life plentiful (think of a much more widespread tropical forest). These two things governed the rise (and eventual fall) of the dinosaurs in Mesozoic. The Mesozoic is divided into three periods: the Triassic, the Jurassic, and the Cretaceous ... each of which began and ended with a mass extinction. The Triassic period followed the most devastating mass-extinction in the history of the earth at the end of the Permian period about 250 million years ago (Mya). This coincides with soil, rock, radiometric evidence of a large drop in oxygen levels, and saw the extinction of 70% of land verterbrate species. The survivors were those that could develop a very efficient respiratory system ... including the ancestors to the dinosaurs. The dinosaurs emerged during the late Triassic, but the really big ones did not appear until the Jurassic following another extinction about 200 Mya (but one not quite as devastating as the P-T extinction). It was during the Jurassic period that we see evidence of soaring oxygen levels, but with a much warmer global temperatures. And it is during the Jurassic that we find the emergence of the really big dinosaurs ... the ancestors of the reptile survivors that had developed extremely efficient respiratory systems now had both soaring oxygen levels and flourishing plant life to support the kind of metabolism needed by large reptilians.
