A major global catastrophe took place when the earth was flooded at the time of Noah, and geological evidence suggests that the continents and oceans underwent massive movements. The large amounts of mud and moving sediment would have provided ideal conditions for fossilisation. Places have been found in the world where large numbers of dinosaur fossils are gathered together in a localised area, suggesting that they got caught up in some sort of sudden global catastrophe. Also there is no certain method of dating fossils (see section on radioactive dating).
According to geologists, the newer life forms are fossilised in the higher and supposedly newer layers of rocks. Look at it another way – in the event of the flood, the mammals would have been more able to run to the mountain tops than the more sluggish reptiles, and the fish would not have climbed the mountains at all!
We are told in Genesis Chapter 1 that God created all living things according to their kinds. This view agrees fully with the fossil record. Billions of fossils have been found and virtually all without exception relate to specific categories of life forms (e.g. fish, reptiles, mammals); even the odd ones that could feasibly belong to an intermediate form can still be categorised one way or another. According to concept of evolution however, life gradually progressed from one form to another. If this were true then we would expect to find plenty of intermediate life forms in the fossil record, and yet this is simply just not the case.
