http://www.angelfire.com/mi/dinosaurs/dinoscoexist.html "Cretaceous rock is the layer of rock that many geologists say dinosaurs are found in. But they don't have any accurate way of telling how old a layer of rock is (see my page on Carbon dating). They say it is Cretaceous rock only because dinosaurs are in it."
That's ridiculous. They can carbon 14 date any volcanic rocks they find at that level of strata.
