It is harder to argue remnant populations of Dinosaurs surviving in Montana and elsewhere to tens of thousands years ago, but even granted that assumption, how does that disprove evolution?
What I am saying is We know that many species have both died out and survived from prehistory, how does the fact the we could be mistaken on the dates of extinction for some argue in favor creationism.
The dates given for prehistory have always been estimates stated as possibilities arrived at by the best information available. New discoveries, techniques and improved basic understanding will continue to refine and occasionally rewrite some of these dates because we have so much left to learn. One thing that can not be logically ignored is that both life and planet Earth have a very long and rich prehistory.
or that's how I feel about it anyway
