Uh......Dinosaurs are in The Book of Job. God himself decribes in detail animals that we call Apatasaurus and Plesiasaurus.
Not to mention.... science says that DNA is completely gone after 10000 years. So then why do we have Dinosaur DNA? It's broken down DNA ,but alot of it's there for us to see.
(Sigh) We have what appears to be mineralized dinosaur soft tissue. However, we have not discovered any DNA in such tissue.
