But I think you're right, fish a reptiles have amazing strength, or say ants compared to their body weight. However, a working visual peptide of a (theoretical) dinosaur has been inferred, using analytical phylogenetic reconstruction methods on gene sequences of still-living related species (reptiles and birds) (Chang et al., 2002).

The widespread application of cladistics, which rigorously analyzes the relationships between biological organisms, has also proved tremendously useful in classifying dinosaurs, which are still known from a spotty fossil record. The superorder or clade "Dinosauria" was formally named by the English scientist Richard Owen in 1842. The term is a combination of the Greek words deinos ("terrible" or "fearfully great" or "formidable") and sauros ("lizard" or "reptile") Prehistoric Life (Eyewitness Lvg Earth Video) download epub.

Second, one must recognize that whereas the Bible was completed 1,900 years ago and was translated fully into English by 1535 (by Miles Coverdale), the English word “dinosaur” was not coined until 1842—more than 300 years after the first complete English translation of the Old and New Testaments online.

The real question then, is not, “Why don’t we find dinosaur and human fossils together?,” but, “Where are all of the human fossils?” Simply because human fossils apparently have not been found with dinosaur fossils does not make the case for the coexistence of dinosaurs and humans any less credible ref.: Dinosaurs 2013 Calendar Dinosaurs 2013 Calendar.
