Mammoth drawings are not unusual in such cave art, but the depiction of an apparent theropod dinosaur is remarkable. In BC, under the reign of King Nebuchadnezzar, a Babylonian artist was commissioned to shape reliefs of animals on the structures associated with the Ishtar Gate.

Carbon 14 is used for this example: This nullifies the carbon method as well as demonstrating that the earth is less than 10, years old. The above is offered as a simple fact of research. Knowing how faulty creationist "facts" can be, let's do a little research of our own.
Ancient Dinosaur Depictions
Acknowledgements Introduction his document discusses the way radiometric dating and stratigraphic principles are used to establish the conventional geological time scale. It is not about the theory behind radiometric dating methods, it is about their application, and it therefore assumes the reader has some familiarity with the technique already refer to "Other Sources" for more information. As an example of how they are used, radiometric dates from geologically simple, fossiliferous Cretaceous rocks in western North America are compared to the geological time scale. To get to that point, there is also a historical discussion and description of non-radiometric dating methods.
The other groups mentioned are, like dinosaurs and pterosaurs, members of Sauropsida the reptile and bird clade , except Dimetrodon which is a synapsid. Definition Triceratops skeleton, Natural History Museum of Los Angeles County Under phylogenetic nomenclature , dinosaurs are usually defined as the group consisting of the most recent common ancestor MRCA of Triceratops and Neornithes , and all its descendants. In traditional taxonomy, birds were considered a separate class that had evolved from dinosaurs, a distinct superorder. However, a majority of contemporary paleontologists concerned with dinosaurs reject the traditional style of classification in favor of phylogenetic taxonomy; this approach requires that, for a group to be natural, all descendants of members of the group must be included in the group as well.
