Uh-oh, you asked for it... :-)
[Morris & Whitcomb's 1961 classic, The Genesis Flood]'s primary thesis is that the appearance of evolution in the fossil record is an accidental artifact of sedimentation. When a great flood destroyed most of the life on planet earth, say the YECs, those living things that could not escape to higher ground wound up near the bottom of the sediment. These are the rocks that earth scientists regard as being from the oldest geological ages. The young-earth creationists contend that those animals that could swim or float or climb most effectively wound up near the top, in so-called recent ages. ...Is there a chance that these "flood geologists" are genuine, sincere scientists? Is it possible that they are lonely pioneers laboring in a great and noble tradition of scientific outcasts, fighting for respectability and ultimately for proof of their ideas? I don't think so; and I say that not to make a character judgement, but as an evaluation of scientific behavior. If they really believe in the validity of their interpretations of fossil history, they should be charging ahead to exploit a great scientific opportunity: the coprolite.
Coprolites are fossilized feces. Over the years, paleontologists have found thousands of these objects, including a notable one described from Nature magazine in 1998 with the alluring title, "A King-Sized Theropod Coprolite." The size and location of the object indicate it was produced by a meat-eating dinosaur, probably Tyrannosaurus rex. This coprolite was packed with large fragments of partially digested bone. Other coprolites are available, if our YEC colleagues prefer, from ancient mammals, plesiosaurs (swimming reptiles), and even from insects.
For young-earth creationists, these remains present a stunning opportunity to validate their ideas. All they would have to do is pick through these objects and find evidence of a single contemporary organism. Seeds or microscopic pollen grains from modern plants would do the trick in the case of herbivorous dinosaurs. If they could just find a couple of tuna bones in the stomachs of those plesiosaurs, they'd stand the geological world in its head by demonstrating that creatures of the "ancient" and the modern worlds existed side by side before the flood, as they have always maintained. The young-earth creationists make no such effort. They keep themselves carefully aloof from any hands-on contact with genuine evidence, such as the fact that the digestive systems of the plesiosaurs are filled with ammonites, extinct mollusks from the same geological age.
