I will post a couple of posts on this topic
One of the things which disproves the global flood are the minor normal activities of life and living which are abundantly clear in the fossil record. Today we will discuss coprolites or fossilized feces.
Coprolites comes from the Greek word, kopros, meaning dung. We find lots of dung in the fossil record and it says many things about the global flood and its impossibility. First, it says that the world could not be flooded by water all the time, because the animals would not be able to find food and after about 5 days, most animals would not have anything left in their digestive tracks. This means that as the flood went on, from the time when the Cambrian strata were deposited, on up to the Permian (half way through the flood) and into the Cretaceous and Tertiary (late in the flood deposition), there should be no vertebrate dung because the world had been flooded for more than 6 months by then. To find coprolites in the later sediments of the flood, means that the animal ate within 5 days of when he eliminated.
Modern examples of the speed of digestion are many. Take a cow. His digestion time takes 5 days (120 hours) (http://www.producer.com/articles/20...010201ls02.html). Humans can move food through the system in 12-72 hours depending on the food. In smaller animals, like mice, birds etc. the need for large inputs of food energy means short times in the digestive tract and thus there are shorter times between eating and excreting. The reason I am discussing how long it takes to move food through the digestive tracts is to time the last meal by the animals who left coprolites in the fossil record. Clearly, it is a matter of days between the last meal and the time when excretion of the dung became necessary.
Creationists have ignored this aspect of coprolite formation. They have tried to claim that if not for rapid burial, the coprolites would not be preserved. Daniel Woolley, in Fish preservation, fish coprolites and the Green River Formation TJ 15(1):10511, 2001 said:
Finally, the models cannot account for why large numbers of fish suffocated quickly, or how fish coprolites were preserved in abundance. Coprolites are statistically the most significantly factor correlated with fossil fish preservation in the Green River Formation. New experimental evidence on the faeces of modern fish show that faeces must be buried in less than 24 hours if they are to be preserved as coprolites in the fossil record. http://www.answersingenesis.org/hom...green_river.asp
He then goes on to claim that experiments with fish dung in an oxygenated aquarium proves that no fish dung can be preserved under any conditions. Given that his experiment doesnt match natural conditions, it is irrelevant. We will come back to the issue of how dung is fossilized. It just takes the correct conditions.
Other creationist writers have dealt inconsistently with coprolites in the fossil record. Sarfatti claims that dino coprolites prove that carnivory was present at the time of Noahs flood but inconsistently doesnt give a single thought to the fact that dinosaur dung means that the animal ate within a few days of letting loose with that big one. He writes:
Fossils of dinosaur bones with tooth marks and dinosaur coprolites (fossilized dung) with the ground-up bones of other dinosaurs are good evidence that carnivory was well established by Noahs Flood. http://www.answersingenesis.org/doc...529charisma.asp
The criticism above is true because dinosaurs dont appear in the fossil record in the Triassic around 230-240 million years ago. This is after the deposition of several thousand feet of Paleozoic strata. The Texas Gulf coast has numerous Mesozoic dinosaur tracks and they rest on at least 15,000 feet of sediment from the Paleozoic, where no dinos are to be found. And no dino coprolites are to be found. One must ask if the dinosaurs were constipated for the first six months of the flood.
Donald DeYoung does the same thing Sarfatti does. He too says things about dinosaur coprolites but then ignores the implication to the flood. DeYoung writes:
For herbivores, the dinosaur dung is usually a rounded mass and varies from pebble-to
basketball-sized. Herbivore droppings with broken-up pieces of conifers have been found at a site in Montana called the Two Medicine Formation. These particular remains are honeycombed with burrows made by dung beetles that scavenged the droppings while they were still fresh. The dinosaur-era beetles conflict with the usual evolutionary story, in which dung-eating beetles evolved long after dinosaur extinction. Coprolites from carnivorous or omnivorous dinosaurs are rarely found. A fossilized dropping found in Canada in 1997 contained 200 small bone fragments from other dinosaurs." Donald B. DeYoung, "Dinosaurs and Creation," (Grand Rapids: Baker Book House, 2000), p. 93-94
The almost laughable thing about this quotation is that it takes some time for the dung-beetles to find the dung and then make burrows into it. Dung beetles also dont work underwater so this was a subaerial excavation project on their part. This data, presented by DeYoung with a straight face, proves conclusively that the area of this dung was above water during this time. But this time is supposedly when the global flood was taking place and all the earth was covered with water to at least 15 cubits.
But the idea that there was a global flood takes an even bigger hit when one considers that tiny animals like ophiomorpha line their burrows with fecal pellets. They eat as they burrow through the sediment so the time between ingestion and excretion is short. This is a common practice.
"Typical dwelling traces include: Skolithos (a simple, unpaired pipe), Ophiomorpha (lined with faecal pellets - which determine a nodular outer surface to the burrow - usually associated with crustaceans), Teredolites (bivalve borings cut into driftwood),
and Gastrochaenolites (bivalve borings cut into firm or rock substrates)." http://www.ucl.ac.uk/geolsci/edu/ug...ssils/morph.htm

Here is a picture of an ophiomorpha burrow.
The rough texture of the walls of this burrow are where the fecal pellets used to be. The animal cant do this instantly. The sand had to have been deposited and then the animal burrowed (he cant burrow before the sand is deposited) and while burrowing must excrete numerous fecal pellets and this cant be instantaneous either.
One can see the fecal deposits better on this orphiomorpha burrow from the North Sea. It is from Martin, M. A., and J. E. Pollard, 1996. "The Role of Trace Fossil (Ichnofabric) analysis in the Development of Depositional Models for the Upper Jurassic Fulmar Formation of the Kittiwake Field (Quadrant 21 UKCS)," in Andrew Hurst et al, editors, Geology of the Humber Group: Central Graben and Moray Firth, UKCS, Geological Society Special Publication No. 114, (London: The Geological Society), Fig 6d, p. 176
Fecal pellets also are found in the burrows of larger animals. In the Triassic of South Africa, there are burrows made by therapsids which are on the line to mammals. Groenewald et al write:
The burrow system described above from Locality 1 is totally devoid of fossil material. In contrast, a very similar but more poorly preserved burrow complex at Locality 2 contains partial or complete articulated skeletons of 20 individuals of the therapsids Trirachodon (cf. NMQR 3278-3296). Articulated skeletons, typically found encased in calcareous nodules, are partly curled-up in the terminal chambers, with the skulls facing toward the burrow tunnels. Gideon H. Groenewald, Johann Welman, James A. MacEachern, Vertebrate Burrow Complexes from the Early Triassic Cynognathus Zone (Driekoppen Formation, Beaufort Group) of the Karoo Basin, South Africa, , Palaios, 16(2001):148-160, p. 153
We know three things about these burrows. The therapsids couldnt burrow until after the sediment was deposited and two, they were above water because the animals are airbreathing. We also know that several thousand feet of sediment exists below these. There is at least 2000 feet of Dwyka tillites, 6500 feet of Ecca Series sediments which have lots of coal, and then comes the Beaufort Group where the burrows are found.(Haughton,1963. Stratigraphic History of Africa South of the Sahara, p. 200-204) Thus these fossils must be late in the flood or at least in the middle. Yet there they are, burrowing in sediments above the water line and they were pooping in their burrows:
Coprolites occur within some of the casts. Gideon H. Groenewald, Johann Welman, James A. MacEachern, Vertebrate Burrow Complexes from the Early Triassic Cynognathus Zone (Driekoppen Formation, Beaufort Group) of the Karoo Basin, South Africa, , Palaios, 16(2001):148-160, p. 154
All of that takes time.
And consider a fossil from my personal collection, a turtle coprolite from the Eocene from Betsiboka, Madagascar.
This coprolite, from my personal fossil collection, was deposited by a turtle in Eocene rocks. Geology says these rocks are 38-55 million years old. The coprolite today is rock-hard and has no smell. It is the mineralized poop from an Eocene turtle. How do we know it is turtle poop? Because even today, in Betsiboka, Madagascar where this was found, turtles come ashore to lay their eggs, they leave such deposits (only a wee-bit fresher) than what you see above.
Now, how do we know that this feces was not deposited during a global flood? Any guesses from the young-earth creationists? It is easy. The coprolite, which today is petrified rock, dried out prior to when it was fossilized. You can see the cracks which formed in the soft poop when it dried out. One can see this phenomenon occasionally in dog feces as they dry but not when the feces are fresh.
Now, the real question for the young-earth creationists is, what were turtles doing coming ashore during the global flood, when there wasn't supposed to be any land? If the feces were deposited in the ocean, it would not have the desiccation cracks in it because it couldn't have dried out. The turbulence of the flood waters would most likely have distorted or even dissolved the feces as it was swept against rocks and other objects by the flood currents. The fact that this feces simply dried out and was then petrified argues strongly against the global flood being responsible for these rocks.
For these turtle-fouled Eocene rocks and younger rocks which lie above them, these facts require that they are at least post flood. One can follow the Eocene rocks from Madagascar around Africa and Eurasia and across to India. In the Ocean the link is unbroken. The thickness of the rocks equal in age or younger (Post Paleocene) offshore India reaches 15 kilometers in thickness (see Curiale et al, AAPG86(2002):4:636). Thus the young-earth creationist, if he/she decides that the sediments I am speaking of are post-flood, must then account for 15 kilometers of post flood sediments offshore India. This is 50,000 feet of sediment. The young-earth creationist must ask himself how it is possible to non-catastrophically erode and deposit that much sediment within the past few thousand years. Clearly this is a difficulty. On the other hand if the young-earth creationist thinks that the sediments are flood sediments, they must explain how the turtles found dry land in the middle of the flood, so that lots of feces could be deposited and then have the time to dry out.
