Where were all the fossilized animals when they were alive? Schadewald [1982] writes:
"Scientific creationists interpret the fossils found in the earth's rocks as the remains of animals that perished in the Noachian Deluge. Ironically, they often cite the sheer number of fossils in 'fossil graveyards' as evidence for the Flood. In particular, creationists seem enamored by the Karroo Formation in Africa, which is estimated to contain the remains of 800 billion vertebrate animals (see Whitcomb and Morris, p. 160; Gish, p. 61). As pseudoscientists, creationists dare not test this major hypothesis that all of the fossilized animals died in the Flood.
"Robert E. Sloan, a paleontologist at the University of Minnesota, has studied the Karroo Formation. He asserts that the animals fossilized there range from the size of a small lizard to the size of a cow, with the average animal perhaps the size of a fox. A minute's work with a calculator shows that, if the 800 billion animals in the Karoo formation could be resurrected, there would be twenty-one of them for every acre of land on earth. Suppose we assume (conservatively, I think) that the Karroo Formation contains 1 percent of the vertebrate [land] fossils on earth. Then when the Flood began, there must have been at least 2100 living animals per acre, ranging from tiny shrews to immense dinosaurs. To a noncreationist mind, that seems a bit crowded."
A thousand kilometers' length of arctic coastal plain, according to experts in Leningrad, contains about 500,000
tons of tusks. Even assuming that the entire population was preserved, you seem to be saying that Russia had wall-to-wall mammoths before this "event."
Even if there was room physically for all the large animals which now exist only as fossils, how could they have all coexisted in a stable ecology before the Flood? Montana alone would have had to support a diversity of herbivores orders of magnitude larger than anything now observed.
Where did all the organic material in the fossil record come from? There are 1.16 x 1013 metric tons of coal reserves, and at least 100 times that much unrecoverable organic matter in sediments. A typical forest, even if it covered the entire earth, would supply only 1.9 x 1013 metric tons. [
Ricklefs, 1993, p. 149]
How do you explain the relative commonness of aquatic fossils? A flood would have washed over everything equally, so terrestrial organisms should be roughly as abundant as aquatic ones (or more abundant, since Creationists hypothesize greater land area before the Flood) in the fossil record. Yet shallow marine environments account for by far the most fossils.

8. Species Survival and Post-Flood Ecology
"He blotted out every living thing that was upon the face of the ground," the Bible says (
Gen 7:23). If the Flood was as described, that must have been an understatement.
How did all the modern plant species survive?
- Many plants (seeds and all) would be killed by being submerged for a few months. This is especially true if they were soaked in salt water. Some mangroves, coconuts, and other coastal species have seed which could be expected to survive the Flood itself, but what of the rest?
- Most seeds would have been buried under many feet (even miles) of sediment. This is deep enough to prevent spouting.
- Most plants require established soils to grow--soils which would have been stripped by the Flood.
- Some plants germinate only after being exposed to fire or after being ingested by animals; these conditions would be rare (to put it mildly) after the Flood.
- Noah could not have gathered seeds for all plants because not all plants produce seeds, and a variety of plant seeds can't survive a year before germinating. [Garwood, 1989; Benzing, 1990; Densmore & Zasada, 1983] Also, how did he distribute them all over the world?
How did all the fish survive? Some require cool clear water, some need brackish water, some need ocean water, some need water even saltier. A flood would have destroyed at least some of these habitats.
How did sensitive marine life such as coral survive? Since most coral are found in shallow water, the turbidity created by the runoff from the land would effectively cut them off from the sun. The silt covering the reef after the rains were over would kill all the coral. By the way, the rates at which coral deposits calcium are well known, and some highly mature reefs (such a the great barrier) have been around for millions of years to be deposited to their observed thickness.
How did diseases survive? Many diseases can't survive in hosts other than humans. Many others can only survive in humans and in short-lived arthropod vectors. The list includes typhus, measles, smallpox, polio, gonorrhea, syphilis. For these diseases to have survived the Flood, they must all have infected one or more of the eight people aboard the Ark.
Other animals aboard the ark must have suffered from multiple diseases, too, since there are other diseases specific to other animals, and the nonspecific diseases must have been somewhere.
Host-specific diseases which don't kill their host generally can't survive long, since the host's immune system eliminates them. (This doesn't apply to diseases such as HIV and malaria which can hide from the immune system.) For example, measles can't last for more than a few weeks in a community of less than 250,000 [
Keeling & Grenfell, 1997] because it needs nonresistant hosts to infect. Since the human population aboard the ark was somewhat less than 250,000, measles and many other infectious diseases would have gone extinct during the Flood.
Some diseases that can affect a wide range of species would have found conditions on the Ark ideal for a plague. Avian viruses, for example, would have spread through the many birds on the ark. Other plagues would have affected the mammals and reptiles. Even these plague pathogens, though, would have died out after all their prospective hosts were either dead or resistant.
How did short-lived species survive? Adult mayflies on the ark would have died in a few days, and the larvae of many mayflies require shallow fresh running water. Many other insects would face similar problems.
How could more than a handful of species survive in a devastated habitat? The Flood would have destroyed the food and shelter which most species need to survive.
How did predators survive? How could more than a handful of the predator species on the ark have survived, with only two individuals of their prey to eat? All of the predators at the top of the food pyramid require larger numbers of food animals beneath them on the pyramid, which in turn require large numbers of the animals they prey on, and so on, down to the primary producers (plants etc.) at the bottom. And if the predators survived, how did the other animals survive being preyed on?
How could more than a handful of species survive random influences that affect populations? Isolated populations with fewer than 20 members are usually doomed even when extraordinary measures are taken to protect them. [
