Why would plants and animals normally not be found together in the fossil strata?
The reason is simple enough. They were all washed into place by the worldwide Flood. The water tended to sort them out, resulting in rafts of vegetation being floated into place, which became our present coal beds, while other pockets in the strata became filled with “fossil graveyards” as animals were washed into other locations. IN WHAT FORM ARE THE FOSSILS?—There are millions upon millions of fossils. You may wonder what those fossils are like. Here are the seven primary types of fossils: (1) Hard parts (the bones and shells) of some plants and animals were preserved. (2) Carbon alone was preserved. This is where our coal beds came from. (3) The original form is preserved only in casts and molds. The original material dissolved away and a cast of its shape was preserved. This would also require sudden burial. (4) Sometimes petrification of wood occurred. An excellent example of this would be the Petrified Forest in Arizona, where we find entire tree trunks that have turned to stone.
