When an organism dies, its remains are exposed to various environmental factors, such as scavengers, decomposition, and weathering. For fossilization to occur, the remains must avoid rapid decay and destruction. 2. Rapid Burial: One of the critical factors in fossil formation is rapid burial. Making the Cast Fossils. Gently place the shell in the sand pan. Use the bottom of the straw to press the shell down. Press until the ring mark on the straw is even with the surface of the sand. Carefully lift the shell with the tweezers so that the impression in the sand doesn't shift or change. Feb 24, 2015 · A trace fossil is a result of animal activity. For example, a dinosaur footprint or an arthropod burrow would be an example of a trace fossil. The holes in this petrified wood are burrows made by beetles before fossilization.

Some creationists claim scientists have found dinosaur blood—actual red blood cells—in the bone of a Tyrannosaurus rex. This, they say, is proof of a recent creation. They argue dinosaur bone should be completely fossilized if it is millions of years old, but the discovery of blood cells in “fresh” bone proves dinosaur ...Based on the embryos found with the eggs, scientists theorize that the dinosaurs that laid these eggs were most likely sauropods, four-legged dinosaurs with long necks.
