This means trilobites, dinosaurs, and mammals all dwelled on the planet simultaneously, and they perished together in this world-destroying cataclysm.
Although creationists have long pointed out the rock formations themselves testify unmistakably to water catastrophism on a global scale, evolutionists generally have ignored this testimony.
With the discovery of radioactivity about a hundred years ago, evolutionists deeply committed to the uniformitarian outlook believed they finally had proof of the immense antiquity of the earth.
In particular, they discovered the very slow nuclear decay rates of elements like Uranium while observing considerable amounts of the daughter products from such decay.
This is partly due to the legacy of the doctrine of uniformitarianism passed down from one generation of geologists to the next since the time of Charles Lyell in the early nineteenth century.
Even if they cannot provide a naturalistic mechanism, they appeal to the "fact of evolution," by which they mean an interpretation of earth history with a succession of different types of plants and animals in a drama spanning hundreds of millions of years.They interpreted these discoveries as vindicating both uniformitarianism and evolution, which led to the domination of these beliefs in academic circles around the world throughout the twentieth century.However, modern technology has produced a major fly in that uniformitarian ointment.A key technical advance, which occurred about 25 years ago, involved the ability to measure the ratio of C ratio from approximately 1% of the modern value to about 0.001%, extending the theoretical range of sensitivity from about 40,000 years to about 90,000 years.
The only consistent way to interpret the geological record in light of this event is to understand that fossil-bearing rocks are the result of a massive global Flood that occurred only a few thousand years ago and lasted but a year.
This Biblical interpretation of the rock record implies that the animals and plants preserved as fossils were all contemporaries.
