Tyronnosaurus rexes weren’t alive at the same time; therefore, their stratum didn’t get laid down at the same time.
Benjamin Franklin saw that there were fossilized sea shells on top of the mountains of Appalachia, some of them imprinted into solid rock, and concluded, “Tis certainly the Wreck of a World we live on!
By comparing the ratio of uranium-238 to lead-206, we can estimate how old the rock is.
The same thing can be done with Samarium-neodymium, Potassium-argon, Rubidium-strontium, and Uranium-thorium transitions. There is a semi-constant ratio of carbon-14 in the air and ocean as it is constantly being created by cosmic rays.
Plants take in carbon from the atmosphere and ocean and fix it into themselves.
You will never find a Neanderthal bone in the same stratum as a Tyrannosaurus rex bone.
” The shells were deposited in layers on the Ocean floor over millions of years, layers that would be violently broken up and rippled into a mountain range 480,000,000 years ago by a catastrophic earthquake.
South America fits into Africa, rocks get younger the closer you get to where the crust is spreading under the ocean, and satellites have observed the drift.
By measuring the ratio of carbon-14 in a younger fossil, scientists can estimate its age.
These fossilized bacterial colonies date back 2.7 billion years and may extend 3.4 billion years.
All life on Earth uses a three-letter code to produce 20 standard amino acids.
