The oldest fossils ever discovered are more than 3.5 billion years old.National Geographic reports that scientist Dallas Abbott from Columbia University has been gathering data and announcing for the past ten years that a giant tsunami deposited ocean floor sediment on Madigascar.The sediments cover an area 2 times the size of Manhattan and are over 600 feet tall.The nodosaur remains were actually discovered back in 2011 by a miner and only revealed to the world on May 12, 2017, reports National Geographic.This fossil specimen was so well-preserved that patches of its skin, armor and even what archeologists speculate to be its last meal remained, after being entombed in the earth for 110 million years.Some of the isotopes used for this purpose are uranium-238, uranium-235 and potassium-40, each of which has a half-life of more than a million years.
Unfortunately, these elements don't exist in dinosaur fossils themselves.
Fossils are the remains of animals or plants that lived a long time ago.
When we think of fossils, the first things that come to mind are the bones of dinosaurs; but a fossil can be anything.
