97K Scientists use a combination of relative and numerical dating to establish the age of rocks and fossils. Explore these two methods and learn how each one works. Related to this QuestionWhat are some examples of relative dating? What is the definition of relative dating? What are the law...
Darwin's discovery of giant fossils during the voyage helped to establish his reputation as a geologist, and his theorizing about the causes of their extinction led to his theory of evolution by natural selection, published in On the Origin of Species in 1859. During the 19th century, the gov...
What were the major geologic events of the Silurian period? What are some examples of index fossils? What is geological heritage? What are the major processes of the rock cycle? What were the major geologic events of the Quaternary period?
National Gallery– This art museum was founded in 1824 and houses a collection of over 2,300 paintings dating from the mid-13th century to around 1900. There are works by Johannes Vermeer, Sandro Botticelli, Rembrandt, and Michelangelo, among many more! It’s a really extensive and wonderful...
Archaeans are an ancient form of life, possibly the most ancient. Putative fossils of archaean cells in stromatolites have been dated to almost 3.5 billion years ago, and the remains of lipids that may be either archaean or eukaryotic have been detected in shales dating from 2.7 billion year...
rocks are found in the northwestern Pacific Ocean and the eastern Mediterranean Sea. Fragments of continental crust are much older, with large chunks at least 3.8 billion years old found in Greenland and smaller sections of continental crust dating to around4.4 billion years ago found in Australia...

It’s not a field that’s well-suited for those fearful of being wrong. I’ll never think these outputs are perfect; that is a crazy notion; but today I feel pretty good. This was a long time coming for me, and it is satisfying to get to this stage where we can push forwards ...
While paleontologists have studied fossils for centuries, the science of mass extinction is relatively new. Radiometric dating, based on the natural radioactive decay of certain elements, like carbon, and other techniques revolutionized the ability to precisely determine the age of ancient rocks in the...
“I think of them as like really beefy wolverines or basically like pitbulls. They have really big heads that were just covered in muscle,” said Dr. Matthew Borths, curator of fossils at the Duke Lemur Center Museum of Natural History at Duke University in Durham, North Carolina. The ra...
