If you come across a fossil, such as a shell, trilobite, or ancient bone, the most important thing to do is to leave it alone.

The booming fossil industry on the Jurassic Coast

Ever since the Jurassic Coast was registered as a UNESCO World Heritage site in 2001, professional and amateur fossil-finders have increasingly set out for its craggly cliffs to discover ammonites, icthyosaurs, and even new discoveries. This photo essay takes a human look at the growing interest and industry in fossil discoveries along the famed 95-mile strip of England.

When is it OK to dig up the dead?

Human bones tell stories that would otherwise be lost to history. But archaeologists are increasingly confronted with demands to let past generations rest in peace, according to this article.

A timeline of human fossil discoveries

A key part of writing a coherent story about our origins is finding and identifying the remains of our ancestors and understanding their significance. Scientists will not always agree on identifications and opinions will change as new find are made and new ways of studying them are developed.

Fossils form in environments where dead organisms can be rapidly buried

Such landscapes enable corpses to be encased by terrain before significant decay occurs. They are most commonly found in river deltas and sinking coastal regions, where sediments accumulate over time until geological forces expose the areas to erosion, revealing embedded fossils.

Paleontologists apply rules about rock layering, fossilization, and radioactivity to date geological samples

Concepts such as the understanding that older rock layers will form beneath newer ones allow scientists to compare the ages of samples from various layers. Although no geological site preserves evidence across all time, samples can be combined with fossils of known age, such as those dated by analyzing the decay of their radioactive isotopes, to reconstruct Earth's timeline.

Explore these collections of early human fossils

The human fossil record is filled with massive gaps, leaving archaeologists tiny samples to try and glean the history of our species. At this site, you can browse through the human fossil collection, including 3D rotatable scans of hundreds of fossils from different species of early humans.

As of 2023, there are about 1.1 billion objects stored in 73 of the world's largest natural history museums, but only about 16% of specimens are available in digital archives.

What is Archaeology?

If you are up-to-date on your Jurassic Park lore, then you likely already know the answer to this question. But for those of us who didn't delve into the world in dinosaurs, it's easy to assume that professionals who study old stuff likely study the remains of what came before us, right? Find out in this article by the Society for American Archaeology.

Is repatriation the answer to looted museum objects?

For many, the return of stolen art and artifacts to their places of origin is a simple solution. But, as Patricia Marroquin Norby, the Met’s curator of Native American Art, writes in this article, there are sometimes other approaches and factors to consider. Speaking specifically about the collection she oversees, Norby discusses other solutions like co-stewardship, in which collaborative relationships are built with the tribes from whom the objects were taken.

Whose bodies are held inside the American Museum of Natural History?

The American Museum of Natural History holds the remains of at least 12,000 people collected via purchase, donation, or expedition. This article by a professor of art crime details their attempt to identify the individuals whose remains the museum held. Amid questioning, AMNH announced it would change its human remains policy. At the time of the article's publication in October 2023, AMNH had few human remains on public display.

Native American tribes still are waiting for museums to return the remains of their ancestors

Civilizations of the past mistook dinosaur fossils for dead mythological creatures

Without knowledge of evolution or extinction, people believed such fossils were the bones of massive animals no one had ever seen alive, including dragons and giants. It was not until the science of paleontology and studies of extinction that these ideas were overturned definitively.

When naming a newly discovered species, it is generally frowned upon for scientists to name it after themselves, their children, or other family members.

She sells seashells by the seashore or, more accurately, she sells dinosaur fossils along the Jurassic Coast

Now known as the mother of paleontology, Mary Anning was 12 years old in 1811 when her seashore scrounging uncovered an ichthyosaur fossil, the first complete one known to the London scientific community at the time. She spent the rest of her life contributing to a field that didn’t care to welcome her. This article details her life and work.

Scientists can determine the age of rocks, fossils, and other ancient samples by measuring how many radioactive atoms in the sample have decayed, a process that occurs at precise, well-known rates.

Because various climate factors can affect the abundance of isotopes preserved in materials within the geologic record, these substances can serve as proxies for ancient climate conditions.

A researcher thinks she knows why people keep touching museum exhibits

A museologist who studied unauthorized touch at the British Museum concluded that people may feel it's difficult to learn about things "unless you handle them" and that people are trying to connect with the past, viscerally. Her work has included interviewing British Museum visitors who committed unauthorized touches and spending extensive periods observing people touching prohibited items across 2004 and 2005.

Searching for the history of cancer in ancient human bones

Nestled under archaeology lies bioarchaeology, which involves the study of bones, human or animal. This subfield recently birthed another field of study: paleo-oncology. Paleo-oncology looks for cancer and related biomarkers in bioarchaeological remains. This TED article explains how this nascent multidisciplinary field challenges the idea that cancer is modern.
