Fossils from the Jehol Biota capture evolution in action

What Happens After a Fossil Is Discovered?

The discovery of a fossil marks just the beginning of an extensive scientific journey. When paleontologists or fortunate amateurs stumble upon these ancient remnants, they initiate a meticulous process that can span months or even years before the specimen’s secrets are fully revealed. These prehistoric treasures provide crucial glimpses into Earth’s distant past, helping scientists ...

A rare gem from the past: Barb Beasley’s discovery of a Tyrannosaurus rex tooth during a 2012 Passport in Time excavation in the iconic Hell Creek Formation.

Fossil Forensics: What a Single Tooth Can Tell Us About the Past

A single ancient tooth, sometimes no larger than a thumbnail, can unlock extraordinary secrets about life on Earth millions of years ago. In the skilled hands of paleontologists and researchers, these seemingly modest remains transform into powerful storytelling devices that illuminate extinct species, ancient ecosystems, and even evolutionary turning points. Fossil teeth serve as time ...

Fossil-Hunting for Profit: Science Killer or Necessary Evil?

In the rugged badlands of Montana, a Tyrannosaurus rex skeleton emerges from ancient sediment, painstakingly excavated not by university paleontologists but by commercial fossil hunters. The specimen, later named “Sue,” would eventually sell for $8.3 million at auction, triggering both celebration and alarm throughout the scientific community. This scenario encapsulates one of paleontology’s most contentious ...

How Do Paleontologists Study Dinosaur Behavior from Fossils?

Unlocking the secrets of dinosaur behavior is like assembling a complex puzzle with many missing pieces. Paleontologists face the remarkable challenge of understanding how creatures behaved millions of years ago, with only their fossilized remains as evidence. Despite these limitations, scientific ingenuity and advancing technology have enabled researchers to develop sophisticated techniques for interpreting dinosaur ...

Microraptor's aerodynamic feathers hint at gliding or even early flight, soaring through prehistoric skies.

Are We Over-Interpreting Fossils with Modern Bias?

The study of ancient life through paleontology has revolutionized our understanding of Earth’s biological past. By examining fossils—preserved remains or traces of organisms from previous geologic periods—scientists reconstruct extinct species and ecosystems that existed millions of years ago. However, a growing concern within the scientific community questions whether modern human biases and perspectives unconsciously influence ...

Why Fossilized Dinosaur Skin Impressions Are So Rare (and So Valuable)

When we think of dinosaur fossils, we typically envision bones and teeth preserved in rock—the hard parts that withstood the test of time. However, some of the most scientifically significant and valuable dinosaur fossils aren’t bones at all, but rather the impressions of soft tissues like skin. These remarkable fossilized skin impressions offer paleontologists unprecedented ...
