During the Triassic period nearly 250 million years ago, a small reptile scurried after insects in the canopy of a lush ...

The painted desert of Arizona’s Petrified Forest National Park is a fossil wonderland. Scattered through the sunbeaten rock are rainbow-colored trunks of prehistoric conifers, the crumbling bones of ...

The start of the Triassic period (and the Mesozoic era) was a desolate time in Earth's history. Something—a bout of violent volcanic eruptions, climate change, or perhaps a fatal run-in with a ...

The Triassic period stands out in Earth’s history as the time when dinosaurs first evolved. It was followed by the Jurassic and Cretaceous periods – at the end of the latter, the dinosaurs ...

The Triassic is one of the most important periods in the evolution of life on Earth. After one of the greatest mass extinctions 252 million years ago, not only the dinosaurs but also many other ...

The genomes of conifers — pine, ... The extra DNA may have helped conifers survive the Permian-Triassic extinction about 252 million years ago, the researchers speculate.

Combining the evidence of the conifer forests' retreat, the rapid growth of ferns, and the chemical signature of volcanism, the authors conclude that the surface mass extinction in northwestern ...

The sweltering deserts of present day Nevada were once covered with water and home to an extinct crocodile relative. A team of scientists found this newly discovered species in the Triassic Era ...

The end-Triassic extinction, which happened 201 million years ago, was Earth’s third most severe extinction event since the dawn of animal life. Like today, CO 2 rise and global warming were ...

Dinocephalosaurus orientalis's snake-like body was 16 feet long and lived in Triassic China. The newly revealed specimen allows scientists to depict the creature in full for the first time.
