Robot designed to mimic enigmatic sea creature can help us understand how it moved.

Adorned with fins down the sides of its body, a distinct head with long antennae, massive jaw structures inside its mouth and growing to more than 30 cm in length, Timorebestia koprii was one of the largest animals in the Early Cambrian oceans.

A groundbreaking study reveals the dual-cell strategy, involving repair-specific cells, behind the rapid regeneration of jellyfish tentacles, challenging existing theories and offering evolutionary insights.

A recent study on the newly discovered Qianlong shouhu, an early Jurassic sauropodomorph, suggests that the earliest dinosaur eggs had leathery shells. This finding, derived from comprehensive analyses of dinosaur fossils, indicates significant evolutionary changes in dinosaur egg morphology. The st

Paleontologists in China have unearthed and examined three adult skeletons and five clutches of embryo-containing eggs of Qianlong shouhu, a previously unknown species of Early Jurassic sauropodomorph dinosaur.

Watch as these gruesome parasites emerge from their hosts.

The new find suggests that Liassophlebiidae -- a small extinct family of damsel-dragonflies known from the Early Mesozoic -- arose in the immediate aftermath of the Triassic-Jurassic mass extinction.

Paleontologists have identified a new species of avialan (a member of the group that contains modern birds and bird-like dinosaurs) from a fossilized partial skeleton found in China.

Understanding the ancient past is critical to responding to challenges we face in the future

Turns out it's not as easy as 0, 1, 1, 2, 3.

Did our last common ancestor swing from trees or walk on all fours in the savanna?

Scientists say they have discovered an ancient lost world of organisms that lived when simple life began to evolve on Earth.

Children feel happier – and smarter – after time spent in nature. But screen time has only increased since the pandemic. Missouri is one of the states working to get students outside.

Funcusvermis gilmorei lived in the tropical forests of what is now Arizona, the United States, during the Triassic period, approximately 220 million years ago.

Paleontologists have examined the fossilized remains of Tujiaaspis vividus, a species of galeaspid that lived 436 million years ago (Silurian period) in China.

Paleontologists have discovered a 380-million-year-old heart – the oldest ever found – alongside a separate fossilized liver, stomach, and intestine in an ancient jawed fish, shedding new light on the evolution of our own bodies. Vital new evolutionary clues are provided by the research, which fo

Scientists suggest that the current extinction crisis will cause the loss of species as well as the loss of species diversity.

"Ausichicrinites zelenskyyi" is closely related to sea stars, sea cucumbers, and sea urchins.

Vampyronassa rhodanica is an ancient species of cephalopod that lived in the Jurassic oceans some 164 million years ago.

Cycads have changed a great deal since they first appeared around 280 million years ago, and habitat loss and illegal trade are now threats
