After more than a century of debate, researchers have finally cracked the puzzle of why T. rex had such comically small arms. The answer reveals a fascinating trade-off that shaped dinosaur evolution for 180 million years.
A family boat trip turned into a paleontology breakthrough when restless kids discovered the bones of a massive ancient sea predator on a Texas lakeshore. Forty-five years later, scientists officially named it Tylosaurus rex.
Scientists finally know why T. rex had such famously small arms. New research shows the fearsome predator evolved massive jaws and a powerful skull instead, making arms unnecessary for hunting.
A lab has grown experimental leather using AI, chicken proteins, and contested T. rex fossil data, creating a handbag that's sparking curiosity about biotechnology. While it's 90% chicken, the project is getting people excited about science.
Scientists in Japan discovered extinct octopuses that grew up to 60 feet long and hunted massive marine reptiles millions of years ago. New technology is finally revealing these soft-bodied predators that dominated ancient oceans alongside T. rex on land.
New research reveals how birds outlived T. rex and other mighty dinosaurs 66 million years ago. A few key traits helped our feathered friends survive Earth's worst extinction event.

A single fossil bed in Montana has unlocked nearly everything we know about T. rex and the final moments before dinosaurs vanished forever. Scientists are still finding treasures that show how life bounced back after Earth's most famous catastrophe.
The James Webb Space Telescope photographed a stunning spiral galaxy 65 million light-years away, meaning the light left that galaxy when T. rex walked Earth. Two powerful instruments combined to reveal intricate details scientists are using to understand how stars form and die.
The James Webb Space Telescope just revealed a spiral galaxy whose light began its journey to Earth right after dinosaurs went extinct. Scientists are using this remarkably clear view to unlock secrets about how galaxies evolve across billions of years.
A massive leg bone discovered in New Mexico belongs to a tyrannosaur that lived 74 million years ago and might be a direct ancestor of the famous T. rex. At nearly 5 tons, this ancient predator was bigger than any other tyrannosaur of its era.
New research reveals the mighty Tyrannosaurus rex took twice as long as scientists thought to reach full size, growing slowly over four decades instead of just 25 years. This discovery could explain how T. rex dominated as the apex predator for millions of years.
Scientists discovered that Tyrannosaurus rex didn't reach full size until around age 40, much later than previously thought. The findings reveal these prehistoric giants spent most of their lives as smaller, less fearsome versions of themselves.
Scientists discovered that Tyrannosaurus rex took about 40 years to reach its massive eight-ton size, a full decade longer than previously believed. The finding reveals these mighty dinosaurs had surprisingly flexible growth patterns that helped them survive and dominate.
