The fossil of a hatchling dinosaur dubbed Baby Louie is recognised as a new species of feathered dinosaur. By Helen Briggs.

The fossil of a dinosaur that has been languishing in a museum for decades has been re-examined - and it turns out to be that of a new species. Brachiosaurus, depicted in Jurassic Park, now has an early relative, providing clues to the evolution of some of the biggest creatures on Earth. Scientists say the plant-eating dinosaur was longer than a double-decker bus and weighed 15,000kg.

A volunteer unearths Richmond's first dinosaur-bird, a species previously unseen in what was Australia's inland sea.

No feathers, but specialized scales on its snout could sense vibration, heat.

On a 25 kilometre (15.5 mile) stretch of coastline in Western Australia, there lies a prehistoric treasure trove.

New research on the creatures’ family tree could “shake dinosaur paleontology to its core.”

Ancient proteins dating back 195 million years have been found inside a dinosaur bone. The discovery pushes back the oldest evidence for preserved proteins by 100 million years. Scientists have also found traces of a mineral that probably came from the blood of the early Jurassic dinosaur. Soft tissues provide new insights into the biology of dinosaurs and how they evolved.

You live in the Jurassic and you’ve evolved giant, diamond-shaped bone plates that stick out the top of your neck, back and tail. Why, evolution, why? By Darren Naish.

A pair of researchers in the U.K. has identified fossils found in the Transylvania area in Romania as those of a pterosaur they have named Hatzegopteryx—a giant, muscle-bound flying reptile that could eat prey as large as a small horse. By Bob Yirka.

An ancient mammal the size of a badger may have used its bone-crushing canines and powerful bite to take down little dinosaurs, researchers have found. In fact, the little guy could chomp down with more force, pound for pound, than any other mammal on record. The creature (Didelphodon vorax), an early marsupial relative, lived during the last few million years of the Mesozoic, or dinosaur age, in what is now present-day Montana and North Dakota, the researchers said.

Millions of years ago, a dinosaur about the size of a sparrow had a bad day. It got stuck in resin. Paleontologists recently came across the rare amber fossil containing its tail in Myanmar.

To scientists' delight, the incredible appendage from 99 million years ago is covered in feathers.

The tail of a 99-million year old dinosaur has been found entombed in amber, an unprecedented discovery that has blown away scientists.

By studying hills that formed after an asteroid struck the Yucatán Peninsula, researchers found that materials deep in Earth’s crust were brought toward the surface. By Nicholas St. Fleur.

Giant horned dinosaurs had very special nostrils... By Darren Naish.

Chinese construction workers excavating bedrock recently made an explosive discovery when they inadvertently unearthed an unusual new species of feathered dinosaur. The animal lived about 66 to 72 million years ago, right before a giant impact wiped out large dinosaurs in a catastrophic mass extinction. (Find out what happened on the day the dinosaurs died.)

Life in the southern hemisphere appears to have recovered more quickly than expected from the asteroid strike that wiped out the dinosaurs.

An unassuming lump found on a Sussex beach in 2004 contains the first known fossilized brain tissue from a dinosaur. The 133-million-year-old fossil belongs to a relative of Iguanodon, an iconic herbivorous dinosaur that lived during the early Cretaceous. The fossil mostly consists of an endocast—a sediment cast of the skull cavity where the dinosaur’s brain resided.

A new species of long-necked dinosaur revealed today had 1.5-metre wide hips and stretched half the length of a basketball court.

New studies prove that dinosaurs may not have roared in their days on the earth. NPR's Linda Wertheimer talks to paleontologist Julia Clarke about her new discovery — the cooing sounds of dinosaurs.
