In a spellbinding talk, paleontologist Jack Horner tells the story of how iconoclastic thinking revealed a shocking secret about some of our most beloved dinosaurs.

Paleopathology, the study of ancient disease, is a vital way by which we understand the evolution of pathogens, immune systems, healing physiology, and ultimately the environment. Cancer research has focused on its prevalence in various organisms and has found that although some animals have a high propensity for cancer,1 others seem to be resistant.2 The prevalence of cancer in the tree of life is certainly interesting, but its antiquity should be regarded with equal interest considering the increase in human cancer, which has been related to environmental and genetic changes, and the extreme rarity of cancer in the fossil record.

People have always known of dinosaurs, though they have called them by many names. Old legends that place Western dragons in caves…

The earth was a much hotter place in prehistoric times, so it follows that large heavily-armored dinosaurs likely retained a lot of heat in their bodies. A new study suggests that their brains were protected from overheating, however, thanks to a heat exchanging system in their noses.

This meat-eating dinosaur was the first of its kind to be huge.

It led to an explosion of interest in dinosaurs, and by extension, people interested in researching them

Gerta keller was waiting for me at the Mumbai airport so we could catch a flight to Hyderabad and go hunt rocks. “You won’t die,” she told me cheerfully as soon as I’d said hello. “I’ll bring you back.” Death was not something I’d considered as a possible consequence of traveling with Keller, a 73-year-old paleontology and geology professor at Princeton University. She looked harmless enough: thin, with a blunt bob, wearing gray nylon pants and hiking boots, and carrying an insulated ShopRite supermarket bag by way of a purse.

Announcing the completion of time-consuming “cleaning” work, a research team in Hokkaido has unveiled what it claims is the largest dinosaur skeleton ever found in Japan. Through the work to remove rocks and sediments in which the fossils were embedded, a total of 157 pieces were identified as bones of a large herbivorous dinosaur from the Hadrosaurid family, according to the team comprising curators of the Hobetsu Museum in Mukawa, Hokkaido, and Yoshitsugu Kobayashi, an associate professor at the Hokkaido University Museum.

The ancestors of today’s squamates were lost in time. Now paleontologists have identified the earliest known example: Meet Megachirella.

In the oxygen-poor air of the Mesozoic era, nothing should have been able to move very fast. But Velociraptors could run 64 kilometers per hour. Their secret weapon: superefficient, birdlike lungs, which would have pumped in a constant supply of oxygen, according to a new study. This unique adaptation may have given all dinos a leg up on their competition.

Known as the ‘Icon of Evolution’ and ‘the missing link’ between dinosaurs and birds, Archaeopteryx has become one of the most famous fossil discoveries in Palaeontology. Now, as part of an international team of scientists, researchers at The University of Manchester have identified a new species of Archaeopteryx that is closer to modern birds...

A new study found that birds' dinosaur relatives had eggs with traces of two pigments—a red-brown one and a blue-green one. In today's birds that might produce a color such as robin's egg blue.

Tracks made by dinosaurs the size of sparrows have been discovered in South Korea by an international team of palaeontologists. University of Queensland researcher Dr Anthony Romilio was part of the team which described the tracks, which were originally found by Professor Kyung Soo Kim from Chinju National University of Education, South Korea.

Feathers found in Burmese amber dating back 100 million years are so exquisitely preserved that palaeontologists have been able to make a detailed study of their structure - and they're like nothing seen in living birds today.

Saltriovenator is the first Italian dinosaur of the Jurassic age and the only dinosaur found in the Lombardy region. Wednesday Italian paleontologists presented evidence that the world’s oldest large-predator dinosaur inhabited the European country some 200 million years ago. "Saltriovenator predates the massive meat-eating dinosaurs by over 25 million years and sheds light on the evolution of the three-fingered hand of birds," Dal Sasso of Milan's Natural History Museum said in a statement.

Scary yes or no

Feathered dinosaurs look freaky!

Feather used for sex for dinosaurs??

The real-life fossils belong to a new species of phorusrhacid, giant predators also known as terror birds that once dominated South America.

This is an amazing post-apocalyptic New Zealand dinosaur illustration by Weta concept artist and Dr. Grordbort's creator Greg Broadmore.

An eccentric Australian mining magnate who is building a replica of the ill-fated Titanic has unveiled his latest scheme -- a park of giant robotic dinosaurs. The world's biggest dinosaur exhibit will have 165 life-size animatronic dinosaurs.

Once considered beyond the reach of science, insights into the love lives of these extinct giants are emerging

The studio rolls out the 3D version of Steven Spielberg's 1993 sci-fi adventure on Friday.

Australian mining mogul Clive Palmer wants to establish an island filled with giant, robotic dinosaurs — and that’s not an April Fools’ joke, the AFP reports. Luckily, though, Palmer appears to have moved on from his original dream of cloning a dinosaur and instead has decided to fill his island with giant robotic ones. Perhaps someone finally showed the billionaire Jurassic Park.

No bones about it - students at a Bondi school were thrilled to have a prehistoric visitor.

On June 11, 1993, Steven Spielberg's Jurassic Park hit theaters, wowing audiences with its incredibly lifelike depictions of dinosaurs. It grossed $900 million worldwide. Today, the film is being rereleased in 3D, so we're celebrating its 20th anniversary a little early. Here are 20 things you might not have known about Jurassic Park.

Just how quick was the great tyrant lizard, exactly? Experts in biomechanics think she was pretty damn quick – but still probably not as fast as you think.

Reconstructing dinosaur behaviour – such as the hunting strategy of raptors – is fraught with difficulty.

This specimen is from the Judith River Formation along the Milk River in southern Alberta. It is Campanian (Late Cretaceous) in age, which corresponds to about 80 million years old. It is an example of ideal preservation, and shows all the microstructural features typical of most fossil vertebrate bone. Little or no alteration of the hydroxyapatite appears to have occurred, and a significant amount of the pore space is not infilled with minerals and retains its "spongey" texture.

A new species of dinosaur found in NE China has added further  evidence that feathers developed originally or uses other than flight.

Queensland paleontologists have discovered that the world's only recorded dinosaur stampede is largely made up of the tracks of swimming rather than running animals.

Australia's links to South America have just gotten a bit closer, but not due to economic forces, rather fossil forces. University of Queensland palaeontologist Dr Steve Salisbury was part of an international team of palaeontologists from the US, Argentina and Australia that identified a fossil that had previously only been found in South America.

University of Alberta researcher’s examination of fossilized dinosaur tail bones has led to a breakthrough finding: some feathered dinosaurs used tail plumage to attract mates, much like modern-day peacocks and turkeys.
