Chicken-hearted tyrants
Two titans fighting a bloody battle - that often turns fatal for both of them. This is how big predatory dinosaurs like Tyrannosaurus are often depicted while hunting down their supposed prey: even larger herbivorous dinosaurs. view more (2009-08-07)
Dinsaurrific!
The most comprehensive picture yet of how dinosaurs evolved has been produced by a team at Bristol University. More than 1,000 species of dinosaurs have been named since the first skeletons were dug up in the 19th century, and unravelling their patterns of evolution has been a major area of research. Since 1980, over 150 evolutionary trees of... view more... (2002-04-26)
Largest carnivorous dinosaur tooth in Spain described
Researchers from the Teruel-Dinópolis Joint Palaeontology Foundation have compared an Allosauroidea tooth found in deposits in Riodeva, Teruel, with other similar samples. view more (2009-06-22)
New Research Shows Dinosaurs May Have Been Smaller Than We Thought
For millions of years, dinosaurs have been considered the largest creatures ever to walk on land. While they still maintain this status, a new study suggests that some dinosaurs may actually have weighed as little as half as much as previously thought. view more (2009-06-26)
Fattysaurus or thinnysaurus? How dinosaurs measure up with laser imaging
Karl Bates and his colleagues in the palaeontology and biomechanics research group have reconstructed the bodies of five dinosaurs, two T. rex (Stan at the Manchester Museum and the Museum of the Rockies cast MOR555), an Acrocanthosaurus atokensis, a Strutiomimum sedens and an Edmontosaurus annectens. view more (2009-02-23)
Dinosaur extinction didn't cause the rise of present-day mammals, claim researchers
A new, complete 'tree of life' tracing the history of all 4,500 mammals on Earth shows that they did not diversify as a result of the death of the dinosaurs, says new research published in Nature today. view more (2007-03-29)
Study of polar dinosaur migration questions whether dinosaurs were truly the first great migrators
Contrary to popular belief, polar dinosaurs may not have traveled nearly as far as originally thought when making their bi-annual migration. view more (2008-10-22)
Why dinosaurs had fowl breath
Scientists have discovered how dinosaurs used to breathe in what provides clues to how they evolved and how they might have lived. view more (2007-11-07)
Luck gave dinosaurs their edge
T. rex and Triceratops: In the popular imagination, dinosaurs are extraordinary reptiles that ruled the world for over 160 million years. But Steve Brusatte, a doctoral student at Columbia University who is an affiliate of the American Museum of Natural History, and colleagues are challenging this idea with new fossil data and math. view more (2008-09-12)
Duck-billed dinosaur crests not linked to sense of smell
After decades of debate, a U of T researcher has finally determined that duck-billed dinosaurs' massive but hollow crests had nothing to do with what many scientists suspected - the sense of smell. view more (2006-01-25)
New dinosaur species possible in Northwestern Alberta
The discovery of a gruesome feeding frenzy that played out 73 million years ago in northwestern Alberta may also lead to the discovery of new dinosaur species in northwestern Alberta. view more (2009-05-13)
Dinosaurs Did Not Hatch Their Eggs
Dinosaurs laid eggs, but as dinosaurs were much heavier than birds, dinosaurs were unable to hatch the eggs. They would have simply broken them. The eggs at that time were alive, fragile, not fossilized and could not stand heavy pressure. Anyway, dinosaurs were reptiles and the reptiles do not sit on the nests. But did they take care of the... view more... (2001-12-25)
Emory paleontologist reports discovery of carnivorous dinosaur tracks in Australia
The first fossil tracks belonging to large, carnivorous dinosaurs have been discovered in Victoria, Australia, by paleontologists from Emory University, Monash University and the Museum of Victoria (both in Melbourne). view more (2007-10-22)
Was male domination deadly for dinosaurs?
Dinosaurs suddenly died out because they gave birth to too many males as a result of climate change. This is the theory put forward by David Miller of medicine and Jonathen Summers of mechanical engineering at the University of Leeds. They believe that dinosaur populations died out because the sex of their offspring was determined by temperature.... view more... (2004-05-10)
Evidence of the 'Lost World' -- did dinosaurs survive the end Cretaceous extinctions?
The Lost World, Sir Arthur Conan Doyle's account of an isolated community of dinosaurs that survived the catastrophic extinction event 65 million years ago, has no less appeal now than it did when it was written a century ago. view more (2009-04-28)
Height or flight?
Paleontologists have long theorized that miniaturization was one of the last stages in the long series of changes required in order for dinosaurs to make the evolutionary "leap" to take flight and so become what we call birds. view more (2007-09-07)
Diminishing dinosaur steps saved by laser and laptop
The Fumanya site, in the Bergueda region of central Catalonia, is so delicate that experts cannot get physically close enough to the tracks to examine them. view more (2007-05-10)
Possible dinosaur burrows clues to survival strategies
Internationally renowned palaeontologist and Monash University Honorary Research Associate, Dr Anthony Martin has found evidence of a dinosaur burrow along the coast of Victoria, which helps to explain how dinosaurs protected themselves from climate extremes during the Cretaceous period - the final era for dinosaurs before their extinction. view more (2009-07-16)
U of A researcher has rare evidence of dinosaur cannibalism
University of Alberta researcher Phil Bell has found 70 million year old evidence of dinosaur cannibalism. view more (2009-10-07)
Unexpected finding: Some dinosaurs grew slower in hard times
Palaeontologists from the University of Bonn report on an intriguing diagnosis in the 16 December issue of the journal Science. A dinosaur which they have examined was apparently able to vary the speed of its growth according the conditions obtaining in its environment. view more (2005-12-16)
