Math and fossils resolve a debate on dinosaur metabolism
Of the many mysteries surrounding the life history of dinosaurs, one of the more enduring is how such gigantic organisms—some reaching 42 feet tall and weighing 90 tons—regulated their body temperature. view more (2006-07-11)
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)
Polygamy, paternal care in birds linked to dinosaur ancestors
Sure, they're polygamous, but male emus and several other ground-dwelling birds also are devoted dads, serving as the sole incubators and caregivers to oversized broods from multiple mothers. view more (2008-12-19)
Why an Allosaurus's butt is worse than its bite
At up to 12 metres long and weighing as much as two tonnes, the Allosaurus is recognised as having been one of the fiercest dinosaurs of the late Jurassic age. But its slender teeth and sometimes narrow jaw bone have left scientists puzzled as to how the Allosaurus managed to hunt prey successfully. Emily Rayfield, of the University of Cambridge's... view more... (2001-02-19)
Mysterious mountain dino may be a new species
A partial dinosaur skeleton unearthed in 1971 from a remote British Columbia site is the first ever found in Canadian mountains and may represent a new species, according to a recent examination by a University of Alberta researcher. view more (2008-06-13)
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)
Paleontologists establish first age distribution of non-avian dinosaur population
For the first time, scientists have established the age structure of a non-avian dinosaur population. Using this information, they inferred which factors led to survival or death of group members. view more (2006-07-17)
Discovery raises new doubts about dinosaur-bird links
Researchers at Oregon State University have made a fundamental new discovery about how birds breathe and have a lung capacity that allows for flight - and the finding means it's unlikely that birds descended from any known theropod dinosaurs. view more (2009-06-09)
T. rex quicker than Becks, say scientists
T. rex may have struggled to chase down speeding vehicles as the movie Jurassic Park would have us believe but the world's most fearsome carnivore was certainly no slouch, research out today suggests. view more (2007-08-22)
Next good dinosaur news likely to come from small packages
Dinosaurs seem bigger than life - big bones, big mysteries. So it's a delicious irony that the next big answers about dinosaurs may come from small - very small - remains. view more (2006-02-17)
Velociraptor had feathers
A new look at some old bones have shown that velociraptor, the dinosaur made famous in the movie Jurassic Park, had feathers. A paper describing the discovery, made by paleontologists at the American Museum of Natural History and the Field Museum of Natural History, appears in the Sept. 21 issue of the journal Science. view more (2007-09-21)
Crushed bones reveal literal dino stomping ground
Imagine the gruesome sound of bones snapping as a thirsty, 30-ton dinosaur tramples a heap of fresh carcasses on his way to a rapidly shrinking lake. view more (2009-10-14)
Steep oxygen decline halted first land colonization by Earth's sea creatures
Vertebrate creatures first began moving from the world's oceans to land about 415 million years ago, then all but disappeared by 360 million years ago. view more (2006-10-24)
Latest study: scientists say no evidence exists that therapod dinosaurs evolved into birds
No good evidence exists that fossilized structures found in China and which some paleontologists claim are the earliest known rudimentary feathers were really feathers at all, a renowned ornithologist says. view more (2005-10-10)
Giant frog jumps continents
A giant frog fossil from Madagascar dubbed Beelzebufo or 'the frog from Hell' has been identified by scientists from UCL (University College London) and Stony Brook University, New York. view more (2008-02-19)
Trotting with emus to walk with dinosaurs
One way to make sense of 165-million-year-old dino tracks may be to hang out with emus, say paleontologists studying thousands of dinosaur footprints at the Red Gulch Dinosaur Tracksite in northern Wyoming. view more (2006-10-25)
Large dinosaurs were extremely hot in their day, UF study finds
If you think dinosaurs are hot today, just think back to about 110 million years ago when they really ran hot and heavy. view more (2006-07-12)
Iridescence found in 40-million-year-old fossil bird feather
Known for their wide variety of vibrant plumage, birds have evolved various chemical and physical mechanisms to produce these beautiful colors over millions of years. view more (2009-08-27)
Beaked, bird-like dinosaur tells story of finger evolution
Scientists have discovered a unique beaked, plant-eating dinosaur in China. The finding, they say, demonstrates that theropod, or bird-footed, dinosaurs were more ecologically diverse in the Jurassic period than previously thought, and offers important evidence about how the three-fingered hand of birds evolved from the hand of dinosaurs. view more (2009-06-18)
