Fossil forensics reveals how wasps populated rotting dinosaur eggs

1000pa (July 16, 2011) — Exceptionally preserved fossils of insect cocoons have allowed researchers in Argentina to describe how wasps played an important role in food webs devoted to consuming rotting dinosaur eggs. The research is published in the scientific journal Palaeontology.

The approximately 70 million year old eggs, from gigantic titanosaur sauropod dinosaurs were discovered in 1989 in the Patagonia region of Argentina, well known...

Domed dinosaur was king of the head butt

1000pa (June 29, 2011) — Llamas can't really manage it. Giraffes aren't very good at it and while big horn sheep and muskox excel at it, it turns out a small plant eating dinosaur -- the pachycephalosaur Stegoceras validum -- was probably even better at it: head butting.

Researchers surveyed the heads of a large number of modern animals as well as one of the world's best dinosaur fossils, the Stegoceras specimen from the University of...

Body temperature of dinosaurs measured for the first time

1000pa (June 28, 2011) — Were dinosaurs slow and lumbering, or quick and agile? It depends largely on whether they were cold- or warm-blooded.

When dinosaurs were first discovered in the mid-19th century, paleontologists thought they were plodding beasts that relied on their environment to keep warm, like modern-day reptiles.

But research during the last few decades suggests that they were faster creatures, nimble like the velociraptors or T....

Body temperatures of dinosaurs measured for first time: Some dinosaurs were as warm as most modern mammals

1000pa (June 23, 2011) — Were dinosaurs slow and lumbering, or quick and agile? It depends largely on whether they were cold or warm blooded.

Immature skull led young tyrannosaurs to rely on speed, agility to catch prey

1000pa (May 10, 2011) — While adult tyrannosaurs wielded power and size to kill large prey, youngsters used agility to hunt smaller game.

"It's one of the secrets of success for tyrannosaurs -- the different age groups weren't competing with each other for food because their diets shifted as they grew," said Ohio University paleontologist Lawrence Witmer.

Witmer is part of an international team of scientists from Japan, Mongolia and the...

Endogenous proteins found in a 70-million-year-old giant marine lizard

1000pa (May 2, 2011) — A research team in Lund, Sweden has discovered primary biological matter in a fossil of an extinct varanoid lizard (a mosasaur) that inhabited marine environments during Late Cretaceous times. Using state-of-the-art technology, the scientists have been able to link proteinaceous molecules to bone matrix fibres isolated from a 70-million-year-old fossil -- that is, they have found genuine remains of an extinct animal...

The eyes have it: Dinosaurs hunted by night

1000pa (Apr. 15, 2011) — The movie Jurassic Park got one thing right: Those velociraptors hunted by night while the big plant-eaters browsed around the clock, according to a new study of the eyes of fossil animals. The study will be published online April 14 in the journal Science.

This conclusion overturns the conventional wisdom that dinosaurs were active by day while early mammals scurried around at night, said Ryosuke Motani, professor...

Birds inherited strong sense of smell from dinosaurs

1000pa (Apr. 13, 2011) — Birds are known more for their senses of vision and hearing than smell, but new research suggests that millions of years ago, the winged critters also boasted a better sense for scents.

A study published April 12 by scientists at the University of Calgary, the Royal Tyrrell Museum and the Ohio University College of Osteopathic Medicine tested the long-standing view that during the evolution from dinosaurs to birds,...

New species of dinosaur bridges gap in dinosaur family tree

1000pa (Apr. 13, 2011) — A team of scientists led by the Smithsonian Institution has discovered a fossilized dinosaur skull and neck vertebrae that not only reveal a new species, but also an evolutionary link between two groups of dinosaurs. The new species, Daemonosaurus chauliodus, was discovered at Ghost Ranch, N.M. The team's findings are published in the Proceedings of the Royal Society B on April 13.

Did dinosaurs have lice? Researchers say it's possible

1000pa (Apr. 6, 2011) — A new study louses up a popular theory of animal evolution and opens up the possibility that dinosaurs were early -- perhaps even the first -- animal hosts of lice.

The study, in Biology Letters, uses fossils and molecular data to track the evolution of lice and their hosts. It offers strong evidence, the researchers said, that the ancestors of lice that today feed on birds and mammals began to diversify before a...

Rare 89-million-year-old flying reptile fossil from Texas may be world's oldest pteranodon

1000pa (Mar. 1, 2011) — Fossilized bones discovered in Texas from a flying reptile that died 89 million years ago may be the earliest occurrence of the prehistoric creature known as Pteranodon.

Previously, Pteranodon bones have been found in Kansas, South Dakota and Wyoming in the Niobrara and Pierre geological formations. This likely Pteranodon specimen is the first of its kind found in Texas, according to paleontologist Timothy S. Myers...

'Thunder-thighs' dinosaur discovered: Brontomerus may have used powerful thigh muscles to kick predators

1000pa (Feb. 23, 2011) — A new dinosaur named Brontomerus mcintoshi, or "thunder-thighs" after its enormously powerful thigh muscles, has been discovered in Utah, USA. The new species is described in a paper recently published in the journal Acta Palaeontologica Polonica by an international team of scientists from the UK and the US.

A member of the long-necked sauropod group of dinosaurs which includes Diplodocus and Brachiosaurus, Brontomer...

3-D digital dinosaur track download: A roadmap for saving at-risk natural history resources

1000pa (Feb. 12, 2011) — Portable laser scanning technology allows researchers to tote their latest fossil discovery from the field to the lab in the form of lightweight digital data stored on a laptop. But sharing that data as a 3D model with others requires standard formats that are currently lacking, say paleontologists at Southern Methodist University.

The SMU researchers used portable laser scanning technology to capture field data of...

Secrets of dinosaur footprints revealed, thanks to 'Goldilocks'

1000pa (Feb. 8, 2011) — Terrain thought to be ruled by only the largest dinosaurs to inhabit Earth could have in fact been home to dozens of other creatures, ground-breaking research from The University of Manchester has found.

Writing in the journal of the Royal Society Interface, Dr. Peter Falkingham has discovered that dinosaurs only created lasting footprints if the soil conditions were perfect to do so -- and entirely depending on the...

How to tell a pterodactyl's sex: Dino-era riddle solved by new fossil find

1000pa (Jan. 20, 2011) — The discovery of an ancient fossil, nicknamed 'Mrs T', has allowed scientists for the first time to sex pterodactyls -- flying reptiles that lived alongside dinosaurs between 220-65 million years ago.

Pterodactyls featured prominently in Spielberg's Jurassic Park III and are a classic feature of many dinosaur movies where they are often depicted as giant flying reptiles with a crest.

New species of ancient flying reptile identified on British Columbia coast

1000pa (Jan. 10, 2011) — Persistence paid off for a University of Alberta paleontology researcher, who after months of pondering the origins of a fossilized jaw bone, finally identified it as a new species of pterosaur, a flying reptile that lived 70 million years ago.

Victoria Arbour says she was stumped when the small piece of jaw bone was first pulled out of of a fossil storage cabinet in the U of A's paleontology department.

"It could...

Oldest dinosaur embryos give insights into infancy and growth

1000pa (Nov. 12, 2010) — After sitting in collections for nearly 30 years, some remarkably well-preserved dinosaur eggs and their contents are offering new insights into the infancy and growth of early dinosaurs. They represent the oldest embryos of any land-dwelling vertebrate ever found.

The eggs, found in 1976 in South Africa, date from the early part of the Jurassic Period, 190 million years ago. They belong to Massospondylus (măs-ō-spŏn...

Tracks of a running bipedal baby brontosaur? Baby sauropod footprints discovered in Colorado

1000pa (Nov. 1, 2010) — Staff at the Morrison Natural History Museum have again discovered infant dinosaur footprints in the foothills west of Denver, Colorado, near the town of Morrison. Dating from the Late Jurassic, some 148 million years ago, these tracks were made before the Rocky Mountains rose, when Morrison was a broad savanna full of dinosaurs.

The fossil tracks represent infant sauropods, according to discoverer Matthew...

Oldest evidence of dinosaurs in footprints: Dinosaur lineage emerged soon after massive Permian extinction

1000pa (Oct. 6, 2010) — The oldest evidence of the dinosaur lineage -- fossilized tracks -- is described in Proceedings of the Royal Society B. Just one or two million years after the massive Permian-Triassic extinction, an animal smaller than a house cat walked across fine mud in what is now Poland.

This fossilized trackway places the very closest relatives of dinosaurs on Earth about 250 million years ago -- 5 to 9 million years earlier...

New fossil suggests dinosaurs not so fierce after all

1000pa (Oct. 6, 2010) — A new species of dinosaur discovered in Arizona suggests dinosaurs did not spread throughout the world by overpowering other species, but by taking advantage of a natural catastrophe that wiped out their competitors.

Tim Rowe, professor of paleontology at The University of Texas at Austin's Jackson School of Geosciences, led the effort to describe the new dinosaur along with co-authors Hans-Dieter Sues, curator of...
