Rapid growth, early maturity meant teen pregnancy for dinosaurs

01-14-2008 · EurekAlert!

Now that scientists have identified the fossil bones of three female dinosaurs, each a different species, it has become clear that dinosaurs exhibited rapid growth and early maturity, probably because they had a high early mortality rate. UC-Berkeley and Ohio University paleontologists report details of two of the three and argue that dinosaurs reached sexual maturity in their teens, more akin to mammals than to their reptile ancestors or their descendents, the birds.

T. rex had teen pregnancies
01-14-2008 · EurekAlert!
Dinosaurs had pregnancies as early as age 8, far before they reached their maximum adult size, a new study finds. Researchers at Ohio University and University of California at Berkeley have found medullary bone -- the same tissue that allows birds to develop eggshells -- in two new dinosaur specimens: the meat-eater Allosaurus and the plant-eater Tenontosaurus. It's also been found in Tyrannosaurus rex.

Rise of dinosaurs in Late Triassic more gradual than once thought
07-19-2007 · EurekAlert!
The ancestors of dinosaurs seemed to disappear before the dinosaurs took over the Earth 200 million years ago, suggesting to many that dinosaurs were so successful that they rapidly out-competed their ancestors and drove them extinct. New fossil finds in New Mexico, however, show that this was not true -- dinosaurs and their ancestors lived side by side for 15-20 million years in the Late Triassic before the dinosaur precursors vanished.

'Clumping' protein linked to return of ovarian cancer
12-15-2006 · EurekAlert!
Johns Hopkins scientists have discovered that women treated for ovarian cancer are at increased risk of a rapid and potentially fatal recurrence if their tumor cells have high levels of a binding protein that triggers abnormal growth and slows down cell death, both hallmarks of malignancy.

Height or flight?
09-06-2007 · EurekAlert!
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. New evidence from a tiny Mongolian dinosaur, however, may leave some current theories about the evolution of flight up in the air.

Seismic images show dinosaur-killing meteor made bigger splash
01-23-2008 · EurekAlert!
The most detailed 3-D seismic images yet of the Chicxulub impact crater may modify a theory explaining the "KT Extinction Event" that wiped out most life on Earth, including the dinosaurs. According to research appearing in Nature Geosciences, the asteroid landed in deeper water than previously assumed and therefore released about 6.5 times more water vapor into the atmosphere, possibly making it deadlier by altering climate and generating acid rain.

Trotting with emus to walk with dinosaurs
10-24-2006 · EurekAlert!
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. Because they are about the same size, walk on two legs and have similar feet, emus turn out to be the best modern version of the enigmatic reptiles that once trotted along a long-lost coastline in the Middle Jurassic.
