Prehistoric sea reptile gave birth, didn't lay eggs

Ancient reptile a bit like a whale

The remains of a giant sea creature are providing the first proof that the prehistoric reptiles gave birth to their young rather than lay eggs. Plesiosaurs, which lived at the time of dinosaurs, were large carnivorous sea animals with broad bodies and two pairs of flippers. Researchers have long questioned whether they could have crawled onto land and laid eggs like other reptiles or given birth in the water like whales. The newly unveiled fossil was originally discovered in 1987 in Logan County in Kansas. Encased in rock, it was stored in the basement of the Natural History Museum of Los Angeles County until resources were available to separate the bones for display at the museum.

Glider launches, but contact lost

An unmanned hypersonic glider developed for U.S. defense research into super-fast global strike capability was launched atop a rocket early Thursday, but contact was lost after the experimental craft began flying on its own, the Defense Advanced Research Projects Agency said. There was no immediate information on how much of the mission's goals were achieved. The launch from Vandenberg Air Force Base, 130 miles northwest of Los Angeles, was the second of two planned flights of a Falcon Hypersonic Technology Vehicle-2. Contact was also lost during the first mission. The HTV-2 is designed to be launched to the edge of space, separate from its booster and maneuver through the atmosphere at 13,000 mph before intentionally crashing into the ocean.
