These Jurassic predators resorted to cannibalism when hit with hard times, according to a deliciously rare discovery.
- Rare fossil evidence of dinosaur cannibalism among the Allosaurus has been discovered.
- Scientists analyzed dinosaur bones found in the Mygatt-Moore Quarry in western Colorado, paying special attention to bite marks that were present on 2,368 of the bones.
- It's likely that the predatory carnivore only ate their already-dead peers during times when resources were scarce.
You think you've had a day where everything that went wrong could? T-Rex has you beat.
- A new study suggests that the object that brought about the end of the dinosaurs crashed into the Earth at a 60-degree angle.
- This is about the worst possible angle for such an impact.
- The findings also help explain the nature of the impact crater in Yucatan.
Researchers think they know how a group of ancient sloths, who died thousands of years ago in Ecuador, met their untimely end.
- Evidence collected from an ancient boneyard in Ecuador suggests that a group of 22 ancient giant sloths died in a wallow of their own feces.
- Other mammals, such as a deer, a horse, an elephant-like creature called a gomphothere, and another species of ground sloth were identified at the site.
- The fate of the sloths parallels that of modern hippos who can become lethally poisoned in times of drought when the feces to water ratio shifts in their watering holes.
Why did the dinosaurs go extinct? Because they didn't have a space program.
- Space exploration is more than just the ultimate adventure, our study and investigation of space yields great scientific rewards, says astronaut Garrett Reisman.
- Earth is wonderful, but it won't last forever, so it's important that we maintain a big picture view to ensure the survival of the human species.
- Exploring space is our ticket to "the ultimate plan B," according to Reisman. If there were to occur a mass extinction event on Earth, the humans that inhabit another planet in our solar system will be the only hope of human survival.
Non-avian dinosaurs were thought terrestrially bound, but newly unearthed fossils suggest they conquered prehistoric waters, too.
