Coastal Redwood trees stand at Muir Woods National Monument on August 20, 2013, in Mill Valley, California. A recent study found that redwoods have two distinct types of leaves — one for absorbing water and one for photosynthesis. The placement of the leaf types changes across their range depending on how wet or dry their conditions are. (Justin Sullivan/Getty Images)

Researcher Ashley Poust holds the fossilized lower jaw of Diegoaelurus, a bobcat-sized carnivore that lived 42 million years ago. Diegoaelurus was much smaller than the commonly known Smilodon, or saber-tooth cat, seen in the background. Smilodon evolved roughly 40 million years after Diegoaelurus went extinct, but both animals were saber-toothed, hyper-carnivorous predators, meaning their diets consisted almost entirely of meat.
