Sperm whale faces]( (Jaime Bran) If the giant, extinct shark megalodon had to pick a favorite meal, the winner would likely be sperm whales ... by a nose. In fact, sperm whale noses were popular snacks not only for megalodon but also for other ancient sharks that preyed on sperm whales, according to a new analysis of fossil whale skulls.

The new date could rewrite a few key stages in the history of human evolution. That's because the finding suggests these fossils belong to a species that may predate the iconic 3.2-million-year-old "Lucy" fossil. Lucy's species was long thought to potentially have been the prime contender for the direct ancestor of humans.

This rare occurrence has "only happened twice since 1950," Zoe Gillett, a researcher at the Australia Research Council Centre of Excellence for Climate Extremes, told Live Science. But predicting La Niña is tricky, she warned; climatologists likely won't know which way the winds will blow until September.

But like every species or ecosystem, they have a birth date. In fact, though plants first arrived on land about 470 million years ago, trees and forests didn't hit the scene until nearly 390 million years ago. During that interval, plant life slowly evolved genetic precursors needed to produce trees, which then outcompeted other plants, Chris Berry, a paleobotanist at Cardiff University in the United Kingdom, told Live Science.

Often, believers will readily dismiss any and all evidence that contradicts such claims, and suggest that witnesses or experts who dispute the ideas are simply part of the conspiracy. Why do people believe in conspiracy theories, even when there is a mountain of evidence to show that they are incorrect? Why are conspiracy theories so prevalent today — and what exactly is a conspiracy theory?

Park officials warned visitors to be respectful of the enormous beasts' personal space, as approaching too close can provoke bison to charge.
