Fuggedaboutit, research from a new study says. The rebuttal, published online today (July 25) in the journal Evolutionary Biology, shows that the T. rex "trio" study does not have the evidence to support its weighty ideas.

Few things are more enticing to a youngster than a muddy puddle. The children — likely four in all — raced and splashed through the soppy sloth trackway, leaving their own footprints stamped in the playa — a dried up lake bed. Those footprints were preserved over millennia, leaving evidence of this prehistoric caper, new research finds.

It ultimately helped researchers decipher ancient Egyptian hieroglyphics, whose meaning had eluded historians for centuries. But why did ancient scribes include three different kinds of writing, or scripts, on this iconic stone in the first place?

As a group, they have existed for at least 450 million years, surviving four of the "big five" mass extinctions, including the catastrophe that wiped out the nonavian dinosaurs 66 million years ago at the end of the Cretaceous period. For context, that makes sharks older than dinosaurs, which emerged roughly 240 million years ago, and even trees, which evolved on Earth around 390 million years ago. So how have sharks, as a group, survived this long? What are the secrets to their success?
