Younger Tyrannosaurus Rex bites were less ferocious than their adult counterparts

These fossil ammonites have lost their outer coating of shell, revealing the iridescent nacre beneath. Now extinct, ammonites were a group of marine mollusks that first appeared about 409 million years ago, persisting until the extinction event that wiped out the dinosaurs about 66 million years ago.

Using a method to better locate the source of weak tremors from regions with complex geological features, researchers found that many tremors originate from the shear zone, an area of high fluid pressure, in the Nankai Trough, which is schematically shown here with structures of tectonic plates and fault lines.

Making sense of commotion under the ocean to locate tremors near...
