The six-mile-wide asteroid punched a one-way ticket toward extinction for all non-avian dinosaurs. Some 66 million years after the Chicxulub asteroid impact kickstarted the Cretaceous–Paleogene (K-T) extinction, scientists are still finding stunning evidence of its destruction.

Buried "megaripples" — some the size of five-story buildings — are helping scientists piece together the devastation following the impact that wiped out the nonavian dinosaurs.

Dozens of dinosaur footprints embedded in a boulder were found hiding in plain sight at an Australian school, according to researchers.

On Wednesday, scientists unveiled the discovery of fossilized dinosaur footprints on a rock slab that had been on display for 20 years at Biloela State High School in Queensland, Australia. The slab contains one of the strongest concentrations of dinosaur footprints ever observed in Australia,

For two decades, a big boulder sat in the corner of the main office at Bileola state high school in Queensland, Australia. Now, scientists discovered that the boulder boasts more than 60 fossilized dinosaur footprints from 47 different dinosaurs.
