The dueling dinosaurs were fossilized while apparently locked in battle.

‘Dueling dinos’ set off a long legal battle and a scientific debate

Science

In 2006, an amateur fossil hunter made an unprecedented find: two dinosaurs fossilized while apparently locked in battle. A court case followed over mineral versus surface rights, bringing into question the future of fossil discovery in the US.

Contrary to classic depictions of a tyrannosaurus rex, paleoartist Gabriel Ugueto says that the massive carnivores likely were covered in small feathers on the top of their bodies.

Turns out, dinosaurs probably had feathers. This artist is using science to draw more accurate pictures.
