Rather than a juvenile of a known species, several fossilized bones represent a new species – and shed light on the question of whether dinosaurs were already in decline before disaster struck.
Impact cratering, caused by meteorites colliding with planetary surfaces, is one of the most fundamental cosmic processes.

Studying impact craters can broaden our understanding of the Earth’s evolution and life, as well as its possible future.

Resurrecting dinosaurs might not be so easy.
