Fossil evidence from New Mexico shows dinosaurs were still strong, diverse, and thriving before their sudden extinction 66 million years ago.

Humans have wiped out hundreds of species — with many more on the brink or experiencing large declines in population. Some scientists have argued that we have entered a “sixth mass extinction” event akin to the one that wiped out dinosaurs 66 million ...

The study offers the most recent data that challenges the long-held belief among paleontologists that dinosaur populations were declining globally prior to the asteroid impact.

Study warns that humans may be driving Earth toward a sixth mass extinction. The research shows species loss, but the future is in our hands.

The first analysis of recent extinctions across plants and animals finds that, contrary to previous studies, the rate at which many groups of organisms have gone extinct has declined over the last 100 years.

Few would doubt that more and more animals and plants are currently going extinct. One analysis comes to a different conclusion. This is not a cause for relief.

"The pace of change we’re seeing today is unlike anything we know of in the past 66 million years," said ecologist Jack Hatfield.
