New fossils suggest dinosaurs thrived until asteroid strike 66M years ago

Sixty-six million years ago, an asteroid ended the age of dinosaurs — but whether it struck a dynasty in full flourish or one already dimming has long shaped how we understand catastrophe and decline. A 2025 study led by Andrew Flynn, drawing on fossils from New Mexico's San Juan Basin, now challenges the prevailing view: the evidence suggests dinosaurs were not fading but thriving, their communities rich and varied, right up until the moment of impact.
