Giant dinosaurs nested in cold climates using rotting vegetation to incubate eggs

Across millions of years of stone, fossilized eggs are now speaking from latitudes once thought too cold for the great sauropods to have nested. Paleontologists, including Canadian researchers, have discovered nesting sites farther south than any previously recorded, revealing that Earth's largest dinosaurs solved the impossible problem of incubation — too massive to sit upon their own offspring — by burying clutches in mounds of decomposing vegetation, letting the quiet chemistry of decay do what their bodies could not. The discovery does not merely extend a map; it redraws our understanding
