Researchers have made a discovery about the largest dinosaurs to have existed. These giant herbivores were able to reproduce in high latitudes, far from the equator. A study on a set of fossilized eggs found that the dinosaurs developed a strategy to keep their eggs warm.

Most eggs and fragments of these dinosaurs have been found in lower latitude regions, where warmer temperatures would have made incubation easier. The dinosaurs in question were long-necked, small-brained herbivores that likely lived in herds and may have migrated long distances to nest.

Further details about this discovery are available from the source, including information about the specific type of dinosaur and the location where the fossilized eggs were found.
