PureScience: Dino asteroid struck in spring, killing northern hemisphere post-hibernation life more

From studying six fish fossils at Tanis, the famous site that documents mass floods from the Cretaceous-Paleogene extinction event, scientists have concluded that the asteroid impact that killed the dinosaurs and 75% of life occurred in the spring season. This was particularly deadly for animals in the Nothern Hemisphere that were coming out of hibernation, but autumn at the Southern Hemisphere and animals stepping into hibernation aided the recovery in this half of the world.
