Doughty et al. (2025) use a mechanistic model to study the relationship between seed size of flowering plants, their light environment and the size of animals in their environment, and predict a rapid increase of seed size during the Paleocene that eventually plateaued or declined, likely as a result of the appearance of large herbivores that opened the understory, reducing the competitive ...
Fossils from before the mass extinction have only been found around the Equator, but after the event fossils can be found all over the world.
