Titanosaur fossil eggs reveal dinosaurs buried nests instead of brooding them
Paleontologists studying microscopic pores on fossilized Fusioolithus eggshells, linked to massive titanosaurs, concluded these giant dinosaurs could not incubate eggs by sitting on them due to their enormous size. Instead, the study led by Kohei Tanaka and Darla Zelenitsky suggests titanosaurs buried their volleyball-sized eggs in piles of decaying vegetation, similar to how modern crocodiles incubate their nests, even in surprisingly cool, far-from-equator climates.
