Researchers who worked on the study also found that a global warming event occurring 55 million years ago was responsible for the evolution of modern seabird species, such as penguins and seagulls. The new findings provide a more comprehensive and refined perspective on the evolution of birds, sai...

Pathologic eggs have been documented in the amniote eggs of birds, turtles, and dinosaurs. These eggs occur either in the form of one egg within another egg, a condition known as ovum-in-ovo or multi-shelled eggs showing additional pathological eggshell
