Today I Learned …

Dinosaurs laid eggs in a fabulous variety of shapes and colors. According to research on the fossilized pigments from ancient eggs, dinosaurs laid eggs with shells in a rainbow of hues more than 145 millions years ago. Adding blues and greens and speckles to eggs was a way of making them less visible to predators. That’s because calcite, the white mineral that makes up hard eggshells, would glow vivid pink to a dinosaur’s eyes. (From National Geographic)
