Photos by @paoloverzone / Ph.D. candidate Jasmina Wiemann transports a selection of bird eggs through the Yale Peabody Museum of Natural History in New Haven, Connecticut. Bird eggs, such as these from tinamous, get their color from pigments such as protoporphyrin and biliverdin. Some fossilized dinosaur eggs also preserve these two compounds, hinting at their hues. (The holes were used to drain contents and prevent the interior from rotting, so shells can be dried and curated in the collection.) Follow @paoloverzone for more photos and stories.
