Creatures of the night! The world is a different place in the dark, and a whole array of organisms have adapted to being most active outside of daytime hours. This episode, we’ll explore the regular traits that allow nocturnal animals to get by, we’ll discuss some of the ways nocturnal evolution has shaped living species, and we’ll investigate which – if any – of these traits we can identify in the fossil record.

In the news: snake hormones, Australian amphibians, ancient microbes, and baby dinosaurs.

Some bones are only skin deep! In many species of reptiles, mammals, and amphibians, bones called osteoderms develop within the skin, serving as body armor, additional muscular support, display features, or any number of other functions. This episode, we explore the extraordinary diversity of osteoderm anatomy, we take a tour through the many and varied osteoderms of Earth history, and we investigate a long list of hypothesized functions for these unusual bones.

In the news: reptile skin, dinosaur quills, dinosaur bites, and cannibal snakes.
