Palaeo After Dark

The gang discusses two papers that use fossil evidence to interpret physiology and functional morphology of extinct animals. First, we discuss a new study that suggests ichthyosaurs may have evolved blubber to help them regulate their temperatures. Second, we talk about a new study that uses robotic models to test how early tetrapods may have moved. Meanwhile, Amanda mixes caffeine and alcohol, Curt forgets Shane Black movies, and James tries to pull the ultimate mid episode twist.   Up-Goer Five (Amanda Edition): Today our friends talk about animals that are very big but not large, and how early animals with four feet walked.
