Dinosaur of the day Valdosaurus, an iguanodont that lived in the Early Cretaceous.

Some of the topics we discuss in this episode are:

• "Display arenas" showing potential courtship ceremonies in Cretaceous rock
• Two oviraptorosaur tails that may show differences between males and females (males with tail-shaking muscles)
• Dinosaur "dance floor" of tracks that seem to show stopping and crouching behaviors
• A simulation of the enormous sauropod Argentinosaurus walking
