The document provides information on measuring dinosaur footprints and trackways to determine characteristics of dinosaurs such as speed and size. It discusses measuring footprint length and stride length to calculate hip height, total length, and whether the dinosaur was walking, trotting, or running. Examples are given for various dinosaurs such as Velociraptor, Ultrasaurus, and Gallimimus. Formulas are presented for calculating hip height, relative stride length, dimensionless speed, and actual speed based on footprint and stride length measurements.
