• How scales grow as dinosaurs grow can give us some information on how they lived

• Ceratosaurus grew more than 9 times faster than some of its fellow ceratosaurs
• The basal ornithopod Changchunsaurus was one of the slowest growing dinosaurs (that we know of)
• Maiasaura grew in a way that it needed a lot of parental care as a hatchling
• The hadrosaur Gryposaurus grew (mostly) isometrically (meaning everything grew at the same rate)
