ANSWERS: 1=D Velociraptor and tyrannosaurus are known to have feathers on at least part of their bodies or when young. Yutyrannus (the star of the book) was covered in feathers, some 20cm long. 2=A&B The flying reptiles that lived at the time of the dinosaurs were not dinosaurs. It is possible that some dinos did develop limited flight later in history as dinosaurs evolved into birds. 3=A But these discoveries inform palaeontologists of which other dinosaurs probably had feathers too. 4=All of the above! Dinosaurs shared many behavioural and physical links with modern birds which isn’t surprising as birds evolved from them!
