She watched him swing the axe in a clean arc and thought that from this distance he could be any age. He had already turned forty when they met. It was early April, the fields and ditches coming green again after winter. Grass verges crept outward, thickening the arteries of narrow lanes.

Conceived and designed the experiments: LM PP. Performed the experiments: LM PP. Examining the cranial morphology of 28 skulls in lateral view and 36 squamosals of Nedoceratops hatcheri , Triceratops spp. Principal Component Analysis and cluster analysis confirmed different cranial morphologies. Torosaurus shape space is well separated from Triceratops , whereas Triceratops horridus and Triceratops prorsus partially overlap within Triceratops shape space. Linear regressions between shape and size suggest different ontogenetic trajectories among these taxa. We hypothesize that ontogeny drives cranial morphology with different patterns between Torosaurus and Triceratops.

Dinosaurs: A Very Short Introduction explains the latest findings in dinosaur research and the exciting scientific discoveries that have built up a picture of how dinosaurs looked, what they ate, and how they moved and interacted with each other. This new approach combines many areas of science, such as anatomy, genetics, forensics and engineering design, to piece together the evidence of how animal life evolved on earth, and why it did in the way that it did. Starting with ancient myths and the history of the discovery of dinosaurs, this VSI also discusses the role that informed speculation and luck has played in many key discoveries.
