The Touching Story of a Dinosaur Face

A reconstruction of the face of Daspletosaurus horneri, based on bone textures, reveals a host of details. (Illustration courtesy of Dino Pulerà) The eyes may be the window to the soul, but for paleontologists, reconstructing a dinosaur face opens doors into how it may have perceived and interacted with its environment — as well as some features it shared with distant evolutionary kin. Researchers report being able to put a face to the name of 75-million-year-old Daspletosaurus horneri, a newly described member of one of Dinosauria's most famous lineages, and discover the animal was the touchy-feely sort. Bones preserve a lot more than just the internal scaffolding of an animal. Certain textures, from tiny holes to striations to knobby bits can be clues to how and where muscles attached (and what size the muscles were), whether an animal had ornamentation and even the texture of its skin.
