Scientists have long been trying to reconstruct the appearance of dinosaurs. The tidbits they are able to piece together from fossils and other analysis are displayed in museums, educational materials, and media, lending to our idea of what these ancient creatures looked like.

A new study published in the journal Royal Society Open Science describes a new such clue, relating to the Diplodocus—a member of the Sauropod group of dinosaurs, known for their large size and long necks.
