2014 – Cetiosaurus installed as holotype

In 1869, Thomas Henry Huxley added Cetiosaurus to the list of dinosauria. It was the first sauropod ever described. But since its discovery, a whole mess of taxonomic and skeletal disputes have made it a difficult animal to pin down.

On this day in dinosaurs in 2014, Cetiosaurus oxoniensis was officially named the holotype species of the animal and the Mesozoic muddle was cleared up. The English “whale lizard” now has relatives and a place in the sauropod family tree.
