Battle Axe Dinosaur 

A correspondent has sent me A LINK to an article in the New York Times. I am not sure whether this will work indefinitely but give it a go and let me know. The article is based on a paper in Nature. You can see an abstract HERE.

The remains of the beast were found in sub Antarctic Chile and is a species of the ankylosaurs, who are known for their heavy armour. This individual has been named as Stegouros elengassen and has an unusually shaped tail. It looks somewhat like a macuahuitl - a Mesoamerican club edged with obsidian. And a sort of battle axe!

Digital reconstruction of the unique tail weapon of the new species of armored dinosaur Stegouros elengassen. The tail was encased in pairs of dermal bones; a portion of the dermal bones has been digitally sliced away, to reveal the tail vertebrae within. Different colors signal physically separate bones; many dermal bones have fused into a single unit (liliac).CreditCredit...José Palma and Joao Francisco Botelho
