A new hypothesis to explain the long neck of the giraffe

By studying all the vertebrae of this fossilnamed Discokeryx xiezhi, the researchers were able to discover that it is indeed a giraffoidea, that he has a very thick and bony disc on his head, which suggests that there was an attack with headbutts between males. They also found that the cervical vertebrae are extremely hard compared to other fossils.

They remodeled all the vertebrae in 3 dimensions to observe by digital simulation what happens when there is a headbutt between males. This specific joint head-neck is quite special and extremely complex, the most complex known to date.

They were able to demonstrate that the blow of the head given is particularly violent, thanks to this bony disc on the skull of the animal, and that thehen the size of the vertebrae increases, the impact is increased.
