The giraffe’s neck was not long from the beginning, but this animal has always preferred to use the butting method to defend its position, which is evidenced by the discovery of a fossil sample of a previously unknown type of giraffe that had what looked like a real brain shield.
This finding reinforces the hypothesis that the primary driver of the giraffe’s neck elongation was selection.
Discokeryx xiezhi was discovered in northern China, the first representative of a new species whose fossils date back to an animal that lived regarding 17 million years ago, according to a study whose results were published in the journal “Science” this week.
