Ancient giraffe had 4 horns, short neck: Study
Spain-based archaeologists have analysed 9-million-year-old fossils of an extinct giraffe ancestor, which had four horns and a short neck. The discovery from Spain suggests the ancestors of the world's tallest mammal migrated out of Africa, like humans. Scientists said the newly discovered 'giraffid', which is the most complete fossil of its kind, may help trace their evolution to long necks.
