Ostriches have been around for at least 60 million years according to archaeological findings. These earliest fossils were actually found in modern-day Mongolia.
They are truly pre-historic animals with many scientists who are of the opinion that ostriches are directly related to the dinosaur-era. This train of thought is based on the fact if you look at the anatomy of an ostrich it is very similar to those found of dinosaurs.
An interesting fact about ostriches is that their eyes are bigger than their brains. One eye-ball each weighs about 60 grams which is more than what the brain weighs – the brain weighs about 40 grams. The ostrich has the largest eye of any land animal and the eye measures about 5cm across. They have beautiful eyes which also has a practical purpose. Ostriches can see a moving object about the size of a big dog as far as 3km away during day-time and 50meters at night – truly impressive.
