It happened at about 300 million years ago, tens of millions of years before the Earth began to walk first dinosaurs. Alacanti lasted for almost 250 million years virtually unchanged, as evidenced by numerous findings of their fossilized skeletons in the layers of the earth's crust of different age. The reproduction of the skeleton were included in the above tutorial. And about 50 million years ago all Alacanti died out and disappeared from the face of the Earth.
