The Future is Wild is a fictional documentary website about life on the Earth in 5, 100 and 200 million years. This is pretty cool stuff — lots of geographic surveys and ecological supposition, including invented far-future critters like this one:
4m tall, weighing 8 tonnes, with tentacles that extend to 3m and rhino-like skin, the megasquid is a formidable creature. It roams the northern forests of the planet 200 million years hence. All eight of its arms have become legs and look like thick columns, each are a 1/3 of a metre in diameter.
