The Complete History of the Earth: Ordovician Period

This week we finally make it to the next time in the History of the Earth series! During the Ordovician the life on Earth continues to to radiate out into many strange new forms. the Radiodonts that once ruled take on a new role, our ancestors start to gain better defences and several new predators appear and begin to shape what life will look like for many millions of years going forward. We are still a long way from the present day but every step we take forward shows us a world slightly more familiar than before!
