Ordovician Period (488.3 to 443.7 mya) - diverse marine invertebrates, such as trilobites, became common - First green plants and fungi on land.

The Mars Reconnaissance Orbiter and the Mars Global Surveyor have found evidence that the Borealis basin in the northern hemisphere of Mars may have been created by a colossal impact with an object 2,000 kilometers in diameter at the time of the Late Heavy Bombardment. Approximately 4,000 million years ago, the earth was cool enough for land masses to form.
The supercontinent Rodinia was formed about 1100 million years ago, and it broke into several pieces that drifted apart 750 million years ago.
