Ordovician Period
Beginning over 488 Million years ago, 488.3 million to be exact, and ending 443.7 million years ago, it lasted just about 45 million years! Being oceanic planet at the time, means several marine species living in this time such as the creatures above in the picture.
The oceans at the time covered more than half the world, calling the different oceans things like the Panthalassic Ocean, Lapetus Ocean (which is created from several smaller oceans: Proto-Tethys, Paleo-Tethys, Khanty Ocean) and later the Rheic Ocean.
There was one giant land mass in the south pole of the world called Gondwana which was a supercontinent. But there were still independent countries like, Laurentia, Siberia, and Baltica, they were still independent until Laurentia and Baltica slowly moved closer together. As time passed more continents began to break off of Gondwana like Avalonia which formed the Rheic Ocean.
The Climate of the Ordovician Period was very hot at the beginning, reaching temperatures of 113 degrees fahrenheit just in the waters, because of the high levels of Carbon Dioxide gas it made a greenhouse effect making it very hot in this time period. Than a little over 20 million years later the temperatures became cooler, resulting in the decrease of water temperature being relatively close to the water temperatures we will see in the summer. Since the supercontinent Gondwana was located by the south pole, the continents that now make Africa and South America were covered by ice caps.
