The Middle Pleistocene, more specifically referred to as the Ionian stage, is a period of geologic time from ca. 781 to 126 thousand years ago.
|Australian Fossil Mammal Sites||The older fossils occur at Riversleigh, which boasts an outstanding collection from the Oligocene to Miocene, some 10-30 million years ago. The more recent story then moves to Naracoorte, where one of the richest deposits of vertebrate fossils from the glacial periods of the mid-Pleistocene to the current day (from 530,000 years ago to the present) is conserved.

|Carlsbad Caverns||The decoration of Carlsbad Cavern with stalactites, stalagmites and an incredible variety of other formations began more than 500,000 years ago after much of the cavern had been carved out.|
|Fraser Island||It is made up of sand that has been accumulating for approximately 750,000 years on volcanic bedrock that provides a natural catchment for the sediment which is carried on a strong offshore current northwards along the coast. (wiki)|
|Great Barrier Reef||The Great Barrier Reef Marine Park Authority (GBRMPA) considers the earliest evidence of complete reef structures to have been 600,000 years ago. (Wiki)|
|Hawaii Volcanoes||Mauna Loa has probably been erupting for at least 700,000 years. (Wiki)|
|Isole Eolie||The present shape of the Aeolian Islands is the result of volcanic activity over a period of 260,000 years. (Wiki)|
|Lena Pillars||Lena Pillars were formed some 400000 years ago. Nom file|
|Lenggong Valley||1.83 million years ago and again 200,000-100,000 years ago (AB ev)|
|Lopé-Okanda||400,000 years of almost continuous history (AB ev) - early stone age sites; the petroglyphs date from between 2,300 and 1,400 BP.|
|Lower Valley of the Omo||The oldest hominid remains are 200,000 years old (Ionian).|
|Mount Carmel Caves||500,000 years ago (AB ev)|
|Mount Etna||About 300,000 years ago, volcanism began occurring to the southwest of the summit (centre top of volcano) then, before activity moved towards the present centre 170,000 years ago. (Wiki)|
|Peking Man Site||Homo Erectus Pekinensis lived in the Middle Pleistocene Period, 700,000 to 200,000 years before modern times (AB ev)|
|Pitons Management Area||Qualibou, also known as the Soufrière Volcanic Centre is a 3.5 X 5 km wide caldera on the island of Saint Lucia that formed approximately 32-39,000 years ago. This eruption also formed the Choiseul Tuff which covers the south east portion of the island. The Pitons are two large lava domes that formed 200-300,000 years ago, some time before the formation of the caldera and since then other domes have filled the caldera floor. (wiki)|
|Sangay National Park||Sangay developed in three distinct phases. Its oldest edifice, formed between 500,000 and 250,000 years ago, is evidenced today by a wide scattering of material opening to the east, defined by a crest about 4,000 m (13,120 ft) high. (wiki)|
|Skocjan Caves||Vor einigen 100.000 Jahren stürzten Höhlendecken über dem Fluss ein. Dadurch entstanden die Einsturzdolinen Grosses Tal (Velika dolina, 165 m tief) und Kleines Tal (Mala dolina, 120 m tief). In der Sohle des Grossen Tals versickert die Reka endgültig. (wiki)|
|Tongariro National Park||In geological terms, the landforms of Tongariro National Park are comparatively young. These volcanoes are all less than 500,000 years old and still active.|
