Marino Ice Age

The Marino Ice Age was an ice age in the Cryogenium . It is named after the town of Marino , a suburb of Adelaide in South Australia . The Marino Ice Age was one of at least three major ice ages in the Neoproterozoic era and marked the end of the Cryogenian about 635 million years ago. Several geological findings point to global glaciation of the planet and are considered to be evidence of a “ snowball earth ”.

The Marino Ice Age had a major impact on the development of life on earth. The first molecular traces of multicellular animals ( Metazoa ) date from the time during the Marino Ice Age. Fossil finds from the early Ediacarium following the Marino Ice Age , especially from the Doushantuo Formation , prove the development of multicellular animals.
