Karoo Ice Age Karoo Ice Age The Karoo Ice Age, more commonly referred to as the Late Paleozoic Ice Age, from 360–260 million years ago (Mya) was the second major ice age of the Phanerozoic Eon. It is named after the tillite (Dwyka Group) found in the Karoo Basin of South Africa, where evidence for this ice age was first clearly identified in the 19th century. The tectonic assembly of the continents of Euramerica (later with the Uralian orogeny, into Laurasia) and Gondwana into Pangaea, in the Hercynian-Alleghany Orogeny, made a major continental land mass within the Antarctic region, and the closure of
Karoo north of the Great Karoo. Great locust swarms also frequently invaded or arose in the Great Karoo, and still occur from time to time today. The riverine rabbit, a critically endangered animal, lives exclusively in seasonal river basins and a very particular set of scrubland in the central semiarid region in the Karoo. It is hunted by falconiformes and Verreaux's eagles. Its numbers have been consistently lowering due to destruction of its habitat. They are unique relative to similar species through how they are polygamous and how each female can only produce one or two offspring per year. The introduction
