Cimmeria (continent) Cimmeria (continent) Cimmeria was an ancient continent, or, rather, a string of microcontinents or terranes, that rifted from Gondwana in the Southern Hemisphere and was accreted to Eurasia in the Northern Hemisphere. It consisted of parts of what is today Turkey, Iran, Afghanistan, Tibet, Shan–Thai, and Malay Peninsula. Cimmeria rifted from the Gondwanan shores of the Paleo-Tethys Ocean during the Carboniferous-earliest Permian and as the Neo-Tethys Ocean opened behind it, during the Permian, the Paleo-Tethys closed in front of it.

Smallest organisms 0.46 mm. The smallest land snail is "Acmella nana". Discovered in Borneo, Malaysia, and described in November 2015, it measures only 0.7 mm. The previous record was that of "Angustopila dominikae" from China, which was reported in September 2015. This snail measures 0.86 mm. The smallest crustacean, and indeed the smallest arthropod, is the tantulocarid "Stygotantulus stocki", at a length of only . Eriophyid mites measure 125 to 250 μm in length. Adult males of the parasitic wasp "Dicopomorpha echmepterygis" can be as small as 139 μm long, smaller than some species of protozoa (single-cell creatures); females are 40% larger.
