Karoo chat Karoo chat The Karoo chat ("Emarginata schlegelii") is a small passerine bird of the Old World flycatcher family Muscicapidae. It is a common resident breeder in southwesternmost Angola, western Namibia and western South Africa. Its habitat is Karoo and desert scrub in the south, extending to the escarpment zone in the north. The first formal description of the Karoo chat was by the Swedish naturalist Johan August Wahlberg in 1855 under the binomial name "Erithacus schlegelii". The species was subsequently placed in the genus "Cercomela" introduced by Charles Lucien Bonaparte in 1856. It was moved to its current genus, "Emarginata",
Karoo (crater) of its craters exceeds the critical crater diameter. This would explain the crowding of giant craters, since none of these would result in global degradation. Indeed, if Karoo, at 33 km diameter, represents D and resurfaced the asteroid, then the 5 or more other giant impacts must have happened subsequently, which is highly unusual given that they are in fact almost just as large. Thus α = 1.33 from Fig. 2a is likely a lower limit on Mathilde’s attenuation. Karoo (crater) Karoo is an impact crater on the Asteroid 253 Mathilde, named for the Great Karoo Basin, a coal basin
