Karoo lark (as "Certhilauda albescens barlowi") to be subspecies of the Karoo lark. Karoo lark "The Karoo lark should not be confused with the similarly named Karoo long-billed lark." The Karoo lark ("Calendulauda albescens") or red-backed lark is a species of lark in the family Alaudidae. It is endemic to South Africa where its natural habitat is subtropical or tropical dry shrubland. The Karoo lark was originally classified in the genus "Alauda" and subsequently "Mirafra" and "Certhilauda", until moved to "Calendulauda" by the IOC in 2009. Not all authorities have followed this taxonomy change. Four subspecies are recognized: Formerly, some authorities considered
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
