Kara crater
Template:Short description Template:Infobox terrestrial impact site
Kara is a meteorite crater in the Yugorsky Peninsula, Nenetsia, Russia.[1]
Heavily eroded, it is presently Script error: No such module "convert". in diameter, though it is thought to be originally Script error: No such module "convert". before erosion. Its age is estimated to be 70.3 ± 2.2 million years old (Late Cretaceous). Impactite outcrops located on the Baydarata Gulf (Baydaratskaya) shore north-east of the crater imply that the original size of the crater could have been the 4th largest on Earth.[2] The crater is not exposed at the surface.
The Kara crater lies in the southeastern end of the Yugorsky Peninsula, while the Ust-Kara site lies offshore, Script error: No such module "convert". east of the small Kara or Karskaya Guba inlet. It was formerly believed that these two sites were two separate craters and that they formed a twin impact structure from the Late Cretaceous. However, it seems that the Ust-Kara site does not exist as a separate site. Apparently, the suevite outcrops of the Ust-Kara impact structure are only a part of the Kara impact structure.[3]Script error: No such module "Unsubst".
