Skull Cave is a small and shallow cave on the central heights of Mackinac Island in Michigan, United States. The cave was carved during the Algonquin post-glacial period by the waters of Lake Algonquin, a swollen meltwater ancestor of today's Lake Huron. [3] Skull Cave is primarily of interest for its historical associations.
The Hellfire Caves (also known as the West Wycombe Caves) are a network of man-made chalk and flint caverns which extend 260m underground.They are situated above the village of West Wycombe, at the southern edge of the Chiltern Hills near High Wycombe in Buckinghamshire, Southeast England.
Manot Cave (Hebrew: מערת מנות Me'arat Manot) is a cave in Western Galilee, Israel, discovered in 2008. [2] It is notable for the discovery of a skull that belongs to a modern human, called Manot 1, which is estimated to be 54,700 years old (U–Th dating of the calcitic crust on the Manot 1 calvaria and of speleothems in the cave).
One skull fossil, given the name Apidima 1, [4] shows a mixture of modern human and primitive features [7] and has been dated to be more than 210,000 years old, older than a Neanderthal skull ("Apidima 2") found at the cave, [7] which per some interpretations makes Apidima 1 the oldest proof of Homo sapiens living outside Africa, [8] [9] the ...
Shanidar I's skull and skeleton, c. 60,000 to 45,000 BCE. Iraq Museum. Shanidar 1 was an elderly Neanderthal male known as 'Nandy' to his excavators. He was aged between 30 and 45 years. Shanidar 1 had a cranial capacity of 1,600 cm 3, was around the height of 5 feet 7 inches (170 cm), and displayed severe signs of deformity. [29]
The skeletons were in remarkably good shape, though the weight of some 8 metres (26 ft) of sediments had crushed the skulls somewhat, particularly the fine bones of the face. Yet, de Villeneuve was reportedly struck by the prognathism of the skulls. [8] With the crushed nature of the skulls, such observation would have been tentative at best.
Iridium compounds are used as catalysts in the Cativa process for carbonylation of methanol to produce acetic acid. [92] [93] Iridium complexes are often active for asymmetric hydrogenation both by traditional hydrogenation. [94] and transfer hydrogenation. [95] This property is the basis of the industrial route to the chiral herbicide (S ...
Mossdale Caverns is a cave system in the Yorkshire Dales, England. It is about 5 kilometres (3.1 mi) north of Grassington, and east of Conistone, where Mossdale Beck sinks at the base of Mossdale Scar.
