What is "mahakala"

Mahākāla ( Sanskrit: Mahākāla, Devanagari: महाकाल) is a deity common to Hinduism, Buddhism and Sikhism. According to Hinduism, Mahākāla is the consort of Hindu Goddess Kali and most prominently appears in Kalikula sect of Shaktism. Mahākāla also appears as a protector deity known as a dharmapala in Vajrayana Buddhism, particularly most Tibetan traditions, in Tangmi (East Asian Esoteric Buddhism) and in Shingon (Japanese Esoteric Buddhism). He is known as Dàhēitiān (大黑天) in Chinese and Daikokuten (大黒天) in Japanese. In Sikhism, Mahākāla is referred to as Kal, who is the governor of Maya.

Mahakala (from Sanskrit, named for Mahakala, one of eight protector deities ( dharmapalas) in Tibetan Buddhism) is a genus of basal dromaeosaurid dinosaur from the Campanian-age (about 80 million years ago) Upper Cretaceous Djadokhta Formation of Ömnögovi, Mongolia. It is based on a partial skeleton found in the Gobi Desert. Mahakala was a small dromaeosaurid (approximately 70 centimeters long (28 in)), and its skeleton shows features that are also found in early troodontids and avialans. Despite its late appearance, it is among the most basal dromaeosaurids. Its small size, and the small size of other basal deinonychosaurians, suggests that small size appeared before flight capability in birds.
