Short answers, pulled from the story.
The gaur is the largest living bovid, a massive bovine that dwarfs all other wild cattle species in the Indian subcontinent and Southeast Asia. It stands up to 2 meters tall at the shoulder and weighs as much as 1,500 kilograms. This animal commands the forest floor with a presence that is both imposing and majestic.
On the 8th of January 2001, the first cloned gaur was born at Trans Ova Genetics in Sioux Center, Iowa. The calf was carried and brought successfully to term by a surrogate mother, a domestic cow. While healthy at birth, the calf died within 48 hours of a common dysentery, most likely unrelated to cloning.
Historically, the gaur occurred in Nepal, India, Bhutan, Bangladesh, Myanmar, Thailand, Laos, Cambodia, Vietnam, and China. Today it is regionally extinct in Peninsular Malaysia and Sri Lanka. The global population was estimated at a maximum of 21,000 mature individuals in 2016, with the majority of those existing in India.
In summer, the gaur feeds on bark of teak, fruit of golden shower tree, and the bark and fruit of cashew. They may also turn to available browse species and fibrous teak bark when green grass and herbaceous resources dry up. High concentrations of calcium and phosphorus in teak bark help satisfy both mineral and other food needs.
Only tigers and saltwater crocodiles have been reported to kill adult gaur. Leopards, dhole packs and large mugger crocodiles occasionally attack unguarded calves or unhealthy animals. A crocodile likely would need to be a mature adult male of more than 3 meters and 500 kilograms to make a successful attack on a healthy adult gaur.
