Ramadapis sahnii was a primitive primate belonging to Sivaladapidae that existed around 11 to 14 million years ago (Early to Mid-Miocene). Only a mandible (a lower jaw bone) was found at the dig site, which was near Ramnagar in Udhampur district in Jammu and Kashmir specifically the lower Siwalik deposits. The jawbone indicates that Ramadapis resembled a modern day ring-tailed lemur. The early lemur was named after Ashok Sahni, who discovered the first sivaladapid in the Siwalik deposits. The mandible was only around one and a quarter inch long, which led scientists to assume that it was only around 11 pounds.

Ecology

The environment that Ramadapis sahnii lived in is highly disputed upon. It has been hypothesized to either be a woodland, a grassland with few trees, a humid tropical forest, and finally a sort of half grassland and woodland.

The Sivalik Hills, also known as the Shivalik Hills and Churia Hills, are a mountain range of the outer Himalayas that stretches over about 2,400 km (1,500 mi) from the Indus River eastwards close to the Brahmaputra River, spanning the northern parts of the Indian subcontinent. It is 10–50 km (6.2–31.1 mi) wide with an average elevation of 1,500–2,000 m (4,900–6,600 ft). Between the Teesta and Raidāk Rivers in Assam is a gap of about 90 km (56 mi). The literal translation of "Sivalik" is 'tresses of Shiva'. Sivalik region is home to the Soanian archaeological culture. The hills are well known for their Neogene and Pleistocene aged vertebrate fossils.

<i>Megaladapis</i> Extinct genus of lemurs

Megaladapis, informally known as the koala lemur, is an extinct genus of lemurs belonging to the family Megaladapidae, consisting of three species that once inhabited the island of Madagascar. The largest measured between 1.3 to 1.5 m in length.

<i>Archaeoindris</i> Extinct giant lemur

Archaeoindris fontoynontii is an extinct giant lemur and the largest primate known to have evolved on Madagascar, comparable in size to a male gorilla. It belonged to a family of extinct lemurs known as "sloth lemurs" (Palaeopropithecidae) and, because of its extremely large size, it has been compared to the ground sloths that once roamed North and South America. It was most closely related to Palaeopropithecus, the second largest type of sloth lemur. Along with the other sloth lemurs, Archaeoindris was related to the living indri, sifakas, and woolly lemurs, as well as the recently extinct monkey lemurs (Archaeolemuridae). The genus, Archaeoindris, translates to "ancient indri-like lemur", even though it probably became extinct recently, around 350 BCE.

Tupaiidae is one of two families of treeshrews, the other family being Ptilocercidae. The family contains three living genera and 19 living species. The family name derives from tupai, the Malay word for treeshrew and also for squirrel which tupaiids superficially resemble. The former genus Urogale was disbanded in 2011 when the Mindanao treeshrew was moved to Tupaia based on a molecular phylogeny.

<span class="mw-page-title-main">Kalari cheese</span>

Kalari or Kaladi is an Indian traditional ripened cheese product.This is a culinary dairy product invented by the nomadic tribal Gujjars centuries ago. It was crafted to address a specific need for the preservation of milk in a solid form during the sweltering summer months when these tribes venture into the hills with their livestock during bi-annual seasonal tribal migrations. Gujjars use this dairy food during the summer months to meet their nutritional requirements, and they sell it in markets in both divisions of Jammu and Kashmir to support their livelihood.

Indraloris is a fossil primate from the Miocene of India and Pakistan in the family Sivaladapidae. Two species are now recognized: I. himalayensis from Haritalyangar, India and I. kamlialensis from the Pothohar Plateau, Pakistan. Other material from the Potwar Plateau may represent an additional, unnamed species. Body mass estimates range from about 2 kg (4.4 lb) for the smaller I. kamlialensis to over 4 kg (8.8 lb) for the larger I. himalayensis.

<i>Enhydriodon</i> Extinct genus of carnivores

Enhydriodon is an extinct genus of mustelids known from Africa, Pakistan, and India that lived from the late Miocene to the early Pleistocene. It contains 9 confirmed species, 2 debated species, and at least a few other undescribed species from Africa. The genus belongs to the tribe Enhydriodontini in the otter subfamily Lutrinae.

Kapi is an extinct primate genus that lived in northern India about 13.8 to 12.5 million years ago during the Miocene. The only species, K. ramnagarensis, was described in 2020 and is known from a complete lower molar. The fossil was discovered in 2015 from Ramnagar, a town in Jammu and Kashmir, for which the species name was created. Though originally identified as member of the gibbons and popularised in the news as the oldest gibbon, it was later reassessed as those of pliopithecoid, a group of extinct Old World monkeys.

Vishnufelis is a fossil genus of feline (cat) containing only a single species, Vishnufelis laticeps. It was described by Guy Ellcock Pilgrim in 1932, based on the first cranial material of a cat found in Asia: a fragmented skull found in the Chinji Formation, which dates back to the middle Miocene.

Laomaki is a genus of adapiform primate that lived during the Early Oligocene in Asia, containing only the species Laomaki yunnanensis. It was described from a right maxilla fragment. Its molars and premolars are somewhat similar to those of Rencunius and Anthradapis respectively. Its placement within the family Sivaladapidae is uncertain; it has not been placed in a subfamily. It has been found at sites in Jammu and Kashmir and Yunnan, having lived around the time of the Eocene–Oligocene transition.
