what is the smallest primate in the world?

Answer 1

The smallest primate not extinct was the Philippine Tarsier at 4 inches and weighing about 60 grams. But recently the pigmy mouse lemur (microcebus myoxinus) was rediscovered in Madagascar. It weighs just 30 grams when fully grown. It is known to only inhabit the Kirindy Forest. I do not know of any pictures of this animal other than sketches.

Answer 2

A Fulbright scholar and former Miami Dolphins cheerleader, Mireya Mayor received her first grant to study the rare brown-bearded saki and white-faced saki in the unexplored areas of Guyana in South America when she was 23. She's also one of a handful of scientists to perform critical work on the highly endangered silky sifaka and Perrier's sifaka, whose habits remain a mystery to biologists. Recently, Mayor and fellow researcher Ed Louis discovered a new species of mouse lemur that may be the smallest primate in the world.

The smallest primate that ever lived is believed to be a species in the family Eosimiidae that lived 45 million years ago in humid rain forests in what is now China. The animal's size is estimated from fossils of ankle and foot bones discovered in 1996. One species is estimated to have weighed about 10 grams, and the other 15.

The primate was probably a tree-dweller that ate insects, fruit and nectar. It was eaten by owls–the recovered fossils may have come from bones in owl pellets.
