Genetic analysis combined with fossil evidence indicates that hominoids diverged from the Old World monkeys about 25 million years ago, near the Oligocene-Miocene boundary.The gibbons split from the rest about 18 mya, and the hominid splits happened 14 mya (Pongo), 7 mya (Gorilla), and 3-5 mya.

Fossils tell tale of last primate to inhabit North America before humans Science Daily - November 7, 2023
Paleontologists have shed light on the long-standing saga of Ekgmowechashala, based on fossil teeth and jaws found in both Nebraska and China. Ekgmowechashala is the last primate found in the fossil record before humans.
Paleontologists Find New Fossils of Enigmatic North American Primate called Ekgmowechashala who that lived in western North America during the Early Oligocene epoch, some 30 million years ago
Extinct giant ape directly linked to the living orangutan Science Daily - November 14, 2019
esearchers have succeeded in reconstructing the evolutionary relationship between a two million year old giant primate and the living orangutan. It is the first time genetic material this old has been retrieved from a fossil in a subtropical area. This allows the researchers to accurately reconstruct animal, including human, evolutionary processes way beyond the limits known today.
Tiniest ever fossil ape discovered in Kenya PhysOrg - November 7, 2018
When Stony Brook University anthropologist James Rossie began sifting through sediment in the Tugen Hills of Kenya during his first day of the dig, he didn't know he'd discover teeth from a previously undiscovered tiny ape species. The study shows that this belongs to a new species of ape-the smallest ever yet described, weighing just under 3.5 kilograms-from 12.5 million year old sites in the Tugen Hills, giving important clues about the unexplained decline in diversity of apes during the Miocene epoch.
First North American monkey fossils are found in Panama Canal excavation Science Daily - April 20, 2016
Seven fossil teeth exposed by the Panama Canal expansion project are first evidence of a monkey on the North American continent before the Isthmus of Panama connected it to South America 3.5 million years ago. The 21 million-year-old teeth were found in the Las Cascadas Formation during a five-year intensive fossil salvage project by field crews from STRI, the University of Florida and the New Mexico Museum of Natural History and Science. Most of the mammal groups represented in the Las Cascadas formation have North American origins, despite the fact that South America is much closer, supporting the idea that Central America and western Panama represented a long peninsula extending south from North America.
Fossils from heart of Amazon provide evidence that South American monkeys came from Africa PhysOrg - February 4, 2015
For millions of years, South America was an island continent. Geographically isolated from Africa as a result of plate tectonics more than 65 million years ago, this continent witnessed the evolution of many unfamiliar groups of animals and plants. From time to time, animals more familiar to us today - monkeys and rodents among others - managed to arrive to this island landmass, their remains appearing abruptly in the fossil record. Yet, the earliest phases of the evolutionary history of monkeys in South America have remained cloaked in mystery. Long thought to have managed a long transatlantic journey from Africa, evidence for this hypothesis was difficult to support without fossil data.
Divers find ancient monkey fossil BBC - July 22, 2010
Scientists have examined fossilized remains of a tiny, extinct monkey that were retrieved from an underwater cave in the Dominican Republic. The researchers believe the fossil to be around 3,000 years old, but say the species itself could be very ancient. This reveals clues about the origin of primates in the region. It also suggests that many ecologically valuable treasures could be discovered by the unusual field of "underwater paleontology".
Fossil links humans and monkeys BBC - July 14, 2010
Researchers have discovered the skull of a 29 million-year-old animal that could be a common ancestor of Old World monkeys and apes, including humans. It indicates that apes and Old World monkeys diverged millions of years later than previously thought, say the scientists. They described the primate, Saadanius hijazensis, in the journal Nature. Dr William Sanders from the University of Michigan, who led the research, said this was "an extraordinary find". The skull of this previously unknown species had some features that are shared by Old World monkeys and apes, including humans, today.
Ape ancestors brought to life by fossil skull of 'Saadanius' primate Guardian - July 14, 2010
The skull of a creature dubbed Saadanius helps to explain how ancient primates split into two groups Ð the Old World monkeys and the great apes, including chimpanzees, gorillas and humans
Newfound Primate Defies Classification Live Science - May 11, 2010
A newly discovered primate that lived in Africa some 37 million years ago is somewhat of a black sheep, evolutionarily speaking. It just doesn't seem to fit into the family tree, no matter how scientists look at it. The curiosity lies in the primate's unusual teeth, which don't match up with primate groups thought to be around at the same time. The find likely makes primate evolution on that continent more complicated, the scientists say.
Newfound Species Pushes Back Human-Ape Split Live Science - August 23, 2007
Recently unearthed fossils belonging to a new ape species suggest the lineages leading to humans and gorillas split several million years earlier than previously thought. Found in Ethiopia, the 10 million-year-old fossilized teeth resemble those of modern gorillas and appear specialized for eating fibrous foods such as stems and leaves.
Study: Chimps may have used 'hammers' 4,300 years ago BBC - February 13, 2007
Chimpanzees in West Africa used stone tools to crack nuts 4,300 years ago. The discovery represents the oldest evidence of tool use by our closest evolutionary relative. The skill could have been inherited from a common ancestor of chimps and humans, the authors say, or learnt from humans by imitation. Alternatively, humans and chimps may have developed tool use independently, the Proceedings of the National Academy of Sciences journal reports. Chimpanzees were first observed using stone tools in the 19th century. Julio Mercader and colleagues found stone tools at the Noulo site in Ivory Coast, the only known prehistoric chimpanzee settlement.
