Stone hammering in natural conditions has been extensively investigated in chimpanzees and bearded capuchins. In contrast, knowledge of stone tool use in wild Old World monkeys has been limited to anecdotal reports, despite having known for over 120 years that Macaca fascicularis aurea use stone tools to process shelled foods from intertidal zones on islands in the Andaman Sea. Our report is the first scientific investigation to look at the stone tools used by these macaques. We observed they… 

Use-Wear Patterns on Wild Macaque Stone Tools Reveal Their Behavioural History

TLDR
This study is the first to demonstrate that quantitative archaeological use-wear techniques can accurately reconstruct the behavioural histories of non-human primate stone tools.

Habitual stone-tool-aided extractive foraging in white-faced capuchins, Cebus capucinus

TLDR
A population of white-faced capuchins in Coiba National Park, Panama who habitually rely on hammerstone and anvil tool use to access structurally protected food items in coastal areas including Terminalia catappa seeds, hermit crabs, marine snails, terrestrial crabs, and other items offers unique opportunities to explore the ecological drivers and evolutionary underpinnings of stone tool use.

Stone Anvil Damage by Wild Bearded Capuchins (Sapajus libidinosus) during Pounding Tool Use: A Field Experiment

TLDR
It is found that new pits were formed with approximately every 10 nuts cracked, (corresponding to an average of 38 strikes with a stone tool), and that adult males were the primary initiators of new pit positions on the anvil.

Stone tool use by wild capuchin monkeys (Sapajus libidinosus) at Serra das Confusões National Park, Brazil

Capuchin monkeys (Sapajus spp.) are proficient tool users, and the use of stone tools occurs in several populations, mostly to crack open encased foods. Two well-studied Brazilian populations of

Analysis of wild macaque stone tools used to crack oil palm nuts

TLDR
An initial description of hammerstones used by macaques to crack oil palm nuts, recovered from active nut-cracking locations on Yao Noi Island, Ao Phang Nga National Park, Thailand are presented.

Human activity negatively affects stone tool-using Burmese long-tailed macaques Macaca fascicularis aurea in Laem Son National Park, Thailand

Abstract Animal traditions can affect survival by improving how individuals use their environment. They are inherited through social learning and are restricted to small subpopulations. As a result,

Characteristics of hammer stones and anvils used by wild bearded capuchin monkeys (Cebus libidinosus) to crack open palm nuts.

TLDR
Wild capuchins provide a new reference point for interpreting early percussive stone tool use in hominins, and a point of comparison with chimpanzees cracking nuts.

The enhanced tool‐kit of two groups of wild bearded capuchin monkeys in the Caatinga: tool making, associative use, and secondary tools

TLDR
On three occasions, the monkeys used smaller stones to loosen bigger quartz pebbles embedded in conglomerate rock, which were subsequently used as tools, which could be considered the first reports of secondary tool use by wild capuchin monkeys.

Stone‐tool usage by Thai long‐tailed macaques (Macaca fascicularis)

TLDR
The discovery of stone‐tool usage by Thai long‐tailed macaques provides a new point of reference for discussions regarding the evolution of tool usage and the material culture of primates.

Wild capuchin monkeys (Cebus libidinosus) use anvils and stone pounding tools

TLDR
An exploratory investigation in an area where nut‐cracking by wild capuchin monkeys is common knowledge among local residents finds physical evidence that monkeys cracked nuts on rock outcrops, boulders, and logs (collectively termed anvils).

Capuchin Stone Tool Use in Caatinga Dry Forest

TLDR
Wild capuchin monkeys inhabiting dry forest were found to customarily use tools as part of their extractive foraging techniques, which consisted of twigs and sticks used to probe for insects and stones used for cracking and digging.
