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… Expand
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. Expand
There Is More than One Way to Crack an Oyster: Identifying Variation in Burmese Long-Tailed Macaque (Macaca fascicularis aurea) Stone-Tool Use
TLDR
Variation in patterns of percussive stone-tool use on coastal foods by Burmese long-tailed macaques from two islands in Laem Son National Park, Ranong, Thailand is explored, compared to other stone-using primates, and implications for further research are discussed. Expand
Use of stone hammer tools and anvils by bearded capuchin monkeys over time and space: construction of an archeological record of tool use
Abstract Wild bearded capuchins (Sapajus libidinosus) in the cerrado (seasonally dry savannah-like region) of Brazil routinely crack open several species of palm nuts and other hard encased fruitsExpand
Sex differences in the stone tool‐use behavior of a wild population of burmese long‐tailed macaques (Macaca fascicularis aurea)
TLDR
It was found females used stones more often while feeding and used smaller tools than males, whereas males processed unattached foods more than females, and it was unclear which sex was overall more proficient at stone tool use. Expand
Use-wear and residue analysis of pounding tools used by wild capuchin monkeys (Sapajus libidinosus) from Serra da Capivara (Piauí, Brazil)
Abstract Bearded capuchin monkeys (Sapajus libidinosus) from Serra da Capivara National Park (Brazil), perform the widest range of activities using stone tools of all the non-human tool-usingExpand
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.

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. Expand
Stone tool use in wild bearded capuchin monkeys, Cebus libidinosus. Is it a strategy to overcome food scarcity?
TLDR
To determine whether tool use varied in relation to food availability in bearded capuchin monkeys, anvil and stone hammer use was recorded in two sympatric wild groups, and climatic variables and availability of fruits, invertebrates and palm nuts were assessed. Expand
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. Expand
Optional tool use: The case of wild bearded capuchins (Sapajus libidinosus) cracking cashew nuts by biting or by using percussors
TLDR
It is suggested that success at opening cashews with a tool 1–2 years earlier than they succeed at cracking more resistant palm nuts may support the monkeys' persistent efforts to crack palm nuts. Expand

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. Expand
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. Expand
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. Expand
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). Expand
Selection of Effective Stone Tools by Wild Bearded Capuchin Monkeys
TLDR
It is demonstrated that capuchins, which last shared a common ancestor with humans 35 million years ago, faced with stones differing in functional features (friability and weight), choose, transport, and use the effective stone to crack nuts. Expand

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. Expand
