Via Oswalt’s system of classification, I compare the tool-kits of wild and captive capuchins with those of Tanzanian chimpanzees and Tasmanian aborigines. The results indicate that capuchins have tool-kits that are smaller, and have lower ratios of artifacts to naturefacts, than those of Tanzanian chimpanzees and Tasmanian aborigines. Accordingly, Oswalt’s system can be used productively to assess the relative technological skills of monkeys versus those of apes and humans. 
The stone tools of capuchins (Cebus apella)
Capuchins produce lithic tools analogous to those produced by Oldowan hominids, as demonstrated by analysis of stone took by capuchins.
Pestle use and modification by tufted capuchins (Cebus apella)
Results provide further evidence of functional convergence for the use and modification of tools by tufted capuchins and are consistent with the view that extractive foraging is associated with the tool-using and toolmaking behavior of primates.
Spontaneous tool use in captive, free-ranging golden lion tamarins (Leontopithecus rosalia rosalia)
These are the first published observations of tool use by golden lion tamarins or any callitrichid in a non-experimental setting and provide further data supporting the theory of a link between extractive foraging and tool use.
Laterality of Hand Function in Tufted Capuchin Monkeys (Cebus apella): Comparison between Tool Use Actions and Spontaneous Non-tool Actions
Findings are consistent with views that hand preference is expressed more strongly for tool use than for non-tool activities, and that lateral bias for self-directed behavior is related to problem-solving skills in primates.

The prefrontal areas and cerebral hemispheres of the neotropical Cebus apella and its correlations with cognitive processes
Evidence is provided of correlations between anatomical particularities of the brain areas analyzed and some cognitive abilities previously described in these simians to provide evidence that the frontal lobe of C. apella is larger than that of other neotropical primates in the literature.

Many aspects of technological innovation can be represented using graph theory. This makes possible both quantitative and qualitative analysis of technologies and of technological innovation. This

Comparisons between wild chimpanzees in western Tanzania and aboriginal Tasmanians at the time of European contact show surprising similarity in the number of items in the tool kit, raw materials used, proportion of tools made versus those used unchanged, extent of complexity, type of prey, etc.

The development of tool use in a juvenile female is documented, along with the same female's novel use of a previously neglected object as a tool and the subsequent use of this object by the other members of the group.
The use of probing tools by tufted capuchins (cebus apella): evidence for increased right-hand preference with age
These results are consistent with hypotheses that in tasks that involve the use of tools, nonhuman primates exhibit strong lateral asymmetries at the individual level, a moderate left-hand bias at the population level, and increased bias with age toward use of the right hand.
The manufacture and use of tools by capuchin monkeys (Cebus apella).
The manufacture and use of tools in captive groups of tufted capuchin monkeys (Cebus apella) are described, providing further evidence that capuchins possess extensive manipulative propensities and emphasize the significance of the normal social environment in the full expression of these propensity.

In Parque Nacional Manuel Antonio, Costa Rica, an adult male Cebus capucinus was observed repeatedly hitting a venomous snake (Bothropsasper) with a branch. Initially a large dead branch overhanging
Tool use and predation of oysters (Crassostrea rhizophorae) by the tufted capuchin,Cebus apella appella, in brackish water mangrove swamp
It is suggested that this behavioural adaptability on mangrove resources is a key factor in the success of the species in this ecosystem.
Generative aspects of manipulation in tufted capuchin monkeys (Cebus apella).
Thirty-one tufted capuchins (Cebus apella) of 3 age groups devoted significant proportions of time to interaction with objects and substrates, and activity that combined an object with a substrate occurred often; activities that combined 2 portable objects were less frequent.
Hand preference in capuchin monkeys varies with age
Results are consistent with hypotheses that adult capuchin monkeys are biased toward use of their right hand for reaching and primates exhibit age-related differences in the strength and direction of hand preference in tasks that involve the use of tools.
A simple stone-tool technology in monkeys
Data provide further evidence for cross-species continuity in the tool-using and tool making abilities of primates and indicate that stone-tool technology may have evolved in the hominid lineage earlier than has been confirmed by the existing archaeological record.
Development of combinatorial manipulation in infant baboons (Papio cynocephalus anubis).
The results of this investigation demonstrate that infant baboons develop extensive manipulative propensities during the first postnatal semester, consistent with hypotheses that (a) creative recombination facilitates the acquisition of novel behavior patterns and (b) the development of combinatorial manipulation in baboons parallels theDevelopment of analogous abilities in human infants.
