The Great Ape Dictionary Video Data Ark
<p>We study the behaviour and cognition of wild apes and other species (elephants, corvids, dogs). Our video archive is called the Great Ape Dictionary, you can find out more here <a href="https://greatapedictionary.ac.uk/">www.greatapedictionary.com</a> or about our lab group here <a href="https://www.wildminds.ac.uk/">www.wildminds.ac.uk</a> We consider these videos to be a data ark that we would like to make as accessible as possible. While we are unable to make the original video files open access at the present time you can search this database to explore what is available, and then request access for collaborations of different kinds by contacting us directly or <a href="https://greatapedictionary.ac.uk/video-resources/request-access/">through our website</a>.</p> <p>We label all videos in the Great Ape Dictionary video archive with basic meta-data on the location, date, duration, individuals present, and behaviour present. Version 1.0.0 contains current data from the Budongo East African chimpanzee population (n=13806 videos). These datasets are being updated regularly and new data will be incorporated here with versioning. As well as the database there is a second read.me file which contains the ethograms used for each variable coded, and a short summary of other datasets that are in preparation for subsequent version(s). If you are interested in these data please contact us. Please note that not all variables are labeled for all videos, the detailed Ethogram categories are only available for a subset of data. All videos are labelled with up to 5 Contexts (at least one, rarely 5). If you are interested in finding a good example video for a particular behaviour, search for 'Library' = Y, this indicates that this clip contains a very clear example of the behaviour.<br><br>March 17th 2025: Version 1.1.0 contains added data from the Bwindi mountain gorilla chimpanzee population (n=3537 videos).</p>

Fig. 18 in The Os Navicular of Humans, Great Apes, OH 8, Hadar, and Oreopithecus: Function, Phylogeny, and Multivariate Analyses
Fig. 18. Proximal views of the right cuboid and navicular of a human (A) and a common chimpanzee (B) in a closepacked position showing the contribution of the talocuboid angle (v) to the height of the transverse arch (h). In the closepacked position the small angle shown by chimpanzees results in a higher transverse arch than normally seen in humans. The human arch, however, unlike that of chimpanzees, exhibits a fixed height. Owing to a small, irregular, and often absent cuboid facet, the human talocuboid angle could not be accurately measured.
Fig. 17 in The Os Navicular of Humans, Great Apes, OH 8, Hadar, and Oreopithecus: Function, Phylogeny, and Multivariate Analyses
Fig. 17. Contribution of navicular torsion (v) and the frontal mesoectocuneiform angle (w) to the relative set of the ectocuneiform, mesocuneiform, and the talar facet in the closepacked position as seen in line drawings of an exploded right foot of a human (A) and a gorilla (B) from a dorsodistal view. High values of the frontal mesoectocuneiform angle in humans (w) do not result in marked opposition of the second and third metatarsals given metatarsal, ectocuneiform, and mesocuneiform torsion values which correct for the imparted set. Despite similar torsion values in humans and gorillas, the metatarsal, ectocuneiform, and mesocuneiform torsion all contribute to causing more marked opposition of the second and third metatarsals in gorillas. Marked talar torsion or large frontal mesoectocuneiform angles, are also associated to a high transverse arch (see text).
Fig. 16 in The Os Navicular of Humans, Great Apes, OH 8, Hadar, and Oreopithecus: Function, Phylogeny, and Multivariate Analyses
Fig. 16. Dorsal view of the exploded left tarsus and metatarsus of a pygmy chimpanzee in the closepacked position showing the contribution of the transverse mesoectocuneiform angle (w) and the transverse cuboectocuneiform angle (v) to the divergence of the second through fourth metatarsals. Correction of the talocuboid angle by the facet sets on the cuboid and ectocuneiform results in third and fourth metatarsals that are nearly alinged (y). A relatively low transverse mesoectocuneiform angle results in a second metatarsal that is divergent from the most lateral three (x) despite a partial correction of this set by the mesocuneiform.
Fig. 15 in The Os Navicular of Humans, Great Apes, OH 8, Hadar, and Oreopithecus: Function, Phylogeny, and Multivariate Analyses
Fig. 15. Contributions of the entoectocuneiform and sagittal taloectocuneiform angles (w and v respectively) to the relative set of the first through third metatarsal in closepacked position as seen in line drawings of the exploded left foot of a human (A) and of a gorilla (B) in medial view. The large sagittal taloectocuneiform angle in gorillas imparts a dorsiflexed set to the third metatarsal and is associated with a dorsiflexed talar head, i.e. small angle of talar neck inclination (Day and Wood 1968). The gorilla entoectocuneiform angle imparts a plantar set to the entocuneiform relative to the ectocuneiform and is associated with an abducted hallux, i.e. plantar divergence of the hallux relative to second (x) and third metatarsals (y). The human taloectocuneiform and entoectocuneiform angles are associated with a plantar flexed talar head (i.e., large angle of talar neck inclination), nearly aligned first to third metatarsals, and a longitudinal plantar arch. Due to a fixed transverse arch in humans, however, the long axis of the second and third metatarsals must have a more plantar inclination than the hallux, and the value of x and y are negative. Because the major axis of the navicular's talar facet is not necessarily held vertically, the sagittal taloectocuneiform and entoectocuneiform angles may also impart some degree of medial divergence to the hallux.
Fig. 14 in The Os Navicular of Humans, Great Apes, OH 8, Hadar, and Oreopithecus: Function, Phylogeny, and Multivariate Analyses
Fig. 14. Plot of mean canonical variate scores for studied taxa. All fossils are based on single samples. The actual Mahalanobis D for all of the canonical variates separating taxa is given as the value above each connecting line (table 11). Connecting lines represent a Minimum Spanning Tree (after Rohlf, 1997). Owing to a twodimensional projection, the actual lengths of the connecting lines on the plot represent only a fraction of the D values.
Fig. 13 in The Os Navicular of Humans, Great Apes, OH 8, Hadar, and Oreopithecus: Function, Phylogeny, and Multivariate Analyses
Fig. 13. Dendrograms of the studied taxa constructed using unweighted pair group method (Rohlf, 1997). Inset shows portion of dendrogram which differs when both Hadar naviculars are considered as a single sample.
Fig. 12. A in The Os Navicular of Humans, Great Apes, OH 8, Hadar, and Oreopithecus: Function, Phylogeny, and Multivariate Analyses
Fig. 12. A plot of the first two canonical variates with vectors representing the contribution of each of the measured variables to the scatter within and among measured taxa. Arrows point to fossils. Note the distinctiveness of H. sapiens, the uniqueness of Oreopithecus and the similarities of Hadar and African apes, of OH 8 and Homo, and of great ape species or subspecies within genera. The vectors representing the frontal mesoectocuneiform angle (EctMsFn) and the mediolateral diameter of the entocuneiform facet (EntFml) are nearly overlapping. Vector lengths are exagerated by a factor of ten, and owing to a twodimensional projection, are not proportional to their actual length. Eighty percent of the variance among means relative to the withingroup variance is summarized by the first two canonical variates (see figure 14 for plotted means of the first two canonical variates). Program written in Matlab version 5.1. This ''biplot'' is after Rohlf (1997); see Marcus (1993) for a discussion. The program and navicular data are available from one of us (LM). TalFlng = talar facet dorsoplantar (major axis) diameter, TalFwd = talar facet mediolateral (minor axis) diameter, EctFpd= ectocuneiform facet dorsoplantar diameter, EctFml= ectocuneiform facet mediolateral diameter, MesFdp= mesocuneiform facet dorsoplantar diameter, MesFml= mesocuneiform facet mediolateral diameter, EntFml= entocuneiform facet mediolateral diameter, EntFdp= entocuneiform facet dorsoplantar diameter, MaxLng= navicular maximum length, CuFdp= cuboid facet dorsoplantar diameter, CuFml= cuboid facet mediolateral diameter, TalFlDp= depth of talar facet along major axis, TalTrDp= depth of talar facet along minor axis; CubEcto = transverse cuboectocuneiform angle, EctMstr= transverse mesoectocuneiform angle, Tor= navicular torsion, EctMsFn= frontal mesoectocuneiform angle, TalEct= sagittal taloectocuneifrom angle, EctEmt= entoectocuneiform angle.

Fig. 1 in The Os Navicular of Humans, Great Apes, OH 8, Hadar, and Oreopithecus: Function, Phylogeny, and Multivariate Analyses
Fig. 1. Proximal (A), distal (B), lateral (C) and dorsal (D) views of the OH 8 navicular showing the measured lengths, and proximal (E), distal (F), lateral (G) and dorsal (H) views of a left gorilla navicular showing the measured angles; a = talar facet major axis (dorsoplantar) diameter, b = talar facet minor axis (mediolateral) diameter, c = ectocuneiform facet dorsoplantar diameter, d = ectocuneiform facet mediolateral diameter, e = mesocuneiform facet dorsoplantar diameter, f = mesocuneiform facet mediolateral diameter, g = entocuneiform facet mediolateral diameter, h = entocuneiform facet dorsoplantar diameter, i = navicular maximum length, j = cuboid facet dorsoplantar diameter, k = cuboid facet mediolateral diameter, l = depth of talar facet along major axis, m = depth of talar facet along minor axis; 1 = frontal talocuboid angle, 90° 2 = navicular torsion, 3 = frontal mesoectocuneiform angle, 4 = entoectocuneiform angle 5 = sagittal taloectocuneifrom angle, 6 = transverse mesoectocuneiform angle, 7 = transverse cuboectocuneiform angle. In all cases the lines chosen for angular measurements bisect facets into approximately equal halves. For comparative purposes the major bisecting axes of the talar head and cuneiform facets are referred to in the text as the dorsoplantar axes. In neither great apes nor humans do all these axes have a dorsoplantar orientation, but are held in varying inclination to a dorsoplantar axis according to talar head and navicular torison and the frontal mesoectocuneiform angle. The crosssectional area of the talar, ectocuneiform, mesocuneiform entocuneiform and cuboid facets are given by the products of a and b, c and d, e and f, g and h, and j and k, respectively. Relative crosssectional area for each facet is compared as a percentage of the sum of all of the navicular facets. The subtended angle of curvature and the radius of curvature of the talar facet along the dosoplantar (major) and mediolateral (minor) axes are given by 4 arctan(2l/a) and (l2 + a2/4)/ 2l, and 4 arctan(2m/b) and (m2 + b2/4)/2m, respectively.
