where have miocene hominoid fossils been found?

Resemblance to the tooth shape of modern gorillas indicates that the 8-ma Samburu palate may be a potential candidate for membership in the African ape and human clade. In Comparative Primate Biology: Systematics, Evolution and Anatomy, ed. The first unambiguous occurrence of a hanging shoulder joint with a me- dially rotated humeral head similar to that of modern apes was discovered in. This finding, almost 1000 km south of Siwaliks has increased the geographic range of the genus,” says Dr Bhandari, who is also the corresponding author of the … The unique shape of the Kenyapithecus lower jaw symphysis is related to its specialized lower incisors. 24:237-56 Copyright O 1995 by Annual Reviews Inc.

The distal humerus of Kenyapithecus from Fort Ternan (KNM-IT 2751) resembles living hominoids in having a deep olecranon fossa and a broad trochlea with a well-developed median gutter and lateral trochlear keel (14, 42). 135.White TD, Suwa G, Asfaw B.

Click EDIT to add/edit tags. J. Hum. Although normally showing a strong deltopectoral crest and anterior curvature of the proximal humerus shaft in adults, juvenile Old World monkeys manifest a straight shaft and faintly marked deltopectoral crest. 19:39711.22, Andrews P. 1970. Insight into the possible origin of the modern great ape lower jaw shape, including the evolution of the simian shelf, is provided by a nearly complete subadult lower jaw of Kenyapithecus found at Maboko Island (Kenya) in 1988 (90). J. Well studied continental exposures occur in the North American Great Plains and in Argentina . The Kenyapithecus femur is long and slender, and is slightly longer than the humerus (88). Stratigraphy of the Lothidok Range, northern Kenya, and WAr ages of its Mio- cene primates. The most distinctive feature of the Kenyapithecus distal humerus is the strong posterior inclination of the medial epicondyle. Because canine robusticity and medial rotation are characteristic of the pitheciines Cebupithecia (119), Chiropotes, and Cacajao (66), they may represent other features related to the breaking open of tough seed coats by Miocene apes with thick-enameled molars. New York: Holt, Rinehart & Winston, Langdon JH. In contrast, hominoid fossils of similar ages have not been reported from Eastern Eurasia. 12:512-51 (Abstr. Nature, Andrews P. 1971. According to this classification, humans and their ancestors are relegated to a subdivision of the Hominidae, such as the Subfamily Homininae or Tribe Hominini. 1986. The bulk of this material consists of isolated teeth (Table 2), although several more complete craniodental and postcranial elements were also recovered. Nature 345:712-14, De Bonis L, Melentis J. Am. Prehist. 1). Strong forward inclination of the lower incisors was consequently lost, but the simian shelf was retained by most large-bodied genera and sewed as a preadaptation for the evolution of broad lower incisors in living great apes. New Sivapithecus humeri from Pakistan and the relationship of Sivapithecus and Pongo. Peabody Mus. 1902. On the relationships and adaptations of Kenyapithecus, a large-bodied hominoid from the middle Miocene of eastern Africa. The African apes are more closely related to members of another family (i.e. A new species of Dryopithecus from Gansu, China. As in semiter- restrial cercopithecoids such as Macaca, the medial portion of the entocunei- form facet of the hallucial metatarsal is flat and the peroneal tubercle is large, indicating that the big toe was habitually adducted (88).

J. Hum. RS Corruccini, RL Ciochon, pp. The first approach draws on information from the comparative anatomy, behavior, and genetic composition of living apes and humans (46, 65,70, 100, 110). A large number of mammalian fossils have been found in the Chiang Muan Mine, including the earliest known hominoid from the Miocene of Southeast Asia. 2. Hum. Univ. They mostly comprise large samples of isolated teeth, but there are also several partial or complete adult crania from Shihuiba and a single juvenile cranium from Yuanmou. Miocene primates from Kenya. The humerus shaft of Dryopithecus from St. Gaudens (Figure 9 in Refer- ence 73) has been claimed to possess a more weakly developed deltopectoral crest and less anterior flexion than the shaft of Kenyapithecus (18, 103). 1975. Nut. The diversity of apes seems to have declined during the Much new material of previously known large- bodied ape genera has also been discovered, e.g. Some Miocene large-bodied apes, such as Kenyapithecus and Sivapithecus, resemble orangutans and hominids in that both have thick molar enamel. A proximal ulna of Kenyapithecus exhibits a longer and more posteriorly reflected olecranon process than is characteristic of modern hominoids (88). Sci. It was further suggested that the dietary shift from soft fruit and leaves to hard fruit and grass seeds, and from arboreal to terrestrial substrates in African apes and humans, was related to the spread of increasingly more open country habitats since the early Miocene (13). USA 58:14248, 112.Schultz AH. The first appearance of these great ape-like features in the African middle Miocene is correlated with an adaptive shift to consumption of hard fruit and nuts.

In addition, the minimal development of the hamulus of the Sivapithecus hamate (another wrist bone) is completely unlike the large, hook-like hamulus of modern hominoids, including gibbons (118).

J. Phys. The large-bodied hominoid from Uganda dates to at least 20.6 million years ago and thus represents the oldest known hominoid sharing these derived … FS Szalay, pp. Without an understanding of these basic adaptive parameters, broad paleoenvi- ronmental reconstructions provide virtually no information concerning the ecological interactions of Miocene apes within their physical and biotic envi- ronments.

Finally, hominid origins can be reconstructed by working forward in time from the perspective of Miocene hominoid fossils. Fossils from a large-bodied hominoid from early Miocene sediments of Uganda, along with material recovered in the 1960s, show features of the shoulder and vertebral column that are significantly similar to those of living apes and humans. 1983.

Re- duction of the molar cingulum is considered to be a derived trait because all early Miocene apes, including Proconsul and Afropithecus, possess well- marked cingula. Evol. Palae- ontol. Kenyapithecus shares a broad humeral trochlea and prominent lateral trochlear keel with Proconsul, Sivapithecus, Dryopithecus, and Oreopithecus in addition to modern hominoids (93, 95, 102, 120). A well preserved and remarkably complete skeleton of the springhare Megapedetes pentadactylus was also prepared out of a block from a small excavation in area 1. However, upper jaws of Kenyapithecus from Baragoi (57) and Dryopithecus from Rudabanya (132) resemble Rangwapithecus and some individuals of Hylobates and Gorilla in that the incisive opening is of moder- ately large caliber and the front edge of the palatal process of the maxilla is not overridden by the back edge of the subnasal alveolar process.

Although the transition from life in the trees to life on the ground is deeply embedded in models of human evolution as a primary motive force in human origins, among African large-bodied apes this change occurred approximately 15 million years ago and is not directly linked with the advent of bipedalism or colonization of grassland environments 3-4 million years ago. In contrast, living hominoid humerus shafts are straight. Evol. Preliminary notes of new man-like apes from India. Subnasal al- veolar morphology and the systematic po- sition of Sivapithecus.

The facial skeletons of Afropithecus from the northern Kenyan site of Kalodirr (74) and of Dryopithecus from Can Llobateres in Spain and Rudabanya in Hungary share well-developed supraorbital costae and frontal trigons with Sivapithecus and Pongo, indicating that these features were primitive retentions from the common ancestor of large-bodied Miocene hominoids (29, 30).

Vert. For example, the early Miocene hominoid Proconsul was viewed as an ancestor of the gorilla and chimpanzee (35, 98, 116, 128). Am. Given that gibbons share derived limb bone and vertebral column adaptations with great apes, the large-bodied hominoids of the middle and late Miocene are no more closely allied to great apes than they are to gibbons. The capitate (a wrist bone) of Sivapithecus is fundamentally different from that of modern hominoids at its proximal end, indicating a mid-carpal joint unlike that of modern apes and humans (105). 21: 295-306, Conroy GC.
