A unique Middle Miocene European hominoid and the origins of the great ape and human clade
TLDR
A male partial face with mandible of a previously undescribed fossil hominid, Anoiapithecus brevirostris gen. et sp.
The evolution of human and ape hand proportions
TLDR
High levels of hand disparity among modern hominoids are revealed, which are explained by different evolutionary processes: autapomorphic evolution in hylobatids (extreme digital and thumb elongation), convergent adaptation between chimpanzees and orangutans (digital elongation) and comparatively little change in gorillas and hominins.
Orang-like manual adaptations in the fossil hominoid Hispanopithecus laietanus: first steps towards great ape suspensory behaviours
TLDR
The retention of powerful grasping and palmigrady suggests that the last common ancestor of hominids might have been more primitive than what can be inferred on the basis of extant taxa, suggesting that pronograde behaviours are compatible with an orthograde bodyplan suitable for climbing and suspension.
First partial face and upper dentition of the Middle Miocene hominoid Dryopithecus fontani from Abocador de Can Mata (Vallès-Penedès Basin, Catalonia, NE Spain): taxonomic and phylogenetic…
TLDR
Anatomical and morphometric analyses indicate that the new specimen shows a combination of lower facial features-hitherto unknown in Miocene hominoids-that resembles the facial pattern of Gorilla, thus providing the first nondental evidence of gorilla-like lower facial morphology in the fossil record.
Pierolapithecus and the functional morphology of Miocene ape hand phalanges: paleobiological and evolutionary implications.
TLDR
The results indicate that the manual phalanges of Miocene apes are much more similar to one another than to living apes, and agree with the view that hominoid locomotor evolution largely took place in a mosaic fashion.
The femur of Orrorin tugenensis exhibits morphometric affinities with both Miocene apes and later hominins.
TLDR
The results indicate that both hominin and modern great ape femora evolved in different directions from a primitive morphology represented by some fossil apes, consistent with femoral shape similarities in extant great apes being derived and homoplastic.
A Partial Skeleton of the Fossil Great Ape Hispanopithecus laietanus from Can Feu and the Mosaic Evolution of Crown-Hominoid Positional Behaviors
TLDR
The combination of quadrupedal and suspensory adaptations in this Miocene crown hominoid clearly evidences the mosaic nature of locomotor evolution in the Hominoidea, as well as the impossibility to reconstruct the ancestral locomotor repertoires for crown hom inoid subclades on the basis of extant taxa alone.
Earliest modern human-like hand bone from a new >1.84-million-year-old site at Olduvai in Tanzania
TLDR
The discovery of OH 86 suggests that a hominin with a more MHL postcranium co-existed with Paranthropus boisei and Homo habilis at Olduvai during Bed I times.
Locomotor inferences in Pierolapithecus and Hispanopithecus: Reply to Deane and Begun (2008).
New dental remains of Hispanopithecus laietanus (Primates: Hominidae) from Can Llobateres 1 and the taxonomy of Late Miocene hominoids from the Vallès-Penedès Basin (NE Iberian Peninsula).
TLDR
12 teeth of the fossil great ape Hispanopithecus recovered in 2011 from the locality of Can Llobateres 1 are reported, confirming that hominoid-bearing fossiliferous layers from CLL1 are not exhausted and additional excavations at this site are promising for the discovery of additional remains of H. laietanus in the near future.
