The Middle East respiratory syndrome (MERS) is proposed to be a zoonotic disease; however, the reservoir and mechanism for transmission of causative agent, MERS coronavirus, are unknown. Dromedary camels have been implicated through reports that some victims exposed camels, in areas where disease has emerged antibodies virus, viral sequences recovered from association with outbreaks among humans. Nonetheless, whether mediate humans unresolved. Here we provide evidence geographic temporal...
Partial skeletons of two new fossil whales, Artiocetus clavis and Rodhocetus balochistanensis , are among the oldest known protocetid archaeocetes. These came from early Lutetian age (47 million years ago) strata in eastern Balochistan Province, Pakistan. Both have an astragalus cuboid ankle with characteristics diagnostic artiodactyls; R. has virtually complete fore- hind limbs. The important augmenting diversity Protocetidae, clarifying that Cetacea evolved Artiodactyla rather than...

ABSTRACT Complete Middle East respiratory syndrome coronavirus (MERS-CoV) genome sequences were obtained from nasal swabs of dromedary camels sampled in the Kingdom Saudi Arabia through direct analysis nucleic acid extracts or following virus isolation cell culture. Consensus MERS-CoV same with either template source and identical to published human sequences. However, contrast individual cases, where only clonal genomic are reported, detailed population analyses revealed presence more than...
Protocetidae are middle Eocene (49-37 Ma) archaeocete predators ancestral to later whales. They found in marine sedimentary rocks, but retain four legs and were not yet fully aquatic. Protocetids have been interpreted as amphibious, feeding the sea returning land rest.Two adult skeletons of a new 2.6 meter long protocetid, Maiacetus inuus, described from early Habib Rahi Formation Pakistan. M. inuus differs contemporary archaic whales having fused mandibular symphysis, distinctive astragalus...
Abstract The Saharo-Arabian Desert is one of the largest biogeographical barriers on Earth, impeding dispersals between Africa and Eurasia, including movements past hominins. Recent research suggests that this barrier has been in place since at least 11 million years ago 1 . In contrast, fossil evidence from late Miocene epoch Pleistocene episodic presence within interior water-dependent fauna (for example, crocodiles, equids, hippopotamids proboscideans) 2–6 , sustained by rivers lakes 7,8...
Biological and physical factors govern the distribution of fossils, but it is not always clear which more important. The preservation late Eocene vertebrates at UNESCO World Heritage site Wadi Al-Hitan, Western Desert Egypt, controlled primarily by processes responsible for sequence stratigraphic architecture on a siliciclastic shelf. Three types surface, each characterized taxonomically taphonomically distinct fossil assemblage, yield most known vertebrate fossils. Complete, partially...
Our understanding of locomotor evolution in anthropoid primates has been limited to those taxa for which good postcranial fossil material and appropriate modern analogues are available. We report the results an analysis semicircular canal size variation 16 species dating from Late Eocene Miocene, use these data reconstruct evolutionary changes adaptations over last 35 Ma. Phylogenetically informed regression analyses reveal three important aspects evolution: (i) earliest engaged relatively...
Recent advances in interdisciplinary archaeological research Arabia have focused on the evolution and historical development of regional human populations as well diverse patterns cultural change, migration, adaptations to environmental fluctuations. Obtaining a comprehensive understanding developments such emergence lifeways Neolithic groups has been hindered by limited preservation stratified assemblages organic remains, common challenge arid environments. Underground settings like caves...
Apex predators live at the top of an ecological pyramid, preying on animals in pyramid below and normally immune from predation themselves. are often, but not always, largest their kind. The living killer whale Orcinus orca is apex predator modern world oceans. Here we focus earlier predator, late Eocene archaeocete Basilosaurus isis Wadi Al Hitan Egypt, show stomach contents that it fed smaller whales (juvenile Dorudon atrox) large fishes (Pycnodus mokattamensis). Our observations, first...
The type specimen of Kinkonychelys rogersi, n. gen. et sp., is the first turtle skull to be described from pre-Holocene fossil record Madagascar. This specimen, a nearly complete cranium, along with several referred specimens (a series maxillae and partial lower jaw), was recovered Maastrichtian Maevarano Formation in Mahajanga Basin northwestern A braincase diagnostic characters Kinkonychelys, but differing position jaw articulation, formation foramen nervi facialis, number other...
Aegicetus gehennae is a new African protocetid whale based on partial skull with much of an associated postcranial skeleton. The type specimen, Egyptian Geological Museum, Cairo [CGM] 60584, was found near the base early-Priabonian-age (earliest late Eocene) Gehannam Formation Wadi Al Hitan World Heritage Site in Egypt. cranium distinctive having ventrally-deflected exoccipitals. vertebral column complete from cervical C1 through caudal Ca9, formula 7:15:4:4:9+, representing, respectively,...
Abstract Studies of modern carnivore accumulations bone (i.e., neo-taphonomy) are crucial for interpreting fossil in the archaeological and paleontological records. Yet, studies arid regions have been limited both number detailed taphonomic data, prohibiting our understanding bone-accumulating -modifying behavior dry regions. Here, we present a analysis an impressive carnivore-accumulated assemblage from Umm Jirsan lava tube Harrat Khaybar region, Saudi Arabia. The size composition...
Abstract Remingtonocetidae are Eocene archaeocetes that represent a unique experiment in cetacean evolution. They possess long narrow skulls, necks, fused sacra, and robust hind limbs. Previously described remingtonocetids known from middle Lutetian strata Pakistan India. Here we describe new remingtonocetid, Rayanistes afer , n. gen. sp., recovered to late interval of the Midawara Formation Egypt. The holotype preserves sacrum with four vertebral centra; several lumbar caudal vertebrae; an...
ABSTRACT The first diagnostic sirenian material from Madagascar and, more broadly, the pre-Pleistocene Cenozoic mammal recovered island is reported. Eotheroides lambondrano a new species of collected middle Eocene nearshore marine deposits in Mahajanga Basin northwestern Madagascar. consists nearly complete adult skull (including rostrum known for Eotheroides) and several portions pachyosteosclerotic ribs. Diagnostic features E. include: primitive upper dental formula 3.1.5.3, relatively...
Abstract Over the past decade, a growing interest has developed on archaeology, palaeontology, and palaeoenvironments of Arabian Peninsula. It is now clear that hominins repeatedly dispersed into Arabia, notably during pluvial interglacial periods when much peninsula was characterised by semiarid grassland environment. During intervening glacial phases, however, grasslands were replaced with arid hyperarid deserts. These millennial-scale climatic fluctuations have subjected bones fossils to...
