Abstract This paper presents the facies and depositional environment of early Miocene Dam Formation, Eastern Arabian platform, Saudi Arabia. Deposition Formation (Fm.) was considered as a restricted shallow marine deposition. Few studies suggest role sea-level change in its deposition but were without decisive substantiation. Here, we describe high-resolution model Fm. under varying conditions....
Abstract The standard reconstruction of species Orbitoides d’Orbigny into a single lineage during the late Santonian to end Maastrichtian is based upon morphometric data from Western Europe. An irreversible increase in size embryonic apparatus, and formation greater number epi-embryonic chamberlets (EPC) with time, regarded as main evolutionary trends used discrimination. However, assemblages C...
Nephrolithiasis was incidentally diagnosed in 2 Arabian horses, a young foal and an adult mare, from Maybod, Yazd province, Iran. The foal had bilateral neophrolithiasis, as multiple sand like stones in renal papillary area. Large nephroliths were found in the left kidney of mare. Prominent composition of those nephroliths was magnesium ammonium phosphate. Risk factors and other aspects of neph...

The aim of this study was to investigate the incidence of radix entomolaris in mandibular first permanent molars in Saudi Arabian subpopulation. A total of 280 extracted mandibular first permanent molar were included in the study. The teeth were examined visually and the number of roots was recorded. The results showed that the majority of cases had two roots 93.9% (263 teeth), whereas the rema...
Sound speed in the oceans depends on temperature, salinity, and pressure and has large seasonal and spatial variations. Since temperature and salinity variations are large compared to pressure, we studied the relative importance of these two parameters on sound speed by analyzing the hourly profiles for one year (16 October 1994 – 22 October 1995) up to 250 m depth from the Woods Hole Oceanogra...
The paucity of data for the molossid bat Otomops throughout its range has hindered our ability to resolve the number of Otomops species present within the Afro-Malagasy region (including the Arabian Peninsula). This paper employed an integrative approach by combining morphometric (cranial morphology) and molecular (mitochondrial cytochrome b and D-loop sequences, nuclear intron sequences and mi...
Middle East respiratory syndrome coronavirus (MERS-CoV) is a zoonotic virus from camels causing significant mortality and morbidity in humans in the Arabian Peninsula. The epidemiology of the virus remains poorly understood, and while case-based and seroepidemiological studies have been employed extensively throughout the epidemic, viral sequence data have not been utilised to their full potent...
A recent molecular phylogeny of the Arid clade of the genus Hemidactylus revealed that the recently described H. saba and two unnamed Hemidactylus species from Sinai, Saudi Arabia and Yemen form a well-supported monophyletic group within the Arabian radiation of the genus. The name 'Hemidactylus saba species group' is suggested for this clade. According to the results of morphological compariso...
The response to the tropical cyclone Phyan, which developed in the eastern Arabian Sea during 9-11 November 2009, was rapid cooling of sea surface temperature (SST), enhancement of chlorophyll a and two-fold increase in net primary productivity (NPP). Cooling of SST was immediate in response to the strong wind-mixing, and the subsequent upward Ekman pumping sustained the cooling even after the ...
