A recent field survey of the Middle–Upper Triassic (upper Anisian to lowermost Carnian) paralic marine deposits of the Jilh Formation in central Saudi Arabia has yielded large quantities of vertebrate fossils. These finds prompt a revision of the existing faunal list and include at least one novel stratigraphical occurrence for the Arabian Peninsula. The remains comprise sauropterygian marine reptiles (Psephosauriscus sp., Nothosaurus cf. tchernovi, Nothosaurus cf. giganteus, Simosaurus sp.), a lungfish (Ceratodus sp.), hybodontiform sharks (Hybodus sp.) and saurichthyform actinopterygians (Saurichthys sp.). Palaeobiogeographical assessment reinforces Tethyan affinities for the assemblage and reflects the close proximity of the Arabian region to the ‘Sephardic Realm’, a compositionally distinct circum-Mediterranean faunal province characterized by hypersaline Muschelkalk facies.

Triassic lungfish (Dipnoi) have been extensively documented from the Gondwanan continental and marine shelf deposits of Africa and Madagascar (Teixeira, 1949; Lehman et al., 1959; Beltan, 1968; Martin, 1979, 1981; Kemp 1996), Australia (Kemp, 1993, 1994, 1997a, 1998), India (Jain et al, 1964; Jain, 1968), and Antarctica (Dziewa, 1980). Numerous records also exist from Laurasian landmasses including Europe (Agassiz, 1838; Schultze, 1981), North America (Case, 1921) and central and eastern Asia (Liu and Yeh, 1957; Vorobyeva, 1967; Martin and Ingavat, 1982). By comparison, nothing is known of contemporary lungfish fossils from the Middle East. Thus, the recent recovery of a single tooth plate representing a new geographic occurrence of the genus Ceratodus Agassiz, 1838 from paralic marine deposits of the Jilh Formation, a latest Anisian to lower Carnian unit that crops out along the eastern margin of the Proterozoic Arabian Shield in central Saudi Arabia (Fig. 1), is significant because it provides the stratigraphically oldest record of dipnoans from the Arabian Peninsula.

AbstractMarine reptile remains occur in the Upper Cretaceous (lower Campanian to lower Maastrichtian) Adaffa Formation of NW Saudi Arabia. This is the first detailed report of late Mesozoic marine reptiles from the Arabian Peninsula. The fossils include bothremydid (cf. Taphrosphyini) turtles, dyrosaurid crocodyliforms, elasmosaurid plesiosaurs, mosasaurs (Prognathodon, plioplatecarpines) and an indeterminate small varanoid. The assemblage is compositionally similar to contemporary faunas from elsewhere in the Middle East/North Africa, and comprises taxa that are typical of the southern margin of the Mediterranean Tethys.

The plant diversity Sowth West of the Arabian Peninsula is considered to be very high due to its location, variation of climates, and geographical features. Generally, the Arabian Peninsula characterized by a very rich flora and is still not explored well. During the field survey of rare plant species, the authors collected a specimen of new taxa from the remote and inaccessible habitats in Jabal Ibrahim of the Asir region, Saudi Arabia. The plant was not reported so far in the flora of the Arabian Peninsula. The present paper deals with the record of one new plant species (Umbilicus tropaeolifolius Boiss) to the flora of Saudi Arabia and the Arabian Peninsula. The plant has a very small population range and very limited occupancy. The plant specimen was collected and later on identified and described with the available flora reference and with contact of a botanist.

Infection with the Peste des petits ruminants virus (PPRV) is a highly devastating viral infection of small ruminants. Dromedary camels live in close proximity of small ruminants in Arabian Peninsula (AP) and many other regions in the world. Little is known about the reasons behind continuous PPRV emergence in Saudi Arabia (KSA). Our objective was to test some dromedary camel population across the kingdom for the presence of specific PPRV antibodies. Our results show detection of specific PPRV antibodies (2.92%) in sera of tested dromedary camels from the eastern and south regions of the KSA. Our results suggest the exposure of dromedary camels to PPRV infection. Thus, dromedary camels may play some important roles in the sustainability of PPRV in the small ruminants across the AP. This is the first study examined the nationwide prevalence of the PPRV in dromedary camels in the KSA.

Architectural Tradition

In studies of Islamic architecture dealing with the earliest periods, a natural emphasis has fallen on the mosques of the Holy Cities of Arabia, the Ḥaramayn, whenever the architecture of the Arabian Peninsula has been discussed. In later periods, extensions and restorations in the Ḥaram in Mecca and the Mosque of the Prophet in al-Madīna have likewise been discussed, but until recent times, little has been said of any other Arabian mosques. As far as mosques beyond the Ḥaramayn are concerned, this neglect has been caused largely by their inaccessibility; but as a result of the imbalance, students of Islamic architecture have been left to judge Arabia by the Prophet's Mosque, which was only truly Arabian at its foundation, and the Ḥaram and the Ka'ba, which were always unique in Islam in terms both of religion and of architecture. As for later extensions and restorations of either mosque, these tell more of the development of Islamic architectural style and taste beyond the Peninsula than of any Arabian religious architectural tradition.

A New Species

Study of ground beetles of the Garf Raydah Nature Reserve, located in the Asir Mountains of southwestern Kingdom of Saudi Arabia (KSA) resulted in one species, Paussus abditus Nagel, sp. n. described as new to science. Thirteen species (21.3%) are reported as new country records and fifteen species (24.6%) are new records for Asir Province. Adult beetles were collected from 2013 to 2017. The determination of this material yielded a total of 61 species in 40 genera and 17 tribes belonging to nine subfamilies of Carabidae. The species richness represented approximately 36.1% of carabid species previously reported from KSA. The most species rich tribes were the Lebiini (20 species), the Harpalini (10 species), and the Bembidiini (6 species). The life form analysis of adults indicated 18 life form types that are grouped into three categories, Zoophagous (77.1%), Mixophytophagous (18.0%), and Myrmecophilous (4.9%). Zoogeographical analyses indicated that the Afrotropical (19.3%) and the Saharo-Arabian (19.3%) species dominate the carabid fauna of this region of KSA. Coryza cf. maculata (Nietner, 1856) is considered the only Oriental representative. Only one cosmopolitan species, Perigona nigriceps (Dejean, 1831), was collected. Eleven endemics were identified; six species are considered KSA endemics and five are Arabian Peninsula endemics.

The State of Qatar is a small peninsula located in the northeastern part of the Arabian Peninsula. It is classified as a subtropical desert with an extreme harsh climatic conditions in summer and mild winter. Information on Formicidae of Qatar as well as its insect fauna is poorly documented. So far only six species of Formicidae (ants) belonging to five genera have been recorded from Qatar. At least 300 ant species have been recorded from the Arabian Peninsula (Collingwood et al., 2011). For instance, Collingwood and Agosti (1996) reported a list of 265 ant species in Saudi Arabia. Moreover, Collingwood et al. (2011) published a list of 126 ant species in UAE and Sharaf et al. (2018a) recorded 123 ant species from Oman. This indicates a significant gap regarding our knowledge of the ant fauna and their diversity in Qatar. This study provides the first taxonomic survey of the ant fauna of Qatar. Ant specimens were collected by using aspirator, direct hand collection, litter sifting and pitfall traps during the period of April 2015 to March 2019 from 43 sites around the country. In the present study, 45 species are newly recorded for the ant fauna of the state of Qatar increasing the total number of ant species from Qatar to 51 species, including one additional subfamily, and 16 additional genera.

Stroke is a major cerebrovascular disease causes high mortality and morbidity in people around the world. Stroke is the third leading cause of death and the leading cause of adult disability. The largest country in the middle East, the Kingdom of Saudi Arabia (KSA), has been occupying approximately four-fifths of the Arabian Peninsula supporting a population of more than 28 million. Stroke is getting to be a quickly expanding issue and is the leading cause of illness and deaths in Saudi Arabia. It is clear that researches and studies regarding the incidence, prevalence and their sociodemographic properties of stroke is still incomplete due to lack of present studies being conducted in these specified areas. This article aims to discuss the aspect of stroke in Saudi Arabia beside the effects of modifiable and the non-modifiable risk factors from the literature published.

This study was aimed to investigate weeds kind in palm plantations. Date palm is the most chief economic crop in most countries of the Arabian Peninsula. Many factors, such as the presence of weeds, may cause a huge loss in the production of dates. Despite the severe damage caused by the presence of some weeds in agroecosystems, many weeds have many medicinal and economic uses. A total of 62 species were listed in palm Plantations in Tabuk and Al-Qassim Regions. A total of 51 species were listed in Tabuk Region (The number of unique species in the Tabuk Region reached 32 that not recorded in Al-Qassim Region. Also, 19 species were recorded in both of Tabuk and Al-Qassim Regions). A total of 30 weeds were listed in Al-Qassim Region (The number of unique species in the Al-Qassim Region reached 11 that not recorded in the Tabuk Region. In addition to, 19 species were recorded in both of Tabuk and Al-Qassim Regions). Zygophyllaceae was the most common family, the majority life span was annuals and the most common life form was therophyte in both Tabuk and Al-Qassim Regions. Data management and classification were achieved using PCORD (TWINSPAN and DCA analyses).
