“…The selachian faunas exhibit strong similarities to those of the Maastrichtian of the Benguerir area (Ganntour Basin) and Oued Erguita (Souss Basin) of Morocco and of Egypt (Cappetta, 1987(Cappetta, , 1991Noubhani & Cappetta, 1997 Camoin et al 1993), Stratodus apicalis has also been reported from higher palaeolatitudes (above 30-40°N) in North America (Cope, 1872;Applegate, 1970;Case, 1979). The Syrian mosasaurid assemblage differs significantly from the boreal one from the northern Tethyan margin (see Bardet & Pereda Suberbiola, 1996) and shows similarities to the Middle East and North Africa faunas.…”

“…The vertebral centra are large, amphicoelous, constricted, with rounded articular surface borders, two lateral ridges that may be coalescent and a fused neural arch (see Arambourg, 1952). S. apicalis is a large open-sea predatory teleost known from the Campanian-Maastrichtian deposits of North America (Cope, 1872;Applegate, 1970;Case, 1979), West and North Africa (Arambourg, 1952;Dartevelle & Casier, 1959) and the Middle East (Avnimelech, 1957;Arambourg et al 1959;Raab, 1963;Chalifa & Lewy, 1991).…”

The marine vertebrate faunas from the Late Cretaceous phosphates of Syria

Marine vertebrate faunas from the latest Cretaceous phosphates of the Palmyrides Chain of Syria are described for the first time. Recent fieldwork in the phosphatic deposits of the Palmyra area (mines of Charquieh and Khneifiss, outcrops of Bardeh, Soukkari and Soukhneh) have yielded a rich and diversified assemblage of marine vertebrates, including more than 50 species of chondrichthyes, osteichthyes, squamates, chelonians, plesiosaurians and crocodilians. Selachians are the most abundant and diverse component of the faunas and are represented by at least 34 species of both sharks and rays. Actinopterygians include representatives of six families, the most common being the enchodontids. Squamates are known by six mosasaurid species and an indeterminate varanoid. Chelonians are represented by at least two bothremydids and two chelonioids. Finally, elasmosaurid plesiosaurs and indeterminate crocodilians are also present in the fossil assemblages. The difference in faunal composition observed between the sites is interpreted as being due to palaeoecological preferences related to the Hamad Uplift palaeostructure. The marine vertebrate faunas of Syria show close affinities with those of the latest Cretaceous phosphatic deposits of North Africa and the Middle East and are typical of the southern Tethyan realm. From a biostratigraphical point of view, the selachians are the only suitable material to provide elements of an answer to the long debated question of the age of the Syrian Senonian phosphates. They suggest an Early Maastrichtian age for most of the phosphates of the Palmyrides Chain.

“…Herman 1977Herman , 1982 and North America (e.g. Case 1978). The poor knowledge of pre-Late Cretaceous neoselachians in 1987 led to pre-Jurassc taxa being excluded from a study of diversification by Cappetta (1987b), and Berriasian to Barremian taxa being grouped together as a single data point.…”

The Neoselachii are a monophyletic group including all of the extant sharks and rays. They underwent rapid diversification throughout the Jurassic and Cretaceous, going from low-di versity assemblages of members of extinct orders in the Late Triassic to diverse assemblages con taining representatives of most extant clades by the end of the Cretaceous. The known fossil record of Mesozoic neoselachians is composed largely of isolated teeth, with articulated skeletal remains being known from a limited number of sites. The small tooth size of a large proportion of neose lachians, including almost all taxa in existence prior to the mid Cretaceous, led to very poor rep resentation in older publications. Their state of knowledge has improved dramatically since 1970 with the increased use of bulk sampling for isolated dental remains. Despite this, the high pro portion of Lazarus taxa from some stages suggests that the state of knowledge is still intermittent. Increase in assemblage diversity throughout the Jurassic and Cretaceous suggests that radiation events resulted in real and dramatic increases in diversity, and that the perceived diversification is not an artifact of poor knowledge. Cladogenesis inferred from the fossil record typically com pares more favorably with divergence predicted from molecular analysis, where Batoidea form a discrete basal clade, than with divergence predicted from morphological analysis, where Batoidea are considered a derived crown group within the Squalea. The timing of diversification events is discussed in light of the known fossil record, cladistically generated divergence times, and the paleoenvironmental distribution of faunas.

“…The marine Bearpaw Formation is Late Cretaceous (late Campanian-early Maastrichtian) in age and should produce useful aulopiform material, but fish material from this formation is very rare and to date no aulopiforms have been described (Gardiner, 1966;Case, 1978;Wilson and Bruner, 2004;Konishi et al, 2011). Gardiner (1966) reported only the occurrence of Cretalamna sp.…”
