BACKGROUND Basal sauropodomorphs, or 'prosauropods,' are a globally widespread paraphyletic assemblage of terrestrial herbivorous dinosaurs from the Late Triassic and Early Jurassic. In contrast to several other landmasses, the North American record of sauropodomorphs during this time interval remains sparse, limited to Early Jurassic occurrences of a single well-known taxon from eastern North ...

Pliosaurids were a long-lived and cosmopolitan group of marine predators that spanned 110 million years and occupied the upper tiers of marine ecosystems from the Middle Jurassic until the early Late Cretaceous. A well-preserved giant pliosaurid skull from the Late Jurassic Kimmeridge Clay Formation of Dorset, United Kingdom, represents a new species, Pliosaurus kevani. This specimen is describ...

Abstract Different parts of the Lower Cretaceous Alam El Bueib (AEB) and Jurassic Khatatba source reservoir rock units in Faghur basin, like other basins north Western Desert, act as hydrocarbon sources reservoirs. In present study, well-log data from five wells Phiops field geochemical Neith S-2X well neighbor together with reflection 2D seismic thirty (30) lines have been utilized to evaluate...
