NEW INFORMATION REGARDING THE HOLOTYPE OF SPINOSAURUS AEGYPTIACUS STROMER, 1915 (original) (raw)

Discovered over a century ago in Cretaceous rocks in Egypt, Spinosaurus aegyptiacus has remained an enigma, as all of the original associated bones were destroyed in a WW2 air raid and all that has come to light since are isolated specimens. In 2008, a partial skeleton was discovered by local collectors from the lower unit of the mid-Cretaceous Kem Kem sequence of Morocco. Further excavation at the site in 2013 resulted in the recovery of additional bones and teeth of a specimen that includes cranial bones, vertebrae from cervical, dorsal and caudal regions, manual bones, pelvic girdle, and hind limbs. Designated the neotype for S. aegyptiacus, the bones of this specimen and the most complete cranial pieces and postcranial bones of isolated individuals were computed tomography (CT)-scanned, surfaced, size-adjusted and combined to yield a digital skeletal model of an adult individual. The low, elongate skull has an expanded, hypersensitive snout end, labially procumbent interdigitati...

The sauropod Spinophorosaurus nigerensis was established by Remes et al. (2009) from two individu-als found in sediments of Middle Jurassic of Niger and was fi rstly considered as a non-eusauropod sauropod. Nevertheless, those authors noted several similarities between Spinophorosaurus and some Eurasian Middle Jurassic forms, such as Shunosaurus and mamenchisaurids. Spinophorosaurus is one of the most complete basal sauropods known to date, and its phylogenetic reassessment might add important information about the early phase of eusauropod evolution and Middle Jurassic eusauropod paleobiogeography. In fact, the reassessment of the Spinophorosaurus holotype, with the availability of previous unprepared elements, is providing valuable new information about its anatomy and new data for the morphological data matrices. Spinophorosaurus was fi rstly considered as a sister taxon of eusauropods (Remes et al., 2009), more prim-itive than Shunosaurus and some Middle Jurassic Gondwanic sauro...

Spinosaurids are a monophyletic clade of large-bodied, long-snouted theropod dinosaurs known from minimal skeletal material. in an effort to assist future research on this unu- sual clade, a catalogue of past spinosaurid discoveries is presented. database information includes specimen numbers, material identification, locality information, depositional environments, stratigraphic detail, generic or subclade assignment, tooth measurements, tooth placement, and detailed notes on the nature of the finds themselves when needed. previously reported biogeographic and faunal dispersal patterns suggest that spinosau- rids may eventually be found in north American strata, potentially having migrated from western europe in the early Cretaceous and eastern Asia over the Beringian isth- mus in the late Cretaceous. this database may be useful for predicting future points of spinosaurid discovery.
