New Information on Tataouinea hannibalis from the Early Cretaceous of Tunisia and Implications for the Tempo and Mode of Rebbachisaurid Sauropod Evolution.

The rebbachisaurid sauropod Tataouinea hannibalis represents the first articulated dinosaur skeleton from Tunisia and one of the best preserved in northern Africa. The type specimen was collected from the lower Albian, fluvio-estuarine deposits of the Ain el Guettar Formation (southern Tunisia). We present detailed analyses on the sedimentology and facies distribution at the main quarry and a revision of the vertebrate fauna associated with the skeleton.

Chronic intestinal bleeding because of aneurysm of superior pancreaticoduodenal artery: embolization during angiography.

A case of gastrointestinal hemorrhage, associated with abdominal pain, in an 8-year-old child because of an arterial malformation of duodenum is reported. Selective arteriography showed the presence of an aneurismatic lesion of superior pancreaticoduodenal artery. The leakage of the vascular lesion during examination permitted the embolization by microcoils and cyanoacrylate glue.
