Hello, I have inquired about a set of teeth-labelled as Dicraeosaurus, from South Tanzania. Tendaguru Formation. 1 - 3.5 cm x 1cm 2 - 4 x 1.5cm I had a look at the formation, and I see there are more than one diplodocid dinosaur from there. So, would a more accurate label be "diplodocid tooth", or can these teeth be identified down to Dicraeosaurus. Many thanks

A new sauropod-related paper is now available online: Philip D Mannion, Paul Upchurch, Daniela Schwarz, Oliver Wings; Taxonomic affinities of the putative titanosaurs from the Late Jurassic Tendaguru Formation of Tanzania: phylogenetic and biogeographic implications for eusauropod dinosaur evolution, Zoological Journal of the Linnean Society, , zly068, https://doi.org/10.1093/zoolinnean/zly068 Giraffatitan, Tornieria, and Dicraeosaurus are the best-known sauropods from the Tendaguru Formation, but the paper by Mannion et al. (2019) provides new insights into non-diplodocoid, non-brachiosaur sauropod diversity in Tendaguru Hill by assigning the long-enigmatic sauropod Tendaguria to Turiasauria, and formally recognizing a set of tail vertebrae previously assigned to Janenschia as the first mamenchisaurid from Africa, bearing the new binomial Wamweracaudia keranjei. Given the placement of Janenschia outside Neosauropoda, and the turiasaur and mamenchisaurid classifications of Tendaguria and Wamweracaudia respectively, it is quite apparent that more than one clade of non-neosauropod sauropods existed in East Africa during the Late Jurassic.

Good day to all of you. I have come to discover an amazing site in a remote location of the Serengeti: a dry river bed with hundreds of bones and what looks like stone tools too. The relevant authorities have been informed and i am still waiting for their visit. I have attached a few pics of what i found. Owing to the park rules, I may not pick up a few samples for proper photos. So i tried what i could Since we are not very far from Olduvai Gorge, i do believe this site to be of high importance. I would really appreciate any info on the pictured findings I am going to the site again this afternoon and will try to find bigger pieces and make also better pictures... Hoping to hear from you soon, Best regards, Okaroo

An interesting article about a new sauropod from Tanzania: http://phys.org/news/2014-09-species-titanosaurian-dinosaur-tanzania.html The discovery of a titanosaur from the Middle Cretaceous deposits in Tanzania is significant in many respects. First, it represents the third diagnostic titanosaur from Cretaceous sediments in sub-Saharan Africa. Second, it bolsters the hypothesis by Paul Sereno and colleagues that the breakup of Gondwana was a rather gradual one, so a number of titanosaurs known from South America may also have inhabited sub-Saharan Africa at a time when South America was slowly breaking away from Africa (the basal somphospondylian Angolatitan is of late Turonian age and also from sub-Saharan Africa, so it's not unreasonable to imagine titanosaurs populating South America and Africa in the Cenomanian and Turonian). Third, Rukwatitan is the first middle Cretaceous dinosaur from the Africa's Great Rift Valley. The non-titanosaur somphospondyl Wintonotitan and the lithostrotian Diamantinasaurus from Australia are of about the same age as Rukwatitan, so it's not implausible that some titanosaurs made it to Australia by immigrating to Africa, and then indirectly to Australia via Antarctica. With Rukwatitan, we are just beginning to appreciate the diversity of middle Cretaceous Gondwanan titanosaurs outside South America.
