Long Island Scientist Discovers Dinosaur Neck Longer Than a School Bus. The neck measured to roughly 49 and a half feet long, or big enough to stretch across five parking spots — and then some By Greg Cergol, 4 News, New York, March 16, 2023 New Fossil Analysis Reveals Dinosaur With 50-Foot Neck SciTechDaily, March 17, 2023 The open access paper is: Moore, A.J., Barrett, P.M., Upchurch, P., Liao, C.C., Ye, Y., Hao, B. and Xu, X., 2023.

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.
