Titanosauriform sauropod dinosaurs were once considered rare in the Upper Cretaceous of Asia, but a number of titanosauriforms from this stratigraphic interval have been discovered in China in recent years. In fact, all adequately known Cretaceous Asian sauropods are titanosauriforms, but only a few have been well studied, lending significance to any new anatomical information that can be extracted from Asia’s Cretaceous sauropod record. Here we give a detailed description of some titanosauriform bones recovered recently from the Upper Cretaceous Daijiaping Formation of Tianyuan County, Zhuzhou City, Hunan Province, southern China. The occurrence of this material in Hunan increases the known geographic range of titanosauriforms in eastern Asia. Although all of the specimens discussed in this paper can be assigned to Titanosauriformes at least tentatively, some bones display a limited number of features that are more typical of basal sauropods and/or derived diplodocoids, suggesting complex patterns of character evolution within Neosauropoda.

“…The stratigraphic position of the Spanish non-titanosauriform macronarian Aragosaurus (Sanz et al, 1987;Royo-Torres et al, 2014) has been the subject of debate (Canudo et al, 2012;Royo-Torres et al, 2014), but it has most recently been placed in the lower section of the Galve Formation and assigned a probable late Berriasian-early Valanginian age (Aurell et al, 2016). Stratigraphically younger Spanish deposits (late Hauterivian-early Aptian) record the presence of brachiosaurid (Soriatitan) and somphospondylan (Europatitan, Tastavinsaurus) titanosauriforms (Canudo et al, 2008;Royo-Torres et al, 2017b;Torcida Fernández-Baldor et al, 2017), as well as the rebbachisaurid Demandasaurus (Pereda-Suberbiola et al, 2003;Torcida Fernández-Baldor et al, 2011).…”

The Late Jurassic Tendaguru Formation of Tanzania, southeastern Africa, records a rich sauropod fauna, including the diplodocoids Dicraeosaurus and Tornieria, and the brachiosaurid titanosauriform Giraffatitan. However, the taxonomic affinities of other sympatric sauropod taxa are poorly understood. Here, we critically reassess and redescribe these problematic taxa, and present the largest phylogenetic analysis for sauropods (117 taxa scored for 542 characters) to explore their placement within Eusauropoda. Janenschia robusta has played a prominent role in discussions of titanosaur origins, with various authors referring at least some remains to Titanosauria, a clade otherwise known only from the Cretaceous. Re-description of the holotype of Janenschia, and all referable remains, supports its validity and placement as a non-neosauropod eusauropod. It forms a clade with Haestasaurus, from the earliest Cretaceous of the UK, and the Middle/Late Jurassic Chinese sauropod Bellusaurus. Phylogenetic analysis and CT scans of the internal pneumatic tissue structure of Australodocus bohetii tentatively support a non-titanosaurian somphospondylan identification, making it the only known pre-Cretaceous representative of that clade. New information on the internal pneumatic tissue structure of the dorsal vertebrae of the enigmatic Tendaguria tanzaniensis, coupled with a full re-description, results in its novel placement as a turiasaur. Tendaguria is the sister taxon of Moabosaurus, from the Early Cretaceous of North America, and is the first turiasaur recognised from Gondwana. A previously referred caudal sequence cannot be assigned to Janenschia and displays several features that indicate a close relationship with Middle-Late Jurassic East Asian mamenchisaurids. It can be diagnosed by six autapomorphies, and we erect the new taxon Wamweracaudia keranjei gen. et sp. nov. The presence of a mamenchisaurid in the Late Jurassic of southern Gondwana indicates an earlier and more widespread diversification of this clade than previously realised, prior to the geographic isolation of East Asia. Our revised phylogenetic dataset sheds light on the evolutionary history of Eusauropoda, including supporting a basal diplodocoid placement for Haplocanthosaurus, and elucidating the interrelationships of rebbachisaurids. The Tendaguru Formation shares representatives of nearly all sauropod lineages with Middle Jurassic-earliest Cretaceous global faunas, but displays a greater range of diversity than any of those faunas considered individually. Biogeographic analysis indicates that the Tendaguru sauropod fauna was assembled as a result of three main phenomena during the late Early and/or Middle Jurassic: (1) invasions from Euramerica (brachiosaurids, turiasaurs); (2) endemism in west Gondwana (dicraeosaurids, diplodocids); and (3) regional extinctions that restricted the ranges of once widespread groups (mamenchisaurids, the Janenschia lineage). Multiple dispersals across the Central Gondwanan Desert are required to explain the distributions ...

“…This almost global presence continues during Early Cretaceous, with several brachiosaurids in North America (Mannion et al, 2017) and Africa (McPhee et al, 2016). In Europe, they are only represented by the Iberian brachiosaurid Soriatitan (Royo-Torres et al, 2017a).…”

Galvesaurus herreroi is a sauropod from the Villar del Arzobispo Formation (late Kimmeridgian-early Tithonian), from the municipality of Galve (Teruel). Its phylogenetic relations have been long debated, so we carried out a phylogenetic analysis, using a new data matrix recently published by Carballido et al. (2017). The characters of Galvesaurus were coded on the basis of the redescription of the published remains and the description of two unpublished fossils: a right coracoid and a fragment of the right pubis. The results of the analysis suggest the inclusion of Galvesaurus in the clade Titanosauriformes, as a sister taxon to Lusotitan, these two taxa form part of the Brachiosauridae clade. Likewise, a stratigraphic study was undertaken, placing the Galvesaurus site in the lower part of the Villar del Arzobispo Formation, thus assigning the sauropod a late Kimmeridgian-early Tithonian age.
