The earliest known titanosauriform sauropod dinosaur and the evolution of Brachiosauridae

Abstract: Brachiosauridae is a clade of titanosauriform sauropod dinosaurs that includes the well-known Late Jurassic taxa Brachiosaurus and Giraffatitan. However, there is disagreement over the brachiosaurid affinities of most other taxa, and little consensus regarding the clade’s composition or inter-relationships. An unnamed partial sauropod skeleton was collected from middle–late Oxfordian (early Late Jurassic) deposits in Damparis, in the Jura department of eastern France, in 1934. Since its brief description in 19… Show more

“…The slenderness index (SI; ratio of length of crown to mesiodistal width ( Upchurch, 1998 )) for YJDM 00008 ranges from approximately 2.30 to 3.56 ( Table 2 ). This range is similar to that observed in various brachiosaurids (2.2–2.68 in Vouivria ; 1.72–2.93 in Giraffatian ; 2.4–3.25 in Abydosaurus ; 2.3 in Soriatitan ) ( Chure et al, 2010 ; Mannion, Allain & Moine, 2017 ; Royo-Torres et al, 2017 ), Malawisaurus (3.3–3.5; Gomani, 2005 ), Sarmientosaurus (2.0–3.7; Martínez et al, 2016 ) and most non-lithostrotian somphospondylans, such as Europatitan (2.2; Torcida Fernández-Baldor et al, 2017 ), Euhelopus (2.2–3.3; Chure et al, 2010 ), Yongjinglong (1.65–3.93; Li et al, 2014 ), and Huabeisaurus (3.36–3.46; D’Emic et al, 2013 ). In Phuwiangosaurus and lithostrotians other than Malawisaurus , the teeth are markedly more slender than in YJDM 00008: for example, the SI exceeds 5 in Rapetosaurus ( Curry Rogers & Forster, 2004 ) and Pitekunsaurus ( Filippi & Garrido, 2008 ), and ranges from 3.3 to 6.3 in Phuwiangosaurus ( Chure et al, 2010 ), from 4.1 to 5.9 in the upper teeth of Tapuiasaurus ( Zaher et al, 2011 ; Wilson et al, 2016 ), and from 3.9–4.67 in Nemegtosaurus ( Wilson, 2005 ).…”

“…The distal dentary teeth of Giraffatitan are similar to the C2 teeth in the present study (ML 698, ML 2274 andML 2867), although the latter are less mesially inclined. This morphology observed for C2, intermediate between compressed chisel-shaped and more pencilshaped teeth, is also described for Europasaurus and Vouivria (Mannion et al 2017;Mocho et al 2017c;R egent et al 2024). A single C2 tooth (ML 2867) further differentiates itself from all other compressed chiselshaped teeth in the present study due to the presence of denticles along the mesial edge of the apex.…”
