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 1943, this specimen has been informally known in the literature as the 'Damparis sauropod' and 'French Bothriospondylus', and has been considered a brachiosaurid by most authors. If correctly identified, this would make the specimen the earliest known titanosaurifor
