Teeth from the Middle Jurassic of Morocco reveal the oldest turiasaurian sauropods from Africa [PDF]
Acta Palaeontologica PolonicaReadily identifiable based on their large, “spatulate” teeth with diagnostic “heart”-shaped crowns, turiasaurians are non-neosauropodan eusauropods known from varied Jurassic and Cretaceous formations across Laurasia and Gondwana.

Ten more years of discovery: revisiting the quality of the sauropodomorph dinosaur fossil record
Palaeontology, Volume 63, Issue 6, Page 951-978, November 2020., 2020 Abstract Spatiotemporal changes in fossil specimen completeness can bias our understanding of a group's evolutionary history. The quality of the sauropodomorph fossil record was assessed a decade ago, but the number of valid species has since increased by 60%, and 17% of the taxa from that study have since undergone taxonomic revision.

Why sauropods had long necks; and why giraffes have short necks [PDF]
, 2012 The necks of the sauropod dinosaurs reached 15 m in length: six times longer than that of the world record giraffe and five times longer than those of all other terrestrial animals.

Xenoposeidon is the earliest known rebbachisaurid sauropod dinosaur [PDF]
PeerJ, 2018 Xenoposeidon proneneukos is a sauropod dinosaur from the Early Cretaceous Hastings Group of England. It is represented by a single partial dorsal vertebra, NHMUK PV R2095, which consists of the centrum and the base of a tall neural arch.

Posture and mechanics of the forelimbs of Brachiosaurus brancai (Dinosauria: Sauropoda) [PDF]
Fossil Record, 1999 The posture and mechanics of the forelimbs of Brachiosaurus brancai were analysed with the help of biomechanical models. Peak forces in the joints due to acceleration of the fraction of body weight carried on the shoulder joints are critical in models ...

The Anatomical Record, EarlyView.Abstract A subadult Moschognathus whaitsi from the Eastern Cape Province, South Africa, was scanned using synchrotron radiation X‐ray computed tomography (SRXCT). Its subadult state allowed the cranial bones and teeth to be identified and individually reconstructed in 3D.
