In the last two decades, the number of phylogenetically informative anatomical characters
recognized in the appendicular skeleton of titanosaurian sauropod dinosaurs has increased�…

Titanosauriforms represent a diverse and globally distributed clade of neosauropod
dinosaurs, but their inter-relationships remain poorly understood. Here we redescribe�…

Background The axial skeleton of extinct saurischian dinosaurs (ie, theropods,
sauropodomorphs), like living birds, was pneumatized by epithelial outpocketings of the�…

Diplodocidae are among the best known sauropod dinosaurs. Several species were
described in the late 1800s or early 1900s from the Morrison Formation of North America�…

Titanosauriformes was a globally distributed, long-lived clade of dinosaurs that contains
both the largest and smallest known sauropods. These common and diverse�…

Two major ichnotypes of sauropod trackways have been described:“narrow-gauge,” in
which both manus and pes prints approach or intersect the trackway midline, and “wide�…

Smith and Lucas (1993) suggested that the human skeleton is “an overlooked but effective
visual aid.” We concur, not just for anatomical landmarks, but for the understanding of�…

Lower Cretaceous fossils from central Niger document the succession of sauropod
dinosaurs on Africa as it drifted into geographic isolation. A new broad-toothed genus of�…

At least two titanosaurian sauropod taxa have been discovered in the Early Cretaceous
Dinosaur Beds of northern Malawi, Africa. One of these, Malawisaurus dixeyi, is represented�…

Diplodocoidea includes some of the first well-known sauropod dinosaurs, including such
late 19th century and early 20th century discoveries as Apatosaurus, Diplodocus, and�…
