In Depth In 2006 the palaeontologists M. Sadiq Malkani described five new genera of titanosaur, Marisaurus, Balochisaurus, Sulaimanisaurus, Khetranisaurus and Pakisaurus, all from caudal vertebrae. From these only Marisaurus and Balochisaurus have had skull remains attributed to them, and only Marisaurus has (partial) rear limb bones attributed to the genus. Marisaurus and Balochisaurus were also … Read more
Uberabatitan: Research Database Titanosauria (Sauropoda) · Late Cretaceous (~70 MYA) · South America — Brazil (Uberaba, Araguainha Formation) Research Note: Uberabatitan was a titanosaurian sauropod from the Late Cretaceous of Brazil — an important taxon for understanding titanosaur diversity and evolution in the latest Cretaceous of South America. Research Finding Status Grade Year … Read more

In Depth One of the most common European sauropods of the Jurassic, Cetiosaurus is actually one of the most primitive. In more advanced sauropods the vertebrae are hollow as a weight saving feature, however Cetiosaurus has solid vertebrae which hint at its basal position in the evolution of sauropods. These solid vertebrae are similar to … Read more
Vulcanodon: Research Database Vulcanodontidae (Sauropoda) · Early Jurassic (~202–196 MYA) · Africa — Zimbabwe (Karoo equivalents) Research Note: Vulcanodon is one of the oldest known true sauropods, from the Early Jurassic of southern Africa. It was a relatively small sauropod compared to later giants, but established key anatomical features of the group — including columnar … Read more
In Depth Fossils of Sibirotitan were first found in Russia during the 1950s, but not named until the disarticulated bones were put together and finally given a name in 2018. At the time of the genus description, Sibirotitan was regarded as one of the oldest titanisauriform sauropod dinosaurs on the Asian continent. Further detail than … Read more
Bonitasaura: Research Database Titanosauria (Sauropoda) · Late Cretaceous (~83–71 MYA) · South America — Argentina (Cerro del Pueblo Formation) Research Note: Bonitasaura salgadoi was a titanosaurian sauropod from the Late Cretaceous Cerro del Pueblo Formation of Argentina. It is characterised by its relatively small body size and provides data on titanosaur diversity in Late … Read more
In Depth Savannasaurus is a genus of titanosaur that lived in Australia doing the Cretaceous. Hailing from the Winton Formation of Queensland, Savannasaurus would have been in the same habitat as other dinosaurs such as Diamantinasaurus, Austrosaurus and Wintonotitan. Savannasaurus seems to have been quite similar to Diamantinasaurus in form. Possible predatory threats to Savannasaurus … Read more
In Depth Zapalasaurus is another example of an early cretaceous era diplodocoid sauropod, a find significant in itself since many diplodocid genera are dated to the Late Jurassic. Further to its inclusion within the Diplodocoidea, Zapalasaurus has been included as a member of the Rebbachisauridae, a sub group of the Diplodocoidea that includes other Cretaceous … Read more
