In Depth Unfortunately at the time of the genus description the only fossils of Austroposeidon that we have are some vertebrae. However, comparison to other similar dinosaurs has led to realistic size estimates for this dinosaur of about twenty-five metres in length. Although not the biggest dinosaur, this does make Austroposeidon at the time of … Read more
In Depth Sonorasaurus may look like an atypical brachiosaurid dinosaur (as in similar to the famous Brachiosaurus), but the genus actually represents the first known example of a brachiosaurid dinosaur in North America during the Cretaceous, specifically around the early/late Cretaceous boundary. This is yet further evidence that counters the now outdated theory that the … Read more
In Depth Astrodon has been a troublesome genus of sauropod dinosaur, partly because of the lack of complete remains for the genus which was initially primarily named from the teeth. Astrodon also has an uncertain relationship with the genus Pleurocoelus, with some authors considering the two to be synonymous, to just some species of Pleurocoelus … Read more
In Depth Pellegrinisaurus is a genus of titanosaur that lived in South America during the late cretaceous. So far most of the fossils attributed to Pellegrinisaurus are vertebra, however these are mostly from the tail with only a small number of back vertebrae known. This makes an exact size estimate impossible to establish because we … Read more

In Depth Fossils of Analong were originally assigned to the Chuanjiesaurus genus until they were granted their own distinct genus in 2020. Analong was a mamenchisaurid sauropod dinosaur that lived in China during the mid Jurassic. Further Reading A revision of the referred specimen of Chuanjiesaurus anaensis Fang et al., 2000: a new early branching … Read more
In Depth Brontomerus has been given its name for good reason, it had possibly the largest thigh muscles of all the known sauropods. This has been established from the proportionately large ilium that also projects forward. The ilium is where the thigh muscles attach and this enlargement not only suggests enlarged muscles but a degree … Read more
In Depth Pitekunsaurus was a titanosaurian dinosaur that lived in South America during the late Cretaceous. At the time of writing Pitekunsaurus is usually considered to be an aeolosaurine titanosaur, and as such a relative of such genera as Aeolosaurus, Panamericansaurus and Gondwanatitan. The type species name P. macayai is in honour of Luis Macaya … Read more
In Depth Phuwiangosaurus was first named as a titanosaurid dinosaur in 1994, and was the first named sauropod dinosaur known to have come from Thailand. The name Phuwiangosaurus translates as ‘Phu Wiang lizard’ and is a reference to the district of Phu Wiang District of Thailand. The species name P. sirindhornae was in honour of … Read more
