In Depth Although known from only a single partial skull, Nemegtosaurus is quite a find as titanosaurid dinosaurs are often only known from post cranial remains. However another titanosaurid called Opisthocoelicaudia is also known from the same Formation as Nemegtosaurus, and this one is only known from post cranial remains. This has led some to … Read more
In Depth Mansourasaurus is a genus of titanosaurian sauropod dinosaur that lived in North Africa during the late Cretaceous. The discovery of Mansourasaurus was significant in itself because North African fossil beds often do not yield remains of larger dinosaurs like sauropods. This is partly because the harsh arid conditions of North Africa will often … Read more
In Depth The lightly built skull of Abrosaurus (which is the inspiration for the name ‘delicate lizard’) clearly indicates that it was a macronarian sauropod, similar to genera such as Brachiosaurus and Camarasaurus. Camarasaurus in particular has been considered to be a very close relative of Abrosaurus because they both seem to represent basal (primitive) … Read more
In Depth The first Masiakasurus remains were described in 2001, and a second set of remains were recovered in 2011. This has allowed some of the original gaps including the premaxilla to be included with the overall morphology. The most striking feature of Masiakasaurus is the way the front teeth point forward and out of … Read more
In Depth Protarchaeopteryx was so named because of a superficial similarity to the genus Archaeopteryx. However today, Protarchaeopteryx is seen as a very primitive member of the Oviraptosauria, and one that bears a strong resemblance to the genus Incisivosaurus. Protarchaeopteryx was a small dinosaur, and one that probably specialised in hunting small animals like lizards … Read more
In Depth Triunfosaurus is a genus of sauropod dinosaur that lived in South America during the early Cretaceous. Described only from an ischium and tail vertebra, Triunfosaurus was originally described as a titanosaur.

In Depth A little known theropod dinosaur from China, a 2010 study by Benson et al found Chuandongocoelurus to probably be related to the more complete Monolophosaurus. The partial remains of Chuandongocoelurus are thought to be from a juvenile/subadult individual, and coupled with the overall incomplete nature of them, it is impossible to establish an … Read more

In Depth As of the time of writing dinosaur genera are not particularly well known from Thailand, even though there does seem to be substantial fossil deposits in certain areas of the country. From here we have the discovery of Kinnareemimus, significant in that it may be one of and possibly the oldest ornithomimosaur discovered. … Read more
In Depth Notatesseraeraptor is a genus of theropod dinosaur that lived in Europe during the late Triassic. Notatesseraeraptor has had several parts described in three Master’s thesis, but was not formally named as a distinct genus until 2019.
