In Depth A very small sauropod, Rayososaurus is considered to be very similar to another genus called Rebbachisaurus. Because Rayososaurus is from South America and Rebbachisaurus is from Africa, this has given rise to the notion that these two continents were joined for much longer than previously thought back in the Cretaceous.

In Depth Although not as famous as some sauropods like Apatosaurus and Diplodocus, Camarasaurus actually appears to have been the most common judging by the large numbers of remains. Some Camarasaurus specimens are actually almost complete and the genus also has one of the largest numbers of sauropod skulls attributed (for those who haven’t realised … Read more
In Depth Parvicursor is a genus of alvarezsaur known to have lived in Mongolia during the Late Cretaceous. Like with some relatives, Parvicursor had hands reduced to a single stubby horn which was likely used to punch holes into termite mounds so that an individual Parvicursor could feed upon the termites within.

In Depth Much of Segnosaurus is still unknown and as such reconstructions of Segnosaurus are usually based with the addition of Erlikosaurus material to fill in the missing parts. Although very similar to one another, Segnosaurus has a key difference in the mouth in that the outer surface of the lower jaw begins at the … Read more
In Depth Although only currently known from partial snout remains, it is still enough material to declare Oxalaia a spinosaurid due to the unique nature of the snout. Spinosaurid teeth were also known from the fossil site before the current material was discovered, and may have belonged to Oxalaia in life. With its total length … Read more
In Depth Although named from only partial remains, Karongasaurus is truly a dinosaur genus of the information age since its description was the first to be published solely online. The genus name Karongasaurus is in reference to the Karonga district of Malawi combined with the Ancient Greek for ‘lizard’. The species name is in honour … Read more
In Depth When the dinosaur Afromimus was first described in 2017 it was as an ornithomimosaur, however a later study in 2019 led to Afromimus being described as an abelisaur, specifically a noasaurid. Unfortunately Afromimus is still only known from partial remains, making details of this dinosaur difficult to know for certain. Further Reading - … Read more
In Depth Named after the Andes Mountains, Andesaurus was a titanosaurian sauropod dinosaur from South America, but one known from only incomplete remains. This makes it hard to be certain about such things as a total size or even a preferred diet beyond just general plants. The vertebrae of Andesaurus though suggest that the genus … Read more
In Depth As with other Australian sauropods such as Wintonotitan and Diamantinasaurus, the skull and most of the vertebrae are unknown. What can be learned from the available material is that Austrosaurus had a fairly level back between its shoulders and hips with what appears to be only twenty centimetres height difference between the two. … Read more
In Depth It is hard to currently establish a size estimate for Arcusaurus because at the time of writing the genus is only represented by the partial remains of two juveniles. Not only does this make it impossible to run a tape measure along a known complete specimen, but as juvenile they would have grown … Read more
