In Depth Known from the late Cretaceous period of Europe, Betasuchus was originally known as a species of Megalosaurus, the first genus of dinosaur, and theropod to be named which saw it being treated as a ‘wastebasket’ for all future theropod remains until more in depth study into dinosaurs began to be conducted. This classification … Read more
In Depth Although Demandasaurus is not represented by a lot of complete fossil material, it has been identified as a rebbachisaurid sauropod. As a rebbachisaurid, Demandasaurus was a form of diplodocid sauropod, and an offshoot of the Dicraeosaurinae. Demandasaurus would have course been related to the type genus of the Rebbachisauridae, Rebbachisaurus, but it has … Read more
In Depth Knightia were small freshwater fish often described as ‘herring-like’ that lived in North America during the Eocene period. Also because Knightia were schooling fish they are often preserved still in their shoals with some specimens even being preserved on top of each other. This is why so many fossils of this fish are … Read more
In Depth The beak of Genyornis was sharp and powerful, but unfortunately it is difficult to say what its diet was as it would have been useful for either a carnivore or herbivore. It is also equally possible that Genyornis was an omnivore, feeding from plants but also supplementing its diet by scavenging carrion. This … Read more
Due to the fragmentary nature of the known fossil, not much can be said about Vampyrictis other than it appears to have been one of the last of the African barbourofelids.
In Depth Though only known from the forward half of a skull, Raranimus was still a very exciting discovery, as not only is Raranimus one of it not the oldest therapsids known, it appears to be a transitional form that links therapsids with earlier sphenacodont pelycosaurs (i.e. Sphenacodon, Dimetrodon, Secodontosaurus, etc). At the time of … Read more
In Depth Paradoxically Micropachycephalosaurus is one of the smallest dinosaurs that we know about, yet it easily has one of the longest names. Micropachycephalosaurus was named from a partially preserved individual that in 1978 was perceived as what we now call a pachycephalosaur. However more modern analysis in the early portion of the twenty-first century … Read more

Further reading - Yakemys multiporcata n. g. n. sp., a Large Macrobaenid Turtle from the Basal Cretaceous of Thailand, with a Review of the Turtle Fauna from the Phu Kradung Formation and Its Stratigraphical Implications. … Read more
In Depth Gorynychus is a genus of therocephalian therapsid that lived in Russia during the Permian. At the time of writing Gorynychus is known from two species, the type (first to be named) species G. masyutinae, and the second species, G. sundyrensis, which seems to have been slightly larger. Further Reading - A new therocephalian … Read more
In Depth The holotype remains of Volkheimeria were found in close proximity to the remains of five individuals of the sauropod Patagosaurus as well as two individuals of the theropod Piatnitzkysaurus. Volkheimeria has a substantially shorter ilium than Patagosaurus, so even though the remains of Volkheimeria are vastly incomplete, it seems to have been a … Read more
