Jaxartosaurus

In Depth        Although not very well known,‭ ‬Jaxartosaurus possesses a hollow helmet shaped crest on top of its skull similar to the better known Corythosaurus.‭ ‬Because this crest is hollow,‭ ‬Jaxartosaurus had been confidently assigned to the Lambeosaurinae group of hadrosaurs which are typified by their hollow crests.‭ ‬The crest of Jaxartosaurus like its lambeosaurine … Read more

Ulemosaurus

In Depth        Ulemosaurus is very much like the therapsid Moschops,‭ ‬not only in the type of creature that it was,‭ ‬but also in the fact that its skull was also up to ten centimetres thick.‭ ‬Its possible that like in the related Moschops,‭ ‬this bone thickness allowed for head butting or head pushing contests.        Although … Read more

Rukwatitan

In Depth        Fossils of this titanosaur were found near lake Rukwa in the Rukwa Valley of Tanzania,‭ ‬so the eventual name of Rukwatitan was really just a foregone conclusion.‭ ‬At about nine meters long,‭ ‬the holotype appears to indicate that Rukwatitan was a fairly small genus of titanosaur.‭ ‬One area of note is that the … Read more

Livyatan

livyatan

In Depth        When first described the prehistoric whale Livyatan was actually named Leviathan after the biblical sea monster.‭ ‬Unfortunately however Leviathan had already been used to name a mastodon now known as Mammut‭ (‬Leviathan is actually a synonym to this genus,‭ ‬but still cannot be used‭)‬.‭ ‬As such the Hebrew word for Leviathan,‭ ‬Livyatan,‭ ‬is … Read more

Laosaurus

In Depth        Laosaurus is today considered to be a dubious genus of dinosaur.‭ ‬Though previously considered to be a hypsilophodont‭ (‬relative of Hypsilophodon‭)‬,‭ ‬most of the fossil remains once attributed to Laosaurus have ended up being considered to be other genera such as Orodromeus,‭ ‬Dryosaurus and Othnielosaurus.‭ ‬What few fossils that are still assigned to … Read more

Tataouinea

In Depth        Although only known from partial remains,‭ ‬Tataouinea has been identified as a rebbachisaurid sauropod,‭ ‬and one that is closely related to genera such as Nigersaurus,‭ ‬which are also known to have been present in North Africa during the early Cretaceous.‭ ‬The fossils of Tataouinea have revealed in life the bones of Tataouinea would … Read more

Paramachairodus

In Depth        Paramachairodus is a genus of sabre-toothed cat that lived during the Miocene/Pliocene.‭ ‬The Paramachairodus genus represents one of the first true sabre-toothed cats to appear. Further Reading -‭ ‬Aspects of the functional morphology in the cranial and cervical skeleton of the sabre-toothed cat Paramachairodus ogygia‭ (‬Kaup,‭ ‬1832‭) (‬Felidae,‭ ‬Machairodontinae‭) ‬from the Late Miocene … Read more

Majungasaurus

majungasaurus

In Depth        When first discovered only the top part of the skull of Majungasaurus was known.‭ ‬This fragment revealed a dome like structure which was taken to be indicative of a pachycephalosaur.‭ ‬Further fossil material would reveal the truth about Majungasaurus being a carnivorous theropod,‭ ‬although this was not the first time that a carnivorous … Read more

Hadrocodium

In Depth        The tiny holotype fossil of Hadrocodium has been considered to represent a very primitive ancestor of modern mammals,‭ ‬though it is not a mammal in itself.‭ ‬This means that there are many unanswered questions about this little creature,‭ ‬specifically concerning the biology of the metabolism and exactly how much like a true mammal … Read more
