Anserimimus

In Depth        With an estimated length of around three meters long Anserimimus was towards the smaller end of the scale in terms of ornithomimosaur size.‭ ‬Other related dinosaurs from the same area such as Gallimius would have been at least double this size,‭ ‬while the very incomplete Deinocheirus would have been even larger than this.‭ … Read more

Adeopapposaurus

In Depth        Initially considered to be a Southern population of Massospondylus,‭ ‬Adeopapposaurus was established as an independent genus in‭ ‬2009.‭ ‬Adeopapposaurus is an unusual sauropodomorph since it appears to have had a keratinous beak to its mouth.‭ ‬If correct,‭ ‬then this may have been a feeding specialisation for snipping off foliage from plants.

Faxinalipterus

In Depth        Faxinalipterus is a contender for the oldest known pterosaur, although some have put forward the notion that it may be a form of reptile just before true pterosaurs.

Andrianavoay

In Depth        Originally named as a species of Steneosaurus,‭ ‬S.‭ ‬baroni was found to represent a distinct genus in a university thesis written by Michela M.‭ ‬Johnson in‭ ‬2019.‭ ‬The following year a new genus description was published for S.‭ ‬baroni,‭ ‬and thus the Andrianavoay genus was established.‭ ‬Andrianavoay was a thalattosuchian,‭ ‬but a more … Read more

Stratesaurus

In Depth        Stratesaurus represents a genus of rhomaleosaurid plesiosaur,‭ ‬a type of plesiosaur noted for having a shorter neck and proportionately larger head than other plesiosaurs,‭ ‬though not to the extent of pliosaurs.‭ ‬The discovery of Stratesaurus in Hettangian aged rocks means that individual Stratesaurus were swimming in European waters near the Triassic/Jurassic boundary,‭ ‬which … Read more

Omeisaurus

In Depth        With its incredibly long neck Omeisaurus is both a relative and possible comtempory to the more famous Mamenchisaurus.‭ ‬However previous Upper Shaximiao Formation fossils of Omeisaurus are now considered indeterminate.‭ ‬If Omeisaurus really‭ ‬does‭ ‬only exist in Lower Shaximiao deposits,‭ ‬then it may confirm that Mamenchisaurus replaced Omeisaurus since the former is only … Read more
