Albertonectes

In Depth        Albertonectes is one of the best preserved elasmosaurid plesiosaurs to be discovered in Canada,‭ ‬and has a total of‭ ‬76‭ ‬cervical‭ (‬neck‭) ‬vertebrae‭ ‬.‭ ‬Elasmosaurid pesiosaurs like Albertonectes are noted for having their long necks that are proportionately much longer than earlier plesiosaur types.‭ ‬This would have been a specialist feeding adaptation allowing … Read more

Alexandronectes

In Depth        Described from a single partially preserved skull,‭ ‬Alexandronectes was an elasmosaurid plesiosaur that swam in the waters around what is now New Zealand during the late Cretaceous.‭ ‬These were dangerous waters as fossils of large mosasaurs such as Taniwhasaurus are also known from the same formation as Alexandronectes,‭ ‬and these predators were certainly … Read more

Ultrasaurus

In Depth        Due to the incomplete nature of the holotype fossils,‭ ‬Ultrasaurus is today seen as a dubious genus of sauropod dinosaur,‭ ‬given that it would be near impossible to attribute further remains to the genus.‭ ‬Ultrasaurus is actually more‭ ‬famous for forcing a naming change in a North American genus of diplodocid dinosaur.‭ ‬In‭ … Read more

Hungarosaurus

In Depth        Several hundred bones from an estimated four individuals have been attributed to this genus,‭ ‬and together they make up the best represented European genus of nodosaurid dinosaur.‭ ‬Like its nodosaurid relatives,‭ ‬Hungarosaurus was an armoured quadrupedal dinosaur that would have browsed upon low growing vegetation.‭ ‬The armour would have been an arrangement of … Read more

Lessemsaurus

In Depth        Lessemsaurus is a genus of sauropod dinosaur named in honour of the Don Lessem,‭ ‬an author noted for his work writing popular science books.‭ ‬Although Lessemsaurus is so far only based upon the description of vertebrae.‭ ‬These vertebrae are noted for having tall neural spines,‭ ‬something which may hint at a fleshy or … Read more

Adamantisaurus

In Depth        Remains of Brazilian dinosaurs are often noted as being incomplete‭ (‬for example,‭ ‬the increasingly famous spinosaurid Oxalaia was named from only the tip of the snout‭)‬,‭ ‬and Adamantisaurus was no exception to this since it was named from only six caudal vertebrae.‭ ‬These six vertebrae were originally written about in‭ ‬1959‭ ‬by Sergio … Read more

Rhinorex

In Depth        Rhinorex is a genus of saurolophine hadrosaur that lived in the USA during the late Cretaceous.‭ ‬Rhinorex can be further identified as a‭ ‬kritosaurine due to the development of the bones on the snout which would have formed a bony display structure in life.‭ ‬However,‭ ‬Rhinorex is also noted as being very similar … Read more

Agustinia

In Depth        Like with many sauropod dinosaurs,‭ ‬Agustinia‭ ‬is known from incomplete remains.‭ ‬Some of these remains however revealed a startling revelation in that this sauropod had what appeared to be armour along its back similar in appearance to the plates of Stegosaurus,‭ ‬a herbivorous but completely different kind of dinosaur.‭ ‬This is in particular … Read more
