Archaeornithomimus

In Depth        In‭ ‬1972‭ ‬Dale Russel was undertaking a study of the ornithomimid dinosaurs which saw some of the focus fall upon Ornithomimus.‭ ‬After studying the fossils of this genus he discovered that while some of them were not attributable to Ornithomimus,‭ ‬but were of an unknown ornithomimid dinosaur.‭ ‬However while Russel correctly identified a … Read more

Anchiceratops

In Depth        Studies of fossil sites where Anchiceratops remains have been found have revealed that Anchiceratops lived around estuaries.‭ ‬This may explain why Anchiceratopsremains are rare when compared to the remains of other ceratopsians known to live on open plains.‭ ‬As a chasmosaurine ceratopsian,‭ ‬Anchiceratops had a large neck frill surrounded with bony triangular projections,‭ … Read more

Chinshakiangosaurus

In Depth        Despite being a little known genus of sauropod dinosaur,‭ ‬Chinshakiangosaurus is one of the most important.‭ ‬This is because when it was described,‭ ‬Chinshakiangosaurus was the only example of an early sauropod dinosaur where the sides of the head can be reconstructed.‭ ‬This has revealed that although Chinshakiangosaurus was a sauropod,‭ ‬the lower … Read more

Albertosuchus

In Depth        Albertosuchus is a genus of crocodile that lived in Canada during the late Cretaceous,‭ ‬and which is noted for being similar to‭ ‬Arenysuchus,‭ ‬which is known from similarly aged fossil bearing deposits in Spain.‭ ‬Albertosuchus should not be confused with Albertosaurus,‭ ‬a tyrannosaurid dinosaur of the late Cretaceous,‭ ‬though it is not impossible … Read more

Atolchelys

Miodentosaurus

In Depth        Exact measurements of Miodentosaurus have been hard to establish,‭ ‬but this could be the largest thalattosaur genus there is.‭ ‬At the time of writing the next largest genus is Concavispina,‭ ‬which is confirmed to have at least grown to as big as‭ ‬3.64‭ ‬meters long.‭ ‬Like its smaller cousins,‭ ‬Miodentosaurus was a reptile … Read more

Allopleuron

In Depth        Allopleuron was a large sea turtle that swam in the late‭ ‬Cretaceous seas and may have had a cosmopolitan distribution at least across the Northern Hemisphere.‭ ‬Several species have been named in the past but today some only consider the type species A.‭ ‬hofmanni as valid.‭ ‬With remains possibly being as late as … Read more

Aratasaurus

In Depth        Aratasaurus is a genus of Coelurosaurian theropod dinosaur that lived in South America during the early Cretaceous.‭ ‬The holotype individual of Aratasaurus is estimated to have been about four years old at the time of death,‭ ‬and only a juvenile or at most a sub adult.‭ ‬Older adults would have likely been larger,‭ … Read more

Ocepechelon

In Depth        Ocepechelon is a fascinating genus of sea turtle for two reasons.‭ ‬First,‭ ‬with a skull that was seventy centimetres long,‭ ‬Ocepechelon must have been huge,‭ ‬but unfortunately without a shell and/or post cranial skeleton we don’t know how big.‭ ‬Second,‭ ‬the mouth of Ocepechelon is formed into a pipette-like feature which suggests that … Read more

Adynomosaurus

In Depth        Adynomosaurus is a genus of lambeosaurine hadrosaurid dinosaur that lived in Spain during the late Cretaceous. Further Reading -‭ ‬Adynomosaurus arcanus,‭ ‬a new lambeosaurine dinosaur from the Late Cretaceous Ibero-Armorican Island of the European Archipelago.‭ ‬-‭ ‬Cretaceous Research.‭ ‬96:‭ ‬19‭–‬37.‭ ‬-‭ ‬Albert Prieto-M�rquez,‭ ‬Victor,‭ ‬Fondevilla,‭ ‬Albert G.‭ ‬Sell�s,‭ ‬Jonathan R.Wagner‭ & ‬�ngel Galobart‭ … Read more
