Ankylosaurus magniventris - Not Your Archetypal Ankylosaur A newly-published study has provided fresh insights on Ankylosaurus. This Ornithischian dinosaur, a contemporary of Tyrannosaurus rex in the Late Cretaceous of North America, is perhaps, one of the best-known of all the armoured dinosaurs in the minds of the public, however, this dinosaur star of stage and screen with
Augustynolophus Makes the Grade The duck-billed dinosaur Augustynolophus morrisi has become the state dinosaur symbol for California. "Auggie" as this Late Cretaceous member of the Hadrosaurinae has been nick-named by campaigners, joins a long list of symbols for the "Golden State". Thus, California becomes the eighth state in the Union to adopt a dinosaur as an
Late Cretaceous Tyrannosaurs Feature in Dinosaur Diorama Our thanks to Robert Townsend who set us some more photographs of the prehistoric animal inhabitants of his large dinosaur inspired diorama. This time, the theme is Late Cretaceous Tyrannosaurus and the enthusiastic model maker has created a number of mini scenes featuring "Tyrant Lizard Kings" and their
Giant Prehistoric Frog Capable of Tackling Small Dinosaurs Ever since it was formally named and described back in 2008, the beach-ball-sized Late Cretaceous frog Beelzebufo (B. ampinga) has fascinated scientists. The fossil record of frogs (Order Anura), is very poor, although these small, usually unobtrusive creatures have a long evolutionary history. Imagine the surprise of
Deltasuchus motherali - Unlocking the Fauna of Appalachia A team of researchers based in the United States have uncovered the remains of an early Late Cretaceous crocodile that is distantly related to modern-day crocodiles. The discovery comes from the Arlington Archosaur Site, this location is rapidly proving to be one of the best sites
Large Theropod Tooth Indicates Tyrannosaurs Roamed Japan Researchers have identified a single, shed Theropod tooth that indicates that large Tyrannosaurs roamed the land that we now know as Japan some 80 million years ago. The single tooth is very characteristic of a member of the Tyrannosauridae family, however, it is not possible to identify a
Rebor "Crimson King" Carnotaurus Model Reviewed Rebor's latest addition to their 1:35 scale model range is the "Crimson King", a replica of Carnotaurus (C. sastrei), a large carnivorous dinosaur from the Late Cretaceous of Argentina. The model has an articulated lower jaw and is supplied with its own base, a representation of a lava field.
Owl Creek Ceratopsid Tooth and Palaeoenvironment Implications Yesterday, team members at Everything Dinosaur published an article on the discovery of a single fossil tooth from a Late Cretaceous horned dinosaur that had been found in Union County (Mississippi). This discovery, the first evidence of a dinosaur from the Owl Creek Formation, has implications for the
The fossilized remains of a Late Cretaceous dinosaur embryo that famously graced the cover of National Geographic in the 1990s have been identified as a new species of oversized oviraptorosaur. Weighing nearly 2,500 pounds as adults, these dinos were the largest roosting animals to ever appear on Earth—tending to… Read more...
Chenanisaurus barbaricus - Substantial Abelisaurid from Late Cretaceous Morocco One of the last types of dinosaur to have existed in north Africa has been described in a new scientific paper published in the journal "Cretaceous Research". A fragment of jaw bone (dentary) and isolated teeth discovered in a phosphate mine at Sidi Chennane in the Oulad
Late Cretaceous Hadrosaur "Japan's Greatest Dinosaur Fossil Find" Scientists for Hokkaido University and Hobetsu Museum have announced the discovery of the fossilised remains of a Late Cretaceous duck-billed dinosaur. In truth, a number of fragmentary fossils relating to a dinosaur had been found some years earlier, most notably caudal vertebrae (tail bones), before a more
An ancient nest hidden since the late Cretaceous period.
This morning, I joined my wife, daughter and grandson for a hike at Roxborough State Park, southwest of Metro Denver. Adorned with spectacular rock formations from the Cretaceous, Permian and Pennsylvanian Periods, it is one of the most scenic preserves in Colorado.Though rain was threatening, we completed a two mile loop through the Park.

The bodiless plesiosaur In 2011, a plesiosaur specimen, consisting of an isolated and crushed skull, was described. The collected skull sadly lacked any postcranial remains, but was identified as an elasmosaurid plesiosaur and considered to […]
About 66 million years ago, a dinosaur lay down on a muddy riverbank in what is now Spain, leaving behind the impression of its scaly skin. A team studying sandstone formations near the village of Vallcebre in the Pyrenees recently uncovered...Show More Summary
Didelphodon Study Suggests a Powerful Bite Research published in the academic journal “Nature Communications” suggests that dinosaurs in the Late Cretaceous, did not have it all their own way when it came strong teeth and powerful jaws. This new study, conducted by scientists from the Burke Museum and the University of Washington, indicates that the […]
(Cleveland Museum of Natural History) Scientists identify two new tribes of ceratopsian dinosaurs based on distinctions in frill ornamentation. These two tribes employed different strategies and lived side-by-side in the Late Cretaceous in what is now western North America.
Largest Mosasaur from Antarctica Described – Kaikaifilu hervei A team of international researchers writing in the journal “Cretaceous Research”, have published details of the largest Mosasaur to be identified from Upper Cretaceous strata in Antarctica. Show More Summary
The Western Interior Seaway (WIS) was a shallow and expansive body of water that covered the central United States during the Late Cretaceous. Attempts to reconstruct temperatures in the seaway using the oxygen isotopic composition of...Show More Summary
Proxy temperature reconstructions indicate a dramatic cooling from the Cenomanian to Maastrichtian. However, the spatial extent of and mechanisms responsible for this cooling remain uncertain, given simultaneous climatic influences of tectonic and greenhouse gas changes through the Late Cretaceous.
