Analysis of a finely preserved fossil dinosaur from China has revealed the animal’s erstwhile camouflage. It appears that the meter-high Early Cretaceous ceratopsid Psittacosaurus was light-colored on its underside and dark on top, a pattern known as countershading that may hint that the small herbivore lived in a dense forest environment. 11 Jan 2017
Footprints show that dinosaurs may have teamed up to hunt their prey

A Feathered Dinosaur Tail with Primitive Plumage Trapped in Mid-Cretaceous Amber Authors: Xi et al Abstract: In the two decades since the discovery of feathered dinosaurs, the range of plumage known from non-avialan theropods has expanded significantly, confirming several features predicted by developmentally informed models of feather evolution.

90 million years ago, the Canadian Arctic had more of a Floridian vibe.
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 […]
A new fossil discovery in North Dakota proves that possum-sized marsupials roamed North America during the Cretaceous age and had what may have been the most powerful mammalian jaws in history. How powerful? These marsupials actually ate dinosaurs much larger than them. Wait a minute … marsupials...
(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.
Scientists working in the Hukawng Valley in northern Myanmar have found something very special in a fragment of Cretaceous amber. The tail of a 99-million-year-old dinosaur, including bones, soft tissue, and even feathers, has been found...Show More Summary
A 99-million-year-old dinosaur tail complete with feathers has been found preserved in cretaceous amber, the first discovery of its kind. The remarkable tail was found in Kachin State, Myanmar by a team led by Dr. Lida Xing from China University of Geosciences, and through examination the team believes the tail belonged to a coelurosaur. A […]

A team of international scientists led by researchers from the Chinese Academy of Sciences reported recently the oldest fossil evidence of beta-keratin from feathers of a 130 million-year-old basal bird from the famous Early Cretaceous Jehol Biota.
Algae with siliceous structures are proposed to have originated following the Permian-Triassic extinction or even earlier, but there have been no robust fossil records to indicate their existence before the Jurassic–Cretaceous Periods. Show More Summary
Study Suggests Early Cretaceous Bird Had Flashy Feathers Fossils from the Jiufotang Formation of Liaoning Province (China), have provided scientists with an extensive data set that records life in the Early Cretaceous. The highly fossiliferous...Show More Summary
(Wiley) Scientists have recently discovered a new bohaiornithid bird specimen from the Early Cretaceous Period of China with remarkably preserved feathers. Bohaiornithid birds belonged to enantiornithes, a group of avian dinosaurs that lived millions of years ago.
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
This dinosaur’s bad luck turned out to be a boon for paleontologists.
Research Suggests Southern Hemisphere a Relatively Safe Haven after End Cretaceous Impact Event Life in much of the southern hemisphere seems to have recovered more quickly than ecosystems further north after the catastrophic Yucatan Peninsula impact event that marked the end of the Cretaceous. Furthermore, the southern parts of our planet may have provided a […]
The Cretaceous Oceanic Anoxic Event 1a (Early Aptian) is thought to be causally related to the eruption of the Ontong–Java Plateau large igneous province. This study uses osmium isotope records to quantify the magnitude of the respective CO2 emissions up to the onset of Ocean Anoxic Event 1a, and model the associated changes in carbonate […]
