Badger-sized Didelphodon Had a Bite More Powerful than a Hyena

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 […]

Fossils Show North America Was the Birthplace of Marsupials

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...

Scientists redefine horned dinosaur relationships by naming 2 new ceratopsian tribes

(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.

Scientist find dinosaur tail preserved in amber—and it's covered in feathers

Beta-keratin discovery in bird feather fossil may help identify paleo colo

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.

Triassic chrysophyte cyst fossils discovered in the Ordos Basin, China

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

Researchers uncover details behind dinosaur-era birds' feathers

(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.

Rapid Recovery of Patagonian Plant-Insect Associations

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 […]

Quantifying the volcanic emissions which triggered Oceanic Anoxic Event 1a and their effect on ocean acidification

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 […]
