Variations in the Earth’s orbit and spin vector are a primary control on insolation and climate; their recognition in the geological record has revolutionized our understanding of palaeoclimate dynamics, and has catalysed improvements in the accuracy and precision of the geological timescale.

Mapping the age and trace element and Sm-Nd isotope compositions of monazite grains from a peraluminous Cretaceous granite using laser ablation–split stream analysis reveals a wide range in Nd isotope and rare earth element (REE) compositions within and between single grains. Show More Summary

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
Welcome to the Cretaceous Romanian island of Ha?eg, once populated by lifeforms stranger than anything imagined by Lovecraft or Geiger What makes ancient, extinct animals so compelling is that they are often beyond anything we can imagine. Show More Summary
Critics worry it would lead schools to ditch lessons about evolution and climate change in favor of teaching ideas like creationism.
It’s been said that the pterosaur, which can only be described as a bird-reptile-dinosaur-esque-thing, was the largest flying animal. This giant beast—which roamed the Earth during the Cretaceous period roughly 66.5 million years ago—was a reptile but not actually a dinosaur. Despite being winged, it wasn’t bird,… Read more...
CRETACEOUS UPDATE: Collagen reportedly extracted from 80 million year-old dinosaur fossil. Utilizing the most rigorous testing methods to date, researchers from North Carolina State University have isolated additional collagen peptides from an 80-million-year-old Brachylophosaurus.

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

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.
