The environmental benefits of taller, shrubbier tundra plants in the Arctic may be overstated, according to new research involving the University of Stirling.
Using X-ray-based technology developed at Brown University, researchers uncover shared subsurface movement patterns between birds and dinosaurs, adding a new dimension of fossil track diversity.
New Zealand's monster penguins that lived 62 million years ago had doppelgangers in Japan, the USA and Canada, a study published today in the Journal of Zoological Systematics and Evolutionary Research has found.
Modelling of the Chicxulub asteroid impact 66 million years ago shows it created a world largely unsuitable for dinosaurs to live in.
A giant marsupial that roamed prehistoric Australia 25 million years ago is so different from its wombat cousins that scientists have had to create a new family to accommodate it.
The history of our planet has been written, among other things, in the periodic reversal of its magnetic poles. Scientists at the Weizmann Institute of Science propose a new means of reading this historic record: in ice. Their findings could lead to a refined probing ice cores and, in the future, might be applied to understanding the magnetic history of other bodies in our solar system, including Mars and Jupiter's moon Europa.
It's not often that scientists are able to find tuff in continental sedimentation, but this was accomplished in the PreUrals region by Kazan Federal University, Borisyak Institute of Paleontology, and Institute of Geology (the latter two are parts of the Russian Academy of Sciences). This was a first such finding on the territory of European Russia. Radioisotopic analysis was conducted by Boise State University.
The sweeping pink salt lakes across Australia's interior are all that remain of the lush green places three species of pink flamingos once thrived the outback. Some much larger than flamingos now found in Africa and other parts of the world, Australian flamingos enjoyed a range of freshwater habitats for about 25 million years, Flinders University researchers say.
A research team led by the University of Tsukuba excavated over 1300 eggshell fossils from the Lower Cretaceous Ohyamashimo Formation of Hyogo Prefecture, Japan. Over 96% of these fossils, including numerous fragments, four partial and almost complete eggs in an in situ nest, belonged to a new ootaxon the authors named Himeoolithus murakamii, attributed to a small non-avian theropod dinosaur. The remaining eggshell fragments, belonging to five additional small theropod ootaxa, showed notable biodiversity.
An international collaboration between researchers at Harvard University and Yunnan University in China uses microCT to study and restudy arthropod fossils from the early Cambrian in the Chengjiang biota in the Yunnan Province of China. Their latest study shows with unprecedented clarity the head morphology of the species Leanchoilia illecebrosa and demonstrates the presence of a labrum thus supporting the hypothesis that megacheirans are distant relatives of modern chelicerates (e.g. horshoe craps, scorpions and spiders).
