Canadian tundra formerly covered in rich forest: Ancient plant fossil record shows
SASKATOON–The heady aroma of magnolia blossoms and lotus flowers might have wafted to your nostrils if you had gone for a walk 56 million years ago in the lush green forest which covered Canada’s northernmost islands. Now covered in ice…
Paleontology: Experiments in evolution
A new find from Patagonia sheds light on the evolution of large predatory dinosaurs. Features of the 8-m long specimen from the Middle Jurassic suggest that it records a phase of rapid diversification and evolutionary experimentation. In life, it must…
Earth was stressed before dinosaur extinction
Fossilized seashells show signs of global warming, ocean acidification leading up to asteroid impact
A new early whale, Aegicetus gehennae, and the evolution of modern whale locomotion

New early Cretaceous mammal fossils bridge a transitional gap in ear’s evolution
Fossils of a previously unknown species of Early Cretaceous mammal have caught in the act the final steps by which mammals’ multi-boned middle ears evolved, according to a new study. The new species the study unearths – based on fossil…
Dull teeth, long skulls, specialized bites evolved in unrelated plant-eating dinosaurs
Herbivorous dinosaurs evolved many times during the 180 million-year Mesozoic era, and while they didn’t all evolve to chew, swallow, and digest their food in the same way, a few specific strategies appeared time and time again. An investigation of…

The impact of the soil microbiota on the mitigation of greenhouse gases in tropical forests
Besides that, two other initiatives that look at the challenges of climate change related to geological sediments and emissions resulting from sugarcane production were presented at FAPESP Week France.
Four USC professors named AAAS fellows
Four USC professors have been selected as fellows of the American Association for Advancement of Science (AAAS), a top honor bestowed to leading scientists for research excellence and service to education. The new USC fellows are: Stephen Bradforth, professor of…

Unique sledge dogs helped the Inuit thrive in the North American Arctic
A unique group of dogs helped the Inuit conquer the tough terrain of the North American Arctic, major new analysis of the remains of hundreds of animals shows. The study shows that the Inuit brought specialised dogs with them when…
16-million-year-old fossil shows springtails hitchhiking on winged termite
When trying to better the odds for survival, a major dilemma that many animals face is dispersal — being able to pick up and leave to occupy new lands, find fresh resources and mates, and avoid intraspecies competition in times…
Dinosaur skull turns paleontology assumptions on their head
University of Alberta paleontologists uncover spiky skull–and overturn long-standing assumptions in identifying horned dinosaurs.

An ancient snake’s cheekbone sheds light on evolution of modern snake skulls
100-million-year old legged snake fossil provides critical insight into how the heads of modern snakes evolved
Only eat oysters in months with an ‘r’? Rule of thumb is at least 4,000 years old
GAINESVILLE, Fla. — Foodie tradition dictates only eating wild oysters in months with the letter “r” – from September to April – to avoid watery shellfish, or worse, a nasty bout of food poisoning. Now, a new study suggests people…
New fossils shed light on how snakes got their bite and lost their legs
New fossils of an ancient legged snake, called Najash, shed light on the origin of the slithering reptiles.
Lichens are way younger than scientists thought
You’ve probably seen a lichen, even if you didn’t realize it. If you’ve ever meandered through the forest and wondered what the crusty stuff on trees or rocks was, they’re lichens, a combination of algae and fungi living together almost…

Extinct giant ape directly linked to the living orangutan
Researchers have succeeded in reconstructing the evolutionary relationship between a 2-million-year-old giant primate and the living orangutan; it is the first time genetic material this old has been retrieved from a fossil in a subtropical area

Superfood for Mesozoic herbivores? Emerging data on extreme digestibility of equisetum and implications for young, growing herbivorous sauropods
The long-necked, big bodied sauropod dinosaurs comprise some of the largest terrestrial vertebrates to walk the earth. These behemoths were herbivores that survived solely on plant material. There has been long speculation as to what food resources could have supported…
