AUSTIN, Texas — A trove of exceptionally preserved Jurassic marine fossils discovered in Canada, rare for recording soft-bodied species that normally don’t fossilize, is expanding scientists’ view of the rich marine life of the period. (more…)

There’s a twist in the turtle timeline.
Thanks to new fossil evidence, paleontologists are able to prove that turtles share a recent common ancestor with birds and crocodiles. The discovery may settle a longstanding argument among scientists about the origins of turtles. (more…)
UChicago collaboration unveils African dinosaur Spinosaurus, 9 feet longer than T. rex
Scientists have unveiled what appears to be the first truly semiaquatic dinosaur, Spinosaurus aegyptiacus. New fossils of the massive Cretaceous-era predator reveal it adapted to life in the water some 95 million years ago, providing the most compelling evidence to date of a dinosaur able to live and hunt in an aquatic environment.

As big data access shifts to the masses, The Weather Company and other top global companies are showing the world how it’s done.
REDMOND, Wash. — Feb. 12, 2012 —Big data is changing the way organizations do business, make discoveries, and interact with each other. In fact, pundits are predicting that 2013 will be the year organizations across a range of industries begin implementing big data strategies, or face obsolescence. As David Selinger wrote in a recent article on Forbes online: “If executives don’t find a way to trap, tame, and train their data monsters, they’ll be extinct in two years—fossils who’ve missed the new world order.”
Microsoft believes that big data has the power to drive practical and theoretical insights that have eluded people to date. In the past, high costs and technology limitations have constrained access to data storage infrastructure and the tools needed to manage and analyze large quantities of data. This is finally starting to change. (more…)
The asteroid collision widely thought to have killed the dinosaurs also led to extreme devastation among snake and lizard species, according to new research — including the extinction of a newly identified lizard Yale and Harvard scientists have named Obamadon gracilis.
“The asteroid event is typically thought of as affecting the dinosaurs primarily,” said Nicholas R. Longrich, a postdoctoral associate with Yale’s Department of Geology and Geophysics and lead author of the study. “But it basically cut this broad swath across the entire ecosystem, taking out everything. Snakes and lizards were hit extremely hard.” (more…)
Although humans and woolly mammoths co-existed for millennia, the shaggy giants disappeared from the globe between 4,000 and 10,000 years ago, and scientists couldn’t explain until recently exactly how the Flintstonian behemoths went extinct.
In a paper published June 12 in the journal Nature Communications, UCLA researchers and colleagues reveal that not long after the last ice age, the last woolly mammoths succumbed to a lethal combination of climate warming, encroaching humans and habitat change — the same threats facing many species today.

How do we understand what’s happening today by looking back millions of years?
Scientists are looking at what climate conditions were like 3.3 to 3 million years ago, during a geologic period known as the Pliocene, and they are confident in the accuracy of their data.
The Pliocene is the most recent period of sustained global warmth similar to what is projected for the 21st century. Climate during this time period offers one of the closest analogs to estimate future climate conditions. (more…)
GAINESVILLE, Fla. — Did an ancient crocodile relative give the world’s largest snake a run for its money?
In a new study appearing Sept. 15 in the journal Palaeontology, University of Florida researchers describe a new 20-foot extinct species discovered in the same Colombian coal mine with Titanoboa, the world’s largest snake. The findings help scientists better understand the diversity of animals that occupied the oldest known rainforest ecosystem, which had higher temperatures than today, and could be useful for understanding the impacts of a warmer climate in the future.
