It’s certainly valuable new information. The outstanding puzzle has always been, why were all dinosaurs killed off but not all mammals or reptiles?
Actually, the Anthropocene is mainly a testament to the enormous power of immaterial ideas to shape things, for good or ill. It is the best argument against materialism and it is right under our noses.
But the Woke war on science, now that IS real.
Some think the remarkable spines were for protection, others only for display.
Sixty-six million years ago, an asteroid hit the Yucatan Peninsula in Mexico and produced cataclysmic disruptions that, it is believed, killed off about 75% of species (the K/Pg extinction). But many researchers think there must have been other factors at work.
We are starting to get so much more information now: Andrew had a short narrow snout, whereas his parents had wide, square snouts. His snout was suited to forests, but his parents would be grazing the ground in open areas. But if adults fed their babies, why would they need to have different teeth and snouts? […]
Turns out we didn’t need Jurassic Park: The lungs and feathers of a bird that lived 120 million years ago had some of the same characteristics found in today’s birds, researchers reported yesterday (October 18) in PNAS… They examined a sample with scanning electron microscopy and found an extremely subdivided structure much like that enabling […]
Paleontologist Gerta Keller attributes the extinction 66 million years ago of three-quarters of Earth’s species, including all dinosaurs, not to an asteroid hit but to a series of volcanic eruptions. A writer goes with her on a field trip: The prestige of science is solidly behind the asteroid: The impact theory provided an elegant solution […]
For one thing, advanced dinosaurs existed much earlier than thought. From ScienceDaily: “We were surprised to find a close relative of Diplodocus in East Asia 174 million years ago. It’s commonly thought that sauropods did not disperse there until 200 million years ago and many of their giant descendants, reached this region much later, if […]
Sometimes. From Helen Gordon at Wired: Long thought an impossible dream, the emerging field of palaeocolour is revolutionising our view of the prehistoric world, turning it from black-and-white into glorious technicolour. So far only a handful of dinosaurs, insects and reptiles have been studied but, as Johan Lindgren, a scientist from the University of Lund, […]
