We ’re finding out more about dinosaurs than ever – but their sex lives still elude us | Dave Hone
With each new find, such as the dinosaur leg recently unearthed in North Dakota, scientists build a more colourful picture of the ancient reptilesAlthough they became extinct 66m years ago, dinosaurs are always news. The latest manifestation of that is the media shower generated bythe discovery of the perfectly preserved leg, including remnants of skin, of a dinosaur in North Dakota.It is suggested that this dinosaur, discovered at the Tanis fossil site, died on the very day the asteroid that caused the mass extinction of all the dinosaurs struck the Earth. It sounds almost too good to be true, but should make for a fascin...

Scientists find fossil of dinosaur ‘killed on day of asteroid strike’
Remains of thescelosaurus in North Dakota believed to date back to extinction of species 66m years agoScientists believe they have been given an extraordinary view of the last day of the dinosaurs after they discovered the fossil of an animal they believe died that day.The perfectly preserved leg, which even includes remnants of the animal ’s skin, can be accurately dated to the time the asteroid that brought about the dinosaurs’ extinction struck Earth 66m years ago, experts say, because of the presence of debris from the impact, which rained down only in its immediate aftermath.Continue reading...

The zoologist sticking her neck out in the battle of the sexes
Our ideas about males and females are wildly out of date, says zoologist Lucy Cooke. Here, she reveals some radical truths about the birds, the bees … and the bonobosLondon Zoo at half-term is a cheerful cacophony with blue macaws out-screaming six-year-olds, but in the relative calm of the lush spider “walkthrough” exhibit (apologies, arachnophobes), Lucy Cooke is happily absorbed. “Let’s see if we can see a big predatory female,” she says. We can: a gorgeously colourful golden orb weaver sits in the centre of her vast gold-tinted web, 125 times bigger than her tiny mate. “I didn’t realise that the majorit...

Paleontology ‘a hotbed of unethical practices rooted in colonialism’, say scientists
The study of fossils and prehistoric species is exploitative of local communities, says international teamThe public image of palaeontologists as dusty, but rather affable academics, could be due an update. The study of ancient life is a hotbed of unethical and inequitable scientific practices rooted in colonialism, which strip poorer countries of their fossil heritage, and devalue the contributions of local researchers, scientists say.Writing in the journalRoyal Society Open Science, an international team of palaeontologists argue that there has been a steady drain of plesiosaurs, pterosaurs, prehistoric spiders, and othe...

Tyrannosaurus rex may have been three species, scientists say
Experts say there is enough variation in samples to argue there was also a Tyrannosaurus imperator and a reginaWith its immense size, dagger-like teeth and sharp claws, Tyrannosaurus rex was a fearsome predator that once terrorised North America. Now researchers studying its fossils have suggested the beast may not have been the only tyrannosaurus species.Experts studying remains thought to belong to T rex have suggested their variation shows evidence of not one species but three.Continue reading...
