The more we learn about dinosaurs, the less they seem like the scaly lizards of Jurassic Park. Take the Therizinosaurs: their feathers and powerful hind legs made them rather bird-like, while their long, trailing arms and curved claws were more reminiscent of sloths.

The recent discovery of a huge trove of fossilised eggs thought to be laid by a Therizinosaur complicates this picture further. The evidence suggest these dinosaurs buried their eggs and protected their nests, much like certain species of megapode birds and members of the crocodile family do today.

The researchers behind the find came to this conclusion by comparing the fossilised eggs to those of modern megapodes. But our author Jason Gilchrist, a behavioural ecologist who studies how animals live their lives, thinks we can take the comparison further. He argues these dinosaurs may have worked as a community to protect each other’s nests but that, once they hatched, the young dinosaurs would have been left to fend for themselves.

That’s not the only feathery discovery we’ve learnt about this week as an extinct species of giant parrot almost one metre tall has been discovered in New Zealand – and nicknamed Hercules. We’re also mourning the death of American literary giant Toni Morrison, and wondering why bubbles come in so many sizes.
