The cover shows an artist’s impression of the pterosaur Tupandactylus imperator. Although feathered pterosaurs have been reported, these claims have been controversial and it has not been clear whether these leathery-winged flying reptiles had feathers of different colours like modern-day birds.

Volume 604 Issue 7907

In this week’s issue, Aude Cincotta and her colleagues present evidence that not only did pterosaurs have feathers but that the feathers probably had varied coloration. The researchers analysed a partial skull of Tupandactylus, found in Brazil and dated to around 113 million years ago. They identified two types of feather along the base of the crest, one of which featured branched structures very similar to modern feathers. They also found pigment-producing organelles in both types of feather and the skin on the head crest. The team suggests that these coloured feathers would have been used in visual communication and that their presence in Tupandactylus indicates the ability to manipulate feather colour stretches back farther than was previously realized.

Life speed

Cells acquire mutations throughout life, a process that is known to give rise to cancer and has been proposed to contribute to ageing. There is little knowledge, however, about the rate at which mutations accumulate in species other than humans, and whether this rate is influenced by biological traits such as lifespan or body size. In this week’s issue, Alex Cagan, Adrian Baez-Ortega and colleagues address these questions. The researchers studied the speed at which mutations accumulate during life in 16 mammalian species and found that the number of mutations increases by a roughly constant amount each year. They also observed that the molecular processes causing mutations are broadly similar across species. Crucially, the team identified a strong anticorrelation between lifespan and mutation rate: longer-lived species accrue mutations at a slower pace than shorter-lived ones, such that different species have roughly the same number of mutations by the end of their respective lifespans.
