Scientists investigating a 66-million-year-old mystery have revealed that a bird feather embedded in fossilized dinosaur excrement suggests that the ancestors of modern birds who survived the dinosaur-killing asteroid that also wiped out all other ancient bird species benefited from the waterproofing properties of their feathers.
The newly analyzed bird feather fossil that provided the missing clues comes from an extinct bird group called Hesperornithiforms and not from the ancestor of modern birds, Neornithes.
However, the team said subtle differences between the species suggest previous theories crediting adaptation to water diving as the key to Neornithes’ survival were likely on the right track.
When a huge piece of space rock slammed into Earth, killing off virtually all dinosaur species save the ancestors of modern birds, the event also left behind a 66-million-year-old mystery. How did these ancient avians survive this apocalyptic event, resulting in every bird species we see today?
Jingmai O’Connor, the associate curator of fossil reptiles at the Field Museum in Chicago, said her career has been spent analyzing fossils to try to answer this single, critical question. However, unlike the new poop-encased bird feathers, most were not so ‘naturally’ protected from the ravages of time.
“It’s such a beautiful, well-preserved feather, from such an unexpected source, and it’s exciting that it could help us answer this huge question in paleontology,” explained the lead author of a study detailing the new analysis. “As far as I know, no one has ever thought to look for feathers or to study feathers in coprolites, so this project was really exciting.”
Researchers discovered the ancient bird feather in 2016 in Montana. Although she initially suspected it could be a coprolite rock (fossilized feces), O’Connor said she couldn’t confirm the theory for a decade.
The situation changed when O’Connor and Nate Carroll, a co-author of the paper and paleontologist at the Carter County Museum in Ekalaka, Montana, gained access to the micro-CT scanner at USC’s medical campus in Los Angeles, California. According to O’Connor, that’s when “the full feathery fabric of this fossil feces” started to finally reveal itself.
“Every hour processing the data revealed another feather, another scale, another bone—in stunning 3D,” Carrol also recalled.
Along with multiple feathers and tiny fish scales, the ancient dinosaur poop, which may have come from a Tyrannosaurus Rex, also contained legs from a hesperonithiform bird.
O’Connor said hesperonithiforms were ancient aquatic birds with similarities to modern loons. Critically, these cousins of the modern bird ancestor group had evolved specialized feet to hunt for fish by diving deep into the water.
“The feathers showed adaptations for being underwater that we see in living aquatic birds,” O’Connor explained.
Notably, the team said this evolution likely cost ancient hesperonithiforms like the one that was consumed by a dinosaur the ability to fly.
Although the bird group represented by the fossilized feather did not survive the dinosaur-killing asteroid, its connection to the ancestor of modern birds appears to support a previously proposed theory that adaptation to water may have helped Neornithes survive. O’Connor said she thinks that small differences in the feathers of the two ancient bird species hold the answer to a 66-million-year-old mystery.
“We think the types of feathers that these birds had, and/or the way they molted those feathers, may have been one of the underlying causes of the selectivity of the end-Cretaceous mass extinction,” the researcher explained, adding that this is “essentially why some birds died out and why others survived.”
Specifically, O’Connor pointed to the “smaller, fuzzy, primitive body feathers” found on the extinct bird “that we associate with dinosaurs and enantiornithines” alongside more modern-looking waterproof adaptations.
The team said that these evolutionary relics suggest that hesperornithiforms like the one that left behind its feathers were an evolutionary bridge between older bird groups and the Neornithes that survived the cosmic collision. Even more critically, the team said these earlier feather structures may not have retained heat as effectively as Neornithes feathers, allowing one species to survive the asteroid and another to die in the extreme cold that followed.
“The hesperornithiforms retain primitive feather types that may not have been as efficient for insulation as modern plumaceous feathers, and that could explain why they went extinct along with the enantiornithines,” O’Connor explained.
The study “Bird feathers from a Late Cretaceous coprolite” was published in Current Biology.

Lançado originalmente em 2022, o aplicativo Sunbird possui como premissa integrar a experiência do iMessage em dispositivos Android. No entanto, algum tempo depois, o serviço foi encerrado e o app, removido do Google Play devido a preocupações envolvendo privacidade e segurança.
Depois de já ter lançado, em 2024, uma versão beta do seu (então) novo aplicativo, a equipe por trás do serviço anunciou o seu retorno definitivo, afirmando que a nova configuração soluciona essas questões e que “qualquer mensagem é protegida em trânsito e descartada assim que é entregue”, enquanto as mídias enviadas ou recebidas são excluídas “normalmente em até 48 horas, e nunca além de 72 horas”.
Muitos devem estar se perguntando, porém, o motivo que leva alguém a optar pelo Sunbird considerando que a Apple já adotou o suporte ao padrão RCS 1Rich communications service, ou serviço de comunicação rico. no iOS, facilitando a comunicação com dispositivos Android pelo app Mensagens (Message). Essa é a explicação do serviço:
Em 2024, a Apple passou a oferecer suporte ao RCS nos iPhones, o que melhorou alguns aspectos básicos, como a qualidade das fotos e os indicadores de digitação. No entanto, os resultados são inconsistentes, e a mudança não permitiu que usuários de Android se tornassem membros plenos de grupos do iMessage. Reações, respostas e recursos de grupo do iMessage frequentemente falham quando há um celular Android no chat, e as mensagens enviadas por Androids continuam aparecendo em balões verdes.
Segundo Danny Mizrahi, CEO 2Chief executive officer, ou diretor executivo. da Sunbird Messaging, o aplicativo vai além de simplesmente oferecer balões azuis aos usuários de Android. O executivo afirma que recursos do iMessage (como reações, respostas, vídeos de alta qualidade e gerenciamento de grupos) funcionam perfeitamente no Sunbird para Android.
O Sunbird também introduz novos recursos, como uma nova caixa de entrada prioritária, com abas “Principal” e “Secundária”, de modo que as conversas individuais e os grupos com quem o usuário mais interage permanecem em destaque na aba “Principal”, enquanto mensagens rotineiras — como códigos de verificação e contatos de números desconhecidos — são direcionadas à aba “Secundária”.
Futuramente, o app ganhará ainda a Sunbird Intelligence, um conjunto de recursos de inteligência artificial que operam localmente. Entre as funções está o “Catch Me Up”, que oferecerá aos usuários um resumo consolidado de tudo o que perderam em suas conversas. Ele também terá um assistente integrado que poderá realizar ações como redigir uma resposta ou mover uma conversa entre categorias.
Ainda não se trata, porém, da versão final do Sunbird, e sim da versão “beta aberto”; no entanto, não há mais um processo de inscrição nem lista de espera. Ademais, agora o aplicativo conta com opções de assinatura interna (US$3 mensais ou US$25 anuais).
O Sunbird já está disponível no Google Play.

An innovative new approach to building safer, more efficient small unmanned aerial vehicles is taking a cue from nature.
Anticipating worsening turbulence due to environmental concerns in the coming years, engineers studying the unmatched hovering ability of kestrels hope to reverse engineer the secrets of their exceptional flight capabilities to help assemble better future drones.
Smaller drones, known as sUAVs, have a range of different applications that include delivery services, photography, and more. However, wind conditions can often cause turbulence that either grounds them temporarily or, when caught off guard, can lead to their destruction.
Now, a team of researchers has published their findings in the Journal of the Royal Society Interface, which details an ongoing collaboration between RMIT University and the University of Bristol that seeks to overcome such issues by building drones that operate more like some of nature’s best flyers.
Specifically, the nankeen kestrel is an avian species whose amazing prowess while flying during adverse conditions still confounds researchers. To unravel the secrets of their flight, the researchers used motion capture technologies made possible in RMIT’s special Industrial Wind Tunnel facility, one of the largest such facilities anywhere on the Australian continent.
“Birds don’t rely on a single response to wind gusts,” according to RMIT researcher Matt Penn. “They constantly adjust their wings and tails to stay balanced, while the natural flexibility of their feathers and joints helps absorb sudden changes in airflow.”
“They can also sense disruptions very quickly, which allows them to respond almost instantly and maintain control,” added Penn, one of the team members who co-led the studies into how birds can cope with turbulence.
According to Penn and his colleagues, these birds possess a range of unique strategies that help them overcome the dangers of turbulence, which help them navigate under conditions that would cause most sUAVs to come tumbling from the sky.
To attempt to understand what makes kestrels such adept fliers, the team created a robotic replica to mimic some of their key flight movements and characteristics, which allowed the team to unravel some of the secrets to how these incredible birds perform.
“By creating a robot replica, we were able to measure how specific movements were contributing to steadiness in flight,” said Dr Mario Martinez Groves-Raines, a researcher now with the Royal Veterinary College in London, adding that precision measurements of kestrel flight that normally could not be achieved in nature were possible using the team’s robotic version.
“We uncovered several unique techniques behind the kestrel’s impressive stability,” Groves-Raines said. “Many of these techniques have the potential to improve [the] manoeuvrability of small aircraft, which encounter similar challenges to kestrels.”
“This research shows what’s possible when engineers look to nature for solutions,” added RMIT senior researcher Associate Professor Abdulghani Mohamed.
“Our findings open new pathways for designing aircraft that can better handle turbulence.”
Going forward, the researchers say they hope to apply their findings toward the construction of novel sUAVs, which can help future drones operate safely and more efficiently, much like their agile avian forebears.
Ultimately, similar engineering in the coming years may have applications that extend well beyond just drone flight, and could also help to ensure safe operations for much larger aircraft.
The team reported their findings in a pair of new studies, ‘Bridging the Gap: A Review of Gust Mitigation in Birds and Small UAVs’, and ‘Stability and control benefits of coupled wing and tail morphing in kestrel wind-hovering flight explored using a robot replica’, both of which were published in the Journal of The Royal Society Interface.
