Still Waters Posted Saturday at 11:36 AM #1 Share Posted Saturday at 11:36 AM (IP: Staff) · It’s sometimes difficult to imagine how the planet we call home, with its megalopolis cities and serene farmlands, was once dominated by dinosaurs as big as buses and five-storey buildings. But recent research has helped deepen our understanding of why dinosaurs prevailed: the answer may lie in their special bones, structured like Aero chocolate. Brazilian palaeontologist Tito Aureliano found that hollow bones filled with little air sacs were so important to dinosaur survival, they evolved independently several times in different lineages. According to the study, aerated bones evolved in three separate lineages: pterosaurs, technically flying reptiles, and two dinosaur lineages theropods (ranging from the crow-sized Microraptor to the huge Tyrannosaurus rex) and sauropodomorphs (long-necked herbivores including Brachiosaurus). The researchers focused on the late Triassic period, roughly 233 million years ago, in south Brazil. https://theconversation.com/bones-like-aero-chocolate-the-evolution-adaptation-that-helped-dinosaurs-to-fly-201805 https://www.nature.com/articles/s41598-022-25067-8 4 Top Link to comment Share on other sites More sharing options...
