Toys for the rich: Do multimillion-dollar dinosaur auctions erode trust in science?

More and more palaeontologists are ringing alarm bells about high-profile auctions in which dinosaur fossils sell for outrageous sums. The most recent example involves a 77-million-year-old ‘Gorgosaurus’ skeleton that Sotheby’s sold for over US$6 million in August 2022

Dinosaurs were in decline even before extinction, claim Chinese Academy of Sciences researchers

The researchers studied over 1,000 fossilised dinosaur eggs and eggshells from the Shanyang Basin in central China and obtained detailed age estimates of the rock layers by analysing and applying computer modelling to over 5,500 geological samples

Dinosaur footprints dating back 200 million years discovered on Wales beach

The latest findings reveal that the footprints are unique and not common worldwide; further research could disclose interesting facts about Triassic life in the UK

Dinosaur species were already in decline much before meteor strike, says study

Comet from solar system's edge triggered a winter that killed the dinosaurs 66 mn-years-ago: Harvard study

These long-period comets take about 200 years to orbit the Sun and we can expect similar impacts every 250 million to 750 million years.
