Scientists discovered a new Cambrian penis worm, Kraytdraco spectatus, in the Grand Canyon, and a high school student created a detailed 3D animation illustrating how it might have fed and been swallowed, offering a rare glimpse into ancient marine life.
Hilarious images reveal how early palaeontologists' depictions of dinosaurs have evolved over time, from clumsy creatures resembling scaly rhinos to today's fearsome feathered beasts. The first dinosaur discoveries, including the megalosaurus and iguanodon, were initially thought to be giant lizards, leading to comical artistic interpretations. Modern understanding, aided by complete skeletons and fossilized feathers, has corrected many misconceptions, revealing that dinosaurs were more athletic, dynamic, and often feathered than previously thought. Ongoing debates among experts continue to shape our understanding of dinosaur appearance and behavior.
