A forgotten leg bone from a 1963 dig in Zambia just flipped the script on dino history. Turns out, early dinosaurs (or their close cousins, silesaurs) might’ve been way bigger than we imagined—maybe even the biggest herbivores around! Scientists are now rethinking whether dinos started out huge and actually shrank over time. Wild, right? And all because someone finally took a second look at a dusty old museum fossil. Sometimes, the real game-changers are hiding in plain sight! #Science #Dinosaurs #FossilFinds
