Look At The Size Of Those Things!

摘要

Before my visit to Argentina, I had no real grasp of how large the very biggest dinosaurs could be. In the end, all it took was a glance at a single bone.rnI was in the Argentine Museum of Natural Sciences in Buenos Aires when I came across a vertebra from a dinosaur's back. What to compare it with? A human vertebra would fit comfortably in the palm of your hand. An elephant's would take two hands. At 1.6 metres tall, the vertebra in front of me was on another scale entirely - it would need a forklift truck to shift it.
