But a recent study from scientists at the University of Cambridge and Imperial College London has put some numbers behind our collective acquired knowledge of dinosaurs. It appears that much of what we know about dinosaurs could potentially change over the next 20 years.

The science is simple. Everything we know about dinosaurs is essentially derived from the fossil record. And over the last ten years there has been a dramatic increase in additions to that fossil record. In layman's terms: we're discovering more dinosaurs at rapid rate, which means we're constantly acquiring new, concrete examples of how dinosaurs actually lived.
