What to know about The revolution in dinosaur science started 50 years ago—here's what we have learned

The article discusses the scientific advancements in dinosaur research over the past 50 years, highlighting key discoveries such as methods to estimate dinosaur speed from footprints, the use of engineering techniques to analyze jaw movements, and the determination of dinosaur colors through melanosomes in fossilized feathers. It emphasizes the shift from speculative theories to evidence-based paleobiological methods.

What happened

The revolution in dinosaur science started 50 years ago—here's what we have learned Lisa Lock scientific editor Andrew Zinin lead editor The study of dinosaurs has been through a revolution in recent decades.

Why it matters

The story began half a century ago, when Robert McNeill Alexander, a professor of zoology at the University of Leeds, showed how the speed of an animal could be calculated from the spacing of its footprints and its body size.

Common ground

This formula worked both for modern and extinct animals and so, for the first time, the speed of a dinosaur could be estimated from a fossilized trackway.

Perspective signals

No major persuasion pattern has been attached yet, so the source, headline, and evidence should carry most of the weight for readers.
