It's time for episode 21, and it's a special one. Instead of our usual format, we've skipped the interview this week to take our time to talk about one of our oldest, most special and most cherished palaeoart books yet. After all, what Vintage Dinosaur Art is more worthy of an in-depth look than Alice B. Woodward's Golden Age illustrations in Henry Knipe's Evolution in the Past, all the way from 1912? The fact that two-thirds of us have come down with a brutal cold has nothing to do with it, I promise.

What's all this talk about a Golden Age of illustration? What, if anything, is a rhabodontid? Is Natee secretly a total T. rex stan? Are we all going to break into a Gilbert & Sullivan song and dance number? (No.) And what did the scientists of the 1910s make of the infamous butt-brain hypothesis? Find out in this riveting episode.
