Remember when you were a kid, how the cheese seemed so tall? You thought it just seemed that way because you were shorter in comparison, but it actually was tall. Most likely, it was virgin, old-growth cheese, having never before seen man or cheese-cutter. In contrast, almost all cheese sold today is second growth cheese, much smaller than its old-growth brethren. The extinct cheeses of the Mesozoic era pictured at the bottom of this page lived over 200 million years ago and took an incredible 800 years to attain their massive size. Compare them to typical puny modern cheeses pictured immediately below.
