35 real specimens from the Mesozoic Era, an epic period spanning 185,000,000 years of history, also known as the Age of Dinosaurs! Pre-orders for Age of Dinosaurs will ship once we have completed all Mini Museums for our Kickstarter backers. We expect this to happen in May of 2020. When you check out, you will be asked to provide your credit card information. However, we will not charge you until your Mini Museum is ready to ship.
