The miniature sheet presents a few of the dinosaurs and ancient reptiles together with their habitat whose fossils have been found in the Bakony hills in Hungary. The top row of the miniature sheet of six different stamps consists of the quadrupedal herbivorous Ajkaceratopskozmai, the small, at most turkey-sized, probably pack-hunting Pneumatoraptorfodori, and the dragon of the Bakony, the omnivorous flying reptile with a wingspan of about 3.5 to 4 metres named Bakonydracogalaczi. In the bottom row, the 4 to 4.5 metre long, quadrupedal herbivorous armoured dinosaur Hungarosaurustormai, the at most 1 metre long short-nosed Iharkutosuchusmakadii, which taxonomically can be placed among modern crocodiles, and the aquatic apex predator at the time, a mosasaurus that adapted to a freshwater environment, Pannoniasaurusinexpectatus, can be seen. The special postmark shows the beak of the 1.5 metre long, herbivorous Ajkaceratopskozmaiwith a small horn and characteristic parrot-like bill.
