The third Mesozoic lizard that appears on the Czech Mint's silver coin from the Prehistoric World series is the Ankylosaurus. 

The ten-metre-long Ankylosaurus was a slow and clumsy herbivore. But it was certainly not defenceless. It was protected from the attacks of large predators by bone armour. Its broad head, topped with a beak, was covered with a series of horns and a layer of plates that fused with the skull bones. Its neck, back and flanks were covered by interconnected bone plates, growths and bumps that formed a compact armour. Its tail was topped with a massive bone club. This devastating defensive weapon, which the dinosaur carried just above the ground, could crush bones. The only vulnerable part of the ankylosaur's body was its unprotected abdomen. 

The reverse side of the coin was dedicated by the medal maker Petr Patka, DiS., to the depiction of the armoured ankylosaur in vivid colours, which were achieved using colouring technology. No photographs or computer graphics were used as a template - the author of the coin created an original painting. The embossed relief shows a Mesozoic wilderness with another ankylosaur defending itself against a tyrannosaur attack. The composition of the reverse side is supplemented with the inscription ANKYLOSAURUS. The obverse side of the coin, which is common to the entire cycle, then presents a fossilized skeleton of a tyrannosaurus and the English inscription PREHISTORIC WORLD. As the licence to issue the commemorative coins of the Czech Mint is granted by the Pacific island of Niue, the obverse side bears its necessary attributes - the national emblem, the nominal value of 1 DOLLAR (NZD) and the year of issue 2022. 

You can store the coin dedicated to the dinosaur in a collector's album that is full of interesting facts about the life of giant lizards.
