Review: Pterygotus (Dinotales series 7 by Kaiyodo)

Kaiyodo has to be one of the best prehistoric animal lines out there. At a small size, they gave us a wide spread of species from across earth history in glorious detail and beautiful paint schemes. Today’s review shows just this: Pterygotus, a Silurian Sea Scorpion, one of the largest arthropods ever known, reaching a body length of 5.7 ft.

The interval of Earth’s history which shows fossil evidence of animals is known as the Phanerozoic Eon (literally “visible animals”). The Phanerozoic is divided into three Eras. We live in the Cenozoic, which was preceded by the Mesozoic (during which dinosaurs were the largest terrestrial animals).
