Meet MeganeuropsisA closer look at prehistoric invertebrates
Invertebrate is a broad term for animals without a backbone, not a single evolutionary family. The species here represent different groups, ages and ways of life.
Fossils can preserve striking details, but some unusual animals remain difficult to interpret. Each profile separates its fossil background from the imaginative colours and growth stages used in the game.
Are these illustrations scientific reconstructions?
No. The illustrations are stylized Dinosgacha game artwork. The linked profiles provide fossil context and references, while colours, expressions and growth-stage designs are artistic interpretations.
