The Cretaceous crab revolution was a major diversification event of brachyuran crabs (also known as true crabs) that took place during the Cretaceous Period, from 145 to 66 million years ago. [ 1 ] [ 2 ] Nearly 80% of modern groups of crabs originated during this event. [ 3 ]
Some crab-shaped species have evolved away from the crab form in a process called decarcinisation. Decarcinisation, or the loss of the crab-like body, has occurred multiple times in both Brachyura and Anomura. [25] [26] However, there are varying degrees of carcinisation and decarcinisation. Thus, not all species can necessarily be distinctly ...

Glaessneropsoidea is a superfamily of fossil crabs. [1] They are found in rocks from Late Jurassic age to Late Cretaceous. [2] The 45 species in the superfamily are divided among 11 genera in four families: [1] Family Glaessneropsidae Patrulius, 1959.
