The Cretaceous crab revolution was a major diversification event of brachyuran crustaceans (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 ]
Carcinisation (American English: carcinization) is a form of convergent evolution in which non-crab crustaceans evolve a crab-like body plan. The term was introduced into evolutionary biology by L. A. Borradaile, who described it as "the many attempts of Nature to evolve a crab". [2]

Walking with Dinosaurs is a 2013 family film about dinosaurs set in the Late Cretaceous period, 70 million years ago. The production features computer-animated dinosaurs in live-action settings with actors John Leguizamo, Justin Long, Tiya Sircar, and Skyler Stone providing voice-overs for the main characters.
The Cretaceous Terrestrial Revolution (abbreviated KTR), also known as the Angiosperm Terrestrial Revolution (ATR) by authors who consider it to have lasted into the Palaeogene, [1] describes the intense floral diversification of flowering plants (angiosperms) and the coevolution of pollinating insects, as well as the subsequent faunal radiation of frugivorous, nectarivorous and insectivorous ...
