    • ‘The Penaeidae fall within the order Decapoda (class Malacostraca), which contains most commercially important crustacean species.’
    • ‘An alternate suggestion is that the Cretaceous and the Eocene were each times of rapid evolution within the Decapoda.’
    • ‘Other aspects of the morphology of Palaeopemphix that separate it from the Decapoda include the bivalved nature of the carapace and the strong development of the lateromarginal carina, or doublure.’
    • ‘Thus, the evolutionary history of the Decapoda, especially the Brachyura, may be more ancient than previously believed.’
