Forfexicaris valida was an egg-shapednektonic predatory arthropod from the Lower CambrianMaotianshan shaleLagerstätte about 1.5 centimetres long. This creature bears a superficial resemblance to ostracodcrustaceans, though, F. valida is not considered to be an ostracod, nor even a crustacean due to its leg morphology. Like its relative, Occacaris oviformis, F. valida also had a pair of "great appendages," though, it did not have paired spines. Unlike O. oviformis, F. valida's trunk did not extend beyond its carapace.
