Morphology
Reconstruction
Parvibellus is small panarthropod with length of around 5 mm (0.20 in). There is no evidence that Parvibellus had eyes. Many aspects of its morphology, such as its 11 pairs of trunk swimming flaps, and ventrally directed circular mouth, suggest a close relationship with stem-group arthropods such as the "gilled lobopodians" Kerygmachela and Pambdelurion, opabiniids and radiodonts.[1]
