Jinningella is a genus of sunellid arthropod. ^{[1] [2] [3]}

Description

Jinningella is similar to the genus Sunella and Combinivalvula in general anatomy, differing in the fact that no sexual dimorphism is known and the possession of anterodorsal nodes. ^{[1] [2]} It reached around 10 mm (1 cm). ^[3] Other sunellids reached similar sizes, Combinivalvula reached a similar size, Caudicaella specimens can be up to 12 mm (1.2 cm) and the largest Sunella fossil was roughly 15 mm (1.5 cm). ^{[1] [3]}

Distribution

Jinningella fossils are only found in the Chengjiang biota. ^[2]
