Guanshancaris

Guanshancaris is an extinct genus of amplectobeluid radiodont known from the Cambrian Stage 4 Guanshan Biota of southern China. It is only known from a single species. G. kunmingensis which was described in 2013 as a species of Anomalocaris^[1] before being placed in a new genus in 2023. Like many other radiodonts, it is only known from fragmentary remains, including its frontal appendages and the oral cone. It has been suggested to have been durophagous.^[2] Base on proportion of Anomalocaris, it is estimated to have reached up to 22.2–32.8 cm (8.7–12.9 in) long.^[3]
