Youti (meaning "larva") is an extinct genus of dinocaridid arthropods from the Cambrian Yu'anshan Formation of Yunnan Province, China. It was described after using computational approaches to visualize the internal details preserved inside the fossil. The genus contains a single species, Y. yuanshi, known from a larval individual preserved in a carbonate nodule. The internal organs were well-preserved by the fossilization process and it was possible to study the structure using synchrotron scanning electron microscopy and X-ray computed tomography. The specimen shows lobopod legs, and a onychophora-like peripheral haemolymph system. Based on its anatomical characteristics, Smith et al. place the species in the arthropod clade containing Anomalocaris, Opabinia, Pambdelurion and Kerygmachela.[1]
