Youti (meaning "larva") is anextinct genus ofdinocarididarthropods from theCambrianMaotianshan Shales of Yunnan Province, China. It was described after using computational approaches to visualize the internal details preserved inside the fossil. The genus contains asingle species,Y. yuanshi, known from a larval individual preserved in acarbonatenodule. The internal organs were well-preserved by the fossilization process and it was possible to study the structure using synchrotronscanning electron microscopy andX-ray computed tomography. The specimen showslobopod legs, and aonychophora-like peripheralhaemolymph system. Based on its anatomical characteristics, Smith et al. place the species in the arthropod clade containingAnomalocaris,Opabinia,Pambdelurion andKerygmachela.[1]
