Yanjiahella biscarpa is an extinct species of Early Cambrian deuterostome which may represent the earliest stem group echinoderm.
This species is known from the Fortunian Yanjiahe Formation (~541.0–534.6 Ma) in Hubei province, China and was first described by Guo et al. who had difficulty in assigning a taxonomy to the animal due to the shared nature of its features between the hemichordates and echinoderms.
