The Beidazoon venustus had a hard outer shell similar to the Vetulicola. Beidazoon had a single band mouth. Its tail is asymmetrical and composed of a hard shell extending from the upper posterior, an axial lobe of seven segments, and a ventral lobe with four or five segments.[3] Shu suggests that the Beidazoon's shell was "beautifully ornamented with numerous nodes".[3]
