What does XUS mean?
- Xus yus is an extinct cheloniellid arthropod from the Silurian period of Wisconsin. While X. yus closely resembles other cheloniellids, such as Triopus or Duslia, X. yus can be easily distinguished from its relatives by the presence of a pair of raptorial limbs that extend from underneath the head region, or cephalon.
