Siberion is an extinct genus of lobopodian from the Sinsk biota of Russia . Its anatomy, including the proboscis-like organ projecting from the face and prominent grasping first pair of appendages, suggests that xenusians like this organism may have been phylogenetically related to anomalocaridids, like Anomalocaris.[3]
