Palaeoscolex Explained

Palaeoscolex is the type genus of the Palaeoscolecid worms, and served as a wastebasket taxon.^[1] until its taxonomy was revised and many of its taxa assigned to Wronascolex.^[2]

The type and only unequivocal species is P. piscatorum, known from mid-trunk segments.^{[3] [4]}
