This example shows Skolithos burrows; d showing the three facies of facies association FA-2. Full size image. Reddish-green claystone facies (F3b) These facies are characterized by massive appearance and the absence of visible bedding. The dominant grain size is clay with the possibility of silts and sands towards the top.With coiling absent from diagnoses of Skolithos (Alpert, 1974), it is not advisable to retain any helical burrows under this ichnogenus and doing so would only further compound taxonomic issues. It is herein suggested that all helical Skolithos be reassigned to Gyrolithes if δ > 1 or Ichnogyrus if δ ≤ 1.
