Examples of repeated preservational features in Saurichthys. a Localised disruption in the anterior part of the vertebral column resulting in separation of the skull from the otherwise articulated and complete body (PIMUZ T 529 from the Besano Formation); b a black eye spot in a juvenile of Saurichthys from the Besano Formation (PIMUZ T 548 from the Besano Formation); c a specimen showing strong curvature of the axial skeleton to the extent it breaks out of the body outline provided by the mid-dorsal and mid-ventral scale rows (arrow marked V) and articulation of the mid fin units that are separated from the remainder of the body (arrow marked MF) (PIMUZ T 4154 from the Cassina Beds); d section of the abdominal region of a Saurichthys focusing on the scale rows and axial skeleton that both show twisting (PIMUZ T 668 from the Besano Formation)
