Diagnosis
ReferenceDiagnosis
P. Turner and S. Turner 1974The head scales are small and rounded with crenulated edges, resembling those of L. martinssoni. The transitional scales are more oak-leaf like in shape and become more diamond shaped with side notches anteriorly, resembling small scales of Katoporus species or Logania kummerowi Gross (Gross 1967). The body scales, as noted, can resemble those of Tu. pagei, and some are like those of L. cuneata. The rather specialised scales found on the articulated specimens from Scotland, with up to five posterior spines (Stetson 1931) have not been found. Probably they were too delicate and broke up easily.
