Diagnosis
ReferenceDiagnosis
M. Ghobadi Pour et al. 2011Fringe with pits on upper lamella dominantly radially arranged in relatively narrow, deep sulci, containing pits E1–2 and I1–2. I pits interior of I2 in radial alignment with sulci frontally, randomly distributed and out of radial alignment laterally and posterolaterally. Fringe with E1 complete; E2 developed abaxially very close to E1, diverging from it posterolaterally until maximum curve of fringe, then converging to it posteriorly. I1 and I3 complete; I2 very close to I3 frontally, with median two I2/I3 pit pairs merging; I2 increasing in distance from I3 laterally, but cannot be traced anterolaterally due to irregular arrangement of I pits between I1 and I3. Apart from I1 and I3, I pits irregularly arranged. Around four irregular arcs between I1 and I3 at anterolateral corners, up to eight posterolaterally. Lateral eye ridges and tubercles absent. Pygidium with five axial rings plus terminal piece.
