Synonyms
  • Eccentrotheca guano was named by Bengtson et al. (1990) [Bengston in Bengston et al. 1990 = Eccentrotheca cf. kanesia Landing et al 1980 in Laurie 1986 446 f. 9A-E]. Its type specimen is SAMP30596, a valve, and it is a 3D body fossil. Its type locality is 6429RS103 - Horse Gully, which is in an Atdabanian carbonate grainstone in the Kulpara Limestone Formation of Australia.

    It was synonymized subjectively with Kulparina rostrata by Skovsted et al. (2015).

Balthasar Skovsted, Holmer and Brock, p. 1143, figs 1A, G, 2A–C.]. Its type specimen is SAMP 42537 and is a 3D body fossil.

    It was synonymized subjectively with Kulparina rostrata by Skovsted et al. (2015).

Diagnosis
ReferenceDiagnosis
C. B. Skovsted et al. 2011 (Eccentrotheca helenia)Scleritome construction as for genus. Disarticulated sclerites vary from low, cap-shaped with variable dorsal outline, to high, laterally compressed cap-shaped sclerites with gently curved basal aperture. Laterally compressed sclerites evenly expanding and usually clearly triangular in lateral profile. Differ from Eccentrotheca kanesia by the more regular increase in apertural length, the more moderate helical twist of triangular sclerites and the absence of a duplicature in low, cap-shaped sclerites. Laterally compressed sclerites differ from L sclerites of Paterimitra and Kulparina (i.e. ‘Eccentrotheca’guano) by the relatively low height, straight-sided triangular profile and less pronounced twisting.
C. B. Skovsted et al. 2015Tommotiid with scleritome comprising two distinctive sclerite types: symmetrical pyramidal S sclerites and high, laterally compressed, asymmetrical L sclerites. S sclerites with elongated, narrow lateral plates, strongly flexed toward posterior. Anterior plate subtriangular to slightly U-shaped. L sclerites high, irregular, extremely variable, but generally with strong lateral compression and tendency toward ontogenetic fusion.
Differing from Sunnaginia and Eccentrotheca by presence of bilaterally symmetrical sclerites. Differing from Paterimitra by triangular cross section and concave anterior plate in S sclerites, lack of differentiated S2 sclerites, highly irregular morphology of L sclerites, and absence of polygonal surface micro-ornament.
