Parallelodon aequalis Chapman 1908

Abstract

Parallelodon aequalis Chapman, 1908 Original source Chapman (1908): 39, pl. 4 fig. 57; originally as “aequalis ”. Type stratum and age “Silurian (Melbournian). In brown mudstone”; Melbourne Formation, Murrindindi Supergroup, lower Ludlow, Silurian. Type locality “ Yarra Improvement Works, S. Yarra”; South Yarra, County of Bourke, Victoria, Australia. Type material Holotype is a steinkern of a LV (P 7924). Stored in the collections of the Museums Victoria, Melbourne. Remarks Mentioned in the type catalogue of Gill & Davies (1968). The morphology of this species rather matches Schizodus King, 1844 (Trigoniida: Schizodidae). Systematic classification is therefore questionable (Amler & Friedel 2025).
