抄録

A natural assemblage of Ellisonia<i> sp. cf. <i>E. triassica Müller was recovered from the uppermost Permian close to the Permian-Triassic boundary in the Nabejiriyama section in the Mt. Ryozen area, Suzuka Mountains, central Japan. This natural assemblage and collections of similar ellisonids from the Taho Formation of Ehime Prefecture, southwestern Japan, demonstrate that the Ellisonia apparatus is composed of eight kinds of elements: breviform digyrate M, symmetrical S₀, extensiform digyrate S₁ and S₂, bipennate S₃ and S₄, and angulate P₁ and P₂ elements. The apparatus structure of Ellisonia is comparable to the standard 15-element plan of Carboniferous ozarkodinids and prioniodinids. The apparatus structure of the present natural assemblage is important in discussing the phylogenetic affinity of the genus Ellisonia.
