Current identification/main database link: Trigonastrum Haeckel 1887
Original Description
Porodiscida with three forked, chambered arms, connected by a patagium. (Arms and angles between them either equal or unequal.)
The genus Trigonastrum differs from the preceding Chitonastrum, its ancestral form, in the development of a patagium between the arms. It bears therefore to the latter the same relation that Euchitonia does to Rhopalastrum.
Etymology: Greek trigonastrum = triangular star"
