A very remarkable species of Spongophyllum from the Upper Silurian rocks of New South Wales
Abstract
The subject of the present paper first came under my notice whilst engaged in a geological traverse of the Upper Silurian beds exposed in the course of the Yass River, between the town of the same name and the Devil's Punch-bowl, near the Yass-Murrumbidgee Rivers Junction. The specimens so obtained were subsequently augmented by additions made by Mr. A. T. Shearsby.
Genus Spongophyllum, Edwards and Haime,1851
