Excerpt from Proceedings of the Royal Society of Victoria, 1897, Vol. 9: Edited Under the Authority of the Council The fossils are very variable in Size and Shape, but speaking generally they are cylindrical objects ranging up to about 3 mm. Or 4 mm. In diameter and to about 5 mm. In length. The two terminal plane faces of the cylinder are generally perpendicular to its long axis, and are pierced by a number of fine pores, which are apparent without the aid of a lens. The lateral wall of the cylinder is formed by closely applied threadlike cords which branch and anastomose, leaving narrow elongated pores between them, the long axis of the pores coinciding in direction with that of the cylinder. Usually the diameter of the cylinder slightly increases somewhat suddenly at each end. In many cases the joints are branched, three branches sometimes meeting at one point. The proportion of the length of the cylinder to its. Diameter varies greatly in different specimens. Some are very elongate, while others are żat discs, all grades between the two extremes being found. I. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
