Late Middle Cambrian Mail Change Limestone, a thin (b30 m) lime mudstone unit of the epeiric Middle and Late Cambrian Georgina Basin, Australia is unusually rich in epifaunal linguliform brachiopods, especially acrotretids. It is the only unit of thi

A well-preserved benthic, epifaunal assemblage of articulated sponges is described from the stone coal beds of the Lower Cambrian Hetang Formation at Lantian, southern Anhui Province, South China. These sponges are Meishucunian–Qiongzhusian (=Diand

Faunules of largely hexactinellid sponges have been collected from siltstones of Early Silurian Wenlock or latest Landovery age within the upper Road River Group from northern British Columbia. The assemblages include the new species: Protospongia co

The family Protospongiidae Hinde, comprising the genera Protospongia Salter and Diagonella Rauff — both first found in rocks of Middle Cambrian age — has long been considered to be the stem group of all later Hexactinellida. They are small, conic

The Middle Cambrian lower alum shale and the associated anthraconites are reexamined and revised bio- and lithostratigraphically. New finds of predominantly agnostid trilobites show that the sequence is far more restricted stratigraphically than hith

Early Cambrian Leptomitus zitteli Walcott, 1886, is a tubular, double-walled, demo-sponge from the Parker Slate of Vermont and is one of the few intact sponges of that age known. It occurs with skeletal fragments of ?Protospongia hicksi Hinde, 1887.

Salter, who was the first to introduce this Sponge to our notice, describes it as exhibiting a loosely reticulate skeleton, composed of large cruciform spicules, the rays of which lie all in one plane and cross each other at an angle of 80° He adds

Existence of Sinian to lower Paleozoic formations in this area is confirmed by discoveries made since 1957, by the faculty of the Geological Department of Nanking University, of abundant fossils including graptolites, trilobites and Protospongia. Pre
