The renowned soft-bodied faunas of the Cambrian period, which include the Burgess Shale, disappear from the fossil record in the late Middle Cambrian, after which the Palaeozoic fauna dominates. The disappearance of faunas of Burgess Shale type curtails the stratigraphic record of a number of iconic Cambrian taxa. One possible explanation for this loss is a major extinction, but more probably it reflects the absence of preservation of similar soft-bodied faunas in later periods. Here we report… 

An Ordovician variation on Burgess Shale-type biotas

TLDR
The early stages of the GOBE is clarified by describing a new open-marine Konservat-Lagerstätte from the Early Ordovician of Wales, which includes many lineages typical of the Cambrian Burgess Shale-type biotas, but the most abundant groups were sponges, algae and worms, with non-trilobite arthropods being unexpectedly rare.

A new phyllopod bed-like assemblage from the Burgess Shale of the Canadian Rockies.

TLDR
The discovery of an extraordinary new soft-bodied fauna from the Burgess Shale is reported, and the presence of the stem arthropods Misszhouia and Primicaris, previously known only from the early Cambrian of China, suggests that the palaeogeographic ranges and longevity of Burgess Shales taxa may be underestimated.

Burgess Shale-type fossil assemblages provide a unique record of animal life in the immediate aftermath of the so-called “Cambrian explosion.” While most soft-bodied faunas in the rock record were

Survival of Burgess Shale-type animals in a Middle Ordovician deep-water setting

Exceptional preservation of non-biomineralized arthropods, sponges and vermiform taxa occurs in the Darriwilian (Middle Ordovician) Llanfallteg Formation of South Wales, UK. The assemblage contains
