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

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.

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

The Fezouata fossils of Morocco; an extraordinary record of marine life in the Early Ordovician

The discovery of the Fezouata biota in the latest Tremadocian of southeastern Morocco has significantly changed our understanding of the early Phanerozoic radiation. The shelly fossil record shows a

The Liexi fauna: a new Lagerstätte from the Lower Ordovician of South China

The Ordovician Lagerstätten record substantial amounts of excellent preservation and soft-bodied fossils during the Great Ordovician Biodiversification Event (GOBE). However, few Lagerstätten are

Fauna and ecology of the holothurian bed, Llandrindod, Wales, UK (Darriwilian, Middle Ordovician), and the oldest articulated holothurian

Unlike Cambrian Lagerstätten, Ordovician exceptionally preserved faunas generally differ substantially from each other in taxonomic composition, suggesting a much greater diversity of

ABSTRACT Discoveries, most of them recently, in more than thirty Lower and Middle Cambrian horizons with soft-bodied fossils have shown that forty-one of the genera occur also in the celebrated

Secular distribution of Burgess‐Shale‐type preservation

Burgess-Shale-type preservation is defined as a taphonomic pathway involving the exceptional organic preservation of non-mineralizing organisms in fully marine siliciclastic sediments. In the

Exceptionally preserved Late Ordovician biotas from Manitoba, Canada

There are few body fossil biotas known from early Paleozoic accretionary shorelines, and very few examples of Ordovician soft-bodied assemblages. This study documents two recently discovered biotas

Cambrian Lagerstatten: Their Distribution and Significance

The geological setting, biotic diversity and taphonomy of Cambrian soft-bodied Lagerstatten are reviewed with special reference to the Lower Cambrian Emu Bay Shale and Kinzers Formation, and the Middle Cambrian Stephen Formation.

Chitinozoans and the age of the Soom Shale, an Ordovician black shale Lagerstätte, South Africa

Isolated chitinozoans from the Soom Shale Member of the Cedarberg Formation, SW South Africa are described and provide a date of the latest Hirnantian–earliest Rhuddanian. The recovered chitinozoans

Post-Cambrian closure of the deep-water slope-basin taphonomic window

Exceptional faunas (Konservat-Lagerstatten that preserve traces of volatile nonmineralized tissues) are statistically overabundant in the Cambrian Period; almost all examples preserved in

A new Lagerstätte from the Middle Ordovician St. Peter Formation in northeast Iowa, USA

A new fossil fauna has been discovered from a recently recognized shale unit within the middle Ordovician St. Peter Formation in northeast Iowa. It contains a variety of invertebrates and

Preservation of Early Cambrian animals of the Chengjiang biota

The Chengjiang biota of Yunnan, China, documents the earliest extensive radiation of the Metazoa recorded in the fossil record. Gauging preservational bias is crucial in providing an assessment of

The Great Ordovician Biodiversification Event

The Global Ordovician Biodiversification Event (GOBE) was undoubtedly one of the most significant evolutionary events in the history of the marine biosphere. A continuous increase in ichnodiversity
