Lower to Middle Cambrian shales of the Mount Cap Formation in the Mackenzie Mountains, northwestern Canada, host a variety of Burgess Shale-type macrofossils, including anomalocarid claws, several taxa of bivalved arthropod, articulated hyolithids, and articulated chancelloriids. Hydrofluoric acid processing has also yielded a broad range of organic-walled fossils, most of which are derived from forms more typically known as shelly fossils; e.g., trilobites, inarticulate brachiopods, small… 

Soft-bodied biota from the middle Cambrian (Drumian) Rockslide Formation, Mackenzie Mountains, northwestern Canada

Abstract. A new Burgess Shale-type Lagerstätte is described from the middle Cambrian (Series 3, Drumian) Rockslide Formation of the Mackenzie Mountains, Northwest Territories, Canada. The Rockslide

Beyond the Burgess Shale: Cambrian microfossils track the rise and fall of hallucigeniid lobopodians

TLDR
Hallucigeniids are revealed as an important and widespread component of disparate Cambrian communities from late in the Terreneuvian (Cambrian Stage 2) through the ‘middle’ Cambrian (Series 3); their apparent decline in the latest Cambrian may be partly taphonomic.

New records of Burgess Shale-type taxa from the middle Cambrian of Utah

TLDR
It is extended knowledge of such Middle Cambrian occurrences in Utah with reports of four taxa, including a putative megacheiran and a new species of a stem-group lophotrochozoan from the Spence Shale, which possesses a palisade of dorso-lateral spines that are more robust and numerous than the type species of Wiwaxia.

Taphonomy of exceptionally preserved fossils from the Kinzers Formation (Cambrian), southeastern Pennsylvania

The pelitic Emigsville Member of the Kinzers Formation (Cambrian), southeastern Pennsylvania, is a deposit of exceptional fossil preservation. It contains three main lithofacies that were part of a

BURGESS SHALE-TYPE PRESERVATION: A COMPARISON OF NARAOIIDS (ARTHROPODA) FROM THREE CAMBRIAN LOCALITIES

Abstract The chemical composition of well-preserved naraoiids from the Chengjiang, Kaili, and Burgess Shale biotas is compared. Gut diverticulae in samples from all three biotas contain C, P, and Fe,

Distribution of Chancelloriids in a Middle Cambrian Carbonate Platform Deposit, Taebaek Group, Korea

The onset of the Cambrian witnessed the diversification of “small shelly fossils (SSF)”, which affected carbonate depositional system. One of the problematic SSF, chancelloriids, are common

A cryptic record of Burgess Shale‐type diversity from the early Cambrian of Baltica

TLDR
A diverse assemblage of small carbonaceous fossils from the early Cambrian (Stage 4) File Haidar Formation of southeast Sweden and surrounding areas of the Baltoscandian Basin is reported, including exceptionally preserved remains of Burgess Shale-type metazoans and other organisms.

Bivalved arthropods from the Lower Cambrian Mernmerna Formation, Arrowie Basin, South Australia and their implications for identification of Cambrian 'small shelly fossils'

A WIDE RANGE OF ARTHROPODS with bivalved head-shields are known from the Cambrian. Many of these arthropods did not have mineralised exoskeletons, and consequently are known mainly from celebrated

Plywood‐like shell microstructures in hyoliths from the middle Cambrian (Drumian) Gowers Formation, Georgina Basin, Australia

Hyoliths are a group of Palaeozoic fossils with calcareous shells whose affinities remain controversial. As their shells were originally aragonitic, their fossils are usually coarsely recrystallized,

Articulated Halkieriids from the Lower Cambrian of North Greenland and their Role in Early Protostome Evolution

TLDR
The hypothesis of halkieriids and their relatives having a key role in annelid-brachiopod-mollusc evolution is in accord with some earlier proposals and recent evidence from molecular biology, but casts doubt on a number of favoured concepts.

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

A reassessment of the enigmatic Burgess Shale fossil Wiwaxia corrugata (Matthew) and its relationship to the polychaete Canadia spinosa Walcott

TLDR
Anatomical and histological comparison with modern organisms indicates that Wiwaxia sclerites are polychaete paleae (flattened setae) and that WiWaxia was a jawed annelid broadly related to the extantpolychaete families Chrysopetalidae and/or Aprhoditidae (Palmyra).

The cap‐shaped Cambrian fossil Maikhanella and the relationship between coeloscleritophorans and molluscs

TLDR
Maikhanella shells were formed through the embedding of spicules in secondary calcareous shell zubstance, and together with the polyplacophoran-like features of the Halkieria scleritome this forces a reconsideration of the phylogenetic relationships between coeloscleritophorans and molluscs.

Hyolitha: status of the phylum

TLDR
Reconstructions of the anatomy of hyoliths indicate that it is unlikely that both groups shared a common molluscan ancestor, therefore,hyoliths are probably not mollUScs.

Ontogeny of Bactrotheca and related hyoliths

  • J. Dzik
  • Geography, Environmental Science
  • 1980
TLDR
Data presented here document a high diversity of larval development within particular groups of hyoliths (Monoplacopho...), suggesting a planktotrophic mode of life for the larvae.

Biology of the Hyolitha

TLDR
Although the shell form and skeletal ultra-structure of hyoliths are of a molluscan type, the muscle insertions suggest that the hyolith cone is not homologous with the dorsal exoskeleton of primitive mollsuscs.

Aspects of the biology of Hyolitha (Mollusca)

TLDR
The Hyolithida were probably deposit feeders living in shallow water, and accordingly were tentaculate, and except for the more complex musculature associated with an elaborate operculum, Orthothecida are judged to have had a similar anatomy.
