[PDF][PDF] The evolutionary origins of the Hemichordata (Enteropneusta & Pterobranchia)–A review based on fossil evidence and interpretations.
J MALETZ - Bulletin of Geosciences, 2024 - geology.cz
Few fossils demonstrate the presence of the Hemichordata (Enteropneusta, Pterobranchia–
excluding benthic and planktic Graptolithina) in the early Palaeozoic. Many of these early …

[HTML][HTML] Thickness of the stratigraphic record of Britain: How the fidelity of geological and fossil data is unrelated to rock quantity
The sedimentary-stratigraphic record is the principal repository of empirical historic evidence
for evolution and deep time environments. However, the record has a temporal …

Protomelission is an early dasyclad alga and not a Cambrian bryozoan
J Yang, T Lan, X Zhang, MR Smith - Nature, 2023 - nature.com
The animal phyla and their associated body plans originate from a singular burst of
evolution occurring during the Cambrian period, over 500 million years ago. The phylum …

Ediacaran origin and Ediacaran-Cambrian diversification of Metazoa
The timescale of animal diversification has been a focus of debate over how evolutionary
history should be calibrated to geologic time. Molecular clock analyses have invariably …

A new salinity-based model for Cryogenian Mn-carbonate deposits
The genesis of manganese (Mn)-carbonate deposits in the Cryogenian Datangpo Formation
(∼ 662.9–654.5 Ma), Nanhua Basin, South China remains controversial. Here, we combine …

The role of clay minerals in the preservation of Precambrian organic‐walled microfossils
Precambrian organic‐walled microfossils (OWMs) are primarily preserved in mudstones and
shales that are low in total organic carbon (TOC). Recent work suggests that high TOC may …

Life in the Cambrian shallows: Exceptionally preserved arthropod and mollusk microfossils from the early Cambrian of Sweden
BJ Slater - Geology, 2024 - pubs.geoscienceworld.org
Abstract Burgess Shale–type (BST) Lagerstätten record an exceptional variety of Cambrian
soft-bodied fauna, yet these deposits are typically restricted to outboard depositional …

A peritidal Burgess‐Shale‐type fauna from the middle Cambrian of western Canada
Abstract Burgess‐Shale‐type (BST) faunas have proven critical for map** the Cambrian
assembly of animal‐dominated ecosystems, but have so far only been reported from fully …

Spatiotemporal distribution and morphological diversity of the Cambrian Wiwaxia: New insights from South China
Wiwaxia is a well-known Cambrian animal and a relative of annelids and molluscs,
characterized by its densely arranged, imbricated dorsal sclerites. Despite its prevalence in …

Cambrian 'sap-sucking'molluscan radulae among small carbonaceous fossils (SCFs)
BJ Slater - Proceedings of the Royal Society B, 2023 - royalsocietypublishing.org
Molluscs have produced an extensive fossil record, owing to the prevalence of robust
biomineralized shells among this clade. By contrast, most other components of molluscan …
