[HTML][HTML] Animal origins: the record from organic microfossils
Accumulated records of organic microfossils span billions of years of Earth history. The
majority of this record consists of prokaryotes plus eukaryotes of a protistan grade, yet this …

The gnathobasic spine microstructure of recent and Silurian chelicerates and the Cambrian artiopodan Sidneyia: functional and evolutionary implications
Gnathobasic spines are located on the protopodal segments of the appendages of various
euarthropod taxa, notably chelicerates. Although they are used to crush shells and masticate …

Caught in the act: priapulid burrowers in early Cambrian substrates
The fossilized traces of burrowing worms have taken on a considerable importance in
studies of the Cambrian explosion, partly because of their use in defining the base of the …

Evolution of Bilateria from a Meiofauna Perspective—Miniaturization in the focus
Meiofaunal life forms are found all over the animal tree of life, and miniaturization seems to
have occurred within otherwise macrofaunal clades multiple times. While sponges, comb …

Exceptional soft tissue preservation reveals a cnidarian affinity for a Cambrian phosphatic tubicolous enigma
Exoskeletal dwelling tubes are widespread among extant animals and early fossil
assemblages. Exceptional fossils from the Cambrian reveal independent origins of tube …

A cryptic record of Burgess Shale‐type diversity from the early Cambrian of Baltica
Abstract Exceptionally preserved 'Burgess Shale‐type'fossil assemblages from the
Cambrian of Laurentia, South China and Australia record a diverse array of non …

Tube-dwelling in early animals exemplified by Cambrian scalidophoran worms
Background The radiation of ecdysozoans (moulting animals) during the Cambrian gave
rise to panarthropods and various groups of worms including scalidophorans, which played …

Small carbonaceous fossils (SCF s) from the T erreneuvian (lower C ambrian) of B altica
We describe a new assemblage of small carbonaceous fossils (SCF s) from diagenetically
minimally altered clays and siltstones of Terreneuvian age from the Lontova and Voosi …

Systematics, preservation and biogeography of radiodonts from the southern Great Basin, USA, during the upper Dyeran (Cambrian Series 2, Stage 4)
Anomalocaris, the most well‐known genus of the diverse stem euarthropod group
Radiodonta, was first reported over 100 years ago from the Burgess Shale (Canada). This …
