Abstract Trace fossils extend the history of early molluscan evolution because they have a higher preservation potential in siliciclastic strata, where body fossils are rare or absent, and also because they better record the activities of soft-bodied animals. The earliest mollusks are recorded by fan-shaped scratch arrays associated with death masks of the Ediacaran animal Kimberella. Cambrian traces––Climactichnites, Musculopodus, Radulichnus––and fecal pellets record giant, but shell-less… 
The origin of the animals and a ‘Savannah’ hypothesis for early bilaterian evolution

TLDR
The subtle remnants of Ediacara‐style taxa within the Cambrian suggest that they remained significant components of Phanerozoic communities, even though at some point their enabling role for bilaterian evolution was presumably taken over by bilaterians or other metazoans.

The rise and fall of stromatolites in shallow marine environments
Stromatolites are abundant in shallow marine sediments deposited before the evolution of animals, but in the modern ocean they are restricted to locations where the activity of animals is limited.
The Continuing Debate on Deep Molluscan Phylogeny: Evidence for Serialia (Mollusca, Monoplacophora + Polyplacophora)
TLDR
A new molecular clock indicates that molluscs had a terminal Precambrian origin with rapid divergence of all eight extant classes in the Cambrian, and the recovery of Serialia as a derived, Late Cambrian clade is potentially in line with the stratigraphic chronology of morphologically heterogeneous early mollusc fossils.
A Solution to Darwin's Dilemma: Differential Taphonomy of Ediacaran and Palaeozoic Non-Mineralised Discoidal Fossils
The eldonides, a group of non-mineralised asymmetrical discoidal fossils characterised by a coiled alimentary canal with circumoral tentacles and radially arranged internal lobes, are perhaps the
Sediment disturbance by Ediacaran bulldozers and the roots of the Cambrian explosion
TLDR
These trace fossils are the earliest clear representatives so far recorded of sediment bulldozing, an activity that may have had a negative impact on suspension-feeding and/or osmotroph communities, as well as on matgrounds, representing early examples of ecosystem engineering and trophic-group amensalism.

PALAEOBIOLOGY OF THE CLIMACTICHNITES TRACEMAKER
Abstract:  Trace fossils such as Climactichnites offer rare insights into the palaeobiology of Cambrian soft‐bodied animals, especially those that inhabited emergent sand flats and are not known from
Size of the earliest mollusks: Did small helcionellids grow to become large adults?
TLDR
The Spanish fossils provide direct evidence that at least some millimeter-scale helcionellids represent juvenile or larval shells of large, limpet-like mollusks, suggesting that the presumed generalized small size of Cambrian mollUSks may be a taphonomic artifact.
DEAD IN THEIR TRACKS—CAMBRIAN ARTHROPODS AND THEIR TRACES FROM INTERTIDAL SANDSTONES OF QUEBEC AND WISCONSIN

TLDR
Analysis of the fossil record of two famously problematic worms, Odontogriphus and Wiwaxia, reveals pronounced anatomical and histological discrepancies with molluscan analogues, such that they are more reliably interpreted as primitive features of the superphylum Lophotrochozoa.
Hermit arthropods 500 million years ago
Cambrian intertidal sandstones of North America record early excursions of large animals onto tidal flats, where continuous microbial films served as preservational agents for surface tracks. Whereas
Machaeridians are Palaeozoic armoured annelids
TLDR
A new machaeridian with preserved soft parts, including parapodia and chaetae, from the Upper Tremadoc of Morocco, demonstrating the annelid affinity of the group is described, showing that a lineage of annelids evolved a dorsal skeleton of calcareous plates early in their history.
New data on Kimberella, the Vendian mollusc-like organism (White Sea region, Russia): palaeoecological and evolutionary implications
TLDR
The taphonomic varieties of Kimberella provide new evidence of the animal's anatomy such as: shell morphology, proboscis, mantle, possibly respiratory folds and possibly musculature, stomach and glands.
