The fossil Kimberella quadrata was originally described from late Precambrian rocks of southern Australia. Reconstructed as a jellyfish, it was later assigned to the cubozoans (‘box jellies’), and has been cited as a clear instance of an extant animal lineage present before the Cambrian. Until recently, Kimberella was known only from Australia, with the exception of some questionable north Indian specimens. We now have over thirty-five specimens of this fossil from the Winter Coast of the White… 

Paleontological evidence for the supposed precambrian occurrence of mollusks

AbstarctThe paper discusses a group of the Late Vendian fossils supposedly related to mollusks. The fossils include imprints with some anatomical characteristics of mollusks, traces resembling

Precambrian animal life: probable developmental and adult cnidarian forms from Southwest China.

TLDR
The new observations reported in this paper indicate the existence of a diverse and already differentiated cnidarian fauna, long before the Cambrian evolutionary event.

An Early Cambrian problematic fossil: Vetustovermis and its possible affinities

TLDR
All the characters displayed in this 525 million-year old soft-bodied animal fail to demonstrate clear affinity with molluscs or any other known extant or extinct animal groups, but argue for representing an independently evolved animal group, which flourished in Early Cambrian and possibly in Middle Cambrian time.

Small Bilaterian Fossils from 40 to 55 Million Years Before the Cambrian

TLDR
Ten phosphatized specimens of a small animal displaying clear bilaterian features have been recovered from the Doushantuo Formation, China, and provide the first evidence confirming the phylogenetic inference that Bilateria arose well before the Cambrian.

New reconstruction of Kimberella, problematic Vendian metazoan

TLDR
Six groups of fossil remains of Kimberella quadrata are described, which represent the imprints of the body in different types of preservation and also the feeding traces and mucus secretions.

Ediacara-type fossils in Cambrian sediments

Fossil assemblages that preserve soft-bodied organisms are essential for our understanding of the composition and diversity of past life. The worldwide terminal Proterozoic Ediacara-type fossils

A Fresh Look at Dickinsonia: Removing It from Vendobionta

TLDR
This research is not only removing Dickinsonia from Vendobionta, but also bringing the fossil record of ctenophores forward to 20 million years before the Cambrian “explosion”.

The paper gives an overview of the modern hypotheses on the origin of the phylum Mollusca and the formation of its main classes. The Cambrian stage of molluscan evolution is characterized based on

A soft-bodied mollusc with radula from the Middle Cambrian Burgess Shale

TLDR
Odontogriphus omalus is interpreted to be members of an early stem-group mollusc lineage that probably originated in the Neoproterozoic Ediacaran Period, providing support for the retention of a biomat-based grazing community from the late Precambrian Period until at least the Middle Cambrian.

Lower Cambrian Vendobionts from China and Early Diploblast Evolution

TLDR
A frondlike fossil, Stromatoveris, is described from the Lower Cambrian Chengjiang Lagerstätte (Yunnan, China) that is strikingly similar to Ediacaran vendobionts and has important implications for the early evolution of this phylum and related diploblasts, some of which independently evolved a frondose habit.

TLDR
Evidence from the fossil record can be combined with that from molecular phylogenetic trees to suggest that the last common ancestor of (i) protostomes and deuterostomes was a roundish worm with a blood vascular system and (ii) of arthropods and annelids was similar, with a hydrostatic hemocoel, among trace makers of the late Precambrian.

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.

The Phylum Vendobionta: a sister group of the Eumetazoa?

TLDR
It is hypothesized that the Vendobionta are cnidarian-like organisms that lacked cnidae, and this analysis differs from existing interpretations of the Ediacaran fossils as ancestors of extant cNidarians in that it does not regard any of these forms as either polypoid or medusoid.
