Sponge remains have been identified in the Early Vendian Doushantuo phosphate deposit in central Guizhou (South China), which has an age of approximately 580 million years ago. Their skeletons consist of siliceous, monaxonal spicules. All are referred to as the Porifera, class Demospongiae. Preserved soft tissues include the epidermis, porocytes, amoebocytes, sclerocytes, and spongocoel. Among thousands of metazoan embryos is a parenchymella-type of sponge larvae having a shoe-shaped morphology… Expand
Siliceous spicules in a vauxiid sponge (Demospongia) from the Kaili Biota(Cambrian Stage 5), Guizhou, South China
TLDR
Energy Dispersive X-Ray Spectrometry and Raman spectroscopy analysis indicate the presence of silica in the skeletal elements of these fossils, suggesting that this taxon possessed a skeleton comprised of spicules, the first confirmation of siliceous skeletal elements in fossils of the family Vauxiidae.

Records of a new spongelike group in the Riphean biota
New microfossils of presumably sponge organization grade have been recorded in the Meso-Neoproterozoic boundary beds of the Riphean Lakhanda Formation (Maya River, Uchur-Maya Region, southeasternExpand
Sponges: New Views of Old Animals1
TLDR
Sponges diverged from other animals earlier in evolutionary history than any other known animal group, extant or extinct, with the first sponge-related record in earth history found in 1.8 billion year old sediments. Expand
Skeletogenesis in problematic Late Proterozoic Lower Metazoa
This paper discusses supporting structures in problematic Late Precambrian Lower Metazoa, sponge and cnidarian affinity. These structure include aggregates of agglutinated mineral particles;Expand
Hexactinellid Sponge Spicules in Neoproterozoic Dolostone from South China
Abstract. Sponge spicules were extracted from dolostone in the lower part of the Neoproterozoic Doushantuo Formation in the Yangtze Gorges area (South China), which has an age of ∼630 millionExpand
Sponges (Porifera) as living metazoan witnesses from the Neoproterozoic: biomineralization and the concept of their evolutionary success
TLDR
It is concluded that it was the hard skeleton of the siliceous sponges that contributed to the successful evolution and survival of the Porifera during the last 500 Ma. Expand
Phragmodictya jinshaensis sp. nov., a hexactinellid dictyosponge from the Cambrian of Jinsha, south China
A new fossil species from Cambrian strata of Jinsha, south China, is interpreted as the earliest known hexactinellid dictyosponge. Phragmodictya jinshaensis sp. nov. occurs within the NiutitangExpand
Potential Ediacaran sponge gemmules from the Yangtze Gorges area in South China
Abstract Sponges are widely viewed as the most primitive metazoans. Sponge gemmule-like structures have been recovered from the lower part of the Doushantuo Formation in the Yangtze Gorges areaExpand

TLDR
Putative fossil embryos and larvae from the Precambrian phosphorite rocks of the Doushantuo Formation in Southwest China have been examined in thin section and identified what appear to be modern cnidarian developmental stages, including both anthozoan planula larvae and hydrozoan embryos. Expand

Ediacarian sponge spicule clusters from southwestern Mongolia and the origins of the Cambrian fauna
Carbon and strontium isotopic data are used to show that the earliest sponge spicule clusters and associated phosphatic sediments (with Anabarites ) from southwestern Mongolia are of Ediacarian age.Expand
The Late Precambrian fossil Kimberella is a mollusc-like bilaterian organism
TLDR
This work reconstructs Kimberella as a bilaterally symmetrical, benthic animal with a non-mineralized, univalved shell, resembling a mollusc in many respects, important evidence for the existence of large triploblastic metazoans in the Precambrian and indicates that the origin of the higher groups of protostomes lies well back in the precambrian.

Functional biology and ecology of Archaeocyatha
TLDR
The Archaeocyatha, an early Cambrain group of calcified sponges, were the first skeletal metazoans to develop a modular habit and to be associated with reefs, and show the predicted ecological changes with the appearance of modularity. Expand
New data on multicellular thallophytes and fragments of cellular tissues from Late Proterozoic phosphate rocks, South China
TLDR
New fossil forms discovered from the local rock bed demonstrate the possible existence of a community with relatively high diversity in Wengan shallow sea and confirms that an evolutionary radiation of mctaphylcs look place during Ediacaran time, shortly after the Nantuo glacial epoch. Expand

Molecular Evidence for Deep Precambrian Divergences Among Metazoan Phyla

It is suggested that invertebrates diverged from chordates about a billion years ago, about twice as long ago as the Cambrian, which suggests a prolonged radiation of animal phyla. Expand
