Doushantuo phosphorites at Weng’an, Guizhou Province, provide a unique opportunity for the study of early evolution of multicellular organisms, including metazoans. Our light microscope and SEM observations, however, do not substantiate a sponge spicule interpretation of spicular structures. No convincing axial canals have been seen in the observed spicule population. Instead, the coexistence of some monaxonal spicules with clearly diagenetic crystal fascicles and dumbbells suggest that these…

Phosphatized Acanthomorphic Acritarchs and Related Microfossils from the Ediacaran Doushantuo Formation at Weng'an (South China) and their Implications for Biostratigraphic Correlation

Abstract The Doushantuo Formation at Weng'an in Guizhou Province, South China, is best known for animal embryo-like microfossils preserved in phosphorites. However, this unit also contains a diverse

A giant foraminifer that converges to the feeding strategy of carnivorous sponges: Spiculosiphon oceana sp. nov. (Foraminifera, Astrorhizida).

Spiculosiphon species collect and arrange sponge spicules with high selectivity to recreate a body morphology that strongly converges to that of some carnivorous sponges, which allows these predatory foraminifera to exploit a prey capturing strategy similar to those of the carnivoroussponges.

Giving the early fossil record of sponges a squeeze

Twenty candidate fossils with claim to be the oldest representative of the Phylum Porifera have been re‐analysed and it is shown that no Precambrian fossil candidate yet satisfies all three of these criteria to be a reliable sponge fossil.

This is the first crown‐group demosponge described from the early Cambrian and provides the most reliable calibration point currently available for phylogenetic studies.

PHOSPHATIZED ANIMAL EMBRYOS FROM THE NEOPROTEROZOIC DOUSHANTUO FORMATION AT WENG'AN, GUIZHOU, SOUTH CHINA

Phosphorites of the uppermost Neoproterozoic Doushantuo Formation exposed at Weng'an, South China, contain globular microfossils characterized by distinctively sculpted outer coverings and precise patterns of cell division, which support their reinterpretation as the eggs and embryos of early animals.

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.

Precambrian sponges with cellular structures

The fauna indicates that animals lived 40 to 50 million years before the Cambrian Explosion, and the presence of possible amphiblastula larva suggests that the calcareous sponges may have an extended history in the Late Precambrian.
