Abstract. Archaeocyaths are the most abundant sponges from the Cambrian period, having formed the first animal reef communities more than 500 million years ago. The Archaeocyatha are index fossils for correlating rocks of similar ages globally because of their abundance, extensive geographic distribution, detailed anatomy, and well-established taxonomy. Their ecological significance remains incompletely explored, yet they are known to have strongly competitively interacted, unlike modern… Expand

Vertically migrating Isoxys and the early Cambrian biological pump
This work combines elliptical Fourier analysis of carapace shape with computational fluid dynamics simulations to demonstrate that Isoxys species likely occupied a variety of niches in Cambrian oceans, including vertical migrants, providing the first quantitative evidence that some Cambrian animals were adapted for vertical movement in the water column.

Plankton ecology and the Proterozoic-Phanerozoic transition
The major biogeochemical perturbations that mark the onset of the Phanerozoic might be a consequence, rather than a cause, of the Cambrian explosion; reduced C export due to zooplankton expansion explains the otherwise anomalous drop in 813C at the base of the Tom- motian. Expand
Present consensus is that archaeocyaths represent both a clade and a grade—Class Archaeocyatha and the archaeocyathan morphological grade—within Phylum Porifera. Expand
Controls on the diversity and structure of earliest metazoan communities: Early Cambrian reefs from Siberia
The dynamics of the earliest diverse skeletal metazoan communities known, the early Cambrian (Tommotian–Atdabanian) archaeocyathan sponge reefs, are revealed over a period of 20 million years from their first appearance ~ 535  million years ago until the first mass extinction event ~ 512 Ma. Expand
Depauperate skeletonized reef-dwelling fauna of the early Cambrian: Insights from archaeocyathan reef ecosystems of western Mongolia
Abstract Reef-dwelling organisms in the early Cambrian include typical members of the Cambrian Fauna such as trilobites, chancelloriids, and hyoliths. However, in comparison to later OrdovicianExpand
Restricted morphospace occupancy of early Cambrian reef-building archaeocyaths
Abstract. The evolution of novel morphologies can signify expansion of a clade into new niches. This can be studied in the fossil record by investigating the morphospace occupancy of organisms,Expand
Lower Cambrian archaeocyathan bioconstructions
Abstract Archaeocyatha are now confidently considered as a Class within the phylum Porifera. Regulares and Irregulares are no longer a systematic division, but have only ecological significance.Expand
Putative sponge biomarkers in unicellular Rhizaria question an early rise of animals
Fossil lipid biomarkers previously thought to be diagnostic of sponges (and thus indicative of animal life) are found to be preserved in unicellular Rhizarian protists, questioning a pre-Cambrian origin of spongees. Expand
Carbon isotopic evidence for photosynthesis in Early Cambrian oceans
Were the first metazoan reefs ecologically similar to modern tropical reefs, enabling them to persist under oligotrophic conditions? We tested the hypothesis of ecological similarity by employing aExpand
The Great Ordovician Biodiversification Event (GOBE): The palaeoecological dimension
Abstract The ‘Great Ordovician Biodiversification Event’ (GOBE) saw a spectacular increase in marine biodiversity at all taxonomic levels largely within the phyla established much earlier during theExpand
Functional analysis of archaeocyathan skeletal morphology and its paleobiological implications
Differences in flow pattern between the porous- and aporous-septate models suggest a hitherto unknown function for septa, a mechanism by which outer-wall leakage is avoided later in life. Expand
