Abstract Archaeocyaths are calcareous, conical, Cambrian fossils with a long history of phylogenetic uncertainty and changing interpretations. The history of phylogenetic interpretation of archaeocyaths reveals five distinct schools of thought: the coelenterate school, the sponge school, the algae school, the Phylum Archaeocyatha school, and the Kingdom Archaeata school. Late nineteenth century and early twentieth century paleontologists worked within a paradigm of inexorably increasing… 
Prey fractionation in the Archaeocyatha and its implication for the ecology of the first animal reef systems
TLDR
A new method to estimate the limit on the upper size of plankton that could be consumed by an archaeocyath during life is outlined, showing that during the establishment of the first animal reef systems, prey partitioning was established as a way of reducing competition.
Poriferan paraphyly and its implications for Precambrian palaeobiology
TLDR
It is demonstrated, in accordance with previous molecular studies, that sponges are paraphyletic, and that calcisponge are more closely related to eumetazoans than they are to demosponges.
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,
The Ediacaran Biotas in Space and Time1

TLDR
It is concluded that the Ediacaran organisms show a diverse range of responses to various environmental parameters, and there is no basis for classifying them all as having a single body plan and mode of life.
Palaeontology of sponges - : a review
TLDR
The majority of palaeontologic studies are concerned with taxonomic aspects of fossil sponge faunas, but investigations of the microstructure of the calcareous skeleton, of phylogeny (especially of the early forms), and of various aspects of their ecology have produced important results.
1 Prey fractionation in the Archaeocyatha and its implication for the ecology of the first animal 1 reef systems 2 3 Running title : Prey fractionation in Archaeocyaths 4 5
20 Archaeocyaths are the most abundant sponges from the Cambrian period, forming the first animal 21 reef communities over 500 million years ago. The Archaeocyatha are index fossils for correlating
Cyathophycus and the origin of demosponges
TLDR
The evolutionary link between the classes is suggested to lie within the dictyospongioid and hazeliid lineages, and it is conceptually much easier to derive the demosponges from the hexactinellids, rather than vice versa.
Following the logic behind biological interpretations of the Ediacaran biotas
Abstract For almost 150 years, megascopic structures in siliciclastic sequences of terminal Precambrian age have been frustratingly difficult to characterize and classify. As with all other areas of
Photosymbiosis in Past and Present Reefs
TLDR
The hypothesis that photosymbiosis best explains both the successes and failures of reefs through geologic time is developed and evidence is reviewed that suggests photosyMBiosis in reef organisms played significant roles throughGeologic time in both the evolution and extinction of organisms and the reefs they constructed.

TLDR
Differences in flow pattern between the porous- and aporous-septate models suggest a hitherto unknown function for septa, which may be a mechanism by which outer-wall leakage is avoided later in life.
