It has long been appreciated that the fossil record is strongly biased towards groups with mineralized skeletons. If most or all animal phyla originated in the Precambrian [1], then many softbodied phyla must have long histories unrepresented in the fossil record. Among these are the Entoprocta, a small phylum of aquatic metazoans. The only supposed fossil entoproct is the Cambrian genus Dinomischus [2-4] . However, body size in Dinomischus is at least an order of magnitude greater than that of…

Tentaculate Fossils from the Cambrian of Canada (British Columbia) and China (Yunnan) Interpreted as Primitive Deuterostomes
TLDR
The evidence is suggested that the evidence is more consistent with the ambulacraria being primitive deuterostomes, with specific comparisons being made to the pterobranch hemichordates and pre-radial echinoderms.
A sclerite-bearing stem group entoproct from the early Cambrian and its implications
The Lophotrochozoa includes disparate tentacle-bearing sessile protostome animals, which apparently appeared in the Cambrian explosion, but lack an uncontested fossil record. Here we describe…
THE OLDEST-KNOWN METAZOAN PARASITE?
TLDR
The example reported herepredates the oldest of these previous records by approximately 35to 40 million years, and demonstrates that symbiosis involvingcomplex adaptations were already established soon after the ‘explosive’ radiation of marine metazoans in the early Cambrian.
Birth and early evolution of metazoans
A soft-bodied lophophorate from the Silurian of England
TLDR
A small fossil lophophorate, attached to a brachiopod dorsal valve, is described from the Silurian Herefordshire Lagerstätte of England, and might also represent a significant element of the Palaeozoic lphophorate fauna.
The Cambrian Conundrum: Early Divergence and Later Ecological Success in the Early History of Animals
TLDR
A compilation of the patterns of fossil and molecular diversification, comparative developmental data, and information on ecological feeding strategies indicate that the major animal clades diverged many tens of millions of years before their first appearance in the fossil record.
The stalked filter feeder Siphusauctum lloydguntheri n. sp. from the middle Cambrian (Series 3, Stage 5) Spence Shale of Utah: its biological affinities and taphonomy
TLDR
A new species of enigmatic stalked filter feeder, Siphusauctum lloydguntheri, from the middle Cambrian (Series 3, Stage 5) Antimony Canyon locality of the Spence Shale of northern Utah is described.

Causes and consequences of the Cambrian explosion

The adult and larval morphology and life history of the entoproct Barentsia gracilis (M. Sars, 1835)
TLDR
The feeding behavior of the adult is described and the larval feeding and rejection mechanism is reported for the first time and the first detailed morphology of an entoproct larva is presented and the striking similarity to the adult noted.

TLDR
It is proposed that illustrations for new descriptions of entoprocts should be standardized, and that the use of microphotos for this purpose be made obligatory, and a new approach proposed to the taxonomy of Kamptozoa consistent with phylogeny.

TLDR
A biological advantage in evolving of a heart-like organ to provide the stalk — which in colony type entoprocta is the budding center — with the nutrient “hemolymphe” is indicated.
Depositional history and palaeoecology of the Oxfordian/Kimmeridgian boundary beds at South Ferriby, South Humberside
SUMMARY The uppermost Ampthill Clay and lowermost Kimmeridge Clay are well exposed in a pit at South Ferriby. This provides an exceptional record of depositional conditions across the…
Cuticular pores and spines in the Pedicellinidae and Barentsiidae (Entoprocta), their relationship, ultrastructure, and suggested function, and their phylogenetic evidence
TLDR
The cuticular pores and hollow spines often described as species-characteristic integumental differentiations in numerous Entoprocta are shown to be comparable and, by intermediate stages, linked structures, the development of which is governed by environmental conditions.
Studies on the regeneration of an entoproct, Barentsia discreta
TLDR
The double calyx seems to result from calyx regeneration effected without loss of the original calyx, and in every regenerate, the original oral-anal axis is retained.

TLDR
A much more complete description, numerous measurements and more detailed illustrations of Barentsia laxa than have been previously available have been presented to aid those who wish to make a further study of B. laxa embryology.
