Of the 21 or so generally accepted animal phyla, only one, the Ctenophora, has no fossil record1. The Phylum Ctenophora or comb jellies, are typically globular, swimming marine organisms, widely distributed in today's oceans. They are small, delicate, mostly planktonic animals of a gelatinous nature2 that were first considered to be coelenterates but later were recognized as a distinct group of phylum rank. We have now discovered the pyritized fossil remains of a small, globular, soft-bodied… Expand
A Fresh Look at Dickinsonia:Removing It from Vendobionta
TLDR
This research is not only removing Dickinsonia from Vendobionta, but also bringing the fossil record of ctenophores forward to 20 million years before the Cambrian “explosion”. Expand
Middle Cambrian ctenophores from the Stephen Formation, British Columbia, Canada
TLDR
The Ctenophora are a marine phylum of gelatinous swimmers and crawlers, with a minimal fossilization potential, but they probably evolved very early in the metazoan radiations, perhaps from an animal with an anterio-posterior axis and a ciliated surface. Expand
Eoandromeda and the origin of Ctenophora
TLDR
The Ediacaran fossil Eoandromeda octobrachiata had a high conical body with eight arms in helicospiral arrangement along the flanks, and was interpreted as an early stem‐group ctenophore, characterized by the synapomorphies ctenes, comb rows, and octoradial symmetry but lacking crown‐group synapomorphicies.

Raman spectra of a Lower Cambrian ctenophore embryo from southwestern Shaanxi, China
TLDR
The oldest ctenophore and the only embryonic comb jelly known from the fossil record, this exceptionally well preserved specimen provides important clues about the early evolution of the phylum Ctenophora and of metazoans in general. Expand
A molecular phylogenetic framework for the phylum Ctenophora using 18S rRNA genes.
TLDR
The first molecular phylogenetic analysis of the phylum Ctenophora, by use of 18S ribosomal RNA sequences from most of the major taxa, suggests that the ctenophores form a distinct monophyletic group that is most closely related to the cnidarians. Expand
A small coleoid cephalopod with soft parts from the lower Devonian discovered using radiography
During the past 50 years, X-ray examinations have greatly increased our knowledge of fossils. Modern radiographic methods, X-ray tubes with fine focal spots, high-resolution films and optimalExpand
BASAL METAZOANS
Basal metazoans comprise the four non-bilaterian animal phyla Porifera (sponges), Cnidaria (anthozoans and jellyfishes), Placozoa (Trichoplax) and Ctenophora (comb jellies). The phylogenetic positionExpand
The hidden biology of sponges and ctenophores.
TLDR
Key details of this new model hinge on a better understanding of the Porifera and Ctenophora, which have each been hypothesized to be sister to all other animals, but are poorly studied and often misrepresented. Expand
Revisiting the phylogeny of phylum Ctenophora: a molecular perspective
TLDR
A meta-analysis of previously published data of the phylum Ctenophora shows improvement in the orders placement and presenting new interesting relationship between the paraphyletic order Cydippida and the other ctenophores. Expand
Emergence, biodiversification and extinction of the chitinozoan group
Abstract Chitinozoans are considered as reproductive bodies of marine invertebrates, called chitinozoophorans. These chitinozoophorans were most likely to have been small, pelagic or necto-pelagic,Expand
