Analysis of an expanded and revised dataset for Introverta shows that the precise position of Markuelia within this clade is dependent on the taxa included, and it is assigned to the scalidophoran total group to reflect uncertainty as to whether it is a stem-scalidophoral or astem-priapulid.

The oldest known priapulid‐like scalidophoran animal and its implications for the early evolution of cycloneuralians and ecdysozoans

A post‐embryonic scalidophoran fossil Eopriapulites sphinx is described, which represents the oldest known scalidphoran, from the early Cambrian Period (∼535 Ma) in South China, and shares a hexaradial pattern with the hexarADial arrangement of certain anatomical structures in kinorhynchs, loriciferans, nematoids, and Cambrian fossils such as Eolympia pedic

A new scalidophoran animal from the Cambrian Fortunian Stage of South China and its implications for the origin and early evolution of Kinorhyncha

New palaeoscolecid worms from the Furongian (upper Cambrian) of Hunan, South China: is Markuelia an embryonic palaeoscolecid?

The comparative anatomy of Markuelia and the co-occurring palaeoscolecids shows a number of distinctions, particularly in the structure of the tail; all similarities are scalidophoran or introvertan (cyclone- uralian) symplesiomorphies.

The disparity of priapulid, archaeopriapulid and palaeoscolecid worms in the light of new data

This study samples at the species level and includes numerous fossils and some extant forms described in the last fifteen years of Priapulids, among the first groups used to test hypotheses concerning the morphological disparity of Cambrian fossils relative to the extant fauna.

Introvert and pharynx of Mafangscolex, a Cambrian palaeoscolecid

New specimens of Mafangscolex from the Cambrian Stage 3 Xiaoshiba Lagerstätte in Kunming, China provide the first detailed account of a proboscis in Palaeoscoelcida sensu stricto, a core group of palaeos colecids characterized by having a tessellating scleritome of phosphatic plates and platelets.

Fossil priapulid Ottoia from the Kaili biota (Cambrian Series 3) of South China

The fossil priapulid Ottoia recovered from the Kaili biota, Cambrian Series 3 and Stage 5 of South China, is the first reported occurrence of the genus outside the Cambrian of Laurentia. A total of…

A New Exceptionally Preserved Cambrian Priapulid From The Chengjiang Lagerstätte

Inclusion of Eximipriapulus in the most recent character matrix for cladistic analysis of fossil and Recent priapulids resolves the new genus within the priapsulid crown group.

Internal anatomy of a fossilized embryonic stage of the Cambrian-Ordovician scalidophoran Markuelia

This is the first record of a fossilized nervous system in a scalidophoran, and the first instance in Orsten-style preservation, opening the potential for further such records within this widespread mode of high-fidelity three-dimensional preservation.

Problematic Porifera from the Lower Cambrian of Western Mongolia

A Possible Larval Roundworm from the Cambrian 'Orsten' and Its Bearing on the Phylogeny of Cycloneuralia

Shergoldana australiensis is presented here as possibly the first record of a free-living immature cycloneuralian from the Cambrian, even if it remains uncertain whether it has closer affinities to the one or other in-group.

The Nemertodermatida are basal bilaterians and not members of the Platyhelminthes

The results imply that the last common ancestor of bilaterian metazoans was a small, benthic, direct developer without segments, coelomic cavities, nephrida or a true brain.

The anatomy, affinity, and phylogenetic significance of Markuelia

The available evidence supports stem‐Scalidophora affinity, leading to the conclusion that scalidophorans, cyclonerualians, and ecdysozoans are primitive direct developers, and the likelihood that scidalophoran are primitively metameric.

Are palaeoscolecids ancestral ecdysozoans?

It is concluded that previous interpretations in which palaeoscolecids occupy a deeper position in the ecdysozoan tree lack particular morphological support and rely instead on a paucity of preserved characters, bears out a more general point that fossil taxa may appear plesiomorphic merely because they preserve only plesiomorphies, rather than the mélange of primitive and derived characters anticipated of organisms properly allocated to a position deep within animal phylogeny.

ONTOGENY AND TAPHONOMY: AN EXPERIMENTAL TAPHONOMY STUDY OF THE DEVELOPMENT OF THE BRINE SHRIMP ARTEMIA SALINA

The experimental results provide an explanatory model for the phenomenal abundance of putative diapause stage embryos, in the absence of postembryonic stages, as seen in the Ediacaran Doushantuo Formation of South China and the incompleteness of fossilized developmental sequences of embryos and larvae more generally.

Fossil embryos from the Middle and Late Cambrian period of Hunan, south China

Findings from Hunan, south China, corroborate, rather than contradict, the predictions of comparative embryology, providing direct historical support for the view that the life-history strategies of living taxa are representative of their stem lineages.

Eggs and embryos from the Cambrian.

A surprising new discovery of eggs with blastomeres and embryos with well-defined anatomy from the Cambrian of China and Siberia promises to extend the arena of debate on the nature of the earliest animals and when they originated.
