  • A Stem Group Echinoderm from the Basal Cambrian of China and the Origins of Ambulacraria
    ARTICLE https://doi.org/10.1038/s41467-019-09059-3 OPEN A stem group echinoderm from the basal Cambrian of China and the origins of Ambulacraria Timothy P. Topper 1,2,3, Junfeng Guo4, Sébastien Clausen 5, Christian B. Skovsted2 & Zhifei Zhang1 Deuterostomes are a morphologically disparate clade, encompassing the chordates (including vertebrates), the hemichordates (the vermiform enteropneusts and the colonial tube-dwelling pterobranchs) and the echinoderms (including starfish). Although deuter- 1234567890():,; ostomes are considered monophyletic, the inter-relationships between the three clades remain highly contentious. Here we report, Yanjiahella biscarpa, a bilaterally symmetrical, solitary metazoan from the early Cambrian (Fortunian) of China with a characteristic echinoderm-like plated theca, a muscular stalk reminiscent of the hemichordates and a pair of feeding appendages. Our phylogenetic analysis indicates that Y. biscarpa is a stem- echinoderm and not only is this species the oldest and most basal echinoderm, but it also predates all known hemichordates, and is among the earliest deuterostomes. This taxon confirms that echinoderms acquired plating before pentaradial symmetry and that their history is rooted in bilateral forms. Yanjiahella biscarpa shares morphological similarities with both enteropneusts and echinoderms, indicating that the enteropneust body plan is ancestral within hemichordates. 1 Shaanxi Key Laboratory of Early Life and Environments, State Key Laboratory of Continental Dynamics and Department of Geology, Northwest University, 710069 Xi’an, China. 2 Department of Palaeobiology, Swedish Museum of Natural History, Box 50007104 05, Stockholm, Sweden. 3 Department of Earth Sciences, Durham University, Durham DH1 3LE, UK. 4 School of Earth Science and Resources, Key Laboratory for the study of Focused Magmatism and Giant Ore Deposits, MLR, Chang’an University, 710054 Xi’an, China.

  • The Early History of the Metazoa—A Paleontologist's Viewpoint
    ISSN 20790864, Biology Bulletin Reviews, 2015, Vol. 5, No. 5, pp. 415–461. © Pleiades Publishing, Ltd., 2015. Original Russian Text © A.Yu. Zhuravlev, 2014, published in Zhurnal Obshchei Biologii, 2014, Vol. 75, No. 6, pp. 411–465. The Early History of the Metazoa—a Paleontologist’s Viewpoint A. Yu. Zhuravlev Geological Institute, Russian Academy of Sciences, per. Pyzhevsky 7, Moscow, 7119017 Russia email: [email protected] Received January 21, 2014 Abstract—Successful molecular biology, which led to the revision of fundamental views on the relationships and evolutionary pathways of major groups (“phyla”) of multicellular animals, has been much more appre ciated by paleontologists than by zoologists. This is not surprising, because it is the fossil record that provides evidence for the hypotheses of molecular biology. The fossil record suggests that the different “phyla” now united in the Ecdysozoa, which comprises arthropods, onychophorans, tardigrades, priapulids, and nemato morphs, include a number of transitional forms that became extinct in the early Palaeozoic. The morphology of these organisms agrees entirely with that of the hypothetical ancestral forms reconstructed based on onto genetic studies. No intermediates, even tentative ones, between arthropods and annelids are found in the fos sil record. The study of the earliest Deuterostomia, the only branch of the Bilateria agreed on by all biological disciplines, gives insight into their early evolutionary history, suggesting the existence of motile bilaterally symmetrical forms at the dawn of chordates, hemichordates, and echinoderms. Interpretation of the early history of the Lophotrochozoa is even more difficult because, in contrast to other bilaterians, their oldest fos sils are preserved only as mineralized skeletons.

  • Cambrian Suspension-Feeding Tubicolous Hemichordates Karma Nanglu1* , Jean-Bernard Caron1,2, Simon Conway Morris3 and Christopher B
    Nanglu et al. BMC Biology (2016) 14:56 DOI 10.1186/s12915-016-0271-4 RESEARCH ARTICLE Open Access Cambrian suspension-feeding tubicolous hemichordates Karma Nanglu1* , Jean-Bernard Caron1,2, Simon Conway Morris3 and Christopher B. Cameron4 Abstract Background: The combination of a meager fossil record of vermiform enteropneusts and their disparity with the tubicolous pterobranchs renders early hemichordate evolution conjectural. The middle Cambrian Oesia disjuncta from the Burgess Shale has been compared to annelids, tunicates and chaetognaths, but on the basis of abundant new material is now identified as a primitive hemichordate. Results: Notable features include a facultative tubicolous habit, a posterior grasping structure and an extensive pharynx. These characters, along with the spirally arranged openings in the associated organic tube (previously assigned to the green alga Margaretia), confirm Oesia as a tiered suspension feeder. Conclusions: Increasing predation pressure was probably one of the main causes of a transition to the infauna. In crown group enteropneusts this was accompanied by a loss of the tube and reduction in gill bars, with a corresponding shift to deposit feeding. The posterior grasping structure may represent an ancestral precursor to the pterobranch stolon, so facilitating their colonial lifestyle. The focus on suspension feeding as a primary mode of life amongst the basal hemichordates adds further evidence to the hypothesis that suspension feeding is the ancestral state for the major clade Deuterostomia. Keywords: Enteropneusta, Hemichordata, Cambrian, Burgess Shale Background no modern counterpart [11]. The coeval Oesia disjuncta Hemichordates are central to our understanding of Walcott [12] has been compared to groups as diverse as deuterostome evolution.

  • A New Phyllopod Bed-Like Assemblage from the Burgess Shale of the Canadian Rockies
    ARTICLE Received 30 Dec 2013 | Accepted 7 Jan 2014 | Published 11 Feb 2014 DOI: 10.1038/ncomms4210 A new phyllopod bed-like assemblage from the Burgess Shale of the Canadian Rockies Jean-Bernard Caron1,2,3, Robert R. Gaines4,Ce´dric Aria1,2, M. Gabriela Ma´ngano5 & Michael Streng6 Burgess Shale-type fossil assemblages provide the best evidence of the ‘Cambrian explosion’. Here we report the discovery of an extraordinary new soft-bodied fauna from the Burgess Shale. Despite its proximity (ca. 40 km) to Walcott’s original locality, the Marble Canyon fossil assemblage is distinct, and offers new insights into the initial diversification of metazoans, their early morphological disparity, and the geographic ranges and longevity of many Cambrian taxa. The arthropod-dominated assemblage is remarkable for its high density and diversity of soft-bodied fossils, as well as for its large proportion of new species (22% of total diversity) and for the preservation of hitherto unreported anatomical features, including in the chordate Metaspriggina and the arthropod Mollisonia. The presence of the stem arthropods Misszhouia and Primicaris, previously known only from the early Cambrian of China, suggests that the palaeogeographic ranges and longevity of Burgess Shale taxa may be underestimated. 1 Department of Natural History-Palaeobiology, Royal Ontario Museum, 100 Queen’s Park, Toronto, Ontario, Canada M5S 2C6. 2 Department of Ecology and Evolutionary Biology, University of Toronto, 25 Willcocks Street, Toronto, Ontario, Canada M5S 3B2. 3 Department of Earth Sciences, University of Toronto, 25 Russell Street, Toronto, Ontario, Canada M5S 3B1. 4 Geology Department, Pomona College, 185 E.

  • Paleoecology of the Greater Phyllopod Bed Community, Burgess Shale ⁎ Jean-Bernard Caron , Donald A

Jackson Department of Ecology and Evolutionary Biology, University of Toronto, Toronto, Ontario, Canada M5S 3G5 Accepted 3 May 2007 Abstract To better understand temporal variations in species diversity and composition, ecological attributes, and environmental influences for the Middle Cambrian Burgess Shale community, we studied 50,900 fossil specimens belonging to 158 genera (mostly monospecific and non-biomineralized) representing 17 major taxonomic groups and 17 ecological categories. Fossils were collected in situ from within 26 massive siliciclastic mudstone beds of the Greater Phyllopod Bed (Walcott Quarry — Fossil Ridge). Previous taphonomic studies have demonstrated that each bed represents a single obrution event capturing a predominantly benthic community represented by census- and time-averaged assemblages, preserved within habitat. The Greater Phyllopod Bed (GPB) corresponds to an estimated depositional interval of 10 to 100 KA and thus potentially preserves community patterns in ecological and short-term evolutionary time. The community is dominated by epibenthic vagile deposit feeders and sessile suspension feeders, represented primarily by arthropods and sponges. Most species are characterized by low abundance and short stratigraphic range and usually do not recur through the section. It is likely that these are stenotopic forms (i.e., tolerant of a narrow range of habitats, or having a narrow geographical distribution). The few recurrent species tend to be numerically abundant and may represent eurytopic organisms (i.e., tolerant of a wide range of habitats, or having a wide geographical distribution).

  • Oesia – a New Tube Worm from Deep Cambrian Times
    Oesia – a new tube worm from deep Cambrian times The discovery of new fossils of an ancient seabed dwelling hemichordate called Oesia, reveals clues about their deep ancestry which is shared with humans. Oesia was found in 500 million year old, Mid Cambrian age, Burgess Shale strata of British Columbia in Canada. The fossil has been described by Professor Simon Conway Morris of the University of Cambridge and colleagues from the universities of Toronto and Montreal and the Royal Ontario Museum in Toronto in the latest issue of the journal BMC Biology. Image shows artist's impression of Oesia inside its tubular home. Credit: Marianne Collins Over the last 100 years the ancient strata of the Burgess Shale, exposed in the mountains and canyons of the Canadian Rockies, have been explored by generations of palaeontologists. In the 1960s the late Professor Harry Whittington (1916-2010), then Woodwardian Professor in the University of Cambridge, initiated a research programme on the extraordinarily well preserved fossils of the Burgess Shale, their biological relationships, ecology and evolution. Simon Conway Morris was part of Harry Whittington’s team from the 1970s and continues the research with colleagues in Cambridge and Canada. Despite the recovery of some 200,000 fossil specimens belonging to some 200 different species, the Burgess Shale biota continues to provide surprising new insights into seabed life in Mid Cambrian times, such as the surprising life habits of this new hemichordate Oesia. The new fossils were found in the Marble Canyon outcrop of the Burgess Shale in Kootenay National Park. Although Oesia fossils were first found over 100 years ago, their rarity held back reliable identification.
