  pages={2383 - 2386}
We describe a Proterozoic, fully biomineralized metazoan from the Omkyk Member (∼549 million years before the present) of the northern Nama Group, Namibia. Namapoikia rietoogensis gen. et sp. nov. is up to 1 meter in diameter and bears a complex and robust biomineralized skeleton; it probably represents a cnidarian or poriferan. Namapoikia encrusts perpendicular to the walls of vertical synsedimentary fissures in microbial reefs. This finding implies that large, modular metazoans with… Expand
Skeletogenesis in problematic Late Proterozoic Lower Metazoa
This paper discusses supporting structures in problematic Late Precambrian Lower Metazoa, sponge and cnidarian affinity. These structure include aggregates of agglutinated mineral particles;Expand
The Deep-Sea Chemoautotroph Microbial World as Experienced by the Mediterranean Metazoans Through Time
This paper is focused upon the Miocene-to-Recent deep-sea chemosynthetic ecosystems of the Mediterranean basin with emphasis on their metazoan associates. The life ingredients of this story areExpand
Unanswered Questions in the Evolution of Biomineralisation
Organisms have been building hard parts since the Late Precambrian. In fact representatives of all Kingdoms are able to biomineralise in the form of granules, plates, tubes, shells , bones or teeth.Expand
The Precambrian-Cambrian transition saw the burgeoning of diverse skeletal organisms ("small shelly fossils"), represented in the fossil record by spicules, tubes, tests, conchs, shells, and aExpand
Metazoan calcium carbonate biomineralizations: macroevolutionary trends - challenges for the coming decade.
Calcium carbonate-based biominerals, also referred as biocalcifications, are the most abundant biogenic mineralized products at the surface of the Earth. In this paper, we summarize general conceptsExpand
Extensive metazoan reefs from the Ediacaran Nama Group, Namibia: the rise of benthic suspension feeding.
New, ecologically complex reef types from the Ediacaran Nama Group, Namibia, dated at ~548 million years ago, are described, showing an abundance of inferred suspension feeders with biomineralised skeletons indicates the efficient exploitation of new resources, more active carbon removal with a strengthened energy flow between planktic and benthic realms, and the rise of biological control overbenthic carbonate production.

Paleoecology of the earliest skeletal metazoan communities: Implications for early biomineralization
Observations support the view that skeletonization was promoted by the rise of substrate competitors and bilaterian predators, in predominately carbonate platform and reef environments. Expand
Dynamic redox conditions control late Ediacaran metazoan ecosystems in the Nama Group, Namibia
The first appearance of skeletal metazoans in the late Ediacaran (~550 million years ago; Ma) has been linked to the widespread development of oxygenated oceanic conditions, but a precise spatial andExpand
Introduction to thematic set of papers on the Ediacaran–Cambrian palaeoecology, sedimentology and stratigraphy of Namibia
The Neoproterozoic was a time of profound biological and geological change. After a long time of verymodest changes in the flora and fauna, the Ediacaran period finally brought forward the firstExpand
Intraspecific variation in an Ediacaran skeletal metazoan: Namacalathus from the Nama Group, Namibia
Namacalathus, which forms a component of these communities in the Nama Group, was a generalist that adapted to various palaeoecological habitats within a heterogeneous ecosystem landscape where favourable conditions persisted, and was also able to opportunistically colonise transiently hospitable environments.

ABsTRAC--New fossils from the Neoproterozoic Ediacara fauna of South Australia are interpreted as the oldest known hexactinellid sponges. They occur within the Ediacara Member of the RawnsleyExpand
Ediacarian sponge spicule clusters from southwestern Mongolia and the origins of the Cambrian fauna
Carbon and strontium isotopic data are used to show that the earliest sponge spicule clusters and associated phosphatic sediments (with Anabarites ) from southwestern Mongolia are of Ediacarian age.Expand
Biostratigraphic and Geochronologic Constraints on Early Animal Evolution
Two distinct evolutionary pulses, represented by the Vendian Ediacaran fauna and Cambrian small shelly faunas, are generally thought to characterize the emergence of macroscopic animals at the end ofExpand
Complex trace fossils from the terminal Proterozoic of Namibia
We document for the first time the occurrence of the complex trace fossil Treptichnus from the terminal Proterozoic Nama Group, Namibia. These traces differ in detail from the Cambrian index fossilExpand

Namacalathus-Cloudina assemblage in Neoproterozoic Miette Group (Byng Formation), British Columbia: Canada's oldest shelly fossils
The uppermost part of the Miette Group (Windermere Supergroup) in eastern British Columbia has yielded shelly macrofossils in cliff-forming biostromal carbonates (Byng Formation). The biostromes areExpand
Digital reconstruction of calcified early metazoans, terminal Proterozoic Nama Group, Namibia
Abstract A method is presented for the digital reconstruction of weakly calcified fossils within the Nama Group, Namibia. These recently described fossils (Grotzinger et al. 2000) are preserved asExpand
The youngest Ediacaran fossils from southern Africa.
The discovery of fossils of the Ediacara biota near the top of the Spitzkopf Member at farm Swanpunt extends the known range of these remains in Namibia more than 600 m to near the sub-Cambrian unconformity and provides support for the concept of the "Vendobionta" as a late Neoproterozoic group of mainly multifoliate organisms with a distinctive quilted segmentation.
