The Swedish Cambrian ‘Orsten’‐type fossil sites have yielded diverse secondarily phosphatized three‐dimensionally preserved microfossils, mainly of arthropod affinities. Similar material has also been recorded from Canada, the UK, Poland, Siberia, China and Australia. Only one other non‐arthropod group, the Cycloneuralia, is commonly reported from any of these sites, leading to the general assumption that ‘Orsten’‐type preservation is largely restricted to animals with a chitin‐containing… 
Exceptionally well-preserved Orsten-type phosphatocopid crustaceans from the Cambrian of Poland
A three-dimensionally preserved specimen of a late growth stage of Cyclotron angelini from the Furongian strata of northern Poland is described, which possesses six pairs of appendages (2nd–7th pairs; antennula missing), much of setation, sternum with paragnath humps, and the trunk end with the putative anus.
Submarine metalliferous carbonate mounds in the Cambrian of the Baltoscandian Basin induced by vent networks and water column stratification
Two massive precipitation events of polymetallic ore deposits, encrusted by a mixture of authigenic carbonates, are documented from the Cambrian of the semi-enclosed Baltoscandian Basin. δ34S (‒9.33
Authigenic calcium carbonate precipitation in the “bathtub ring” around the anoxic Alum Shale Basin during the Furongian SPICE event (Baltic Basin, northern Poland)
ABSTRACT The precipitation of both biotic and abiotic calcium carbonate is of great importance in modern and ancient global biogeochemical cycles. In the present-day oceans, the widespread


Anomalous facies and ancient faeces in the latest middle Cambrian of Sweden
The middle Cambrian -Furongian transitional interval was a time of significant biotic and environmental changes. Strata of this age in Scania, southern Sweden, contain two interlayered biofacies, a

Permineralized Fossils from the Terminal Proterozoic Doushantuo Formation, South China
Permineralized fossils of the terminal Proterozoic (600–550 Ma) Doushantuo Formation, China, provide an unusually clear window on biological diversity just before the Ediacaran radiation. In the

Phosphatocopine ostracodes with preserved appendages from the Upper Cambrian of Sweden
The movement of food into the mouth was achieved by the endites of antennulae and antennae, a function transferred backwards to other appendages during the course of ostracode phylogeny and reflected in ontogenetic trends among Recent ostracodes.
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.
Formation and diagenesis of modern marine calcified cyanobacteria
The early diagenetic destruction of calcification filaments at Highborne Cay indicates that the absence of calcified cyanobacteria from periods of the Phanerozoic is likely to be caused by low preservation potential as well as inhibited formation.
