Abstract Early faunas with Watsonella crosbyi with or without Aldanella spp. have been equated with the Siberian Tommotian Stage (uppermost Terreneuvian) and used to define a proposed Cambrian Stage 2 base. Much earlier Terreneuvian occurrences are now shown by recovery of these micromolluscs below the I’ carbon excursion in the Siberian ‘Nemakit-Daldynian’ Stage and comparable δ13C excursions in the middle Meishucunian (China) and middle Chapel Island Formation (Avalonia). This δ13C excursion… Expand
The Precambrian–Phanerozoic and Ediacaran–Cambrian boundaries: a historical approach to a dilemma
Abstract The Cambrian was originally defined as a rock interval with a trilobite-dominated fauna that overlay a presumed biologically barren Precambrian epoch. Work to formally define the CambrianExpand
Global correlation of the early Cambrian of South Australia: Shelly fauna of the Dailyatia odyssei Zone
A lack of well resolved biostratigraphic data has prevented robust regional and global correlation of lower Cambrian successions from South Australia. A new early Cambrian biostratigraphy, based onExpand
Environmental setting of the Cambrian Terreneuvian rocks from the southwestern Yangtze Platform, South China
Abstract Terreneuvian strata from the western Yangtze Platform host diverse assemblages of small shelly fossils (SSFs), which are key for understanding the Cambrian Bioradiation Event and have beenExpand
Cambrian small skeletal fossil and carbon isotope records of the southern Huangling Anticline, Hubei (China) and implications for chemostratigraphy of the Yangtze Platform
Abstract Rich small skeletal fossil assemblages are described from the Yanjiahe Formation and Tianzhushan Member of southern Huangling Anticline. The Anabarites trisulcatus– Protohertzina anabaricaExpand
Watsonella crosbyi from the lower Cambrian (Terreneuvian, Stage 2) Normanville Group in South Australia
Abstract Correlation of lower Cambrian strata is often confounded by provincialism of key fauna. The widespread occurrence of the micromollusc Watsonella crosbyi Grabau, 1900 is therefore anExpand
Early Cambrian chronostratigraphy and geochronology of South Australia
Abstract The most successful chronostratigraphic correlation methods enlist multiple proxies such as biostratigraphy and chemostratigraphy to constrain the timing of globally important bio- andExpand
An integrated stratinomic model for the genesis and concentration of “small shelly fossil”-style phosphatic microsteinkerns in not-so-exceptional conditions
Abstract Carbonate fluorapatite-filled millimeter-scale microsteinkerns are a key element of the “Small Shelly Fossil” (SSF) fauna generally associated with the late Proterozoic–Cambrian. TheExpand
Terreneuvian bio- and chemostratigraphy of the South Sichuan Region (South China)
Classical sections, such as the Maidiping and Daqiao Mine sections of South Sichuan (China), expose early Cambrian deposits that are crucial for understanding the biological and environmentalExpand
Integrated stratigraphic, geochemical, and paleontological late Ediacaran to early Cambrian records from southwestern Mongolia: Comment
Global correlation of sedimentary rock successions requires an integrated approach that uses all fossil-based and alternative (lithostratigraphic, geochemical, paleomagnetic, geochronologic, sequenceExpand
Comment on “Terreneuvian small shelly faunas of east Yunnan (South China) and their biostratigraphic implications” by B. Yang et al. [Palaeogeography, Palaeoclimatology, Palaeoecology 398 (2014) 28–58]
The recent article by Yang et al. (2014 provides a very useful summary of the litho- and biostratigraphy of the sub-trilobitic lower Cambrian on the tropical shelf of South China. Our concern withExpand


Precambrian-Cambrian boundary global stratotype ratified and a new perspective of Cambrian time
The Precambrian-Cambrian boundary global stratotype is the base of the Phycodes pedum Zone at Fortune Head, southeastern Newfoundland. The initial, two-stage radiation of the Phanerozoic fauna (theExpand
Precambrian/Cambrian boundary problem: Carbon isotope correlations for Vendian and Tommotian time between Siberia and Morocco
At least three distinctive cycles are preserved in the carbon-isotope patterns for the Vendian/Tommotian interval of the Siberian platform and the Anti-Atlas Mountains of Morocco. In Siberia, anExpand
How old is the Tommotian
Shelly faunas and phytoplankton from Lower Cambrian (Tommotian) strata within and outside the type area in Siberia indicate that the Tommotian Stage is younger than previously believed. DepositsExpand
Chronostratigraphic and palaeogeographic significance of an early Cambrian microfauna from the Heraultia Limestone, northern Montagne Noire, France
Abundant and diverse Small Shelly Fossils (SSFs) have been reported in Northern Montagne Noire (Southern France) since the last 20th century from early Cambrian phosphatic carbonates called HeraultiaExpand
Cambrian Evolutionary Radiation: Context, correlation, and chronostratigraphy—Overcoming deficiencies of the first appearance datum (FAD) concept
Abstract Use of the first appearance datum (FAD) of a fossil to define a global chronostratigraphic unit's base can lead to intractable correlation and stability problems. FADs are diachronous—theyExpand
Integrated chemo- and biostratigraphic calibration of early animal evolution; Neoproterozoic-Early Cambrian of Southwest Mongolia
Five overlapping sections from the thick Neoproterozoic to early Cambrian sediments of western Mongolia were analysed to yield a remarkable carbon-isotope, strontium-isotope and small shellyfossilExpand

Biostratigraphy of the Vendian-Cambrian beds and the Lower Cambrian boundary in Siberia
General agreement exists that the position of the base of the Cambrian (Precambrian–Cambrian boundary) should coincide with a biostratigraphic marker that can be widely traced and is linked to theExpand
Carbon isotope stratigraphy and the problem of a pre-Tommotian Stage in Siberia

Integrated chronostratigraphy of Proterozoic-Cambrian boundary beds in the western Anabar region, northern Siberia.
Carbonate-rich sedimentary rocks of the western Anabar region, northern Siberia, preserve an exceptional record of evolutionary and biogeochemical events near the Proterozoic/Cambrian boundary, suggesting that this interval lasted approximately three to six million years, during which essentially all 'basal Tommotian' small shelly fossils evolved.
