The evolutionary emergence of animals is one of the most significant episodes in the history
of life, but its timing remains poorly constrained. Molecular clocks estimate that animals …

Assemblages of mineralized skeletal fossils are described from limestone rocks of the lower
Cambrian Nemakit-Daldyn, Medvezhya, Kugda-Yuryakh, Manykay, and lower Emyaksin …

The dynamics of how metazoan phyla appeared and evolved–known as the Cambrian
Explosion–remains elusive. We present a quantitative analysis of the temporal distribution …

Abstract Exceptionally preserved 'Burgess Shale‐type'fossil assemblages from the
Cambrian of Laurentia, South China and Australia record a diverse array of non …

Abstract The Yangtze platform of South China offers evidence within its Ediacaran–
Cambrian geological record of the Cambrian explosion and diversification events in …

The origin of Bryozoa has long been an intriguing mystery, largely due to the dearth of
unambiguous bryozoan fossils within Cambrian strata. The earliest bryozoan thus far …

Hyoliths were among the earliest biomineralizing metazoans in Palaeozoic marine
environments. They have been known for two centuries and widely assigned to …

The principal animal lineages (phyla) diverged in the Cambrian, but most diversity at lower
taxonomic ranks arose more gradually over the subsequent 500 Myr. Annelid worms seem …

Orthrozanclus is a shell-bearing, sclerite covered Cambrian organism of uncertain
taxonomic affinity, seemingly representing an intermediate between its fellow problematica …

Exceptionally preserved fossils, such as those from Cambrian Burgess Shale-type fossil-
Lagerstätten are critical because of their unique contributions to knowledge of the …
