Redlichiid trilobite and small shelly fossils indicate strong ties of the North China craton
(NCC) to Gondwana during the early Cambrian, while recent discoveries of the …

The rapid appearance of major animal groups and complex marine communities during the
Cambrian explosion is recorded in large part in Burgess Shale-type lagerstätten. However …

Hurdiidae, a clade of Radiodonta that has attracted widespread attention in recent years, is
notable for their massive tripartite cephalic carapace and a wide variety of feeding habits …

The hurdiid radiodont Cambroraster is characterized by a prominent horseshoe-shaped
head carapace, which bears conspicuous posterolateral spinous processes and covers half …

The Paleozoic paleogeographic and tectonic evolution of the North China Block (NCB) are
poorly constrained due to the polarity ambiguity of its early Paleozoic paleopoles. Here we …

The diversification of the earliest echinoderms is “explosive” in both space and time.
Lepidocystids are the most basal blastozoans and their earliest known occurrences …

We report the extraordinarily preserved euarthropod Sidneyia minor sp. nov. from the
Cambrian Stage 3 Xiaoshiba Lagerstätte in Yunnan, South China. So far this is the earliest …

Evaporites are climate-sensitive sedimentary deposits with event stratigraphic,
paleogeographic, and paleoenvironmental significance. The Early Cambrian is …

The artiopodans, consisting of trilobites and their relatives, were a major euarthropod group
in the Paleozoic. Since the first discovery of Naraoia from the Chengjiang fauna, a significant …

Hyoliths are extinct enigmatic organisms of early lophotrochozoan affinity known globally
from the Palaeozoic Era and were especially diverse and abundant in the Cambrian Period …
