Fossil age data and molecular sequences are increasingly combined to establish a
timescale for the Tree of Life. Arthropods, as the most species-rich and morphologically …

In order to understand relationships between living and fossil groups of spinicaudatan clam
shrimp, it is important to review historical and contemporary attempts at evaluating the …

Abstract The Triassic Period was the setting for the origin and early diversification of
Mesozoic ecosystems after the end-Permian mass extinction. The study of the Triassic is …

Conchostracans (Crustacea: Branchiopoda) are one of the best prospective invertebrate
groups for the biostratigraphy of continental deposits, especially in the otherwise fossil-poor …

A well-preserved spinicaudatan species, Yanjiestheria huajiyingensis sp. nov., is here
described from the Huajiying Formation in northern Hebei, northern China. The species is …

Clam shrimp (the paraphyletic assemblage of spinicaudatans, laevicaudatans, cyclestherids
