Burgess Shale fossils shed light on the agnostid problem
Autor: J. Moysiuk, Jean-Bernard Caron
Publikováno v: Proceedings of the Royal Society B: Biological Sciences. 286:20182314
Agnostids (agnostinids and eodiscinids) are a widespread and biostratigraphically important group of Cambro-Ordovician euarthropods whose evolutionary affinities have been highly controversial. Their dumbbell-shaped calcified tergum was traditionally

Hundred species of the genus Peronopsis Hawle et Corda, 1847
Autor: E. B. Naimark
Publikováno v: Paleontological Journal. 46:945-1057
The data on the genus Peronopsis, including 116 species and subspecies, that is, at least half of Middle Cambrian agnostians, are completely revised. The revision is based on the order of the formation of pygidial characters in ontogeny. A convenient

Guzhangian (mid Cambrian) trilobites from siliceous concretions of the Valtorres Formation, Iberian Chains, NE Spain
Autor: Samuel Zamora, Per Ahlberg, Daniel Vizcaïno, J. Javier Álvaro
Publikováno v: Geological Magazine. 150:123-142
In the carbonate-siliciclastic strata of West Gondwana (e.g. in the Montagne Noire, France), the aftermath of the mid Languedocian (mid Cambrian) regression is characterized by a late Languedocian major turnover of trilobite families and a Furongian
