TL;DR: A recently discovered craniate-like chordate, Haikouella lanceolata, is described from 305 fossil specimens inHaikou near Kunming, indicating that this 530 million-year-old (Myr) fish-like animal probably represents a very early craniatesate- like chordate that lived near the beginning of the Cambrian period during the main burst ofThe Cambrian explosion.

TL;DR: Although these discoveries reveal unexpected Pennsylvanian eumetabolan diversity, the lineage radiated more successfully only after the mass extinctions at the end of the Permian period, giving rise to the familiar crown groups of their respective clades.

TL;DR: Several Palaeozoic and early Mesozoic fossils that were ascribed to Paraneoptera are reinterpreted, and the attribution of several to this superorder is confirmed as well as possible attribution of Zygopsocidae (Zygopsocus permianus Tillyard, 1935) as oldest Psocodea.

TL;DR: This paper reported a variety of marine animals symbiotic with or adhere to Burmese amber or the amber deposits, including crinoid columns, corals and oysters, and suggested that it is plausible to generally refer to the age of Burmies amber as mid-Cretaceous, and a precise age requires further biostratigraphic and chronological studies.

TL;DR: Based on new, more complete “Cheungkongella” specimens that show branching tentacles, this form may be a lophophorate, and in any case is not a tunicate.
