A new Late Devonian flora from Sonid Zuoqi, Inner Mongolia, northeastern China

Lingqi Bai, Pu Huang, Ning Yang, Wenxin Ju, Jianbo Liu, James Basinger, Honghe Xu & Jinzhuang Xue
The Silurian and Devonian plant fossil record is the basis for our understanding of the early evolution of land plants, yet our appreciation of early global phytogeographic evolution has been constrained by the focus of most studies on deposits from Europe, North America, and more recently South China. Devonian plants have been rarely recorded from northeastern China, and among previous records, few plants have been illustrated and formally described. In this article, megafossil plants representing...

Fossil evidence unveils an early Cambrian origin for Bryozoa

Zhiliang Zhang, Zhifei Zhang, Junye Ma, Paul Taylor, Luke Strotz, Sarah Jacquet, Christian Skovsted, Feiyang Chen, Jian Han & Glenn Brock
Bryozoans (ectoprocts or moss animals) are aquatic, dominantly sessile, filter-feeding lophophorates that construct an organic or calcareous modular colonial (clonal) exoskeleton. The presence of six major orders of bryozoans with advanced polymorphisms in lower Ordovician rocks strongly suggests a Cambrian origin for the largest and most diverse lophophorate phylum. However, a lack of convincing bryozoan fossils from the Cambrian has hampered resolution of the true origins and character assembly of earliest members of the group....

Data from: Mesozoic cupules and the origin of the angiosperm second integument

Gongle Shi, Fabiany Herrera, Patrick Herendeen, Elizabeth Clark & Peter Crane
The second integument of the angiosperm ovule is unique among seed plants, with developmental genetics that are distinct from those of the inner integument. Understanding how the second integument should be compared to structures in other seed plants is therefore crucial to resolving the long-standing question of the origins of angiosperms. Attention has focused on several extinct plants with recurved cupules that are reminiscent of the anatropous organization of the basic bitegmic ovules of angiosperms,...

Two datasets are included, one is Supplemental Data 1 cited in Liang et al. (2021) which contains detailed information of the occurrence data of previously published Lagenochitina esthonica. The other is Supplemental Data 2 cited...

Stratigraphic column of the Xiazhen Formation with the 18 stromatoporoid-bearing intervals

Juwan Jeon, Kun Liang, Jino Park, Stephen Kershaw & Yuandong Zhang
A diverse labechiid stromatoporoid assemblage that includes 16 species in 8 genera was found in the Upper Ordovician Xiazhen Formation (mid-late Katian) at Zhuzhai, Jiangxi Province of South China. The assemblage is characterized by a combination of: a) North China provincial species succeeding from their origination in the Darriwilian, including Pseudostylodictyon poshanense Ozaki, 1938, Labechia shanhsiensis Yabe and Sugiyama, 1930, Lb. variabilis Yabe and Sugiyama, 1930 and Labechiella regularis (Yabe and Sugiyama, 1930), and b)...

A ten-faced hexangulaconulariid from Cambrian Stage 2 of South China

Junfeng Guo, Jian Han, Heyo Van Iten, Zuchen Song, Yaqin Qiang, Wenzhe Wang, Zhifei Zhang & Guoxiang Li
Hexangulaconulariids (Cambrian stages 1‒2) are an extinct group of medusozoan polyps having a biradially symmetrical, fan-shaped periderm that is distinct from those of medusozoan polyps showing three-, four-, five-, or six-fold radial symmetry. Hexangulaconulariids exhibit substantial variation in gross morphology, including variation in the number of faces on each of the two major sides of the periderm. An intermediate taxon of hexangulaconulariids with ten faces (five on each major side) was expected. Here we describe...
