The Silurian-Devonian interval is an essential period in Earth history for witnessing the rise of sarcopterygian fishes and terrestrial vascular plants. In addition to its implication in global stratigraphic correlation, the precise location of the Silurian-Devonian boundary (SDB) in East Yunnan closely relates to the minimal and maximal estimated dates for the lungfish-tetrapod split. Several geochemical indicators including the values and curves of δ13Corg, δ13Ccarb and TOC are obtained from… 

A new dipnoan genus from the Middle Devonian of Huize, Yunnan, China

TLDR
As the ninth Devonian lungfish genus from China, the new taxon displays a novel schema of lungfish dentition and increases the diversity of early lungfishes.

A New Family of Galeaspids (Jawless Stem‐Gnathostomata) from the Early Silurian of Chongqing, Southwestern China

TLDR
As the first fish described from the Llandovery Huixingshao Formation in Chongqing, Yongdongaspis provides new fossil evidence for the subdivision and correlation of the Upper Red Beds in South China.

Semantic segmentation of vertebrate microfossils from computed tomography data using a deep learning approach

TLDR
A deep-learning-based (DL-based) semantic segmentation method for vertebrate microfossils from CT data is proposed, which shows that the intersection over union (IoU) performance metric arrived at least 94.39 %, meeting the semantic segmentations requirements of paleontologists.
