Data from: Cretophengodidae, a new Cretaceous beetle family sheds light on the evolution of bioluminescence

Chenyang Cai
Bioluminescent beetles of the superfamily Elateroidea (fireflies, fire beetles, glow-worms) are the most speciose group of terrestrial light-producing animals. The evolution of bioluminescence in elateroids is associated with unusual morphological modifications, such as soft-bodiedness and neoteny, but the fragmentary nature of the fossil record discloses little about the origin of these adaptations. We report the discovery of a new bioluminescent elateroid beetle family from the mid-Cretaceous of northern Myanmar (ca. 99 Ma), Cretophengodidae fam. nov....

Verifiability of genus-level classification under quantification and parsimony theories: a case study of follicucullid radiolarians

Yifan Xiao, Noritoshi Suzuki, Weihong He, Michael Benton, Tinglu Yang & Chenyang Cai
The classical taxonomy of fossil invertebrates is based on subjective judgments of morphology, which can cause confusion since there are no codified standards for the classification of genera. Here, we explore the validity of the genus taxonomy of 75 species and morphospecies of the Follicucullidae, a Late Paleozoic family of radiolarians, using a new method, Hayashi’s quantification theory II (HQT-II), a general multivariate statistical method for categorical datasets relevant to discriminant analysis. We identify a...

Data from: The Collins’ monster, a spinous suspension-feeding lobopodian from the Cambrian Burgess Shale of British Columbia

Jean-Bernard Caron & Cédric Aria
Lobopodians, a paraphyletic group of Palaeozoic vermiform animals bearing metameric appendages, are key to the origin of extant panarthropods. First discovered in 1983 on Mount Stephen (Yoho National Park, British Columbia), the Cambrian (Wuliuan) Burgess Shale lobopodian nicknamed “Collins’ monster” is formally described as Collinsovermis monstruosus gen. et sp. nov. A formal systematic revision of the poorly known lobopodian Acinocricus stichus from Utah is also provided. The body of Collinsovermis is plump and compact, lacking...

Detailed description of the new genus and speceis, Cretophengodes azari Li, Kundrata, Tihelka and Cai sp. nov.

Data from: Middle Permian fusulines from the Thitsipin Formation of Shan State, Myanmar and their palaeobiogeographical and palaeogeographical implications

Yichun Zhang, Kyipyar Aung, Shuzhong Shen, Hua Zhang, Than Zaw, Lin Ding, Fulong Cai & Kyain Sein
Fusuline faunas including 29 species belonging to 19 genera/subgenera are described from the Thitsipin Formation in eight sections/localities on the Shan Plateau in eastern Myanmar. These fusulines broadly indicate a Midian (middle Permian, Guadalupian) age. The lower diversity and the presence of some genera, such as Monodiexodina and Eopolydiexodina, suggest that the Sibumasu Block belonged to the palaeobiogeographic Cimmerian Province during the Midian. Furthermore, quantitative cluster analyses of middle Permian fusulines from the Shan Plateau...

Data from: Evolution of the conodont Diplognathodus ellesmerensis from D. benderi sp. nov. at the Bashkirian-Moscovian (Lower-Middle Pennsylvanian) boundary in South China

Keyi Hu, Nicholas Hogancamp, Lance Lambert, Yuping Qi & Jitao Chen
Conodont assemblages from the Bashkirian-Moscovian boundary interval in the Naqing section, South China have been studied in detail. A landmark-based geometric morphometric analysis to study the evolution of Diplognathodus ellesmerensis is presented. This analysis helped recognize a distinct new species, D. benderi sp. nov., which represents the direct evolutionary ancestor of D. ellesmerensis. The potential of using the First Appearance Datum (FAD) of D. ellesmerensis as the Bashkirian-Moscovian boundary marker is re-evaluated via biostratigraphic correlations...

Burmorussidae, a new family of parasitic wasps (Insecta: Hymenoptera) from mid-Cretaceous Burmese amber

Zhang Qi, Kopylov Dmitry, Rasnitsyn Alexandr, Zheng Yan & Zhang Haichun
A new genus and species, Burmorussus mirabilis, is described based on two specimens from the mid-Cretaceous Burmese amber, and considered to be a specialized parasitic wasp of wood-living hosts. The new taxon is characterized by an orussid-like ocellar crown, big eyes, antennae attached well above the clypeus, and antennal grooves or ventral transverse frontal carinae absent. Additionally, all legs carry a prominent lanceolate lobe on the 3rd tarsomere. A similar structure is found, but organized...

Data from: First record of organic-walled microfossils from the Tonian Shiwangzhuang Formation of the Tumen Group in western Shandong, North China

Chun-Mei Han, Lei Chen, Guang-Jin Li, Ke Pang, Wei Wang, Guang-Zhao Zhou, Le Yang, Wei-Guo Lyu, Kai Wang, Zhen-Hua Zhong, Cheng-Xi Wu & Feng-Jie Yang
Organic-walled microfossils offer an important window onto the biospheric evolution in pre-Cryogenian and provide biostratigraphic implications for many Proterozoic fossiliferous sequences which are poorly age constrained for the lack of reliable radiometric date. Recently, macroscopic carbonaceous compression fossils have been reported for the first time from the Tonian Shiwangzhuang Formation of the Tumen Group in western Shandong, North China. However, organic-walled microfossils have never been discovered in the Shiwangzhuang Formation before. To improve our knowledge...
