Malayacyclusgen. nov., the first Southeast Asian Cyclida (Crustacea) from the Early Carboniferous of Terengganu, Malaysia

Abstract

a new genus and species of the Cyclida (Crustacea), is reported from the Early Carboniferous (Visean) of Terengganu, eastern Peninsular Malaysia (East Malaya Block). The new genus possesses diagnostic features of both families Cyclidae and Americlidae. Plus, it develops the trifurcate posterior spines: a unique morphology that was not previously known for any cyclidan genera. Based on the possession of an anterior rostrum and optic notches, it is tentatively included in the Americlidae. This represents the first find of the Cyclida from Southeast Asia and the second from the Carboniferous of Asia (eastern Tethys).

Late Palaeozoic‐Mesozoic palaeontology and stratigraphy in China: A tribute to the achievements of Professor Zhuoting Liao

“…In this volume, seven papers describe various fossil groups from the Devonian (Q. Chen, Chen, Zhang, & Muir, 2021; H. Wang et al, 2021; Bai, Huang, Liu, & Xue, 2021; W. Guo et al, 2021; Qiao et al, 2021; Song et al, 2021; Zong, Becker, & Ma, 2021). Six papers concern palaeontology and stratigraphy from the Carboniferous (Yao et al, 2021; Z. Guo, Chen, Harper, & Huang, 2021; Tang et al, 2021; Shi et al, 2021; Mao et al, 2021; X. Huang et al, 2021). Six papers report various fossil groups (bivalves, corals, and plants) (F. Chen, Xue, Yan, & Meng, 2021; Wan, Yang, Wang, Liu, & Wang, 2021; X. Wang, Yao, & Wang, 2021), trace fossils (Ding, Duan, Wu, & Cao, 2021), and carbon isotopic chemostratigraphy of the Permian (Q. Ma, et al, 2021; Wei, Tang, Gu, Fu, & Zhang, 2021).…”

“…Six and seven papers address sedimentary and palaeontology of Guangxi and northern Xinjiang Province, respectively (F. Chen, Xue, et al, 2021; Cui & Cao, 2021; Z. Guo, Chen, Harper, & Huang, 2021; W. Guo, Nie, Lu, et al, 2021; X. Huang, Wang, et al, 2021; Q. Ma, Ye, et al, 2021; X. Shi, Lang, et al, 2021; T. M. Shi, Li, et al, 2021; Song et al, 2021; Wan et al, 2021; Wang F. et al, 2021; Wei et al, 2021; Zong et al, 2021; Figure 1). Outside China, two papers document fossil materials from Western Australia and Malaysia, respectively ( Tang et al , 2021; H. Yang et al , 2021).…”
