The 438–370-million-year-old galeaspids, diversified armoured jawless vertebrates ('ostracoderms') from China and northern Vietnam, were assumed to have a benthic feeding habit in coastal, marine environment. Here, we describe two new genera of galeaspid fishes, Platylomaspis gen. nov. Nanningaspis the Middle Palaeozoic China. forms are characterized by rostral process strikingly broad ventral rim, clustered with Gumuaspis form family, Gumuaspidae, which represents most primitive clade...
Abstract Galeaspids are extinct jawless relatives of living jawed vertebrates whose contribution to understanding the evolutionary assembly gnathostome bodyplan has been limited by absence postcranial remains. Here, we describe Foxaspis novemura gen. et sp. nov., based on complete articulated remains from a newly discovered Konservat-Lagerstätte in Early Devonian (Pragian, ∼410 Ma) Guangxi, South China. F. had broad, circular dorso-ventrally compressed headshield, slender trunk and strongly...
Abstract New discovery of the early Silurian fossil fish Changxingaspis (Xiushuiaspidae, Galeaspida), nianzhongi sp. nov. and C. gui , are described from Tataertag Formation in Tarim Basin Kangshan Zhejiang Province, respectively. mainly differs shape median dorsal opening that is transverse elliptic with a width/length ratio about 3.0, long lateral canals extending to margin headshield, second canal dichotomous branchings. Discovery provide direct evidence on specific level for correlation...
The spiracular region, comprising the hyomandibular pouch together with mandibular and hyoid arches, has a complex evolutionary history. In living vertebrates, embryonic may disappear in adult, develop into small opening between palatoquadrate hyomandibula containing single gill-like pseudobranch, or create middle ear cavity, but it never develops fully formed gill two hemibranchs. belief that complete must be ancestral condition led some 20th century researchers to search for such arches...
Galeaspids are an endemic clade of jawless stem-gnathostomes known as ostracoderms. Their existence illuminates how specific characteristics developed in jawed vertebrates. Sinogaleaspids particular interest among the galeaspids but their monophyly is controversial because little about Sinogaleaspis xikengensis . Newly discovered sinogaleaspids from Lower Silurian Jiangxi, China provide a wealth data and diagnostic features used to establish new genus, Rumporostralis gen. nov., for A...
Abstract A new genus and species of agnathan Eugaleaspidiformes (Galeaspida), Yongdongaspis littoralis gen. et sp. nov., is described from the Llandovery (lower Silurian) Huixingshao Formation at Yongdong Town, Xiushan County, Chongqing, southwestern China. This Telychian taxon morphologically exhibits some transitional states between Sinogaleaspidae a cluster higher eugaleaspidiforms containing Tridensaspidae, Eugaleaspidae, Yunnanogaleaspis , Nochelaspis which we term here as ‘eugaleaspid...
A new species of Dayongaspidae, Dayongaspis colubra sp. nov., is described from the Telychian (Llandovery, Silurian) Xiushan Formation at Maoyanhe Town, Zhangjiajie, Hunan Province, China. The distinguished type D. hunanensis by its larger-sized headshield, tiny and dense granular tubercles, triangular-shaped inner cornual processes. Additionally, it reveals more galeaspid plesiomorphic characters than hunanensis, such as inverted splayed posterior supraorbital canals (soc2) paired...
Abstract Wang, B. & Gai, Z.K., 2014. A sea scorpion claw from the Lower Devonian of China (Chelicerata: Eurypterida). Alcheringa 38, XX–XX. ISSN 0311–5518.An isolated chelicera (claw) a pterygotid eurypterid is described Xitun Formation Yunnan Province, China. It different chelicerae other pterygotids in having four principal denticles and at least intermediate between on both rami. This Chinese pterygotid, estimated about 70 cm long, was top predator that probably hunted small, primitive...
A new genus and species of the Galeaspida Qushiaspis elaia gen. et sp. nov. is described from Lower Devonian Xujiachong Formation Qujing, Yunnan Province, southwestern China. The displays diagnostic characters Huananaspidiformes including a large oval-shaped median dorsal opening, slender rostral process, lateral positioned orbital posteriorly projecting cornual inner processes. It bears closer resemblance to Gantarostrataspidae than Sanchaspidae Huananaspidae in lacking laterally processes,...
A new genus and species of galeaspid, Falxcornus liui gen. et sp. nov., is described from the Xishancun Formation (Lochkovian, Lower Devonian) in Qujing, Yunnan, China. The taxon displays a suite diagnostic characters Eugaleaspiformes strikingly resembles tridensaspids Tridensaspis Pterogonaspis its sickle-like complex cornual inner processes, leaf-like median dorsal opening posteriorly placed level with centre orbital opening, but clearly differs these genera lacking rostral process...
The first Eugaleaspiforme fish, Jiangxialepis rongi sp. nov., from the lower Telychian (Llandovery, Silurian) Tataertag Formation in Tarim Basin is described and its palaeogeographic significance evaluated. new species can be assigned to family Shuyuidae distinguished J. retrospina jiujiangensis by comparatively broader headshield, ornamentation, serrated margin of headshield median dorsal opening. discovery provides direct fossil evidence for correlation marine red beds between South China...
Abstract A new species of Shuyuidae (Eugaleaspiformes, Galeaspida), Jiangxialepis jiujiangensis sp. nov., is described from the lower Telychian (Llandovery, Silurian) Qingshui Formation in Jiujiang, Jiangxi Province, China. The differs type J. retrospina Wuhan, Hubei Province its sharp and posteriorly positioned median dorsal spine narrow spine‐shaped inner cornual processes. Silurian strata Xiushui–Wuning area has provided a standard framework for correlation shallow marine red beds South...
