1A New Nodosaurid Ankylosaur from the Chaochuan Formation of Dongyang, Zhejiang Province, China显示文摘Dongyangopelta yangyanensis gen. et sp. nov. from the Chaochuan Formation (Albian-Cenomanian) of Dongyang, Zhejiang Province, China is characterized: the convex anterior surface of the first presacral rod centrum strongly inflates laterally and slightly curves posteriorly; the fused pelvic shield composes of larger pebble-shaped bosses, defined by smaller tubercles or flat stretches of bone; most osteoderms are heavily roughened with notches and grooves for dermal attachment along the edge; domed triradiate osteoderm is present; sigmoid curvature of the dorsal surface of the ilium is present; the preacetabular process curves lateroventrally at the anterior end and has a shallow groove in the edge of the lateral and anterior ends and strong lateromedial expansion of the distal femur. The femoral head is well separated from the greater trochanter, indicating that Dongyangopelta is a nodosaurid ankylosaur, the second from southeast China. Phylogenetic analysis also positions this taxon in the Nodosauridae clade. Dongyangopelta differs from Zhejiangosaurus in the characters of presacral rod, ilium, and femur. Dongyangopelta represents the first ankylosaur outside North America and Europe that definitively possesses a pelvic shield with fused armor.CHEN Rongjun ZHENG Wenjie Yoichi AZUMA Masateru SHIBATA LOU Tianliang JIN Qiang JIN Xingsheng 2013Acta Geologica Sinica(English Edition)2013,87,3:1
2A new alvarezsaurid dinosaur from the Late cretaceous Qiupa Formation of Luanchuan,Henan Province,central China显示文摘An alvarezsaurid dinosaur skeleton was discovered from the Late Cretaceous Qiupa Formation of Luanchuan,Henan Province of eenttral China.It represents a new alvarezsaurid dinosaur Qiupanykus zhangi gen.et sp.nov.A phylogenetic analysis recovers Qiupanykus nested within the unresolved clade,which includes Asian and north American taxa.The skeleton of the new specimen is preserved in association with eggshells.The eggshell morphologies show that these eggs belong to oviraptorid eggs,skeletal remains of which were discovered from the same area.The alvarezsaurid skeleton associated with eggshell fragments may indicate that these eggs were broken by the strong thumb-claws of the former and that alvarezsaurid dinosaurs may be egg-eaters.Jun-chang Lu Li Xu Hua-li Chang Song-hai Jia Ji-ming Zhang Dian-song Gao Yi-yang Zhang Cheng-jun Zhang Fang Ding 2018China Geology2018,1,1:1
