The cranial anatomy of the flat-skulled hadrosaurine Edmontosaurus regalis (Ornithischia: Hadrosauridae) is extensively described here, based on holotype and paratype collected from middle part Horseshoe Canyon Formation in southern Alberta. Focus given to previously undocumented features ontogenetic phylogenetic importance. This description facilitates overall osteological comparisons between E. other hadrosaurids (especially annectens), revises diagnosis regalis, which a new autapomorphy...
Southwestern Henan Province in central China contains many down-faulted basins, including the Xixia Basin where Upper Cretaceous continental sediments are well exposed. The Majiacun Formation is a major dinosaur-bearing stratigraphic unit that occurs this basin.A new basal hadrosauroid dinosaur, Zhanghenglong yangchengensis gen. et sp. nov., named based on newly collected specimens from middle Santonian of Zhoujiagou Village, Basin. Two transitional features between hadrosauroids and...
The close affinity between Edmontosaurus and Shantungosaurus is corroborated on the basis of following shared features: an occipital condyle deflected strongly posteroventrally; a posterodorsally reflected, lip-shaped oral margin premaxilla, with deep, oval concavity at anteromedial corner bone; well-demarcated posterodorsal deeply excavated circumnarial fossa formed by prominent arched ridge along entire posterior half lateroventral border nasal; anteroposteriorly broad jugal process...
Tanius is the earliest named ornithischian genus from China. Since 1929, three species of this genus, namely T. sinensis (the type species), "T. chingkankouensis" and laiyangensis", have been reported based on remains Wangshi Group Shandong, China, were previously recognized as hadrosaurines. Following recent achievement consensus phylogenetic placement outside Hadrosauridae, assignments laiyangensis" material hadrosaurid origin to become problematic. Related taxonomic issues therefore need...
A second basal hadrosauroid dinosaur, Zuoyunlong huangi gen. et sp. nov., is reported from the early Late Cretaceous Zhumapu Formation in Zuoyun County, Shanxi Province, northern China. preserves a partial right ilium and ischium unique having very short postacetabular process 50% as long iliac central plate. Our cladistic analysis recovers most hadrosauroid, with sister taxon relationship Probactrosaurus late Early of Inner Mongolia. Including Zuoyunlong, four Cenomanian hadrosauroids have...
Abstract In studying the skeletal allometry of any vertebrate, it is important to sample ontogenetic extremes ensure accuracy parameter estimation; this particularly true for fossil taxa, where sampling series incomplete and sporadic. Previous studies have examined in skull duck‐billed dinosaur Gryposaurus notabilis , but these did not include individuals smaller than ~65% maximum known size (based on linear dimensions). Here, we report two smallest examples species (a mostly complete...
The osteology and taxonomy of the lambeosaurine Sahaliyania elunchunorum from upper Yuliangzi Formation (middle Maastrichtian) are reevaluated herein. Based on detailed morphological comparisons among hadrosauroids, we argue that Wulaga specimens, most which were previously ascribed to S. elunchunorum, display a combination features is typical Amurosaurus riabinini Udurchukan at Blagoveschensk locality. This includes several anterodorsally-posteroventrally oriented lateral foramina maxilla...
