Abstract: We herein describe an associated partial postcranial skeleton of a theropod dinosaur discovered in the Lower Cretaceous Xinminpu Group of the Yujingzi Basin, in the Jiuquan area of Gansu Province, northwestern China. Features of its humerus, such as strongly expanded proximal and distal ends, a well developed medial tuberosity, distal condyles expressed on the humeral cranial surface, and a hypertrophied entepicondyle, definitively establish the therizinosauroid affinities of the…

An Unusual Basal Therizinosaur Dinosaur with an Ornithischian Dental Arrangement from Northeastern China

A nearly complete, articulated skeleton of a new basal therizinosaur from the Early Cretaceous Yixian Formation of Jianchang County, western part of Liaoning Province is reported, which sheds light on the understanding of anatomy of basal therizinosaurs.

Osteology of Falcarius utahensis (Dinosauria: Theropoda): characterizing the anatomy of basal therizinosaurs

Results of this study reveal a significant degree of morphological disparity between Falcarius utahensis and the evidently coeval primitive theriz Dinosaur Beipiaosaurus inexpectus and help characterize morphological transformations occurring in the therizinosaur lineage that are of phylogenetic significance, particularly with regard to the highly derived presacral axial column.

Therizinosauroidea (Dinosauria: Theropoda) from the Upper Cretaceous of Uzbekistan

A giant ornithomimosaur from the Early Cretaceous of China

Together with the co-eval and sympatric therizinosaur Suzhousaurus and the oviraptorosaur Gigantraptor, Beishanlong provides evidence for the parallel evolution of gigantism in separate lineages of beaked and possibly herbivorous coelurosaurs within a short time span in Central Asia.

New therizinosaurid dinosaur from the marine Osoushinai Formation (Upper Cretaceous, Japan) provides insight for function and evolution of therizinosaur claws

The record of therizinosaurs is rich in Asian countries such as Mongolia and China. Fragmentary therizinosaur specimens have been reported from the Lower and Upper Cretaceous deposits in Japan. One…

Martharaptor greenriverensis, a New Theropod Dinosaur from the Lower Cretaceous of Utah

A fragmentary skeleton of the new theropod is described and a phylogenetic analysis places M. greenriverensis within Therizinosauroidea as the sister taxon to Alxasaurus + Therizinosauridae, although support for this placement is weak.

A longirostrine tyrannosauroid from the Early Cretaceous of China

The fossil record of tyrannosauroid theropods is marked by a substantial temporal and morphological gap between small-bodied, Barremian taxa, and extremely large-bodied taxa from the latest…

Postcranial osteology of Beipiaosaurus inexpectus (Theropoda: Therizinosauria)

A detailed description of the postcranial skeletal anatomy of the holotype specimen of B. inexpectus is presented and three possible synapomorphies for more inclusive taxa (Therizinosauroidea and Therizinosauridae) are proposed and discussed.

A New Hadrosauriform Dinosaur from the Early Cretaceous of Gansu Province, China

A new basal hadrosauriform dinosaur, Xuwulong yueluni gen. et sp. nov., is reported based on an articulated specimen including a complete cranium, almost complete axial skeleton, and complete left…

A primitive therizinosauroid dinosaur from the Early Cretaceous of Utah

A new, primitive therizinosauroid is described from an extensive paucispecific bonebed at the base of the Cedar Mountain Formation of east-central Utah, indicating that this species documents the earliest known stage in the poorly understood transition from carnivory to herbivory within Therizinosauroidea.

THE PECTORAL GIRDLE AND FORELIMB OF THE PRIMITIVE THERIZINOSAUROID FALCARIUS UTAHENSIS (THEROPODA, MANIRAPTORA): ANALYZING EVOLUTIONARY TRENDS WITHIN THERIZINOSAUROIDEA

Analysis of the pectoral girdle and forelimb suggests that Theriz Dinosauridae is more appropriately defined as a derived clade including Nothronychus, Erlicosaurus, Neimongosaurus, Therizinosaurus, and Segnosaurus, and strong support is recovered for a clade containing these five genera plus “Alectrosaurus” and Erliansaurus.

A therizinosauroid dinosaur with integumentary structures from China

This new taxon from the Yixian Formation provides fresh evidence that therizinosauroids are nested within the coelurosaurian theropods, and supports the hypothesis that the filamentous integumentary structures may be homologous to the feathers of birds.

A cladistic comparison of the segnosaurs with thecodonts and early dinosaurs of the Triassic suggests that, despite their late appearance, the seGNosaurs are phylogenetic intermediates between herbivorous prosauropods and early ornithischians.
