Therizinosaurs are highly modified, probably herbivorous, theropods from the Upper
Cretaceous of Asia and North America. They are characterized by an extensively …

Therizinosaurs are unusual theropods from the Upper Cretaceous of Asia and North
America. North American representatives include Falcarius utahensis from central Utah …

The hindlimb musculature of the basal therizinosaur Falcarius utahensis is reconstructed
using observable muscle scars, information from extant birds and crocodylians, and current …

Soft tissue reconstructions of fossil vertebrates provide valuable data and support for
functional interpretations. Here, we present the pelvic and hindlimb muscular reconstruction …

The recent discovery of a dense, paucispecific bonebed from the Early Cretaceous Cedar
Mountain Formation, central Utah, has yielded new information on the morphology and …

The forelimbs of nonavian theropod dinosaurs have been the subject of considerable study
and speculation due to their varied morphology and role in the evolution of flight. Although …

Therizinosaurs represent a highly unusual clade of herbivorous theropods from the
Cretaceous of North America and Asia. Following descriptions of the basicrania of the North …

Nothronychus graffami was a large therizinosaur from the Upper Cretaceous of North
America. Much of the skeleton is well‐preserved and relatively undistorted. The synovial …

In this article, we develop a new reconstruction of the pelvic and hindlimb muscles of the
large theropod dinosaur Tyrannosaurus rex. Our new reconstruction relies primarily on …

Piatnitzkysauridae were Jurassic theropods that represented the earliest diverging branch of
Megalosauroidea, being one of the earliest lineages to have evolved moderate body size …
