Sauropod Trackway Reflecting an Unusual Walking Pattern from the Early Cretaceous of Shandong Province, China
ABSTRACT The trackway of a quadrupedal dinosaur from the Early Cretaceous (Albian) Qingquan tracksite (Tancheng, Shandong Province) is redescribed, and the trackmaker is identified as a sauropod. TheExpand
A new narrow-gauge sauropod trackway from the Cenomanian Candeleros Formation, northern Patagonia, Argentina
Abstract Dinosaurs are extremely abundant in the Upper Cretaceous Neuquen Group of the Neuquen Basin (Argentina). Nevertheless, while osteological remains are rich the ichnological record is moreExpand
Dinosaur footprints from the Duntulm Formation (Bathonian, Jurassic) of the Isle of Skye
Synopsis The first in situ dinosaur tracks from Scotland were discovered at the top of the Duntulm Formation (Bathonian, Jurassic) near to Staffin in northeastern Skye. Fifteen individual tridactylExpand
First report of sauropod tracks from the Upper Jurassic Tianchihe Formation of Guxian County, Shanxi Province, China
Abstract This paper presents the first report of sauropod tracks from the Upper Jurassic of Shanxi Province, China. Dinosaur tracks appear concentrated in five trackways, in different stratigraphicExpand
Evidence for targeted elasmobranch predation on thalassinidean shrimp in the Miocene Taliao Formation, NE Taiwan
Terrestrial and marine invertebrate organisms both leave records of their activities in the sediment in the form of trace fossils, at least during certain stages of their ontogeny. In contrast, traceExpand
Middle Jurassic Tracks of Sauropod Dinosaurs in a Deep Karst Cave in France
ABSTRACT Although the deep galleries of natural underground cavities are difficult to access and are sometimes dangerous, they have the potential to preserve trace fossils. Here, we report on theExpand
Anatomy of a Jurassic Theropod Trackway from Ardley, Oxfordshire, U.K.
Ardley Quarry, Oxfordshire, central England, preserves a most remarkable ichnological record of dinosaur activity on a single 168 Ma old trackway-bearing horizon. This horizon reveals over 40Expand
The Mesozoic Vertebrate Radiation in Terrestrial Settings
In the last three decades vertebrate ichnology went through a renaissance due the discovery of new tracksites and the application of rigorous analytic methods (e.g., synapomorphy analyses). ThisExpand
Diprotodontid Footprints from the Pliocene of Central Australia
ABSTRACT The first Pliocene marsupial fossil trackways from Australia are described. The trackways, attributed to Euowenia grata (De Vis) (Diprotodontoidea, Marsupialia), occur in the middleExpand


Biomechanics: Dinosaur locomotion from a new trackway
A unique dual-gauge trackway from a bipedal theropod dinosaur from the Middle Jurassic in this locality is discovered, which indicates that these large theropods were able to run and that they used different hindlimb postures for walking and running. Expand
The Evolutionary History of Sauropod Dinosaurs
Forked chevrons, which have played such an important role in previous studies of sauropod phylogeny, are here considered to have evolved twice within the Sauropoda, which may reflect a correlation between chevron shape and the use of the tail as a weapon within these twosauropod families. Expand
Titanosaurs and the origin of wide-gauge trackways; a biomechanical and systematic perspective on sauropod locomotion
It is argued that skeletal morphology is respon- sible for gauge differences and integrate data from locomotor biomechanics and systematics with the track record to predict the hindlimb morphology of wide-gauge trackmakers, implying that titanosaurs were unique among sauropods in having a more varied repertoire of locomotor habits. Expand
The phylogenetic relationships of sauropod dinosaurs
The results suggest that there are dangers inherent in the view that ‘higher’ level sauropod phylogeny can be accurately reconstructed using only a small number of well-known taxa, and that the results of the randomization tests indicate that the data-matrix probably contains a strong phylogenetic ‘signal’.
