The gauge structure of generalised diffeomorphisms
A bstractWe investigate the generalised diffeomorphisms in M-theory, which are gauge transformations unifying diffeomorphisms and tensor gauge transformations. After giving an En(n)-covariantExpand

Georgenthalia clavinasica, A New Genus and Species of Dissorophoid Temnospondyl from the Early Permian of Germany, and the Relationships of the Family Amphibamidae
Abstract Georgenthalia clavinasica, a new genus and species of amphibamid dissorophoid temnospondyl, is represented by a small, complete, postmetamorphic skull from the Lower Permian BromackerExpand

Duality invariant actions and generalised geometry
A bstractWe construct the non-linear realisation of the semi-direct product of E11 and its first fundamental representation at lowest order and appropriate to spacetime dimensions four to seven. ThisExpand

Generalized geometry and M theory
We reformulate the Hamiltonian form of bosonic eleven dimensional supergravity in terms of an object that unifies the three-form and the metric. For the case of four spatial dimensions, the dualityExpand

The local symmetries of M-theory and their formulation in generalised geometry
A bstractIn the doubled field theory approach to string theory the T-duality group is promoted to a manifest symmetry at the expense of replacing ordinary Riemannian geometry with generalisedExpand

The anatomy and relationships of the Lower Permian reptile Araeoscelis
ABSTRACT Two recently discovered skeletons of the enigmatic Lower Permian reptile Araeoscelis provide important, additional information on its osteology and permit a reassessment of its phylogeneticExpand

M-theory branes and their interactions
In recent years there has been some progress in understanding how one might model the interactions of branes in M-theory despite not having a fundamental perturbative description. The goal of thisExpand

A late-surviving basal theropod dinosaur from the latest Triassic of North America
The oldest theropod dinosaurs are known from the Carnian of Argentina and Brazil. However, the evolutionary diversification of this group after its initial radiation but prior to theExpand

A NEW SPECIMEN OF HESPEROSUCHUS AGILIS FROM THE UPPER TRIASSIC OF NEW MEXICO AND THE INTERRELATIONSHIPS OF BASAL CROCODYLOMORPH ARCHOSAURS
Abstract An articulated partial skeleton, including a nearly complete skull and left forelimb, of a crocodylomorph reptile from the Upper Triassic Chinle Formation of Ghost Ranch, New Mexico, isExpand
