The Lower Cretaceous Pietraroia Plattenkalk (Benevento Province, southern Italy) has been known since the eighteenth century for its beautifully preserved fossil fishes. During Albian time (about 113 Myr ago), deposition of fine marly limestone in a shallow lagoonal environment, affected by cyclic periods of low oxygen levels, led to exceptional preservation of soft tissue in a juvenile theropod. The specimen, diagnosed here as Scipionyx samniticus gen. et sp. nov., is the first dinosaur ever…

Abstract Within the past decade exceptional preservation of original organic components have been reported from several dinosaurian families, including members of Sauropodomorpha. Here we document
Exceptional soft tissues preservation in a mummified frog-eating Eocene salamander
Fossils are almost always represented by hard tissues but we present here the exceptional case of a three-dimensionally preserved specimen that was ‘mummified’ (likely between 40 and 34 million years

On the purported presence of fossilized collagen fibres in an ichthyosaur and a theropod dinosaur
Since the discovery of exceptionally preserved theropod dinosaurs with soft tissues in China in the 1990s, there has been much debate about the nature of filamentous structures observed in some

Dinosaur Systematics: Theropod teeth from the Judith River Formation of southern Alberta, Canada
TLDR
The identification of theropod teeth has the potential of refining stratigraphic determinations, extending temporal and geographic ranges, indicating relationships, and allowing paleoecological statements to be made on the relative diversity or abundance of certain taxa.

New information on the anatomy and relationships of Dromaeosaurus albertensis (Dinosauria: Theropoda)
TLDR
Repreparation and restudy of the holotype of Dromaeosaurus albertensis has produced new anatomical information useful for evaluating the relationships of dromaeosaurids.
The phylogenetic position of the Tyrannosauridae; implications for theropod systematics
TLDR
The inclusion of the Tyrannosauridae within Maniraptora suggests a major adaptive radiation of coelurosaurs within Cretaceous Asiamerica comparable to contemporaneous radiations in various herbivorous dinosaurian clades.
Functional Morphology in Vertebrate Paleontology
TLDR
This paper presents a meta-analysis of the evolution of the hindlimb and tail from basal theropods to birds and the consequences of skull flattening in crocodilians and an analysis of the posture and gait of ceratopsian dinosaurs.
The occurrence of clavicles within Dinosauria: Implications for the homology of the avian furcula and the utility of negative evidence
TLDR
The test of congruence using the currently accepted phylogenetic relationships within the Ornithodira suggests that the loss of clavicles may be plesiomorphic within Dinosauria, raising the possibility that the furcula of birds may be a neomorph, or may represent the reappearance of a “lost” structure.
A Velociraptor wishbone
TLDR
The discovery of a furcula is reported in Dromaeosauridae, a group posited to be the closest relative of birds, and the uncertainty of whether this absence is real or an artefact of preservation obscures the evolutionary history of this structure.
