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… 

Exceptional soft tissues preservation in a mummified frog-eating Eocene salamander

Internal structures composed of soft tissues preserved in three dimensions are now identified: a lung, the spinal cord, a lumbosacral plexus, the digestive tract, muscles and urogenital organs that may be cloacal glands and shed light on the ecology of this salamander.

On the purported presence of fossilized collagen fibres in an ichthyosaur and a theropod dinosaur

It is found that there is no evidence to support the idea that the integumentary structures seen in the two taxa are collagen fibres, and it is confirmed that the most parsimonious interpretation of fossilized structures that look like feather homologues in Sinosauropteryx is that they are indeed the remains of featherhomologues.

A RECONSIDERATION OF COMPSOGNATHUS FROM THE UPPER TITHONIAN OF CANJUERS, SOUTHEASTERN FRANCE

This study proposes that C. corallestris is a subjective junior synonym of Compsognathus longipes from Bavaria, which is nearly identical to those of the French specimen, and the differences are related to ontogenetic or within-species variation or are caused by preservational factors.

The occurrence of clavicles within Dinosauria: Implications for the homology of the avian furcula and the utility of negative evidence

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

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.
