A new specimen of the primordial bird Archaeopteryx is reported from the Upper Jurassic Solnhofen Limestone of Bavaria. This "Solnhofen specimen" is the largest of now six skeletal specimens and shows dose similarities with the London specimen. It is therefore assigned to Archaeopteryx lithographica Meyer. Clear impressions of the feather shafts of the left wing are preserved.

The peculiarities of Archaeopteryx's preservation, which they cite as evidence that the feathers cannot be genuine, are features shared with the many other fossils from the Solnhofen limestone. Expand
A new genus and species for the largest specimen of Archaeopteryx
A combination of large size and details of the pelvic limb suggests a locomotor specialization different from that of Archaeopteryx. Expand
Allometric Scaling in the Earliest Archaeopteryx lithographica
Allometric patterns suggest that Archaeopteryx was likely a homeothermic endotherm with rapid growth and precocial abilities for running and flying, as compared to growth gradients of other dinosaurs, extant ectotherms, and extant endotherms. Expand
New Specimens of Microraptor zhaoianus (Theropoda: Dromaeosauridae) from Northeastern China
New specimens of the diminutive theropod dinosaur Microraptor zhaoianus are described, found to be the sister taxon to other dromaeosaurs and apparently small size is primitive for Deinonychosauria, which has implications for bird origins. Expand
Two feathered dinosaurs from northeastern China
Current controversy over the origin and early evolution of birds centres on whether or not they are derived from coelurosaurian theropod dinosaurs. Here we describe two theropods from the UpperExpand
Diversification in an Early Cretaceous avian genus: evidence from a new species of Confuciusornis from China
A new species of Confuciusornis, the oldest known beaked bird, is erected based on a nearly complete fossil from the Early Cretaceous Yixian Formation of western Liaoning, northeast China, which suggests an arboreal habit of the new bird. Expand
The oldest Archaeopteryx (Theropoda: Avialiae): a new specimen from the Kimmeridgian/Tithonian boundary of Schamhaupten, Bavaria
The iconic primeval bird Archaeopteryx was so far mainly known from the Altmühltal Formation of Bavaria, southern Germany, with one specimen having been found in the overlying Mörnsheim Formation, but a new specimen from the earliest Tithonian Painten Formation of Schamhaupten (Bavaria) represents the so far oldest representative of the genus.

A Small Derived Theropod from Öösh, Early Cretaceous, Baykhangor Mongolia
Abstract A new theropod dinosaur, Shanag ashile, from the Early Cretaceous Öösh deposits of Mongolia is described here. The new specimen (IGM 100/1119) comprises a well-preserved right maxilla,Expand
Evidence from Claw Geometry Indicating Arboreal Habits of Archaeopteryx
Examination of claw geometry shows that modern ground- and tree-dwelling birds can be distinguished on the basis of claw curvature, and that Archaeopteryx appears to have been a perching bird, not a cursorial predator. Expand
Jeholornis compared to Archaeopteryx, with a new understanding of the earliest avian evolution
The recently reported Jeholornis represents the only known bird with a complete long skeletal tail except for Archaeopteryx, and it is concluded that the common ancestor of birds must have a more primitive tail than that in Archaeoporationx, confirming the side branch position of Archaeoperyx in the early avian evolution.

The paleobiology and phylogenetic position of Archaeopteryx
It is suggested that the early stage in avian flight was an arboreal tetrapod and no intermediate bipedal stage was required and Archaeopteryx was probably an accomplished glider with some powered flight potential. Expand
Archaeopteryx Is Not a Forgery
Proof of authenticity is provided by exactly matching hairline cracks and dendrites on the feathered areas of the opposing slabs, which show the absence of the artificial cement layer into which modern feathers could have been pressed by a forger. Expand
