A New Specimen of Archaeopteryx

  title={A New Specimen of Archaeopteryx},
  author={Peter Wellnhofer},
  pages={1790 - 1790}
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. 

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.

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.

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.

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.

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,

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.

Description and ontogenetic assessment of a new Jehol microraptorine

It is confirmed that this microraptorine theropod was around a single year in age and still growing at death, but that the growth had slowed, which indicates that presence of a variety of feather types, including filamentous feathers, pennaceous primaries, and long rectrices, likely used for ornamentation, preceded skeletal maturity and full adult size.

A new microraptorine theropod from the Jehol Biota and growth in early dromaeosaurids

Comparison of histology in the new taxon and Sinornithosaurus indicates that macroscopic signs of maturity developed after the first year, but before cessation of growth, demonstrating that nonhistological indicators of adulthood may be misleading when applied to dromaeosaurids.



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.
