Archaeopteryx: Notice of a "New" Specimen

  author={John Harold Ostrom},
  pages={537 - 538}
A fourth specimen of Archaeopteryx (cf. lithographica), the oldest known fossil bird, was recently found in the collections of the Teyler Museum in the Netherlands. Unique preservation of the horny sheaths of the manus claws provides new evidence that may be relevant to the question of the origins of avian flight. Tentative interpretation suggests a cursorial rather than arboreal origin. 
A reconsideration of the reptilian relationships of Archaeopteryx
The cladistic relationships of Archaeopteryx, the earliest known bird, are re-examined and previous hypotheses of relationships evaluated and a new version of thecodontian relationships is suggested. Expand
Archaeopteryx is an extremely important taxon to paleontology. Its basal position within Avialae often makes it the epicenter of the debate over bird origins, one of paleontology’s most significantExpand
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
Archaeopteryx FAQs
Archaeopteryx is commonly cited as an example of a transitional fossil (i.e. a form showing characters common to two separate groups). This is disputed by anti-evolutionists, who claim thatExpand
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
The skeletal taphonomy of Archaeopteryx: a quantitative approach
A new technique is described for taphonomic investigation of fossil vertebrates with a high degree of skeletal articulation and completeness, and applied to analysis of the taphonomy ofExpand
A short history of research on Archaeopteryx and its relationship with dinosaurs
Abstract Archaeopteryx, first discovered in 1861 from the Solnhofen lithographic limestone of Bavaria, is the oldest feathered animal in the fossil record. Since its discovery it has been the focusExpand
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.

Re-evaluation of the Haarlem Archaeopteryx and the radiation of maniraptoran theropod dinosaurs
Results indicate an explosive radiation of maniraptoran coelurosaurs probably in isolation in eastern Asia in the late Middle Jurassic and a rapid, at least Laurasian dispersal of the different subclades in the Late Jurassic. Expand
Amino Acid Components in Fossil Tortoiseshell from the Oligocene of the Isle of Wight
FOSSIL bones and teeth from Palaeozoic, Mesozoic and Tertiary rocks have yielded amino acid analyses which indicate the survival of collagenous material over hundreds of millions of years1. InExpand
