Titre: The oldest dinosaur? A Middle Triassic dinosauriform from Tanzania Auteur:Nesbitt, Sterling J; Barrett, Paul M; Werning, Sarah; Sidor, Christian A; Charig, Alan J Sujet:Biological Evolution ; Dinosaurs -- Anatomy & Histology Description:
The rise of dinosaurs was a major event in vertebrate history, but the timing of the origin and early diversification of the group remain poorly constrained. Here, we describe Nyasasaurus parringtoni gen. et sp. nov., which is identified as either the earliest known member of, or the sister-taxon to, Dinosauria. Nyasasaurus possesses a unique combination of dinosaur character states and an elevated growth rate similar to that of definitive early dinosaurs. It demonstrates that the initial dinosaur radiation occurred over a longer timescale than previously thought (possibly 15 Myr earlier), and that dinosaurs and their immediate relatives are better understood as part of a larger Middle Triassic archosauriform radiation. The African provenance of Nyasasaurus supports a southern Pangaean origin for Dinosauria.

Titre: The anatomy of Teleocrater Rhadinus, an early avemetatarsalian from the lower portion of the Lifua Member of the Manda Beds (Middle Triassic) Auteur:Nesbitt, Sterling J; Butler, Richard J; Ezcurra, Martín D; Charig, Alan J; Barrett, Paul M Sujet:Geology Description:
Bird-line archosaurs (= Avemetatarsalia, the clade containing birds, dinosaurs, pterosaurs, and their kin) originated in the Triassic Period. However, the earliest evolution of this group is poorly documented because fossils are extremely rare and consist mostly of postcrania. Here, we document...

The diverse assemblage of extinct archosaur species known from the Manda Beds of Tanzania has provided key insights into the timing and tempo of the early part of the archosaur radiation during the Middle Triassic. Several archosaur specimens were collected from the Manda Beds in 1933 by F....

Titre: Archaeopteryx is not a Forgery Auteur:Charig, Alan J.; Greenaway, Frank; Milner, Angela C.; Walker, Cyril A.; Whybrow, Peter J. Description:
Archaeopteryx lithographica might be regarded as the most important zoological species known, fossil or recent. Its importance lies not in that its transitional nature is unique--there are many such transitional forms at all taxonomic levels--but in the fact that it is an obvious and comprehensible example of organic evolution. There have been recent allegations that the feather impressions on Archaeopteryx are a forgery. In this report, 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.

Titre: The systematic position of Baryonyx walkeri, in the light of Gauthier's reclassification of the Theropoda Auteur:Charig, Alan J; Milner, Angela C Editeur:
Cambridge University Press
Date:
30 November 1990
Sujet:Geology Description:
AbstractContinuing preparation of the unique specimen of Baryonyx walkeri has already provided much additional information on this recently described dinosaur, including the startling observation that the lower teeth are twice as numerous per unit length of jaw as are the upper teeth. The characters of the animal demonstrate conclusively that it is a theropod dinosaur, that it is not a spinosaurid, that it cannot be fitted satisfactorily into Gauthier's recent classification of the theropods, and that it is sufficiently distinctive from all other theropods to justify the present authors' earlier proposal of a new family Baryonychidae. Some fragmentary material described from the Late Cretaceous of Niger and Morocco and referred to the Spinosauridae is more likely to be baryonychid.IntroductionOur lecture at the Drumheller Symposium on a new theropod dinosaur from the Wealden of Surrey was followed by our publication (Charig and Milner 1986) of a preliminary account of the animal,...
