Basal abelisaurid and carcharodontosaurid theropods from the Lower Cretaceous Elrhaz Formation of Niger PAUL C. SERENO and STEPHEN L. BRUSATTE Sereno, P.C. and Brusatte, S.L. 2008. Basal abelisaurid and carcharodontosaurid theropods from the Lower Cretaceous Elrhaz Formation of Niger. Acta Palaeontologica Polonica 53 (1): 15–46. We report the discovery of basal abelisaurid and carcharodontosaurid theropods from the mid Cretaceous (Aptian– Albian, ca. 112 Ma) Elrhaz Formation of the Niger Republic. The abelisaurid, Kryptops palaios gen. et sp. nov., is repre− sented by a single individual preserving the maxilla, pelvic girdle, vertebrae and ribs. Several features, including a maxilla textured externally by impressed vascular grooves and a narrow antorbital fossa, clearly place Kryptops palaios within Abelisauridae as its oldest known member. The carcharodontosaurid, Eocarcharia dinops gen. et sp. nov., is repre− sented by several cranial bones and isolated teeth. Phylogenetic analysis places it as a basal carcharodontosaurid, similar to Acrocanthosaurus and less derived than Carcharodontosaurus and Giganotosaurus. The discovery of these taxa sug− gests that large body size and many of the derived cranial features of abelisaurids and carcharodontosaurids had already evolved by the mid Cretaceous. The presence of a close relative of the North American genus Acrocanthosaurus on Af− rica suggests that carcharodontosaurids had already achieved a trans−Tethyan distribution by the mid Cretaceous.

v^ Official Journal of the Biology Unit of the American Topical Association 10 Vol. 40(4) DINOSAURS ON STAMPS by Michael K. Brett-Surman Ph.D. Dinosaurs are the most popular animals of all time, and the most misunderstood. Dinosaurs did not fly in the air and did not live in the oceans, nor on lake bottoms. Not all large "prehistoric monsters" are dinosaurs. The most famous NON-dinosaurs are plesiosaurs, moso- saurs, pelycosaurs, pterodactyls and ichthyosaurs. Any name ending in 'saurus' is not automatically a dinosaur, for' example, Mastodonto- saurus is neither a mastodon nor a dinosaur - it is an amphibian! Dinosaurs are defined by a combination of skeletal features that cannot readily be seen when the animal is fully restored in a flesh reconstruction. Because of the confusion, this compilation is offered as a checklist for the collector. This topical list compiles all the dinosaurs on stamps where the actual bones are pictured or whole restorations are used. It excludes footprints (as used in the Lesotho stamps), cartoons (as in the 1984 issue from Gambia), silhouettes (Ascension Island # 305) and unoffi- cial issues such as the famous Sinclair Dinosaur stamps. The name "Brontosaurus", which appears on many stamps, is used with quotation marks to denote it as a popular name in contrast to its correct scientific name, Apatosaurus. For those interested in a detailed encyclopedic work about all fossils on stamps, the reader is referred to the forthcoming book, 'Paleontology - a Guide to the Postal Materials Depicting Prehistoric Lifeforms' by Fran Adams et. al. The best book currently in print is a book titled 'Dinosaur Stamps of the World' by Baldwin & Halstead. -

A New Raptorial Dinosaur with Exceptionally Long Feathering Provides Insights Into Dromaeosaurid flight Performance
ARTICLE Received 11 Apr 2014 | Accepted 11 Jun 2014 | Published 15 Jul 2014 DOI: 10.1038/ncomms5382 A new raptorial dinosaur with exceptionally long feathering provides insights into dromaeosaurid flight performance Gang Han1, Luis M. Chiappe2, Shu-An Ji1,3, Michael Habib4, Alan H. Turner5, Anusuya Chinsamy6, Xueling Liu1 & Lizhuo Han1 Microraptorines are a group of predatory dromaeosaurid theropod dinosaurs with aero- dynamic capacity. These close relatives of birds are essential for testing hypotheses explaining the origin and early evolution of avian flight. Here we describe a new ‘four-winged’ microraptorine, Changyuraptor yangi, from the Early Cretaceous Jehol Biota of China. With tail feathers that are nearly 30 cm long, roughly 30% the length of the skeleton, the new fossil possesses the longest known feathers for any non-avian dinosaur. Furthermore, it is the largest theropod with long, pennaceous feathers attached to the lower hind limbs (that is, ‘hindwings’). The lengthy feathered tail of the new fossil provides insight into the flight performance of microraptorines and how they may have maintained aerial competency at larger body sizes. We demonstrate how the low-aspect-ratio tail of the new fossil would have acted as a pitch control structure reducing descent speed and thus playing a key role in landing. 1 Paleontological Center, Bohai University, 19 Keji Road, New Shongshan District, Jinzhou, Liaoning Province 121013, China. 2 Dinosaur Institute, Natural History Museum of Los Angeles County, 900 Exposition Boulevard, Los Angeles, California 90007, USA. 3 Institute of Geology, Chinese Academy of Geological Sciences, 26 Baiwanzhuang Road, Beijing 100037, China. 4 University of Southern California, Health Sciences Campus, BMT 403, Mail Code 9112, Los Angeles, California 90089, USA. -
Late Jurassic Theropod Dinosaur Bones from the Langenberg Quarry
Late Jurassic theropod dinosaur bones from the Langenberg Quarry (Lower Saxony, Germany) provide evidence for several theropod lineages in the central European archipelago Serjoscha W. Evers1 and Oliver Wings2 1 Department of Geosciences, University of Fribourg, Fribourg, Switzerland 2 Zentralmagazin Naturwissenschaftlicher Sammlungen, Martin-Luther-Universität Halle-Wittenberg, Halle (Saale), Germany ABSTRACT Marine limestones and marls in the Langenberg Quarry provide unique insights into a Late Jurassic island ecosystem in central Europe. The beds yield a varied assemblage of terrestrial vertebrates including extremely rare bones of theropod from theropod dinosaurs, which we describe here for the first time. All of the theropod bones belong to relatively small individuals but represent a wide taxonomic range. The material comprises an allosauroid small pedal ungual and pedal phalanx, a ceratosaurian anterior chevron, a left fibula of a megalosauroid, and a distal caudal vertebra of a tetanuran. Additionally, a small pedal phalanx III-1 and the proximal part of a small right fibula can be assigned to indeterminate theropods. The ontogenetic stages of the material are currently unknown, although the assignment of some of the bones to juvenile individuals is plausible. The finds confirm the presence of several taxa of theropod dinosaurs in the archipelago and add to our growing understanding of theropod diversity and evolution during the Late Jurassic of Europe.

The Anatomy and Phylogenetic Relationships of Antetonitrus Ingenipes (Sauropodiformes, Dinosauria): Implications for the Origins of Sauropoda
THE ANATOMY AND PHYLOGENETIC RELATIONSHIPS OF ANTETONITRUS INGENIPES (SAUROPODIFORMES, DINOSAURIA): IMPLICATIONS FOR THE ORIGINS OF SAUROPODA Blair McPhee A dissertation submitted to the Faculty of Science, University of the Witwatersrand, in partial fulfilment of the requirements for the degree of Master of Science. Johannesburg, 2013 i ii ABSTRACT A thorough description and cladistic analysis of the Antetonitrus ingenipes type material sheds further light on the stepwise acquisition of sauropodan traits just prior to the Triassic/Jurassic boundary. Although the forelimb of Antetonitrus and other closely related sauropododomorph taxa retains the plesiomorphic morphology typical of a mobile grasping structure, the changes in the weight-bearing dynamics of both the musculature and the architecture of the hindlimb document the progressive shift towards a sauropodan form of graviportal locomotion. Nonetheless, the presence of hypertrophied muscle attachment sites in Antetonitrus suggests the retention of an intermediary form of facultative bipedality. The term Sauropodiformes is adopted here and given a novel definition intended to capture those transitional sauropodomorph taxa occupying a contiguous position on the pectinate line towards Sauropoda. The early record of sauropod diversification and evolution is re- examined in light of the paraphyletic consensus that has emerged regarding the ‘Prosauropoda’ in recent years. iii ACKNOWLEDGEMENTS First, I would like to express sincere gratitude to Adam Yates for providing me with the opportunity to do ‘real’ palaeontology, and also for gladly sharing his considerable knowledge on sauropodomorph osteology and phylogenetics. This project would not have been possible without the continued (and continual) support (both emotionally and financially) of my parents, Alf and Glenda McPhee – Thank you.
