  • D Inosaur Paleobiology
    Topics in Paleobiology The study of dinosaurs has been experiencing a remarkable renaissance over the past few decades. Scientifi c understanding of dinosaur anatomy, biology, and evolution has advanced to such a degree that paleontologists often know more about 100-million-year-old dinosaurs than many species of living organisms. This book provides a contemporary review of dinosaur science intended for students, researchers, and dinosaur enthusiasts. It reviews the latest knowledge on dinosaur anatomy and phylogeny, Brusatte how dinosaurs functioned as living animals, and the grand narrative of dinosaur evolution across the Mesozoic. A particular focus is on the fossil evidence and explicit methods that allow paleontologists to study dinosaurs in rigorous detail. Scientifi c knowledge of dinosaur biology and evolution is shifting fast, Dinosaur and this book aims to summarize current understanding of dinosaur science in a technical, but accessible, style, supplemented with vivid photographs and illustrations. Paleobiology Dinosaur The Topics in Paleobiology Series is published in collaboration with the Palaeontological Association, Paleobiology and is edited by Professor Mike Benton, University of Bristol. Stephen Brusatte is a vertebrate paleontologist and PhD student at Columbia University and the American Museum of Natural History. His research focuses on the anatomy, systematics, and evolution of fossil vertebrates, especially theropod dinosaurs. He is particularly interested in the origin of major groups such Stephen L. Brusatte as dinosaurs, birds, and mammals. Steve is the author of over 40 research papers and three books, and his work has been profi led in The New York Times, on BBC Television and NPR, and in many other press outlets.

Brewer Editor’s note: In recognition of Dr. Nathan Brewer’s many years of dedicated service to AALAS and the community of research animal care specialists, the premier issue of JAALAS includes the following compilation of Dr. Brewer’s essays on rabbit anatomy and physiology. These essays were originally published in the ASLAP newsletter (formerly called Synapse), and are reprinted here with the permission and endorsement of that organization. I would like to thank Nina Hahn, Jane Lacher, and Nancy Austin for assistance in compiling these essays. Publishing this information in JAALAS allows Dr. Brewer’s work to become part of the searchable literature for laboratory animal science and medicine and also assures that the literature references and information he compiled will not be lost to posterity. However, readers should note that this material has undergone only minor editing for style, has not been edited for content, and, most importantly, has not undergone peer review. With the agreement of the associate editors and the AALAS leadership, I elected to forego peer review of this work, in contradiction to standard JAALAS policy, based on the status of this material as pre-published information from an affiliate organization that holds the copyright and on the esteem in which we hold for Dr. Brewer as a founding father of our organization.

  • The Distinctive Theropod Assemblage of the Ellisdale Site of New Jersey and Its Implications for North American Dinosaur Ecology and Evolution During the Cretaceous

Brownstein Stamford Museum and Nature Center, Stamford CT 〈[email protected]〉 Abstract.—The Cretaceous landmass of Appalachia has preserved an understudied but nevertheless important record of dinosaurs that has recently come under some attention. In the past few years, the vertebrate faunas of several Appalachian sites have been described. One such locality, the Ellisdale site of the Cretaceous Marshalltown Forma- tion of New Jersey, has produced hundreds of remains assignable to dinosaurs, including those of hadrosauroids of several size classes, indeterminate ornithopods, indeterminate theropods, the teeth, cranial, and appendicular elements of dromaeosaurids, ornithomimosaurians, and tyrannosauroids, and an extensive microvertebrate assemblage. The theropod dinosaur record of the Ellisdale site is currently the most extensive and diverse known from the Campanian of Appalachia. Study of the Ellisdale theropod specimens suggests that at

In order to determine the normal stages of formation in the sequence of ossification of the cranium of Podocnemis expansa in its various stages of development, embryos were collected starting on the 18th day of natural incubation and were subjected to bone diaphanization and staining. In the neurocranium, the basisphenoid and basioccipital bones present ossification centers in stage 19, the supraoccipital and opisthotic in stage 20, the exoccipital in stage 21, and lastly the prooptic in stage 24. Dermatocranium: the squamosal, pterygoid and maxilla are the first elements to begin the ossification process, which occurs in stage 16.

  • A New Origin for the Maxillary Jaw
    Developmental Biology 276 (2004) 207–224 www.elsevier.com/locate/ydbio A new origin for the maxillary jaw Sang-Hwy Leea, Olivier Be´dardb,1, Marcela Buchtova´b, Katherine Fub, Joy M. Richmanb,* aDepartment of Oral, Maxillofacial Surgery and Oral Science Research Center, Medical Science and Engineering Research Center, BK 21 Project for Medical Science, College of Dentistry Yonsei University, Seoul, Korea bDepartment of Oral Health Sciences, Faculty of Dentistry, University of British Columbia, Vancouver, BC, Canada, V6T 1Z3 Received for publication 7 April 2004, revised 5 August 2004, accepted 31 August 2004 Available online 5 October 2004 Abstract One conserved feature of craniofacial development is that the first pharyngeal arch has two components, the maxillary and mandibular, which then form the upper and lower jaws, respectively. However, until now, there have been no tests of whether the maxillary cells originate entirely within the first pharyngeal arch or whether they originate in a separate condensation, cranial to the first arch. We therefore constructed a fate map of the pharyngeal arches and environs with a series of dye injections into stage 13–17 chicken embryos. We found that from the earliest stage examined, the major contribution to the maxillary bud is from post-optic mesenchyme with a relatively minor contribution from the maxillo-mandibular cleft. Cells labeled within the first pharyngeal arch contributed exclusively to the mandibular prominence. Gene expression data showed that there were different molecular codes for the cranial and caudal maxillary prominence. Two of the genes examined, Rarb (retinoic acid receptor b) and Bmp4 (bone morphogenetic protein) were expressed in the post-optic mesenchyme and epithelium prior to formation of the maxillary prominence and then were restricted to the cranial half of the maxillary prominence.

SERENO Department of Organismal Biology and Anatomy and Committee on Evolutionary Biology, University of Chicago, 1027 East 57th Street, Chicago, Illinois, 60637, U.S.A. [email protected] Abstract . A new genus and species of ornithomimosaur, Afromimus tenerensis , is described based on a fragmentary skeleton from the Lower Cretaceous (Aptian–Albian) El Rhaz Formation of Niger. The holotype and only known individual preserves caudal vertebrae, chevrons and por - tions of the right hind limb. Derived ornithomimosaurian features include the broad, peanut-shaped articular surfaces of mid caudal centra, parasagittal fossae on mid caudal centra for reception of the postzygapophyses of the preceding vertebra, and a raised, subtriangular platform on the ventral aspect of the pedal phalanges.

    Dinosaur Genera List Page 1 of 42 You are visitor number— Zales Jewelry —as of November 7, 2008 The Dinosaur Genera List became a standalone website on December 4, 2000 on America Online’s Hometown domain. AOL closed the domain down on Halloween, 2008, so the List was carried over to the www.polychora.com domain in early November, 2008. The final visitor count before AOL Hometown was closed down was 93661, on October 30, 2008. List last updated 12/15/17 Additions and corrections entered since the last update are in green.

Search for “paleontology.” Unfortunately, as of May 2011, Adobe changed its PDF-creation website and no longer supports making PDFs directly from HTML files. I finally figured out a way around this problem, but the PDF no longer preserves background colors, such as the green backgrounds in the genera counts. Win some, lose some.
