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. -

The new taxon, Linheraptor exquisitus gen. et sp. nov., is based on an exceptionally well-preserved, nearly complete skeleton. This specimen represents the fifth dromaeosaurid taxon recovered from the Upper Cretaceous Djadokhta Formation and its laterally equivalent strata, which include the Wulansuhai Formation, and adds to the known diversity of Late Cretaceous dromaeosaurids. Linheraptor exquisitus closely resembles the recently reported Tsaagan mangas. Uniquely among dromaeosaurids, the two taxa share a large, anteriorly located maxillary fenestra and a contact between the jugal and the squamosal that excludes the postorbital from the infratemporal fenestra. -

Chapter 10, the Mistaken Extinction, by Lowell Dingus and Timothy Rowe, New York, W
Chapter 10, The Mistaken Extinction, by Lowell Dingus and Timothy Rowe, New York, W. H. Freeman, 1998. CHAPTER 10 Dinosaurs Challenge Evolution Enter Sir Richard Owen More than 150 years ago, the great British naturalist Richard Owen (fig. 10.01) ignited the controversy that Deinonychus would eventually inflame. The word "dinosaur" was first uttered by Owen in a lecture delivered at Plymouth, England in July of 1841. He had coined the name in a report on giant fossil reptiles that were discovered in England earlier in the century. The root, Deinos, is usually translated as "terrible" but in his report, published in 1842, Owen chose the words "fearfully great"1. To Owen, dinosaurs were the fearfully great saurian reptiles, known only from fossil skeletons of huge extinct animals, unlike anything alive today. Fig. 10.01 Richard Owen as, A) a young man at about the time he named Dinosauria, B) in middle age, near the time he described Archaeopteryx, and C) in old age. Dinosaur bones were discovered long before Owen first spoke their name, but no one understood what they represented. The first scientific report on a dinosaur bone belonging was printed in 1677 by Rev. Robert Plot in his work, The Natural History of Oxfordshire. This broken end of a thigh bone, came to Plot's attention during his research. It was nearly 60 cm in circumference--greater than the same bone in an elephant (fig.10.02). We now suspect that it belonged to Megalosaurus bucklandii, a carnivorous dinosaur now known from Oxfordshire. But Plot concluded that it "must have been a real Bone, now petrified" and that it resembled "exactly the figure of the 1 Chapter 10, The Mistaken Extinction, by Lowell Dingus and Timothy Rowe, New York, W. -
New Perspectives on Pterosaur Palaeobiology
Downloaded from http://sp.lyellcollection.org/ by guest on September 24, 2021 New perspectives on pterosaur palaeobiology DAVID W. E. HONE1*, MARK P. WITTON2 & DAVID M. MARTILL2 1Queen Mary University of London, Mile End Road, London E14NS, UK 2School of Earth and Environmental Sciences, University of Portsmouth, Burnaby Road, Portsmouth PO1 3QL, UK *Correspondence: [email protected] Abstract: Pterosaurs were the first vertebrates to evolve powered flight and occupied the skies of the Mesozoic for 160 million years. They occurred on every continent, evolved their incredible pro- portions and anatomy into well over 100 species, and included the largest flying animals of all time among their ranks. Pterosaurs are undergoing a long-running scientific renaissance that has seen elevated interest from a new generation of palaeontologists, contributions from scientists working all over the world and major advances in our understanding of their palaeobiology. They have espe- cially benefited from the application of new investigative techniques applied to historical speci- mens and the discovery of new material, including detailed insights into their fragile skeletons and their soft tissue anatomy. Many aspects of pterosaur science remain controversial, mainly due to the investigative challenges presented by their fragmentary, fragile fossils and notoriously patchy fossil record. With perseverance, these controversies are being resolved and our understand- ing of flying reptiles is increasing. This volume brings together a diverse set of papers on numerous aspects of the biology of these fascinating reptiles, including discussions of pterosaur ecology, flight, ontogeny, bony and soft tissue anatomy, distribution and evolution, as well as revisions of their taxonomy and relationships. -

Phylogeny and Avian Evolution Phylogeny and Evolution of the Aves I. Background Scientists have speculated about evolution of birds ever since Darwin. Difficult to find relatives using only modern animals After publi cati on of “O rigi i in of S peci es” (~1860) some used birds as a counter-argument since th ere were no k nown t ransiti onal f orms at the time! • turtles have modified necks and toothless beaks • bats fly and are warm blooded With fossil discovery other potential relationships! • Birds as distinct order of reptiles Many non-reptilian characteristics (e.g. endothermy, feathers) but really reptilian in structure!
