Astragalar Morphology of Selected Giraffidae
RESEARCH ARTICLE Astragalar Morphology of Selected Giraffidae Nikos Solounias1,2☯*, Melinda Danowitz1☯ 1 Department of Anatomy, New York Institute of Technology College of Osteopathic Medicine, Old Westbury, NY, United States of America, 2 Department of Paleontology, American Museum of Natural History, Central Park West at 79th Street, New York, NY, United States of America ☯ These authors contributed equally to this work. * [email protected] Abstract The artiodactyl astragalus has been modified to exhibit two trochleae, creating a double pullied structure allowing for significant dorso-plantar motion, and limited mediolateral motion. The astragalus structure is partly influenced by environmental substrates, and cor- respondingly, morphometric studies can yield paleohabitat information. The present study establishes terminology and describes detailed morphological features on giraffid astragali. Each giraffid astragalus exhibits a unique combination of anatomical characteristics. The giraffid astragalar morphologies reinforce previously established phylogenetic relationships. We find that the enlargement of the navicular head is a feature shared by all giraffids, and that the primitive giraffids possess exceptionally tall astragalar heads in relation to the total astragalar height. The sivatheres and the okapi share a reduced notch on the lateral edge OPEN ACCESS of the astragalus. We find that Samotherium is more primitive in astragalar morphologies Citation: Solounias N, Danowitz M (2016) Astragalar than Palaeotragus, which is reinforced -
Original Giraffokeryx Punjabiensis (Artiodactyla, Ruminantia, Giraffidae) from Lower Siwaliks (Chinji Formation) of Dhok Bun
Original Giraffokeryx punjabiensis (Artiodactyla, Ruminantia, Giraffidae) from Lower Siwaliks (Chinji Formation) of Dhok Bun Ameer Khatoon, Pakistan Khizar Samiullah1*, Muhammad Akhtar2, Abdul Ghaffar3, Muhammad Akbar Khan4 Received : 28 January 2011 ; Accepted : 13 September 2011 Abstract Fossil remains of Giraffokeryx punjabiensis (premolar and molar teeth belonging to the upper and lower jaws) have been collected and discussed from Chinji Formation of Dhok Bun Ameer Khatoon (32o 47’ 26.4” N, 72° 55’ 35.7” E). All these (twenty one) specimens are isolated teeth, which provide new data and give valuable information on the biostratigrphy and paleoecology of Giraffokeryx punjabiensis as well as the stratigraphy and paleoclimates of these Miocene rocks of the Chakwal district, Pakistan. Keywords: Giraffokeryx punjabiensis, isolated teeth, Chinji Formation, biostratigraphy Miocene rocks, Chakwal district. Introduction Dhok Bun Ameer Khatoon (DBAK) is poorly known fossil ramii and a number of isolated teeth. Mathew4 studied site of the Siwaliks. Previous pioneer workers 1,2,3,4,5 did the material of this species at the Indian Museum, not visit this site nor mentioned it in their faunal list.

AMERICAN MUSEUM NOVITATES Published by Tnui AmERMICAN MUSZUM W Number 632 Near York CityRATt1RAL HisToRay June 9, 1933 56.9, 735 G: 14.71, 4 A SKULL AND MANDIBLE OF GIRAFFOKERYX PUNJABIENSIS PILGRIM By EDWIN H. COLBERT The genus Giraffokeryx was founded by Dr. G. E. Pilgrim to desig- nate a primitive Miocene giraffe from the lower Siwalik beds of northern India. Doctor Pilgrim, in a series of papers,' described Giraffokeryx on the basis of fragmental and scattered dentitions.. Naturally, Pilgrim's knowledge of the genus was rather incomplete, and he was unable tQ formulate any opinions as to the structure.of the skull or mandible. An almost complete skull, found in the northern Punjab in 1922 by Mr. Barnum Brown of the American Museum, proves to be that of Giraffokeryx, and it exhibits such striking and unusual characters that a separate description of it has seemed necessary. This skull, together with numerous teeth and a lower. jaw, gives us. a very good comprehen- sion of the genus which forms the subject.of this paper. The drawings of the skull were made by John. C. Germann, and the remaining ones were done by Margaret Matthew. MATERIAL DESCRIBED Only the material referred to in this description will here be listed. There' are a great many specimens of Gir'affokeryx in the American'Mu- seum collection, but since 'most of them are'teeth, they will not be considered at this time. A subsequent paper, dealing with the American Museum Siwalik collection in detail, wtyill contain a complete list of the Giraffokeryx material. -

Khan and 3Abdul Ghaffar 1Zoology department, Quaid-e-Azam campus, Punjab University, Lahore, Punjab, Pakistan 2Zoology Department, GC University, Faisalabad, Punjab, Pakistan 3Department of Meteorology, COMSATS Institute of Information Technology (CIIT), Islamabad ABSTRACT Fossil site Dhok Bun Ameer Khatoon (32o 47' 26.4" N, 72° 55' 35.7" E) yielded a significant amount of mammalian assemblage including two families of even-toed fossil mammal (Giraffidae, and Bovidae) and one family of odd-toed (Rhinocerotidae) of the Late Miocene (Samiullah, 2011). This newly discovered site has well exposed Chinji and Nagri formation and has dated approximately 14.2-9.5 Ma. This age agrees with the divergence of different mammalian genera. Sedimentological evidence of the site supports that this is deposited in locustrine or fluvial environment, as Chinji formation is composed primarily of mud-stone while the Nagri formation is sand dominated. Palaeoenvironmental data indicates that Miocene climate of Pakistan was probably be monsoonal as there is now a days. Mostly the genera recovered from this site resemble with the overlying younger Dhok Pathan formation of the Siwaliks while the size variation in dentition is taxonomically important for vertebrate evolutionary point of view and this is the main reason to conduct this study at this specific site to add additional information in the field of Palaeontology. A detailed study of fossils mammals found in Miocene rocks exposed at Dhok Bun Ameer Khatoon was carried out. -

The comparison of the material was made with several Siwalik representatives of the giraffids. The giraffid Sivatherium is a gigantic giraffid found in the early Pleistocene sediments of the Upper Siwaliks. The village Sardhok locality has yielded one of the best collections of Giraffidae from the early Pleistocene of the Siwaliks. The locality belongs to the Pinjor Formation of the Upper Siwaliks (2.6-0.6 Ma). Key words: Giraffids, Sivatherium, Upper Siwaliks, Pleistocene, Pinjor Formation. INTRODUCTION The material described here comes from the outcrops of the village Sardhok, Gujrat district, Punjab, The fossil Chinese record shown by Bohlin Pakistan. In the Potwar Plateau, the Upper Siwalik is well (1927) and that of Asia shown by Colbert (1935) exposed in the Pabbi hills situated in the east of the River indicates that the giraffids had their origin in the Jhelum. The village Sardhok is situated in these low Holarctic Region. -

Akhtar2 1 Zoology Department, GC University, Lahore, Punjab, Pakistan 2 Dr. Abu Bakr Fossil Display and Research Centre, Zoology Department, Quid-e-Azam Campus, University of the Punjab, Lahore, Punjab, Pakistan Corresponding author Email: [email protected] ABSTRACT New remains of Giraffa priscilla are recorded from the Middle Miocene localities of Pakistan. The material originates from Chinji Rest House, Rakh Wasnal, Dhok Bun Amir Khatoon, Dhulian, Ghungrilla, Dial, Lava, Phadial, Bhelomar and Ratial. These localities are also well known for the rich Middle Miocene mammalian fauna of the Siwaliks. The estimated age of these localities is 14.2–11.2 Ma, belonging to the Chinji Formation of the Lower Siwaliks. The findings contribute to our understanding of the presence of this species in the Middle Miocene of Pakistan. Key words: Mammalia, Vertebrates, Giraffa priscilla, Miocene, Siwaliks.

October 2015 ii Acknowledgements Including a list of people to whom I am grateful to in the acknowledgement section hardly does justice to the respective persons: A thesis is, in all honestly, only comprehensively read by very few people. Nevertheless, it occurred to me that even when I roughly skim through a thesis or dissertation for bits of information, I am always drawn into the acknowledgements. I suppose it is the only section where one can get a glimpse into the life of the researcher in an otherwise rather ‘cold’ academic work. Therefore, although not a large platform to say ‘thank you’, I wish to convey to everyone listed here that you are in the warmest part of my heart … and probably the most read part of my thesis. Prof Graham Mitchell for his patience with me, his guidance, enthusiasm and confidence. I consider myself lucky and honoured to have had you as a supervisor. -
I.—A Retrospect of Palaeontology in the Last Forty Years

EEPTILIA ET AVES.—Our two greatest Anatomists of the past century, Owen and Huxley, both contributed to this section of our palseozoological record. Owen (in 1865) described some remains of a small air-breathing vertebrate, Anihrakerpeton crassosteum, from the Coal-shales of Glamorganshire, corresponding with those described by Dawson from the Coal-measures of Nova Scotia ; and in 1870 he noticed some remains of Plesiosaurus Hoodii (Owen) from New Zealand, possibly of Triaasic age. Huxley made us acquainted with an armed Dinosaur from the Chalk-marl of Folkestone, allied to Scelidosaurus (Liassic), ITylao- saurus and Polacanthus (Wealden), the teeth and dermal spines of which he described and figured (1867), and in the following year he figured and determined two new genera of Triassic reptilia, Saurosternon Bainii and Pristerodon McKayi, from the Dicynodont beds of South Africa. E. Etheridge recorded (in 1866) the discovery by Dr. E. P. Wright and Mr. Brownrig of several new genera of Labyrinthodonts in the Coal-shales of Jarrow Colliery, Kilkenny, Ireland, com- municated by Huxley to the Royal Irish Academy, an account of which appeared later on in the GEOLOGICAL MAGAZINE in the same year by Dr. E. P. Wright (p. 165), the genera given being Urocordylus, Ophiderpeton, Ichthyerpeton, Keraterpeton, Lepterpeton, and Anthracosaurus. Besides these genera there were indications of the existence of several others (not described), making at that time a total of thirteen genera from the Carboniferous formation in general.
