And the Origin and Evolution of the Ankylosaur Pelvis
Pelvis of Gargoyleosaurus (Dinosauria: Ankylosauria) and the Origin and Evolution of the Ankylosaur Pelvis Kenneth Carpenter1,2*, Tony DiCroce3, Billy Kinneer3, Robert Simon4 1 Prehistoric Museum, Utah State University – Eastern, Price, Utah, United States of America, 2 Geology Section, University of Colorado Museum, Boulder, Colorado, United States of America, 3 Denver Museum of Nature and Science, Denver, Colorado, United States of America, 4 Dinosaur Safaris Inc., Ashland, Virginia, United States of America Abstract Discovery of a pelvis attributed to the Late Jurassic armor-plated dinosaur Gargoyleosaurus sheds new light on the origin of the peculiar non-vertical, broad, flaring pelvis of ankylosaurs. It further substantiates separation of the two ankylosaurs from the Morrison Formation of the western United States, Gargoyleosaurus and Mymoorapelta. Although horizontally oriented and lacking the medial curve of the preacetabular process seen in Mymoorapelta, the new ilium shows little of the lateral flaring seen in the pelvis of Cretaceous ankylosaurs. Comparison with the basal thyreophoran Scelidosaurus demonstrates that the ilium in ankylosaurs did not develop entirely by lateral rotation as is commonly believed. Rather, the preacetabular process rotated medially and ventrally and the postacetabular process rotated in opposition, i.e., lateral and ventrally. Thus, the dorsal surfaces of the preacetabular and postacetabular processes are not homologous. In contrast, a series of juvenile Stegosaurus ilia show that the postacetabular process rotated dorsally ontogenetically. Thus, the pelvis of the two major types of Thyreophora most likely developed independently. Examination of other ornithischians show that a non-vertical ilium had developed independently in several different lineages, including ceratopsids, pachycephalosaurs, and iguanodonts.

Taxonomically assigned to numerous groups since discovery, 25in 1981 it was described as a stegosaur, a group of armoured ornithischian dinosaurs 26characterised by bizarre plates and spines extending from the neck to the tail. This assignment 27that has been subsequently accepted. The type material consists of a premaxilla, maxilla, a nasal, 28and a vertebra, and contains no synapomorphies of Stegosauria. Several features of the maxilla 29and dentition are reminiscent of Ankylosauria, the sister-taxon to Stegosauria, and the premaxilla 30appears superficially similar to that of some ornithopods. The vertebral material has never been 31described, and since the last description of the specimen, there have been numerous discoveries 32of thyreophoran material potentially pertinent to establishing the taxonomic assignment of the 33specimen. An investigation of the taxonomic and systematic position of Paranthodon is therefore 34warranted. This study provides a detailed re-description, including the first description of the 35vertebra. Numerous phylogenetic analyses demonstrate that the systematic position of 36Paranthodon is highly labile and subject to change depending on which exemplifier for the clade 37Stegosauria is used.

A Census of Dinosaur Fossils Recovered from the Hell Creek and Lance Formations (Maastrichtian)
The Journal of Paleontological Sciences: JPS.C.2019.01 1 TAKING COUNT: A Census of Dinosaur Fossils Recovered From the Hell Creek and Lance Formations (Maastrichtian). ______________________________________________________________________________________ Walter W. Stein- President, PaleoAdventures 1432 Mill St.. Belle Fourche, SD 57717. [email protected] 605-210-1275 ABSTRACT: A census of Hell Creek and Lance Formation dinosaur remains was conducted from April, 2017 through February of 2018. Online databases were reviewed and curators and collections managers interviewed in an effort to determine how much material had been collected over the past 130+ years of exploration. The results of this new census has led to numerous observations regarding the quantity, quality, and locations of the total collection, as well as ancillary data on the faunal diversity and density of Late Cretaceous dinosaur populations. By reviewing the available data, it was also possible to make general observations regarding the current state of certain exploration programs, the nature of collection bias present in those collections and the availability of today's online databases. A total of 653 distinct, associated and/or articulated remains (skulls and partial skeletons) were located. Ceratopsid skulls and partial skeletons (mostly identified as Triceratops) were the most numerous, tallying over 335+ specimens. Hadrosaurids (Edmontosaurus) were second with at least 149 associated and/or articulated remains. Tyrannosaurids (Tyrannosaurus and Nanotyrannus) were third with a total of 71 associated and/or articulated specimens currently known to exist. Basal ornithopods (Thescelosaurus) were also well represented by at least 42 known associated and/or articulated remains. The remaining associated and/or articulated specimens, included pachycephalosaurids (18), ankylosaurids (6) nodosaurids (6), ornithomimids (13), oviraptorosaurids (9), dromaeosaurids (1) and troodontids (1).

Competition Structured a Late Cretaceous Megaherbivorous Dinosaur Assemblage Jordan C
www.nature.com/scientificreports OPEN Competition structured a Late Cretaceous megaherbivorous dinosaur assemblage Jordan C. Mallon 1,2 Modern megaherbivore community richness is limited by bottom-up controls, such as resource limitation and resultant dietary competition. However, the extent to which these same controls impacted the richness of fossil megaherbivore communities is poorly understood. The present study investigates the matter with reference to the megaherbivorous dinosaur assemblage from the middle to upper Campanian Dinosaur Park Formation of Alberta, Canada. Using a meta-analysis of 21 ecomorphological variables measured across 14 genera, contemporaneous taxa are demonstrably well-separated in ecomorphospace at the family/subfamily level. Moreover, this pattern is persistent through the approximately 1.5 Myr timespan of the formation, despite continual species turnover, indicative of underlying structural principles imposed by long-term ecological competition. After considering the implications of ecomorphology for megaherbivorous dinosaur diet, it is concluded that competition structured comparable megaherbivorous dinosaur communities throughout the Late Cretaceous of western North America. Te question of which mechanisms regulate species coexistence is fundamental to understanding the evolution of biodiversity1. Te standing diversity (richness) of extant megaherbivore (herbivores weighing ≥1,000 kg) com- munities appears to be mainly regulated by bottom-up controls2–4 as these animals are virtually invulnerable to top-down down processes (e.g., predation) when fully grown. Tus, while the young may occasionally succumb to predation, fully-grown African elephants (Loxodonta africana), rhinoceroses (Ceratotherium simum and Diceros bicornis), hippopotamuses (Hippopotamus amphibius), and girafes (Girafa camelopardalis) are rarely targeted by predators, and ofen show indiference to their presence in the wild5.

They were much bigger than lots of animals that are alive today. Some dinosaurs were 40 feet high! There were lots of different types of dinosaurs too. Some were big and other were small. Some had scales like a lizard and others had feathers like a bird. Some dinosaurs walked, ran, and crawled, and other dinosaurs swam deep in the ocean. There were so many dinosaurs that scientists are still finding dinosaur fossils today! Today’s fun includes an eye spy, an activity to create your own dinosaur, and a matching game!

NEW DATA on the SKULL of PINACOSAURUS Grangerl (ANK YLOSAURIA)
TER ESA MAR YANSKA NEW DATA ON THE SKULL OF PINACOSAURUS GRANGERl (ANK YLOSAURIA) (Plate s VI-VII) Abstract. - Th e skull of a young indiv idual of Pinacosaurus grangcri G ILMORE from the Upper Cretaceo us sandstone of Bayn Dz ak in the Gobi Desert, Mongolia, has been prelim inaril y described. Tabul ars, post front als, ossified conchae, septurn nasi and three pairs of nasal openings were found in the described skull. A postcrani al skeleton associated with the skull will be described in another pa per. INTRODUCTION Armoured dinosaurs were found by the Polish-Mongolian Palaeontological Expeditions in two regions of Gobi Desert : in the Nemegt Basin (MARYANSKA , 1970) in the Uppermost Cretaceous sandstone and at Bayn Dzak in the Upper Cretaceous sand ston e (recognized as Coniacian or Santonian by KIELA N-JAWOR OWSKA(1970) on the basis of mult ituberculate faun a). The present paper is a preliminary report on ankyl osaurid remains found by the Polish-Mon golian Expedition in 1964 at Bayn Dzak. The collection from this locality con sists of an almost complete skeleton with an excellently preserved skull (Z. Pal. No. MgD-f1/1), as well as several skeletal fragments of another specimen, including a pelvic girdle, hind limbs and a tail (Z.Pal. No. MgD-II/9). Those two specimens come from stratigra phic horizon, designated by GRA DZI NSKI et al. (1968/69, pp. 70-71 , Text-fig. 30) by number ,,2". Skulls of multituberculate and eutherian mammals, described by KIELAN-JAWOROWSKA (1968/69 and 1970) were also taken from this horizon.

I would also like to thank the rest of my advisory committee; Dr. Richard Denne who I got to know well by taking many of his courses. In addition, Dr. Tom Lehman who acted as an outside committee member and has been with me since day one to my very first geology class at Texas Tech. He has been a mentor to me for almost six years and I hope that I become a paleontologist that makes him and Dr. Busbey proud. I would also like to thank the various museum staff members who hosted me on my research trips; Nicole Ridgewell who had two ankylosaur skulls already waiting for me when I arrived at the University of New Mexico and Chris Mehling at the American Museum of Natural History who put up with my constant emails and who helped me retrieve specimens from drawers when my back gave out. And especially Dr. Chris Sagebiel and Dr. Matthew Colbert and the staff at the Vertebrate Paleontology Lab in Austin, Tx who scanned the osteoderm specimens for me. Finally, I would like to thank my family for their unwavering support.

How Dinosaurs Looked
Fossilized Fashion: How Dinosaurs Looked Fancy frills, sharp horns, pointy spikes, massive sails on their backs—dinosaurs had them all! The question is: Why did dinosaurs sport these far-out features? For clues, scientists often compare dinosaur designs with those of modern animals. Check out this album of animal fashions. Try to guess what the features are for! 1. What is the function of the armor on these animals?
