However, the phylogeny of basal ceratopsians remains unclear. Here we report a new basal neoceratopsian dinosaur Beg tse based on a partial skull from Baruunbayan, Ömnögovi aimag, Mongolia. Beg is diagnosed by a unique combination of primitive and derived characters including a primitively deep premaxilla with four pre- maxillary teeth, a trapezoidal antorbital fossa with a poorly delineated anterior margin, very short dentary with an expanded and shallow groove on lateral surface, the derived presence of a robust jugal having a foramen on its anteromedial surface, and five equally spaced tubercles on the lateral ridge of the surangular. This is to our knowledge the earliest known occurrence of basal neoceratopsian in Mongolia, where this group was previously only known from Late Cretaceous strata. Phylogenetic analysis indicates that it is sister to all other neoceratopsian dinosaurs. 1 Division of Vertebrate Paleontology, American Museum of Natural History, New York 10024, USA. 2 Institut Català de Paleontologia Miquel Crusafont, ICTA-ICP, Edifici Z, c/de les Columnes s/n Campus de la Universitat Autònoma de Barcelona, 08193 Cerdanyola del Vallès Sabadell, Barcelona, Spain. 3 Department of Biological Sciences, North Carolina State University, Raleigh, NC 27695, USA. 4 Institute of Paleontology, Mongolian Academy of Sciences, ✉ Ulaanbaatar 15160, Mongolia.

A review of studies of sexual dimorphism in the vertebrate fossil record revealed methods that were selected for use in ceratopsids. Mountain goats, bison, and pronghorn were selected as exemplar taxa for a proof of principle study that tested the selected methods, and informed and guided the investigation of sexual dimorphism in dinosaurs. Skulls of these exemplar taxa were measured in museum collections, and methods of analysing morphological variation were tested for their ability to demonstrate sexual dimorphism in their horns and horncores.

  • Histology and Ontogeny of Pachyrhinosaurus Nasal Bosses By
    Histology and Ontogeny of Pachyrhinosaurus Nasal Bosses by Elizabeth Kruk A thesis submitted in partial fulfillment of the requirements for the degree of Master of Science in Systematics and Evolution Department of Biological Sciences University of Alberta © Elizabeth Kruk, 2015 Abstract Pachyrhinosaurus is a peculiar ceratopsian known only from Upper Cretaceous strata of Alberta and the North Slope of Alaska. The genus consists of three described species Pachyrhinosaurus canadensis, Pachyrhinosaurus lakustai, and Pachyrhinosaurus perotorum that are distinguishable by cranial characteristics, including parietal horn shape and orientation, absence/presence of a rostral comb, median parietal bar horns, and profile of the nasal boss. A fourth species of Pachyrhinosaurus is described herein and placed into its phylogenetic context within Centrosaurinae. This new species forms a polytomy at the crown with Pachyrhinosaurus canadensis and Pachyrhinosaurus perotorum, with Pachyrhinosaurus lakustai falling basal to that polytomy. The diagnostic features of this new species are an apomorphic, laterally curved Process 3 horns and a thick longitudinal ridge separating the supraorbital bosses. Another focus is investigating the ontogeny of Pachyrhinosaurus nasal bosses in a histological context. Previously, little work has been done on cranial histology in ceratopsians, focusing instead on potential integumentary structures, the parietals of Triceratops, and how surface texture relates to underlying histological structures. An ontogenetic series is established for the nasal bosses of Pachyrhinosaurus at both relative (subadult versus adult) and fine scale (Stages 1-5). It was demonstrated that histology alone can indicate relative ontogenetic level, but not stages of a finer scale. Through Pachyrhinosaurus ontogeny the nasal boss undergoes increased vascularity and secondary remodeling with a reduction in osteocyte lacunar density.

  • Rocky Start of Dinosaur National Monument (USA), the World's First Dinosaur Geoconservation Site
    Original Article Rocky Start of Dinosaur National Monument (USA), the World's First Dinosaur Geoconservation Site Kenneth Carpenter Prehistoric Museum, Utah State University Eastern Price, Utah 80504 USA Abstract The quarry museum at Dinosaur National Monument, which straddles the border between the American states of Colorado and Utah, is the classic geoconservation site where visitors can see real dinosaur bones embedded in rock and protected from the weather by a concrete and glass structure. The site was found by the Carnegie Museum in August 1909 and became a geotourist site within days of its discovery. Within a decade, visitors from as far as New Zealand traveled the rough, deeply rutted dirt roads to see dinosaur bones in the ground for themselves. Fearing that the site would be taken over by others, the Carnegie Museum attempted twice to take the legal possession of the land. The second attempt had consequences far beyond what the Museum intended when the federal government declared the site as Dinosaur National Monument in 1915, thus taking ultimate control from the Carnegie Museum. Historical records and other archival data (correspondence, diaries, reports, newspapers, hand drawn maps, etc.) are used to show that the unfolding of events was anything but smooth. It was marked by misunderstanding, conflicting Corresponding Author: goals, impatience, covetousness, miscommunication, unrealistic expectation, intrigue, and some Kenneth Carpenter paranoia, which came together in unexpected ways for both the Carnegie Museum and the federal Utah State University Eastern Price, government.

Brown1,*, Robert B. Holmes2, Philip J. Currie2 1Royal Tyrrell Museum of Palaeontology, Box 7500, Drumheller, AB, T0J 0Y0, Canada; [email protected] 2Department of Biological Sciences, University of Alberta, Edmonton, Alberta, T6G 2E9, Canada; [email protected]; [email protected] Abstract: Styracosaurus albertensis is an iconic centrosaurine horned dinosaur from the Campanian of Alberta, Canada, known for its large spike-like parietal processes. Although described over 100 years ago, subsequent dis- coveries were rare until the last few decades, during which time several new skulls, skeletons, and bonebeds were found. Here we described an immature individual, the smallest known for the species, represented by a complete skull and fragmentary skeleton. Although ~80% maximum size, it possesses a suite of characters associated with immaturity, and is regarded as a subadult. The ornamentation is characterized by a small, recurved, but fused nasal horncore; short, rounded postorbital horncores; and short, triangular, and flat parietal processes. Using this specimen, and additional skulls and bonebed material, the cranial ontogeny of Styracosaurus is described, and compared to Centrosaurus. In early ontogeny, the nasal horncores of Styracosaurus and Centrosaurus are thin, recurved, and unfused, but in the former the recurved morphology is retained into large adult size and the horncore never develops the procurved morphology common in Centrosaurus. The postorbital horncores of Styracosaurus are shorter and more rounded than those of Centrosaurus throughout ontogeny, and show great- er resorption later in ontogeny.

  • A New Maastrichtian Species of the Centrosaurine Ceratopsid Pachyrhinosaurus from the North Slope of Alaska
    A new Maastrichtian species of the centrosaurine ceratopsid Pachyrhinosaurus from the North Slope of Alaska ANTHONY R. FIORILLO and RONALD S. TYKOSKI Fiorillo, A.R. and Tykoski, R.S. 2012. A new Maastrichtian species of the centrosaurine ceratopsid Pachyrhinosaurus from the North Slope of Alaska. Acta Palaeontologica Polonica 57 (3): 561–573. The Cretaceous rocks of the Prince Creek Formation contain the richest record of polar dinosaurs found anywhere in the world. Here we describe a new species of horned dinosaur, Pachyrhinosaurus perotorum that exhibits an apomorphic character in the frill, as well as a unique combination of other characters. Phylogenetic analysis of 16 taxa of ceratopsians failed to resolve relationships between P. perotorum and other Pachyrhinosaurus species (P. canadensis and P. lakustai). P. perotorum shares characters with each of the previously known species that are not present in the other, including very large nasal and supraorbital bosses that are nearly in contact and separated only by a narrow groove as in P. canadensis, and a rostral comb formed by the nasals and premaxillae as in P. lakustai. P. perotorum is the youngest centrosaurine known (70–69 Ma), and the locality that produced the taxon, the Kikak−Tegoseak Quarry, is close to the highest latitude for recovery of ceratopsid remains.

  • 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.

  • New Evidence for Combat and Cannibalism in Tyrannosaurs 9 April 2015
    New evidence for combat and cannibalism in tyrannosaurs 9 April 2015 Researchers found numerous injuries on the skull that occurred during life. Although not all of them can be attributed to bites, several are close in shape to the teeth of tyrannosaurs. In particular one bite to the back of the head had broken off part of the skull and left a circular tooth-shaped puncture though the bone. The fact that alterations to the bone's surface indicate healing means that these injuries were not fatal and the animal lived for some time after they were inflicted. Lead author Dr David Hone from Queen Mary, University of London said "This animal clearly had a tough life suffering numerous injuries across the head including some that must have been quite nasty. The most likely candidate to have done this Artist's reconstruction of one Daspletosaurus feeding on another.
