A large hadro- saurid dinosaur from Presa San Antonio, Cerro del Pueblo Formation, Coahuila, Mexico. Acta Palae onto logica Polonica 66 (Supplement to x): xxx–xxx. New hadrosaurid postcranial material is reported, collected near Presa San Antonio, Parras de la Fuente municipality, Coahuila, Mexico, in a sedimentary sequence belonging to the upper Campanian of the Cerro del Pueblo Formation, in the Parras Basin. The skeletal remains include partial elements from the pelvic girdle (left ilium, right pubis, ischium, and incomplete sacrum), a distal end of a left femur, almost complete right and left tibiae, right metatarsals II and IV, cervical and caudal vertebrae. Also, partially complete forelimb elements are present, which are still under preparation. The pubis shows characters of the Lambeosaurinae morphotypes, but the lack of cranial elements does not allow us to directly differentiate this specimen from the already described hadrosaurid taxa from the studied area, such as Velafrons coahuilensis, Latirhinus uitstlani, and Kritosaurus navajovius. This specimen, referred as Lambeosaurinae indet., adds to the fossil record of the hadrosaurids in southern Laramidia during the Campanian. Key words: Dinosauria, Hadrosauridae, Lambeosaurinae, Cretaceous, Campanian, Mexico. Rogelio Antonio Reyna-Hernández [[email protected]], Luis E.

An isolated track and a trackway are located within the upper member at the Cockscomb, and an isolated track is in the capping sandstone member at Wesses Canyon. The upper member tracks are tridactyl pes imprints consisting of a longer, blunt digit III and shorter, blunt digits II-IV. This trace corresponds well to an ornithropod dinosaur as the trackmaker. The capping sandstone member track is a tridactyl pes with an elongate digit III and shorter digits II-IV. Claw impressions are present on the terminus of digits II and III. This trace is consistent with the pes impression of a one meter tall theropod. The tracks further highlight the diversity of dinosaurs in the capping sandstone of the Wahweap Formation. INTRODUCTION During the Late Cretaceous, North America, in particular the west- ern United States, was the site of a radiation of new dinosaurian genera.

  • 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.

  • A Tyrannosauroid Metatarsus from the Merchantville Formation of Delaware Increases the Diversity of Non-Tyrannosaurid Tyrannosauroids on Appalachia
    A tyrannosauroid metatarsus from the Merchantville Formation of Delaware increases the diversity of non-tyrannosaurid tyrannosauroids on Appalachia Chase D. Brownstein Collections and Exhibitions, Stamford Museum & Nature Center, Stamford, CT, USA ABSTRACT During the Late Cretaceous, the continent of North America was divided into two sections: Laramidia in the west and Appalachia in the east. Although the sediments of Appalachia recorded only a sparse fossil record of dinosaurs, the dinosaur faunas of this landmass were different in composition from those of Laramidia. Represented by at least two taxa (Appalachiosaurus montgomeriensis and Dryptosaurus aquilunguis), partial and fragmentary skeletons, and isolated bones, the non-tyrannosaurid tyrannosauroids of the landmass have attracted some attention. Unfortunately, these eastern tyrants are poorly known compared to their western contemporaries. Here, one specimen, the partial metatarsus of a tyrannosauroid from the Campanian Merchantville Formation of Delaware, is described in detail. The specimen can be distinguished from A. montgomeriensis and D. aquilunguis by several morphological features. As such, the specimen represents a potentially previously unrecognized taxon of tyrannosauroid from Appalachia, increasing the diversity of the clade on the landmass. Phylogenetic analysis and the morphology of the bones suggest the Merchantville specimen is a tyrannosauroid of “intermediate” grade, thus supporting the notion that Appalachia was a refugium Submitted 18 July 2017 for relict dinosaur

Only two such giant “raptors” have been described from North America. Here, we describe a new giant dromaeosaurid, Dakotaraptor steini gen. et sp. nov., from the Hell Creek Formation of South Dakota. The discovery represents the first giant dromaeosaur from the Hell Creek Formation, and the most recent in the fossil record worldwide. A row of prominent ulnar papilli or “quill knobs” on the ulna is our first clear evidence for feather quills on a large dromaeosaurid forearm and impacts evolutionary reconstructions and functional morphology of such derived, typically flight-related features.

  • New Horned Dinosaurs from Utah Provide Evidence for Intracontinental Dinosaur Endemism
    New Horned Dinosaurs from Utah Provide Evidence for Intracontinental Dinosaur Endemism Scott D. Sampson1*, Mark A. Loewen1, Andrew A. Farke2, Eric M. Roberts3, Catherine A. Forster4, Joshua A. Smith1, Alan L. Titus5 1 Utah Museum of Natural History and Department of Geology and Geophysics, University of Utah, Salt Lake City, Utah, United States of America, 2 Raymond M. Alf Museum of Paleontology, Claremont, California, United States of America, 3 School of Earth and Environmental Science, James Cook University, Townsville, Queensland, Australia, 4 Department of Biological Sciences, George Washington University, Washington, D. C. United States of America, 5 Grand Staircase-Escalante National Monument, Bureau of Land Management, Kanab, Utah, United States of America Abstract Background: During much of the Late Cretaceous, a shallow, epeiric sea divided North America into eastern and western landmasses. The western landmass, known as Laramidia, although diminutive in size, witnessed a major evolutionary radiation of dinosaurs. Other than hadrosaurs (duck-billed dinosaurs), the most common dinosaurs were ceratopsids (large- bodied horned dinosaurs), currently known only from Laramidia and Asia. Remarkably, previous studies have postulated the occurrence of latitudinally arrayed dinosaur ‘‘provinces,’’ or ‘‘biomes,’’ on Laramidia. Yet this hypothesis has been challenged on multiple fronts and has remained poorly tested. Methodology/Principal Findings: Here we describe two new, co-occurring ceratopsids from the Upper Cretaceous Kaiparowits Formation of Utah that provide the strongest support to date for the dinosaur provincialism hypothesis. Both pertain to the clade of ceratopsids known as Chasmosaurinae, dramatically increasing representation of this group from the southern portion of the Western Interior Basin of North America.

    The Dinosaur Field Guide Supplement September 2010 – December 2014 By, Zachary Perry (ZoPteryx) Page 1 Disclaimer: This supplement is intended to be a companion for Gregory S. Paul’s impressive work The Princeton Field Guide to Dinosaurs, and as such, exhibits some similarities in format, text, and taxonomy. This was done solely for reasons of aesthetics and consistency between his book and this supplement. The text and art are not necessarily reflections of the ideals and/or theories of Gregory S. Paul. The author of this supplement was limited to using information that was freely available from public sources, and so more information may be known about a given species then is written or illustrated here. Should this information become freely available, it will be included in future supplements. For genera that have been split from preexisting genera, or when new information about a genus has been discovered, only minimal text is included along with the page number of the corresponding entry in The Princeton Field Guide to Dinosaurs. Genera described solely from inadequate remains (teeth, claws, bone fragments, etc.) are not included, unless the remains are highly distinct and cannot clearly be placed into any other known genera; this includes some genera that were not included in Gregory S. Paul’s work, despite being discovered prior to its publication. All artists are given full credit for their work in the form of their last name, or lacking this, their username, below their work. Modifications have been made to some skeletal restorations for aesthetic reasons, but none affecting the skeleton itself.

    __________The Paleontograph________ A newsletter for those interested in all aspects of Paleontology Volume 3 Issue 3 August, 2014 _________________________________________________________________ From Your Editor Hello All, I hope you’ve enjoyed your summer. It has been humid but not too warm here in the Northeast. I’ve just returned from Morocco, where it was very warm. My wife and I spent about a week touring the country and some of its fossil sites. This was a trip I’ve been dreaming about for years and I am very glad I made it. We did not make it to the Trilobite areas but we saw the Phosphate and Orthoceras areas. We met with diggers at their homes and toured factories where the black Orthocersas plates and other items are produced. We also visited some of the normal tourist areas including Marrakech and Casablanca. I’m about to head out to the Denver Show. I will be set up in the Coliseum so if any of you are at the show, please stop by my Lost World Fossils booth on the main floor and say hello. The Paleontograph was created in 2012 to continue what was originally the newsletter of The New Jersey Paleontological Society. The Paleontograph publishes articles, book reviews, personal accounts, and anything else that relates to Paleontology and fossils. Feel free to submit both technical and non-technical work. We try to appeal to a wide range of people interested in fossils. Articles about localities, specific types of fossils, fossil preparation, shows or events, museum displays, field trips, websites are all welcome.
