YALE Environmental NEWS yale environmental n e w s The Peabody Museum of Natural History, the School of Forestry & Environmental Studies, and the Yale Institute for Biospheric Studies spring 2006 vol. 11, no. 2 The Peabody’s Torosaurus is a new and prominent presence on the Connecticut landscape and the first full-size public work of a dinosaur in New England. The Yale Peabody Museum brought together paleontologists, zoolo- gists, and an army of artists and volunteers to create a 2-foot, life- size bronze sculpture of Torosaurus. The 7,350-pound sculpture sits on a 3-foot, 70-ton base of Stony Creek granite, the same granite used for the base of the Statue of Liberty. yale environmental news The Science Behind the Peabody’s Torosaurus Statue By Daniel Brinkman, Museum Assistant, Division of Vertebrate Paleontology, and Jane Pickering, Assistant Director for Public Programs The Yale Peabody Museum’s new Torosaurus Torosaurus latus have ever been discovered, statue on Whitney Avenue is rapidly becom- nearly every other part of the Peabody’s sculp- ing one of the most popular exhibits at the ture is based on the anatomy or appearance of Museum, and visitors often ask whether it is some of Torosaurus’s better-known living and “accurate.” Torosaurus fossils are extremely extinct relatives.

  • 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.

  • Recognizing Women Leaders in Fire Science: Revisited
    fire Editorial Recognizing Women Leaders in Fire Science: Revisited Alistair M.S. Smith * and Eva K. Strand College of Natural Resources, University of Idaho, Moscow, ID 83844, USA; [email protected] * Correspondence: [email protected] Received: 13 November 2018; Accepted: 14 November 2018; Published: 21 November 2018 Abstract: In August, 2018, an editorial in Fire entitled Recognizing Women Leaders in Fire Science was published. This was intended to ignite a conversation into diversity in fire science by highlighting several women leaders in fire research and development. This editorial was released alongside a new Topical Collection in Fire called Diversity Leaders in Fire Science. The response on social media was fantastic, leading to numerous recommendations of women leaders in fire science that had been inadvertently missed in the first editorial. In this editorial, we acknowledge 145 women leaders in fire science to promote diversity across our disciplines. Fire is continually committed to improving diversity and inclusion in all aspects of the journal and welcomes perspectives, viewpoints, and constructive criticisms to help advance that mission. Keywords: leadership; women in science 1. Introduction Following the release of the initial editorial, Recognizing Women Leaders in Fire Science [1], we received over 100 recommendations from Twitter and other forms of social media of potential other women leaders in fire science. As such, this follow-up editorial seeks to acknowledge these women leaders in fire science to promote diversity across our disciplines. 2. Approach The approach differed from the first editorial, whereby the absence of a women in fire science database or search heuristic (e.g., being able to search “women” AND “fire science”) resulted in recommendations being predominately derived through the co-authors’ own knowledge of the discipline and conversations across an extended network of international collaborators.

  • Raptors in Action 1 Suggested Pre-Visit Activities
    PROGRAM OVERVIEW TOPIC: Small theropods commonly known as “raptors.” THEME: Explore the adaptations that made raptors unique and successful, like claws, intelligence, vision, speed, and hollow bones. PROGRAM DESCRIPTION: Razor-sharp teeth and sickle-like claws are just a few of the characteristics that have made raptors famous. Working in groups, students will build a working model of a raptor leg and then bring it to life while competing in a relay race that simulates the hunting techniques of these carnivorous animals. AUDIENCE: Grades 3–6 CURRICULUM CONNECTIONS: Grade 3 Science: Building with a Variety of Materials Grade 3–6 Math: Patterns and Relations Grade 4 Science: Building Devices and Vehicles that Move Grade 6 Science: Evidence and Investigation PROGRAM ObJECTIVES: 1. Students will understand the adaptations that contributed to the success of small theropods. 2. Students will explore the function of the muscles used in vertebrate movement and the mechanics of how a raptor leg works. 3. Students will understand the function of the raptorial claw. 4. Students will discover connections between small theropod dinosaurs and birds. SUGGESTED PRE-VISIT ACTIVITIES UNDERstANDING CLADIstICS Animals and plants are often referred to as part of a family or group. For example, the dog is part of the canine family (along with wolves, coyotes, foxes, etc.). Scientists group living things together based on relationships to gain insight into where they came from. This helps us identify common ancestors of different organisms. This method of grouping is called “cladistics.” Cladistics is a system that uses branches like a family tree to show how organisms are related to one another.

This is one of many related papers that were included in the 2005 NMGS Fall Field Conference Guidebook. Annual NMGS Fall Field Conference Guidebooks Every fall since 1950, the New Mexico Geological Society (NMGS) has held an annual Fall Field Conference that explores some region of New Mexico (or surrounding states). Always well attended, these conferences provide a guidebook to participants. Besides detailed road logs, the guidebooks contain many well written, edited, and peer-reviewed geoscience papers. These books have set the national standard for geologic guidebooks and are an essential geologic reference for anyone working in or around New Mexico. Free Downloads NMGS has decided to make peer-reviewed papers from our Fall Field Conference guidebooks available for free download. Non-members will have access to guidebook papers two years after publication. Members have access to all papers. This is in keeping with our mission of promoting interest, research, and cooperation regarding geology in New Mexico. However, guidebook sales represent a significant proportion of our operating budget. Therefore, only research papers are available for download. Road logs, mini-papers, maps, stratigraphic charts, and other selected content are available only in the printed guidebooks.
