In these times of economic storm and stress, however, it seems more appropriate that I should take stock of the progress of our science, briefly review the past, and consider the present, so that we may plan and build more firmly for the future, and it is par­ ticularly desirable that someone should call attention not only to our opportunities but to certain of our failings. I have restricted my re­ marks to invertebrate paleontology because of my greater familiarity with that division of the subject. My topics are matters well known to us all; indeed, perhaps so familiar that we do not always accord them proper attention in our work, and so I venture to recall them to you in the interest of better results in our science. American invertebrate paleontology set the standard for the world during the latter half of the nineteenth century. With all our resources and superior opportunities for publication, is this the case today? And, if not, why not ?

Thus, Cotton Mather, in 1714, in describing fossil elephant bones and teeth, identified them as relics of the antediluvian giants of the Scriptures. The work of our paleontologist-statesman, Thomas Jefferson, on the Great Claw or Megalonyx, read in 1797, is classic; and his continued studies of vertebrate paleontology after his election to the presidency, with the conversion of a part of the White House into a paleontological mu­ seum, are known to us all. These striking extinct vertebrate remains had greatest significance for students of zoology and evolution, and their study was usually pursued along these lines. It was not astonishing, therefore, that the paleontology of invertebrate animals and plants, fos­ sils less conspicuous but more interwoven with the science of stratigraphy, did not commence until a later date. Until 1820, American geology was generally dominated by the Werne­ rian ideas of William Maclure, although in 1818 Amos Eaton had published his “Index to the Geology of the Northern States” which, although still tinged with Wernerism, contained the first definite attempt to arrange the geological strata of North America in logical order. Here in the red sand­ stones of the Catskills, Eaton noted a fossil plant, identifying it as a petrified root of the common laurel. Long before this, however, in 1752, Jean Etienne Guettard had examined a collection of fossils from Canada and endeavored to establish a subdivision of the rocks, based on them, thus being one of the first men to recognize geology as an historical science. The decade in American geology which began in 1820 was, as George P. Merrill points out in his valuable volume, “The First One Hundred Years of American Geology,” noted for the first systematic effort in America to correlate strata by fossils. This decade was dominated by and named after Amos Eaton, the most prominent worker of the time. In the second edition of his index, Eaton took up the subject of fossils, classifying them as petrifactions and conservations. The latter were fossils still composed of the same material as the living organisms, while the petrifactions were relics made up of mineral matter which had run into the place occupied by the body before it decayed. The nomenclature of fossils was a simple matter at that time, and Eaton classified all organic remains under nine genera. For example, all fishes belonged, according to him, to the genus Ichthyolites, and all shells to Concholites. It was Thomas Nuttall, in the account of his travels in the Great Lakes region published in 1820, who Downloaded from http://pubs.geoscienceworld.org/gsa/gsabulletin/article-pdf/44/2/265/3414963/BUL44_2-0265.pdf by guest on 30 September 2021 HISTORICAL BACKGROUND 267 made the first serious attempt to correlate the rocks of North America by means of invertebrate fossils. Nuttall antedates by fifteen years similar efforts by Morton on the Tertiary of the Atlantic Coastal Plain, and by a longer time the researches of James Hall and other New York geologists. Shortly after Nutt all’s work, there appeared some of the earliest descrip­ tions of species of American invertebrate fossils. Among these were those published by John J. Bigsby, a surgeon of the British Army, who was stationed in Canada. So much of the work of the next fifty years of American geology and paleontology, beginning in 1830, was done by the state geological surveys that Dr. Merrill has appropriately named it “The Era of State Surveys.” Early in this era Maclure and Eaton were still active, but there soon rose to prominence such paleontologists as Timothy A. Conrad and James Hall. Systematic paleontological research upon the Tertiary shells of North America commenced with Conrad’s first work upon the subject in 1832. With the inauguration of the Geological Survey of New York in 1836, and the appointment of James Hall as a member, Paleozoic in­ vertebrate paleontology came into its own, and the great series of New York paleontologic volumes was inaugurated. In succession other states initiated surveys, many of them devoting at least a part of their publica­ tions to paleontology. Ohio, Illinois, and Minnesota are conspicuous ex­ amples of states which added especially noteworthy contributions to in­ vertebrate paleontology. Then, in the middle of the century, Elkanah Billings was appointed on the Geological Survey of Canada under Sir William Logan, and for two decades he did excellent work upon the Paleozoic invertebrate fossils of that country. The latter half of the Era of State Surveys was conspicuous for various exploring expeditions to the West, which resulted especially in important additions to our knowledge of post-Paleozoic fossils. The Civil War brought forth men of great physical and moral courage for these expedi­ tions. The West was now beckoning, and Congress was willing to appro­ priate funds for its exploration. At first military in their nature, these expeditions soon added geographic explorations to the scope of their work. Then military, geographic, and geologic aims were combined, and finally geological and natural history researches became the prime objects of these endeavors. Hayden’s “Geological Survey of the Territories,” King’s “Geological Survey of the 40th Parallel,” Powell’s “Survey of the Rocky Mountain Region,” and Wheeler’s “Survey west of the 100th Meridian” are well known. Meek was the outstanding paleontologist of these surveys, although not officially connected with any of them. He early became Downloaded from http://pubs.geoscienceworld.org/gsa/gsabulletin/article-pdf/44/2/265/3414963/BUL44_2-0265.pdf by guest on 30 September 2021 268 E. S. BASSLEE----INVEETEBEATE PALEONTOLOGY 11ST AMEEICA associated with Hayden, and continued to study the fossils collected by the territorial surveys until after Hayden’s death. Arriving in Washington in 1858, Meek had a room in the Smithsonian building where he lived and did all his work during the rest of his life. Had he possessed the energy of a Hall and been of a less retiring disposition, he undoubtedly would have become the outstanding paleontologist of this period. The territorial explorations culminated in 1879 in the founding of the United States Geological Survey, the greatest institution in the world’s history for the increase of geological knowledge. Under the Survey, invertebrate paleontology has been encouraged equally with vertebrate paleontology and paleobotany, and the many important memoirs by the paleontologist-director, Charles D. Walcott, and other

    Buzzle – Zoology Terms – Glossary of Biology Terms and Definitions http://www.buzzle.com/articles/biology-terms-glossary-of-biology-terms-and- definitions.html#ZoologyGlossary Biology is the branch of science concerned with the study of life: structure, growth, functioning and evolution of living things. This discipline of science comprises three sub-disciplines that are botany (study of plants), Zoology (study of animals) and Microbiology (study of microorganisms). This vast subject of science involves the usage of myriads of biology terms, which are essential to be comprehended correctly. People involved in the science field encounter innumerable jargons during their study, research or work. Moreover, since science is a part of everybody's life, it is something that is important to all individuals. A Abdomen: Abdomen in mammals is the portion of the body which is located below the rib cage, and in arthropods below the thorax. It is the cavity that contains stomach, intestines, etc. Abscission: Abscission is a process of shedding or separating part of an organism from the rest of it. Common examples are that of, plant parts like leaves, fruits, flowers and bark being separated from the plant. Accidental: Accidental refers to the occurrences or existence of all those species that would not be found in a particular region under normal circumstances. Acclimation: Acclimation refers to the morphological and/or physiological changes experienced by various organisms to adapt or accustom themselves to a new climate or environment. Active Transport: The movement of cellular substances like ions or molecules by traveling across the membrane, towards a higher level of concentration while consuming energy.

    Society of Vertebrate Paleontology 7918 Jones Branch Drive, Suite 300 McLean, VA 22102 USA Phone: (301) 634-7024 Email: [email protected] Web: www.vertpaleo.org FEIN: 06-0906643 April 21, 2020 Subject: Fossils from conflict zones and reproducibility of fossil-based scientific data Dear Editors, We are writing you today to promote the awareness of a couple of troubling matters in our scientific discipline, paleontology, because we value your professional academic publication as an important ‘gatekeeper’ to set high ethical standards in our scientific field. We represent the Society of Vertebrate Paleontology (SVP: http://vertpaleo.org/), a non-profit international scientific organization with over 2,000 researchers, educators, students, and enthusiasts, to advance the science of vertebrate palaeontology and to support and encourage the discovery, preservation, and protection of vertebrate fossils, fossil sites, and their geological and paleontological contexts. The first troubling matter concerns situations surrounding fossils in and from conflict zones. One particularly alarming example is with the so-called ‘Burmese amber’ that contains exquisitely well-preserved fossils trapped in 100-million-year-old (Cretaceous) tree sap from Myanmar. They include insects and plants, as well as various vertebrates such as lizards, snakes, birds, and dinosaurs, which have provided a wealth of biological information about the ‘dinosaur-era’ terrestrial ecosystem. Yet, the scientific value of these specimens comes at a cost (https://www.nytimes.com/2020/03/11/science/amber-myanmar-paleontologists.html). Where Burmese amber is mined in hazardous conditions, smuggled out of the country, and sold as gemstones, the most disheartening issue is that the recent surge of exciting scientific discoveries, particularly involving vertebrate fossils, has in part fueled the commercial trading of amber.

  • Vertebrates and Invertebrates
    Vertebrates and invertebrates The animal kingdom is divided into two groups: vertebrates and invertebrates. Vertebrates have been around for millions of years but have evolved and changed over time. The word vertebrate means “having a backbone." Many animals have backbones. You have a backbone. So does a cow, a whale, a fish, a frog, and a bird. Vertebrates are animals that have a backbone. Most animals have a backbone that is made of bones joined together to form a skeleton. Our skeleton gives us our shape and allows us to move. Mammals, fish, birds, reptiles, and amphibians have Vertebrae backbones so they are all vertebrates. Each bone that makes up the backbone Scientists classify vertebrates into five classes: is called a vertebra. These are the • Mammals building blacks that form the backbone, • Fish also known as the spinal cord. The • Birds vertebrae protect and support your • Reptiles spine. Without a backbone, you would not • Amphibians be able to move any part of your body. Animals without a backbone are called invertebrates. Most The human animals are invertebrates.

  • Fun Facts: Incredible Invertebrates 40 Minutes Age 7-11
    Fun Facts: Incredible Invertebrates 40 minutes Age 7-11 1. Invertebrates are animals that do not have a backbone. Some common invertebrates are worms, snails, corals, sponges, insects, jellyfish, and crustaceans (Brsuca and Brusca, 2003). 2. Invertebrates first evolved during the Cambrian Period, over 540 million years ago (Brusca and Brusca, 2003) 3. Over 95% of the 1.4 million known animal species are invertebrates (Smithsonian, 2018) 4. The largest invertebrate is the colossal squid which can weigh over 500kg and reach lengths of up to 14m (Ravaiolo and Youngster, 2012). 5. Corals are sessile invertebrates, meaning they are fixed in one place and unable to relocate. Corals grow at different rates, with some growing up to 10cm in one year and others only growing 0.3cm in one year (Barnes, 1987). 6. Many species of marine worms, such as feather duster and Christmas tree worms, survive by hiding their body in a tube attached to the reef. They feed by extending their gills into the water and catching phytoplankton and other microscopic organisms in the water column (NOAA, 2020). 7. Sea stars and sea urchins are some important species of invertebrates that have specialized organs called tube feet, which allow them to move and feed. The tube feet have two special types of cells. The first type of cell releases a glue-like substance that allows the tube feet to stick and hold onto different structures. The second type of cell releases a substance that breaks down the glue-like substance and allows the tube feet to release from the structure (Flammang et al., 2005).

  • Cnidarian Immunity and the Repertoire of Defense Mechanisms in Anthozoans
    biology Review Cnidarian Immunity and the Repertoire of Defense Mechanisms in Anthozoans Maria Giovanna Parisi 1,* , Daniela Parrinello 1, Loredana Stabili 2 and Matteo Cammarata 1,* 1 Department of Earth and Marine Sciences, University of Palermo, 90128 Palermo, Italy; [email protected] 2 Department of Biological and Environmental Sciences and Technologies, University of Salento, 73100 Lecce, Italy; [email protected] * Correspondence: [email protected] (M.G.P.); [email protected] (M.C.) Received: 10 August 2020; Accepted: 4 September 2020; Published: 11 September 2020 Abstract: Anthozoa is the most specious class of the phylum Cnidaria that is phylogenetically basal within the Metazoa. It is an interesting group for studying the evolution of mutualisms and immunity, for despite their morphological simplicity, Anthozoans are unexpectedly immunologically complex, with large genomes and gene families similar to those of the Bilateria. Evidence indicates that the Anthozoan innate immune system is not only involved in the disruption of harmful microorganisms, but is also crucial in structuring tissue-associated microbial communities that are essential components of the cnidarian holobiont and useful to the animal’s health for several functions including metabolism, immune defense, development, and behavior. Here, we report on the current state of the art of Anthozoan immunity. Like other invertebrates, Anthozoans possess immune mechanisms based on self/non-self-recognition. Although lacking adaptive immunity, they use a diverse repertoire of immune receptor signaling pathways (PRRs) to recognize a broad array of conserved microorganism-associated molecular patterns (MAMP). The intracellular signaling cascades lead to gene transcription up to endpoints of release of molecules that kill the pathogens, defend the self by maintaining homeostasis, and modulate the wound repair process.

  • Nanostructure of Biogenic Versus Abiogenic Calcium Carbonate Crystals
    Nanostructure of biogenic versus abiogenic calcium carbonate crystals JAROSŁAW STOLARSKI and MACIEJ MAZUR Stolarski, J. and Mazur, M. 2005. Nanostructure of biogenic versus abiogenic calcium carbonate crystals. Acta Palae− ontologica Polonica 50 (4): 847–865. The mineral phase of the aragonite skeletal fibers of extant scleractinians (Favia, Goniastrea) examined with Atomic Force Microscope (AFM) consists entirely of grains ca. 50–100 nm in diameter separated from each other by spaces of a few nanometers. A similar pattern of nanograin arrangement was observed in basal calcite skeleton of extant calcareous sponges (Petrobiona) and aragonitic extant stylasterid coralla (Adelopora). Aragonite fibers of the fossil scleractinians: Neogene Paracyathus (Korytnica, Poland), Cretaceous Rennensismilia (Gosau, Austria), Trochocyathus (Black Hills, South Dakota, USA), Jurassic Isastraea (Ostromice, Poland), and unidentified Triassic tropiastraeid (Alpe di Specie, It− aly) are also nanogranular, though boundaries between individual grains occasionally are not well resolved. On the other hand, in diagenetically altered coralla (fibrous skeleton beside aragonite bears distinct calcite signals) of the Triassic cor− als from Alakir Cay, Turkey (Pachysolenia), a typical nanogranular pattern is not recognizable. Also aragonite crystals produced synthetically in sterile environment did not exhibit a nanogranular pattern. Unexpectedly, nanograins were rec− ognized in some crystals of sparry calcite regarded as abiotically precipitated. Our findings support the idea that nanogranular organization of calcium carbonate fibers is not, per se, evidence of their biogenic versus abiogenic origin or their aragonitic versus calcitic composition but rather, a feature of CaCO3 formed in an aqueous solution in the presence of organic molecules that control nanograin formation. Consistent orientation of crystalographic axes of polycrystalline skeletal fibers in extant or fossil coralla, suggests that nanograins are monocrystalline and crystallographically ordered (at least after deposition).
