Fossils give us clues about how humans and different animals lived and evolved. This lesson plan incorporates oral and written language, reading, vocabulary development, science, social studies and critical thinking. The lessons contained in this packet are intended for grades 4 to 6. The activities are designed to be innovative and meet Indiana Academic Standards. The text and worksheets are reproducible. SETTING THE STAGE To begin the lesson plan, you might want the environment of your entire classroom to reflect the ideas of science, geology and discovery. This can be achieved by incorporating this theme into bulletin boards, learning centers, art projects and whatever else you are doing in your classroom. Educators looking for good picture resources for their classroom can contact the Indiana State Museum Store and ask about our The Carr Poster Series, which depicts animals throughout Indiana’s geologic history and includes a geologic timeline. When you set the tone of your classroom in this manner, learning becomes an all- encompassing experience for your students. We encourage you to use this lesson plan as a springboard to further knowledge about fossils and their importance in understanding history. This lesson plan is comprised of four general areas: Geologic Time, Fossil Formation, Discovering Fossils and Paleozoic Fossils. -

New Insights Into the Origin and Relationships of Blastoid Echinoderms
Editors' choice New insights into the origin and relationships of blastoid echinoderms CHRISTOPHER R.C. PAUL Paul, C.R.C. 2021. New insights into the origin and relationships of blastoid echinoderms. Acta Palaeontologica Polo nica 66 (1): 41–62. “Pan-dichoporites” (new informal term) is proposed to unite Cambrian blastozoans, such as Cambrocrinus, Ridersia, and San ducystis, glyptocystitoid and hemicosmitoid rhombiferans, coronates, blastoids, and Lysocystites. Pan-dichoporite ambulacra have double biserial main axes with brachiole facets shared by pairs of floor (glyptocystitoids), side (blastoid) or trunk (hemicosmitoids, coronates) plates. These axial plates are the first two brachiolar plates modified to form the ambulacral axes. In glyptocystitoids the first brachiole facet in each ambulacrum is shared by an oral and another plate. Hence, these are also two modified brachiolar plates and part of the axial skeleton under the Extraxial Axial Theory (EAT). Pan-dichoporites are also characterized by thecae composed of homologous plate circlets. The unique glyptocys- titoid genus Rhombifera bears ambulacral facets on five radial plates, which alternate with five orals. The oral area of Lysocystites (blastoid sensu lato) is very similar, which suggests that rhombiferan radials are homologous with “ambu- lacrals” of Lysocystites and hence with blastoid lancet plates. This implies derivation of blastoids from glyptocystitoids and suggests that blastoid and coronate radials and deltoids are homologous with rhombiferan infralaterals and laterals. Thus, homologous plate circlets occur in all pan-dichoporites, which strengthens the validity of a pan-dichoporite clade. Under Universal Elemental Homology (UEH), deltoids were homologized with rhombiferan orals, but this is inconsistent with the EAT. Deltoids bear respiratory pore structures and so are perforate extraxial skeletal plates, whereas rhombiferan orals are axial skeleton. -

Chapter 5. Paleozoic Invertebrate Paleontology of Grand Canyon National Park
Chapter 5. Paleozoic Invertebrate Paleontology of Grand Canyon National Park By Linda Sue Lassiter1, Justin S. Tweet2, Frederick A. Sundberg3, John R. Foster4, and P. J. Bergman5 1Northern Arizona University Department of Biological Sciences Flagstaff, Arizona 2National Park Service 9149 79th Street S. Cottage Grove, Minnesota 55016 3Museum of Northern Arizona Research Associate Flagstaff, Arizona 4Utah Field House of Natural History State Park Museum Vernal, Utah 5Northern Arizona University Flagstaff, Arizona Introduction As impressive as the Grand Canyon is to any observer from the rim, the river, or even from space, these cliffs and slopes are much more than an array of colors above the serpentine majesty of the Colorado River. The erosive forces of the Colorado River and feeder streams took millions of years to carve more than 290 million years of Paleozoic Era rocks. These exposures of Paleozoic Era sediments constitute 85% of the almost 5,000 km2 (1,903 mi2) of the Grand Canyon National Park (GRCA) and reveal important chronologic information on marine paleoecologies of the past. This expanse of both spatial and temporal coverage is unrivaled anywhere else on our planet. While many visitors stand on the rim and peer down into the abyss of the carved canyon depths, few realize that they are also staring at the history of life from almost 520 million years ago (Ma) where the Paleozoic rocks cover the great unconformity (Karlstrom et al. 2018) to 270 Ma at the top (Sorauf and Billingsley 1991). The Paleozoic rocks visible from the South Rim Visitors Center, are mostly from marine and some fluvial sediment deposits (Figure 5-1). -

Multi−Snail Infestation of Devonian Crinoids and the Nature of Platyceratid−Crinoid Interactions
Multi−snail infestation of Devonian crinoids and the nature of platyceratid−crinoid interactions TOMASZ K. BAUMILLER Baumiller, T.K. 2002. Multi−snail infestation of Devonian crinoids and the nature of platyceratid−crinoid interactions. Acta Palaeontologica Polonica 47 (1): 133–139. The well−known association of platyceratid snails and crinoids typically involves a single snail positioned on the tegmen of the crinoid host; this has led to the inference of coprophagy. Two specimens of the camerate crinoid Arthroacantha from the Middle Devonian Silica Formation of Ohio, USA, exhibit numerous snails on their tegmens. On one of these, 6 platyceratid juveniles of approximately equal size are found on the tegmen. On the second crinoid, the largest of 7 in− festing platyceratids occupies the typical position over the anal vent while others are either superposed (tiered) upon it or are positioned elsewhere on the tegmen. These specimens illustrate that platyceratids (1) settled on crinoids as spat, (2) were not strictly coprophagous during life yet (3) benefited from a position over the anal vent.
