Robbin Moran New York Botanical Garden George Yatskievych and Ann Larson Missouri Botanical Garden Jan De Laet, plantsystematics.org Th is pdf is a companion publication to Rhode Island Equisetopsida, Lycopodiopsida & Isoetopsida at among-ri-wildfl owers.org Th e Elfi n Press 2016 Introduction Formerly known as fern allies, Horsetails, Club-mosses, Fir-mosses, Spike-mosses and Quillworts are plants that have an alternate generation life-cycle similar to ferns, having both sporophyte and gametophyte stages. Equisetopsida Horsetails date from the Devonian period (416 to 359 million years ago) in earth’s history where they were trees up to 110 feet in height and helped to form the coal deposits of the Carboniferous period. Only one genus has survived to modern times (Equisetum). Horsetails Horsetails (Equisetum) have jointed stems with whorls of thin narrow leaves. In the sporophyte stage, they have a sterile and fertile form. Th ey produce only one type of spore. While the gametophytes produced from the spores appear to be plentiful, the successful reproduction of the sporophyte form is low with most Horsetails reproducing vegetatively. Lycopodiopsida Lycopodiopsida includes the clubmosses (Dendrolycopodium, Diphasiastrum, Lycopodiella, Lycopodium , Spinulum) and Fir-mosses (Huperzia) Clubmosses Clubmosses are evergreen plants that produce only microspores that develop into a gametophyte capable of producing both sperm and egg cells. Club-mosses can produce the spores either in leaf axils or at the top of their stems. Th e spore capsules form in a cone-like structures (strobili) at the top of the plants. -

The SR-86 /Avenue 50 New Interchange Project (Project) consists of converting a portion of SR-86 from an existing expressway to a freeway with a new overcrossing structure and access ramps. In addition, the proposed Project includes the realignment and widening of Avenue 50 and the realignment of portions of Tyler Street on both the east and west sides of SR-86. Finally, the Project would construct a new bridge over the Coachella Valley Stormwater Channel (CVSC) to replace the existing low water crossing. At the request of TranSystems, Applied EarthWorks, Inc. (Æ) performed a paleontological resource assessment in support of the proposed Project. The study consisted of a search of museum collections records maintained by the Natural History Museum of Los Angeles County, a comprehensive literature and geologic map review, a field reconnaissance survey, and preparation of this combined Paleontological Identification Report (PIR) / Paleontological Evaluation Report (PER). -

Unit-V Evolution of Horse
UNIT-V EVOLUTION OF HORSE Horses (Equus) are odd-toed hooped mammals belong- ing to the order Perissodactyla. Horse evolution is a straight line evolution and is a suitable example for orthogenesis. It started from Eocene period. The entire evolutionary sequence of horse history is recorded in North America. " Place of Origin The place of origin of horse is North America. From here, horses migrated to Europe and Asia. By the end of Pleis- tocene period, horses became extinct in the motherland (N. America). The horses now living in N. America are the de- scendants of migrants from other continents. Time of Origin The horse evolution started some 58 million years ago, m the beginning of Eocene period of Coenozoic era. The modem horse Equus originated in Pleistocene period about 2 million years ago. Evolutionary Trends The fossils of horses that lived in different periods, show that the body parts exhibited progressive changes towards a particular direction. These directional changes are called evo- lutionary trends. The evolutionary trends of horse evolution are summarized below: 1. Increase in size. 2. Increase in the length of limbs. 3. Increase in the length of the neck. 4. Increase in the length of preorbital region (face). 5. Increase in the length and size of III digit. 6. Increase in the size and complexity of brain. 7. Molarization of premolars. Olfactory bulb Hyracotherium Mesohippus Equus Fig.: Evolution of brain in horse. 8. Development of high crowns in premolars and molars. 9. Change of plantigrade gait to unguligrade gait. 10. Formation of diastema. 11. Disappearance of lateral digits. -
Distinguishing Quaternary Glyptodontine Cingulates in South America: How Informative Are Juvenile Specimens?
Distinguishing Quaternary glyptodontine cingulates in South America: How informative are juvenile specimens? CARLOS A. LUNA, IGNACIO A. CERDA, ALFREDO E. ZURITA, ROMINA GONZALEZ, M. CECILIA PRIETO, DIMILA MOTHÉ, and LEONARDO S. AVILLA Luna, C.A., Cerda, I.A., Zurita, A.E., Gonzalez, R., Prieto, M.C., Mothé, D., and Avilla, L.S. 2018. Distinguishing Quaternary glyptodontine cingulates in South America: How informative are juvenile specimens? Acta Palaeontologica Polonica 63 (1): 159–170. The subfamily Glyptodontinae (Xenarthra, Cingulata) comprises one of the most frequently recorded glyptodontids in South America. Recently, the North American genus Glyptotherium was recorded in South America, in addition to the genus Glyptodon. It has been shown that both genera shared the same geographic distribution in central-north and eastern areas of South America (Venezuela and Brazil, respectively). Although some characters allow differentiation between adult specimens of both genera, the morphological distinction between these two genera is rather difficult in juvenile specimens. In this contribution, a detailed morphological, morphometric and histological survey of a juvenile specimen of Glyptodontinae recovered from the Late Pleistocene of northern Brazil is performed. The relative lower osteoderms thickness, the particular morphology of the annular and radial sulci and the distal osseous projections of the caudal osteoderms suggest that the specimen belongs to the genus Glyptotherium. In addition, the validity of some statistical tools to distinguish between different ontogenetic stages and in some cases between genera is verified. The osteoderm microstructure of this juvenile individual is characterized by being composed of a cancellous internal core surrounded by a compact bone cortex. Primary bone tissue mostly consists of highly vascularized, woven-fibered bone tissue. -

Read each section and complete the tasks. DO NOT EDIT--Changes must be made through “File info” CorrectionKey=CA-B FIGURE 1: This creosote ring in the Mojave Desert is estimated to be 11 700 years old . This makes it one of the oldest living organisms on Earth . The creosote bush is thought to be the most drought-tolerant plant in North America. It has a variety of adaptations to its desert environment, including its reproductive tendency to clone outward in rings rather than rely solely on seed production. The plant’s leaves are coated in a foul-tasting resin that protects it from water loss through evaporation and from grazing. It only opens its stomata in the morning to pull in carbon dioxide for photosynthesis from the more humid air and closes them as the day’s temperature increases. It also has a root system that consists of both an exceptionally long tap root and a vast network of shallow feeder roots. Creosote bushes exhibit two different shapes to fit different microclimates. In drier areas, the plant has a cone shape in which stems funnel rainwater into the taproot. In wetter areas, the bush has a more rounded shape that provides shade to its shallow feeder roots. PREDICT How do species change over time to adjust to varying conditions? DRIVING QUESTIONS As you move through the unit, gather evidence to help you answer the following questions. -

In this study, we developed a nontoxic method to concentrate calcareous microfossils from gypsum (CaSO 2H O), by treating the sulfate with 4· 2 ammonium acetate. We applied the newly developed method to gypsum collected from the Evaporitic Formation outcropping northward of Slănic-Prahova in the Eastern Carpathians. For the first time for this formation, we describe a calcareous microfossil assemblage characterized by the presence of planktonic foraminifera as well as cysts and fragments of calcareous algae. Keywords: chemical preparation method; gypsum deposits; calcareous microfossil assemblage; Miocene; Eastern Carpathians 1. Introduction In the Earth’s history, sulfate rich marine waters are known for late Precambrian (Vendian), Pennsylvanian-Triassic, Miocene to Quaternary [1]. -
Distributions of Extinction Times from Fossil Ages and Tree Topologies: the Example of Some Mid-Permian Synapsid Extinctions

Distributions of extinction times from fossil ages and tree topologies: the example of some mid-Permian synapsid extinctions Gilles Didier1 and Michel Laurin2 1IMAG, Univ Montpellier, CNRS, Montpellier, France 2CR2P (“Centre de Recherches sur la Paléobiodiversité et les Paléoenvironnements”; UMR 7207), CNRS/MNHN/UPMC, Sorbonne Université, Muséum National d’Histoire Naturelle, Paris, France June 11, 2021 Abstract Given a phylogenetic tree of extinct and extant taxa with fossils where the only temporal infor- mation stands in the fossil ages, we devise a method to compute the distribution of the extinction time of a given set of taxa under the Fossilized-Birth-Death model. Our approach differs from the previous ones in that it takes into account the possibility that the taxa or the clade considered may diversify before going extinct, whilst previous methods just rely on the fossil recovery rate to estimate confidence intervals. We assess and compare our new approach with a standard previous one using simulated data. Results show that our method provides more accurate confidence intervals. This new approach is applied to the study of the extinction time of three Permo-Carboniferous synapsid taxa (Ophiacodontidae, Edaphosauridae, and Sphenacodontidae) that are thought to have disappeared toward the end of the Cisuralian, or possibly shortly thereafter. The timing of extinctions of these three taxa and of their component lineages supports the idea that a biological crisis occurred in the late Kungurian/early Roadian. -
