  • A New Species of Tiaracrinus from the Latest Emsian of Morocco and Its Phylogeny
    A new species of Tiaracrinus from the latest Emsian of Morocco and its phylogeny CHRISTIAN KLUG, KENNETH DE BAETS, CAROLE JUNE NAGLIK, and JOHNNY WATERS Klug, C., De Baets, K., Naglik, C.J., and Waters, J. 2014. A new species of Tiaracrinus from the latest Emsian of Morocco and its phylogeny. Acta Palaeontologica Polonica 59 (1): 135–145. We describe a new species of the unusual crinoid Tiaracrinus, T. jeanlemenni sp. nov. from the latest Emsian of the fa- mous mudmound locality Hamar Laghdad, Morocco. It differs from the previously known species in the higher number of ribs and the vaulted rib-fields, which is corroborated by the comparison of simple quantitative characters and ratios as well as by the results of a cluster analysis and a Principal Component Analysis. Based on the new material and the published specimens, we discuss the phylogeny of the genus and suggest that T. oehlerti and T. moravicus represent the ancestral forms of this small clade. Key words: Crinoidea, mudmounds, phylogeny, morphometry, symmetry, Devonian, Morocco. Christian Klug [[email protected]] and Carole J.

  • Analysis of Polarimetric Mini-SAR and Mini-RF Datasets for Surface Characterization and Crater Delineation on Moon †
    Proceeding Paper Analysis of Polarimetric Mini-SAR and Mini-RF Datasets for Surface Characterization and Crater Delineation on Moon † Himanshu Kumari and Ashutosh Bhardwaj * Photogrammetry and Remote Sensing Department, Indian Institute of Remote Sensing, Dehradun 248001, India; [email protected] * Correspondence: [email protected]; Tel.: +91-9410319433 † Presented at the 3rd International Electronic Conference on Atmospheric Sciences, 16–30 November 2020; Available online: https://ecas2020.sciforum.net/. Abstract: The hybrid polarimetric architecture of Mini-SAR and Mini-RF onboard Indian Chan- drayaan-1 and LRO missions were the first to acquire shadowed polar images of the Lunar surface. This study aimed to characterize the surface properties of Lunar polar and non-polar regions con- taining Haworth, Nobile, Gioja, an unnamed crater, Arago, and Moltke craters and delineate the crater boundaries using a newly emerged approach. The Terrain Mapping Camera (TMC) data of Chandrayaan-1 was found useful for the detection and extraction of precise boundaries of the cra- ters using the ArcGIS Crater tool. The Stokes child parameters estimated from radar backscatter like the degree of polarization (m), the relative phase (δ), Poincare ellipticity (χ) along with the Circular Polarization Ratio (CPR), and decomposition techniques, were used to study the surface attributes of craters. The Eigenvectors and Eigenvalues used to measure entropy and mean alpha showed distinct types of scattering, thus its comparison with m-δ, m-χ gave a profound conclusion to the lunar surface. The dominance of surface scattering confirmed the roughness of rugged material. The results showed the CPR associated with the presence of water ice as well as a dihedral reflection inside the polar craters.

RETALLACK Department of Earth Sciences, University of Oregon, Eugene, OR 97403, USA. *Email: gregr@uoregon. edu (Received 09 September, 2019; revised version accepted 15 December, 2019) ABSTRACT The Palaeobotanist 68(1–2): Retallack GJ 2019. Ordovician land plants and fungi from Douglas Dam, Tennessee. The Palaeobotanist 68(1–2): xxx–xxx. 1–33. Ordovician land plants have long been suspected from indirect evidence of fossil spores, plant fragments, carbon isotopic studies, and paleosols, but now can be visualized from plant compressions in a Middle Ordovician (Darriwilian or 460 Ma) sinkhole at Douglas Dam, Tennessee, U. S. A. Five bryophyte clades and two fungal clades are represented: hornwort (Casterlorum crispum, new form genus and species), liverwort (Cestites mirabilis Caster & Brooks), balloonwort (Janegraya sibylla, new form genus and species), peat moss (Dollyphyton boucotii, new form genus and species), harsh moss (Edwardsiphyton ovatum, new form genus and species), endomycorrhiza (Palaeoglomus strotheri, new species) and lichen (Prototaxites honeggeri, new species). The Douglas Dam Lagerstätte is a benchmark assemblage of early plants and fungi on land. Ordovician plant diversity now supports the idea that life on land had increased terrestrial weathering to induce the Great Ordovician Biodiversification Event in the sea and latest Ordovician (Hirnantian)
