Antodendrina Wisshak 2017, igen. nov.
No full textAntodendrina igen. nov. urn:lsid:zoobank.org:act: F13A16FD-226A-4AFB-852A-3A53A2C3E2FF Type ichnospecies Antodendrina ligula igen. et isp. nov. Diagnosis Closely prostrate bioerosion trace in calcareous skeletal substrates, with radiating and distally widening lobes emerging from a central cavity, the latter and the lobes being in direct lateral contact to the substrate surface or forming open depressions. Etymology Latinised from the ancient Greek ‘ἄνΘος’ (antos), blossom, and ‘δένδρον’ (dendron), tree, referring to the blossom-like radial appearance of this dendrinid’s outline. Remarks The diagnostic morphological feature of a central depression with radiating club- to spoon-shaped lobes is unique among the Dendrinidae and is the primary ichnotaxobase of this new ichnogenus. Unlike Dendrina, the radiating lobes are in direct contact with the substrate surface.Published as part of Wisshak, Max, 2017, Taming an ichnotaxonomical Pandora's box: revision of dendritic and rosetted microborings (ichnofamily: Dendrinidae), pp. 1-99 in European Journal of Taxonomy 390 on pages 77-78, DOI: 10.5852/ejt.2017.390, http://zenodo.org/record/383985

Abeliella procera Magdefrau 1937
No full textAbeliella procera Mägdefrau, 1937 Fig. 18 Abeliella procera Mägdefrau, 1937: 61, pl. V, fig. 2. Original diagnosis n/a Emended diagnosis Dichotomous ramification in acute angles and with long internodes. Tunnels of constant diameter and slightly meandering course. Original description Entire cavity system ca 0.5 mm in diameter. Tunnels weaker, with slightly meandering course, distance between bifurcations larger, branching angle smaller, and thus overall appearance more slender compared to A. riccioides. [Translated from German] Type material, locality and horizon Traces in fish scale from the Oligocene Septarienton of Eöthen, Germany, deposited in the collections of the Institut für Geowissenschaften und Geographie, Halle, Germany (MLU. Mäg1937. V.2). Because the scale contains several specimens of A. procera (syntypes), the most complete one (Fig. 18B) is hereby designated as the lectotype, which is in accordance with the original figure (Mägdefrau 1937: pl. V, fig. 2). Remarks This ichnospecies is distinguished from A. riccioides by its significantly longer internodes, a slightly meandering course of the tunnels, and more acute branching angles.Published as part of Wisshak, Max, 2017, Taming an ichnotaxonomical Pandora's box: revision of dendritic and rosetted microborings (ichnofamily: Dendrinidae), pp. 1-99 in European Journal of Taxonomy 390 on pages 51-52, DOI: 10.5852/ejt.2017.390, http://zenodo.org/record/383985

Diagnosis Bioerosion trace in calcareous skeletal substrates with a tubular, straight to arcuate entrance tunnel leading to a prostrate plexus of ramifying or anastomosing galleries, forming up to a semicircle to one side of the point of entry. Etymology Latinised from the ancient Greek ‘ρóπαλον’ (rhopalon), club, and ‘δένδρον’ (dendron), tree, referring to the club-shaped widening of terminal galleries in the type ichnospecies, and acknowledging the corresponding informal naming of the Rhopalondendrina-Form by Ingrid Glaub (1994). Remarks Distinguished from Nododendrina by the lack of a vertical node below the point of entry and from Abeliella by the differing principle substrate type. Distinguished from all other dendrinids by the presence of the tubular entrance tunnel and/or the general outline of the plexus.Published as part of Wisshak, Max, 2017, Taming an ichnotaxonomical Pandora's box: revision of dendritic and rosetted microborings (ichnofamily: Dendrinidae), pp. 1-99 in European Journal of Taxonomy 390 on page 69, DOI: 10.5852/ejt.2017.390, http://zenodo.org/record/383985
