Abstract. A complete morphological description, as preservation permits, is provided for a new Late Jurassic fish species (Tharsis elleri) together with a revision and comparison of some morphological features of Tharsis dubius, one of the most common species from the Solnhofen limestone, southern Germany. An emended diagnosis of the genus Tharsis – now including two species – is presented. The new species is characterized by a combination of morphological characters, such as the presence of a complete sclerotic ring formed by two bones placed anterior and posterior to the eye, a moderately short lower jaw with quadrate-mandibular articulation below the anterior half of the orbit, caudal vertebrae with neural and haemal arches fused to their respective vertebral centrum, and parapophyses fused to their respective centrum. A phylogenetic analysis based on 198 characters and 43 taxa is performed. Following the phylogenetic hypothesis, the sister-group relationship Ascalaboidae plus more advanced teleosts stands above the node of Leptolepis coryphaenoides. Both nodes have strong support among teleosts. The results confirm the inclusion of Ascalabos, Ebertichthys and Tharsis as members of this extinct family. Tharsis elleri n. sp. (LSID urn:lsid:zoobank.org:act:6434E6F5-2DDD-48CF-A2B1-827495FE46E6, date: 13 December 2018) is so far restricted to one Upper Jurassic German locality – Wegscheid Quarry near Schernfeld, Eichstätt – whereas Tharsis dubius is known not only from Wegscheid Quarry, but also from different localities in the Upper Jurassic of Bavaria, Germany, and Cerin in France.

Two New Species

A new genus and two new species of fossil Elateridae are described and illustrated: Paralithomerus gen. nov., P. exquisitus sp. nov, and P. parallelus sp. nov. Both species were collected from the Late Jurassic-Early Cretaceous Yixian Formation of western Liaoning, China. Fossil elaterids expressing a sutured mesoventrite have been otherwise discovered only from the Upper Jurassic strata of Karatau.

Abstract. At present the ostracod faunas from the Upper Jurassic of southern Germany are incompletely known due to the absence of detailed studies. This preliminary systematic investigation has yielded 46 species from 25 genera, of which 23 species are left in open nomenclature, while 4 are new species: Bythoceratina (Praebythoceratina) danuvensis, Nemoceratina (Pariceratina) urlichsi, Pokornyopsis punctata and Quasihermanites spiralus. Diversity increases through the late Jurassic with 16 species in the Oxfordian, 19 species in the Kimmeridgian, and 23 species in the Tithonian. Endemism is lowest in the Oxfordian, while highest in the Kimmeridgian.

Twenty-six samples from the Middle and Upper Jurassic strata of Jameson Land were prepared; twenty-one of these were found to contain organic-walled microplankton, of which seventeen yielded assemblages worthy of detailed examination. A new genus (Ambonosphaera) and six new species (Sentusidinium myriatrichum, Sentusidinium pelionense, Ellipsoidictyum gochtii, Pareodinia brachythelis, Gonyaulacysta birkelundii, and Ambonosphaera calioviana) of dinoflagellates, and two new species of acritarchs (Veryhachium sortehatense and Solisphaeridium ankyleton) were discovered. One taxon, Gonyaulacysta pectinigera, is elevated from subspecific to specific level and its generic reallocation is proposed. Samples from the Sortehat and Pelion Members of the Vardekløft Formation and from the Olympen formation yielded poor assemblages in terms of the number of taxa present and are therefore not especially biostratigraphically useful. However, previous Bajocian and Lower Oxfordian dates for the Sortehat Member and Olympen Formation respectively are supported. Moderately rich assemblages from some samples from the Fossilbjerget Member of the Vardekløft Formation and from the Hareelv Formation indicate Bathonian--Callovian and Oxfordian-Kimmeridgian ages respectively. Two samples, one from each of these units, contain organic-walled microplankton assemblages indicative of a date approximately one half stage earlier than that derived from ammonite faunas. All but one of the samples prepared from the Raukelv Formation contain only carbonized organic remains. One sample, from the Fynselv Member, yielded an assemblage of organic-walled microplankton which, although not conclusive themselves in suggesting a date, do not contradict the latest Jurassic assignation based on ammonite faunas.

Protopiceoxylon Gothan, a genus of Mesozoic wood, is reviewed with special emphasis on three North American species. Two new species of this genus are proposed. These are Protopiceoxylon resiniferous from the Upper Jurassic Morrison Formation of Utah and Protopiceoxylon canodense from the Upper Jurassic strata of British Columbia. Protopiceoxylon dacotense from the Lower Cretaceous(?) of South Dakota is redescribed. All species of Protopiceoxylon are compared as to their xylotomy and distribution. Nine species are considered valid. The combination of characters unique for this genus includes the occurrence of only vertically formed resin canals, abietinoid pitting of the rays, and relatively large diameter of the bordered pits on the radial walls of the tracheids. Affinity of the genus with extant Keteleeria is also considered.

AbstractTwo new species of Kalligrammula Handlirsch, 1919 (Insecta, Neuroptera, Kalligrammatidae) are described as K. lata n. sp. and K. karatensis n. sp. based on two nearly complete hindwings respectively from the Middle–Upper Jurassic of Daohugou, China and the Upper Jurassic of Karatau, Kazakhstan. Limnogramma Ren, 2003 is considered to be a junior synonym of Kalligrammula based on the hindwing venation. The distribution of kalligrammatid genera is discussed.
