Four new genera and five new species of anaxyelids are described from the Cretaceous of Asia: Mangus magnus gen. et sp. nov. from the Aptian of Mongolia (Bon-Tsagan), Urosyntexis undosa sp. nov., Parasyntexis khasurtensis gen. et sp. nov., both from the Early Cretaceous of Transbaikalia (Khasurty), Dolichosyntexis transbaikalicus gen. et sp. nov. from the Hauterivian–Barremian of Transbaikalia (Baissa), and Curiosyntexis magadanicus gen. et sp. nov. from the mid-Upper Cretaceous of NE Siberia (Obeshchayushchiy). Early Cretaceous is the time of the highest diversity of Anaxyelidae. In this epoch these sawflies are represented with all four subfamilies comprising the group. In Late Cretaceous anaxyelid diversity and abundance rapidly decrease and they are represented with the only subfamily Syntexinae. The anaxyelid collection of Palaeontological Institute (Moscow), the most representative collection of fossil anaxyelids in the world, has been completely revised, identified and described. The list of identifications is provided.

The Ul’ya flora comes from the Coniacian volcanogenic deposits of the Amka Formation (the Ul'ya depression, southern part of the Okhotsk-Chukotka volcanogenic belt). Ginkgoaleans are diverse in this flora and represented by three genera: Ginkgo, Sphenobaiera and Baiera. All specimens have no cuticle and were assigned to morphotaxa. Genus Ginkgo includes two species: G. ex gr. adiantoides (Ung.) Heer with entire leaves and G. ex gr. sibirica Heer with dissected leaves. Genus Sphenobaiera also consists of two species: S. ex gr. longifolia (Pom.) Florin with 4–8 leaf lobes and S. ex gr. biloba Prynada with two leaf lobes. Genus Baiera is represented by new species B. lebedevii Golovn., sp. nov.Leaves of this species are 25–30 cm long and 13–16 cm wide, narrowly wedge-shaped with flat slender petiole, dichotomously dissected 4–5 times into linear segments 3–6 mm wide with 6–12 veins. The length of ultimate segments is equal to about a half of leaf length. Leaves attached spirally to ovoid short shoots about 2 cm long. Among the Late Cretaceous floras similar diversity of ginkgoaleans was recorded only in the Turonian-Coniacian Arman flora from middle part of the Okhotsk-Chukotka volcanogenic belt (Herman et al., 2016). Four species of ginkgoaleans from the Ul’ya flora (except G. ex gr. adiantoides) are considered as the Early Cretaceous relicts.

Marine Fossils

Localities and deposits in north-west Nûgssuaq yielding fossil corals of the order Scleractinia are described. The age of the corals is Campanian?, Maastrichtian and Lower Paleocene (Danian), on the basis of other marine fossils. 22 species are considered; 7 are described as new and are indigenous, 2 are possibly North American forms, 3 are known from Europe, and 10 are identifiable only to generic level. The following genera and subgenera are represented: Haimesiastraea (Haimesiastraea), H. (Perupiastrea)?, Discotrochus?, Astrangia (Coenangia)?, Oculina, Caryophyllia, Trochocyathus, Paracyathus, Stephanocyathus (Stephanocyathus), Desmophyllum?, Lophelia?, Parasmilia, Flabellum, Balanophyllia, and Dendrophyllia . In addition, two new genera are described: Kangiliacyathus and Faksephyllia . Certain Danian corals from Scandinavia are also revised. In a survey of habitats, the lithology of the corallocalities is considered together with bathymetric and thermal ranges known for scleractinian genera and species from other parts of the world. Depth and temperature of the Campanian and Maastrichtian seas in Greenland cannot be estimated with any accuracy. The Lower and Upper Danian seas were generally rather shallow. There is little evidence on which to judge the Danian climate. Two species were perhaps hermatypic (no reef structures have been found). The remaining scleractinians are presumed to have been ahermatypic. A non-reef coral association has been found. Lower Danian rather sparsely populated polytypic coral thickets show signs of continual disturbance from water turbulence. The approximate depth of formation of these thickets appears to have been 80 m or shallower, which appears to be less than is usual for coral structures of this type. Some Lower Paleocene species provide conclusive evidence of a direct connection between the Danian seas of West Greenland and of Scandinavia.

Many Cretaceous asymmetrical rhynchonellid brachiopods (Brachiopoda, Rhynchonellida) have long been considered as Rhynchonella difformis (Valenciennes in Lamarck, 1819). After a revision, Owen (1962) included the Cenomanian specimens from Europe in Cyclothyris M’Coy, 1844. Later, Manceñido et al. (2002) confirmed this decision and critically mentioned the name of another asymmetrical rhynchonellid genus from Spain, Owenirhynchia Calzada in Calzada and Pocovi, 1980. Specimens with an asymmetrical anterior margin (non particularly ecophenotypical), from the Late Coniacian and the Santonian of Les Corbières (Aude, France) and Basse-Provence (SE France) are here compared to specimens of the original Cenomanian species C. difformis. They are also compared to new material from the Northern Castilian Platform (Coniacian-Santonian, N Spain) and to Rhynchonella globata Arnaud, 1877 (Campanian, Les Charentes, Dordogne, SW France) and Rh. vesicularis Coquand, 1860 (Campanian, Charente, SW France). These observations document the great morphological diversity among all these species and lead us to erect a new species: Cyclothyris grimargina nov. sp. from the type material of Arnaud, and two new genera: Contortithyris nov. gen. including Contortithyris thermae nov. sp., Beaussetithyris nov. gen. including Beaussetithyris asymmetrica nov. sp. All of these brachiopods fundamentally present an asymmetrical state which origin is discussed.

Close Relatives

Despite the increasing number of exceptional feathered fossils discovered in the Late Jurassic and Cretaceous of northeastern China, representatives of Ornithurae, a clade that includes comparatively-close relatives of crown clade Aves (extant birds) and that clade, are still comparatively rare. Here, we report a new ornithurine speciesChangzuiornis ahgmifrom the Early Cretaceous Jiufotang Formation. The new species shows an extremely elongate rostrum so far unknown in basal ornithurines and changes our understanding of the evolution of aspects of extant avian ecology and cranial evolution. Most of this elongate rostrum inChangzuiornis ahgmiis made up of maxilla, a characteristic not present in the avian crown clade in which most of the rostrum and nearly the entire facial margin is made up by premaxilla. The only other avialans known to exhibit an elongate rostrum with the facial margin comprised primarily of maxilla are derived ornithurines previously placed phylogenetically as among the closest outgroups to the avian crown clade as well as one derived enantiornithine clade. We find that, consistent with a proposed developmental shift in cranial ontogeny late in avialan evolution, that this elongate rostrum is achieved through elongation of the maxilla while the premaxilla remains only a small part of rostral length. Thus, only in Late Cretaceous ornithurine taxa does the premaxilla begin to play a larger role. The rostral and postcranial proportions ofChangzuiornissuggest an ecology not previously reported in Ornithurae; the only other species with an elongate rostrum are two marine Late Cretacous taxa interpreted as showing a derived picivorous diet.

New System

A new system of nomenclature is proposed with the purpose of presenting a scheme which will be applicable to spores, pollens, and other microfossils from all geological ages. A review of previous nomenclatural systems is presented to indicate the historical development of microfossil nomenclature. The applicability of the new system is illustrated by naming 21 new species and four new genera of Upper Cretaceous microfossils from the Comox formation of Vancouver Island and the Oldman formation of southern Alberta. The microfossil conspecti are briefly compared with the assemblage previously reported from the Brazeau formation of western Alberta. Advantages of the new nomenclatural scheme are discussed in the light of future discoveries of plant microfossils, and their application to palaeobotanical and geological problems.

Water Surfaces

Water striders and their allies (Hemiptera, Gerromorpha) are familiarinhabitants of water surfaces throughout the world. One of the mostspecies-rich groups is the subfamily Microveliinae (Veliidae) that comprisessmall or very small bugs inhabiting the nearshore areas of stagnant orslow-flowing freshwater. Accumulation of material during the past 30 years hasshown that the Australian fauna of Microveliinae is much richer and morediverse than previously recognised. In the present paper we discuss thegeneric classification of the subfamily and describe three new genera forspecies previously classified in the genus MicroveliaWestwood as well as three other new genera and nine new species. The new taxaare: Drepanovelia, gen. nov. (type-species:Microvelia dubia Hale),D. millennium (NSW, Queensland),D. biceros (NSW), and D. nielseni(Queensland) spp. nov., Lacertovelia hirsuta, gen. etsp. nov.

Eutaw Formation

This paper describes new species of Ostracoda from Late Cretaceous (late Santonian) oyster reefs of the Eutaw Formation of eastern Alabama. The reefs are composed almost exclusively of Ostrea cretacea Morton, with rarer occurrences of the oysters Exogyra upatoiensis Stephenson and Lopha ucheensis (Stephenson) and the bivalve Anomia preolmstedi Stephenson. Total thickness of the reefs is about 30 m, and the reefs are a major topographic feature across most of Macon and Russell Counties, Alabama, a distance of about 60 km. The reefs are interpreted to have been backbarrier sediments deposited under brackish conditions.Eight species of ostracodes are identified, including five new species described herein. The fauna is typically well preserved, and includes males, females, and juveniles. New species include Haplocytheridea? eutawensis, Antibythocypris dimorphicus, A. nephotrema, Brachycythere asymmetrica, and Eocytheropteron mutafoveata. Also discussed and illustrated are Cytherella tuberculifera Alexander, Haplocytheridea renfroensis renfroensis Crane, and Fissocarinocythere gapensis (Alexander).

A New Species

In the past, various authors have placed many species in genera that are now understood to be restricted to other regions of the world. Thus, in Africa, species of soft scale (Hemiptera: Sternorrhyncha: Coccomorpha: Coccidae) with this problem are those in Ceronema Maskell, a genus probably restricted to Australia; Ceroplastodes Cockerell, probably restricted to the New World; and Inglisia Maskell, which is restricted to New Zealand. The placement of these species is reviewed here. Four of the known Ceronema species are placed in three new monotypic genera, Neoceronema gen. nov., Illovococcus gen. nov. and Bugandacoccus gen. nov., as Neoceronema africanum (Macfie) comb. nov., N. brachystegiae (Hall) comb. nov., Illovococcus mobilis (Brain) comb. nov. and Bugandacoccus gowdeyi (Newstead) comb. nov.; Ceroplastodes ritchiei Laing and C. zavatarii Bellio are transferred to Drepanococcus Williams & Watson, as D. ritchiei (Laing) comb. nov. and D. zavattarii (Bellio), comb. nov., and Inglisia grevilliae Hall, I. pluvialis Hodgson and I. theobromae Newstead are transferred to Cryptinglisia Cockerell as C. grevilliae (Hall) comb. nov., C. pluvialis (Hodgson) comb. nov. and C. theobromae (Newstead) comb. nov. Keys are provided to all Drepanococcus and Cryptinglisia species, and all the African species discussed are illustrated. In addition, another new genus of African Coccidae is described, Testudovestis gen. nov., to take a new species somewhat similar to Eucalymnatus Cockerell: T. africana spec. nov. In addition, a new species of Coccus L.: Coccus moorei, spec. nov., and a new species of mealybug (Heliococcus tinglei spec. nov., Pseudococcidae), are described, both from mainland Africa. The lecanodiaspid Lecanodiaspis zygophylli Hodgson is also recorded from Nigeria for the first time.

A new species of carcineretid crab, Carcineretesplanetarius, is described from the Upper Cretaceous (lower Maastrichtian) Barton Creek Dolomite at Albion Island, Belize. The age is based on the stratigraphic range of associated nerineid gastropods and correlation with nannoplankton, benthic foraminifera, and the other known congeneric species of crab found in Jamaica. Confirmation of this age aids in constraining the timing of ejecta deposits of the Chicxulub impact found at the top of Barton Creek Dolomite exposed on Albion Island. Paleoenvironmental and paleoecological analyses suggest that these crabs were swimmers in lagoonal settings, capable of burrowing a few centimeters into the mud for protection.
