AbstractThe problematic calcified cnidarian Cambroctoconus is described from the Henson Gletscher Formation (Cambrian Series 2, Stage 4–Series 3, Stage 5) of North Greenland, representing the first record from Laurentia of a genus otherwise recently described from China, Kyrgyzstan, and Korea. Internal molds produced by penetrative phosphatization mirror the pervasive pore system of the calice walls and septa. The pore system is compared to the network of gastrodermal solenia that distributes nutrients between polyps and surrounding stolon tissues in present day octocorals. In conjunction with the octagonal form of the individual coralla and eight-fold symmetry of septa, the pore system promotes assignment of Cambroctoconus to the Octocorallia, a basal clade in cnidarian phylogeny. Octocorals (‘soft corals’) are diverse in present day seas, but have a poor fossil record despite the general development of distinctive calcareous spicules. New taxa: Order Cambroctoconida new; Cambroctoconus koori new species.

AbstractAn assemblage of 50 species of small shelly fossils is described from Cambrian Series 2 (Stage 4) strata in North Greenland, the present day northernmost part of the paleocontinent of Laurentia. The fossils are derived from the basal member of the Aftenstjernesø Formation at Navarana Fjord, northern Lauge Koch Land, a condensed unit that accumulated in a sediment-starved outer ramp setting in the transarctic Franklinian Basin, on the Innuitian margin of Laurentia. Most other small shelly fossil assemblages of similar age and composition from North America are described from the Iapetan margin of Laurentia, from North-East Greenland south to Pennsylvania. Trilobites are uncommon, but include Serrodiscus. The Australian bradoriid Spinospitella is represented by a complete shield. Obolella crassa is the only common brachiopod. Hyoliths, including Cassitella, Conotheca, Neogloborilus, and Triplicatella, are abundant and diverse, but most are represented just by opercula. Sclerites interpreted as stem-group aculiferans (sachitids) are conspicuous, including Qaleruaqia, the oldest described paleoloricate, Ocruranus?, Inughuitoconus n. gen., and Hippopharangites. Helcionelloid mollusks are diverse, but not common; they are associated with numerous specimens of the bivalve Pojetaia runnegari. The fauna compares best with that of the upper Bastion Formation of North-East Greenland, the Forteau Formation of western Newfoundland, and the Browns Pond Formation of New York, but several taxa have a world-wide distribution. Many specimens are encrusted with crystals of authigenic albite. New species: Anabarella? navaranae, Stenotheca? higginsi, Figurina? polaris, Hippopharangites groenlandicus, Inughuitoconus borealis, and Ocruranus? kangerluk.UUID: http://zoobank.org/160a17b1-3166-4fcf-9849-a3cabd1e04a3

AbstractPhosphatic sclerites of the problematicTarimspiraYue and Gao, 1992 (Cambrian Series 2) recovered by weak acid maceration of limestones display a unique range of mainly strongly coiled morphologies. They were likely organized into multielement scleritomes, but the nature of these is poorly known; some sclerites may have had a grasping function.Tarimspirasclerites grew by basal accretion in an analogous fashion to younger paraconodonts (Cambrian Series 3–4) but lack a basal cavity. Based on proposed homologies,Tarimspiramay provide an extension of the early vertebrate paraconodont–euconodont clade back into the early Cambrian.Tarimspirais described for the first time from Laurentia (North Greenland), extending its known range from China and Siberia in Cambrian Series 2. In addition to the type species,Tarimspira planaYue and Gao, 1992, the Greenland record ofTarimspiraincludes two morphotypes of a new species,Tarimspira artemi.UUID:http://zoobank.org/c7c536c8-cdaf-49a9-ae1d-77c392f553fc.

Abstract The beetle Ceutorhynchus is used as a proxy for Eocene core Brassicaceae. The age of Brassicaceae has been strongly debated because their fossil record is scanty. There are four species of Ceutorhynchus inaffectatus species-group known in the Priabonian: Ceutorhynchus zerovae new species in Rovno amber and three in Baltic amber. There are numerous extant members of the group, all of which feed on core Brassicaceae. Together with differentiation of Brassicaceae-feeding Pierinae (Lepidoptera) in the Priabonian, the strong presence of Ceutorhynchus indicates at least an early Priabonian age of core Brassicaceae. The oldest fossil Brassicaceae is not known in the late Eocene of Europe, but was recorded in Montana, dated in some studies as late Oligocene, but recently as Priabonian (34 Ma). Ceutorhynchus zerovae n. sp. is very close to C. electrinus from Baltic amber. UUID: http://zoobank.org/7f10761f-463d-44c5-9eef-bb4697bfb116.

A New Species

We describe a new species of homolid crab from the Ypresian (early Eocene) Roda Formation of Huesca province (Aragon, Spain). In spite of the fragmentary condition of the sole specimen, some preserved frontal elements, and in particular the complete left cheliped, allow inclusion it within the genus Paromola Wood-Mason in Wood-Mason and Alcock, 1891, based on morphological similarities with the extant species of this genus. Direct comparison with specimens of the extant Paromola cuvieri (Risso, 1815) confirms this systematic assignment. Paromola bretoni n. sp. is the first homolid reported in the Cenozoic of the Iberian Peninsula, and expands the rich decapod fossil record of the Eocene basins of southern Pyrenees.

Fossil Genus

The genus Reissa Evenhuis & Báez in Greathead & Evenhuis (2001) was originally described based on a short series of extant specimens from the island of Tenerife in the Canary Islands. No further species of the genus have been discovered since. A related fossil genus (Riga Evenhuis) was described from Eocene Rovno amber (Evenhuis, 2013) and has some characters in common with the fossil specimen but differs in thoracic and antennal features. The new species described and illustrated here is represented by a single compression fossil of the new species Reissa kohlsi sp. nov. from the Parachute Creek member of the Green River Formation of Wyoming/Utah/Colorado, USA, the site of which dates from 51.2–48.7 my (Smith et al., 2008). It marks the first fossil record of the genus and its first record from the New World, and the first fossil record of the family Mythicomyiidae from North America. The family was previously known in the New World fossil record from the Miocene Dominican amber (cf. Evenhuis, 2013), including two representatives from the Mythicomyiinae (Mythicomyia dominicana Evenhuis, 2002 and Pieza dominicana Evenhuis, 2002).

Charadriiform Bird

A new species, Cherevychnavis umanskae sp. nov., (Aves: Charadriiformes) from the late Miocene of Ukraine is described, and all known fossils of the suborder Charadrii from the Paleogene and Miocene are summarized. The combination of preserved characters allows us to assign the new species to the suborder Charadrii but its more exact systematic position remains uncertain. Morphologically, the new species is most similar to the extant Haematopus and Recurvirostra, and in terms of size to Haematopus, but it clearly differs from all extant genera of Charadrii. The current remains fill the temporal and spatial gaps in the fossil record of charadriiform birds; they constitute the first record of the Charadrii in eastern-most Europe, and add to our still insufficient knowledge of the late Miocene birds.

AbstractHere we record the occurrence of a new species of the Herefordshire Lagerstätte ostracod genusPaulinefrom the Lower Silurian (upper Telychian) of North Greenland.Pauline nivisissp. nov. was recovered from a limestone boulder (Pentamerus Bjerge Formation) collected south of Kap Schuchert, Washington Land. It is reasonable to transpose the palaeobiology known from the HerefordshirePauline avibella– body, limbs including swimming antennae, lateral eyes, gills and alimentary system – into the carapace of the Greenland species, which represents the oldest cylindroleberidid myodocopid and almost the oldest known myodocope, and is the first record of a Herefordshire Lagerstätte genus from outside the Welsh Borderland locality. Morphological, sedimentological and faunal evidence suggest that the Greenland species was nektobenthic. This is compatible with the notion that ostracods (specifically myodocopids) did not invade the water column until later in the Silurian, in the Wenlock and Ludlow epochs.Paulineis an Early Silurian link between ‘Baltic-British’ and North Laurentian ostracod faunas, endorsing the idea that the UK and Greenland were in close geographical proximity, near a remnant Iapetus Ocean, during late Llandovery time.
