Early Permian Jakutoproductus (Productida: Brachiopoda) from Patagonia,Argentina

The productid brachiopod genus Jakutoproductus, dominant in the Early Permian marine faunas of northeastern Siberia, is described for the first time from the southern hemisphere. Jakutoproductus australis sp. nov. is described from the Rio Genoa Formation, Chubut Province (Patagonia), Argentina. The age of the Patagonian species is considered to be Sakmarian (Early Permian), possibly Sterlitamakian.     

New Late Permian rugose corals from Pahang,peninsular Malaysia

Aye Ko Aung, Ng Tham Fatt, Kyaw Kyaw Nyein & Myo Htut Zin, 2013. New Late Permian rugose corals from Pahang, peninsular Malaysia. Alcheringa 37, 422–434. ISSN 0311-5518.

Late Permian rugose corals are described from a limestone unit of the Gua Musang Formation at Selborne Estate, Padang Tengku area, Pahang, peninsular Malaysia. These include one genus, Iranophyllum, which is reported for the first time from Malaysia, with two new species Iranophyllum aequabilis and I. pahangense belonging to Waagenophyllidae. A Late Permian age is confirmed by a Paleofusulina–Colaniella–Reichelina foraminiferal fauna co-preserved with the corals.

Artinskian (Early Permian) fusuline fauna from the Rongma area in northern Tibet: palaeoclimatic and palaeobiogeographic implications

Zhang, Y.C., Wang, Y., Zhang, Y.J. & Yuan, D.X., 2013. Artinskian (Early Permian) fusuline fauna from the Rongma area in northern Tibet: palaeoclimatic and palaeobiogeographic implications. Alcheringa 37, 529–546. ISSN 0311–5518.

A fusuline fauna consisting of ten species in five genera from the Qudi Formation of the Jiaomuri and Gangtangcuo sections in the Rongma area, northern Tibet, is described. This fauna contains a few typical Peri-Gondwanan fusuline species such as Pseudofusulina pamirensis, Neodutkevitchia insignis and N. sp. cf. N. tumidiscula. The fauna is dated as Artinskian based on the presence of both genera Chalaroschwagerina and Praeskinnerella. The Peri-Gondwanan fusuline fauna in the Qiangtang Block is grouped palaeobiogeographically into the Southern Transitional Zone, which is located in the southern part of the Peri-Gondwanan blocks during the late Sakmarian and Artinskian. Moreover, the occurrence of the Peri-Gondwanan fusuline fauna, the lithological transition from glacimarine deposits to carbonates, and the Peri-Gondwanan fusulines’ apparent southeastward migration from the Kalmard Block of central Iran during the Artinskian, are interpreted here to be the result of global warming after the peak of the Late Palaeozoic Ice Age.

A new Late Permian brachiopod fauna from Tanggula,Qinghai-Tibet Plateau and its palaeogeographical implications

Weihong He, Jianjun Bu, Zhijun Niu & Yang Zhang, June, 2009. A new Late Permian brachiopod fauna from Tanggula, Qinghai-Tibet Plateau and its palaeogeographical implications. Alcheringa 33, 113–132. ISSN 0311-5518.

A brachiopod fauna described from the Late Permian of the Gongri and Lizai villages, northwest of the Qoima Co Lake, Tanggula area, southern Qinghai, northwest China, includes ten species in nine genera. This fauna from the (Qiangtang Block) has a strong affinity to coeval faunas of South China, sharing 74% of its species. In addition, the Late Permian Tanggula brachiopod assemblages also demonstrate a clear link with the Middle Permian brachiopod faunas of neighbouring microcontinents including the Indochina block (Malaysia and Cambodia) and the Shan-Thai block (Thailand), as suggested by the presence of Caricula sp. cf. C. salebrosa, Transennatia termierorum and Strophalosiina. This phenomenon indicates that there were relatively narrow seaways between these microcontinents to enable ready interchange of brachiopods during the Permian, and that brachiopods tended to retreat towards the palaeoequatorial region throughout the period.     

Fossil wood of the Mimosoideae from the early Paleocene of Patagonia,Argentina

Brea, M., Zamuner, A.B., Matheos, S.D., Iglesias, A. & Zucol, A.F., December, 2008. Fossil wood of the Mimosoideae from the early Paleocene of Patagonia, Argentina. Alcheringa 32, 427–441. ISSN 0311-5518.

An anatomically preserved mature stem from the Salamanca Formation (early Paleocene) at Palacio de Los Loros, central Patagonia, Argentina, is described and assigned to Paracacioxylon frenguellii sp. nov. The material was preserved by siliceous permineralization and shows features of the secondary xylem typical of subfamily Mimosoideae. This species represents the oldest record of the genus and of the Leguminosae along the western border of Gondwana, and is the world's second oldest record of Leguminosae wood. The species is characterized by ring-porous to semi-ring-porous vessels that are solitary, in multiples of 2–4 and clustered, simple perforation plates, alternate and vestured inter-vessel pitting, homocellular 1–6 seriate rays, tyloses, crystals and diffuse apotracheal, vasicentric paratracheal and confluent axial parenchyma. Paracacioxylon frenguellii has anatomical similarities to Acacia Miller. The presence of Paracacioxylon frenguellii associated with pulvinate leaves suggests that the legumes might have been a component of mesothermal forests developed along the western margin of the Golfo San Jorge Basin during the early Paleocene.     

Evolutionary morphological changes in the new genus Duoforisa: implication for classification and habitat of the unilocular Foraminifera

Qianyu Li & Brian Mcgowran, 1994:03:28. Evolutionary morphological changes in the new genus Duoforisa: implication for classification and habit of the unilocular Foraminifera. Alcheringa 18, 121–134. ISSN 0311-5518.

Unlike other unilocular foraminifera, the new genus Duoforisa from the Late Oligocene to Early Miocene possesses a kidney-shaped test with two apertures on its distal ends. It contains two distinct and successional species, both new, and differentiated by their apertural details. In Duoforisa rima the apertures are slit-like, and become radial in the descendant D. diducta. Intermediate forms have transitional apertural configurations between the slit type and radial type, accompanied also by a change of the test outline from subtriangular to compactly U-shaped. The evolution of the lineage occurred during a period of enhanced upwelling in the Early Miocene and it was terminated just before the global warming at the Early-Middle Miocene boundary. This example suggests evolution of the unilocular foraminifera through successional morphological changes in test shape and in the aperture. Unilocular taxa have tended to flourish or speciate in cool or upwelling environments. Their contraction in the latest Early Miocene to early Middle Miocene was probably due to global warming and well oxygenated conditions which were widespread in the neritic domains of southern Australia.     

Kukulkanus,a new genus of buxtoniin brachiopod from the Artinskian–Kungurian (Early Permian) of Mexico

Torres-Martínez, M.A., Sour-Tovar, F. & Barragán, R., November 2017. Kukulkanus, a new genus of buxtoniin brachiopod from the Artinskian–Kungurian (Early Permian) of Mexico. Alcheringa 42, 268–276. ISSN 0311–5518.

Kukulkanus is the first genus of the tribe Buxtoniini recorded from rocks of the late Cisuralian (Artinskian–Kungurian). The Early Permian (Cisuralian) outcrops of the Santa Rosa Group, from southeastern Chiapas, are one of the most important marine Palaeozoic successions of Mexico. The Artinskian–Kungurian Paso Hondo Formation is the youngest unit in the succession and is dominated by massive limestone. Different marine invertebrates deposited in massive calcareous rocks characterize this formation. The buxtoniin Kukulkanus spinosus gen. et sp. nov. is reported from a single bed within the unit. The outcrops are located in southeastern Chiapas, very near the Guatemala–Mexico border. The lithological features and the preservation of fossils indicate that the fossil-bearing rocks were deposited in a low-energy open-waters paleoenvironment over the continental platform. Fusulinids, cephalopods and brachiopods previously described for the Paso Hondo Formation have been correlated with faunas of different coeval localities from Texas, New Mexico, Coahuila, Chiapas and Venezuela, regions that form part of the biotic Grandian Palaeo-Province.

First record of Homoctenus (Tentaculitoidea,Homoctenida) from the Late Devonian of northwest Peninsular Malaysia

Meor, H.A.H., Yong, A.M., Zakaria, M.Z.Z. & Ghani, A.A., 2.6.2015. First record of Homoctenus (Tentaculitoidea, Homoctenida) from the Late Devonian of northwest Peninsular Malaysia. Alcheringa 39, 550–558. ISSN 0311-5518.

The homoctenid tentaculitoid genus Homoctenus is reported for the first time from Peninsular Malaysia. The fossils derive from the Upper Devonian Sanai Limestone, exposed in the state of Perlis, northwest Peninsular Malaysia. The fossils are closely related to Homoctenus tenuicinctus tenuicinctus and are described as Homoctenus sp. cf. H. tenuicinctus. The homoctenids were recovered from an interval containing a rich conodont assemblage, indicating a Frasnian age (Palmatolepis linguiformis Zone).

Fixation of the type species of the genus Protoretepora de Koninck, 1878 (Bryozoa,Fenestrata)

Wyse Jackson, P.N., Reid, C.M. & McKinney, F.K., iFirst article, 2011. Fixation of the type species of the genus Protoretepora de Koninck, 1878 (Bryozoa, Fenestrata). Alcheringa, 1–2. ISSN 0311-5518.

The type species of the Palaeozoic bryozoan genus Protoretepora de Koninck, 1878 was originally fixed as Fenestella ampla Lonsdale in Darwin, 1844, but this taxon has been shown to belong to the bryozoan genus Parapolypora Morozova & Lisitsyn, 1996 Morozova, I. P. and Lisitsyn, D. V. 1996. Revision of the genus Polypora. Paleontologicheskii Zhurnal, 1996(4): 38–47. [English translation: Paleontological Journal30(5), 530–541] [Google Scholar]. The original type species designation for Protoretepora de Koninck, 1878 is set aside, and in accordance with Article 70.3 of the International Code of Zoological Nomenclature (4th edition, 1999) the nominal species Protoretepora crockfordae Wyse Jackson, Reid & McKinney, 2011 from the Permian of Tasmania, Australia is herein fixed as the type species.     

Rariellidae,a new family of Rhynchoporoidea (Brachiopoda) with a restudy of the type genus Rariella Zhang 1981, from the Emsian (Early Devonian) of Inner Mongolia,north China

Rong Jla-yu & Zhang Yan. 1994:03:28. Rariellidae, a new family of Rhynchoporoidea (Brachiopoda) with a restudy of the type genus Rariella Zhang 1981. from the Emsian (Early Devonian) of Inner Mongolia, north China. Alcheringa 18. 135–146. ISSN 0311-5518

Reinvestigation of the type material of Rariella Zhang 1981, from the late Emsian (Early Devonian) of western Inner Mongolia, north China, shows that it should be attributed to the rhynchoporoids rather than the retziids since it possesses a punctate shell without laterally directed spiralia and lacks evidence for the brachiophore supports being in the fonn of a loop, as in the terebratuloids. A new family Rariellidae based on Rariella as the type genus is characterized by a spondylium apically in the pedicle wlve and a cardinal process on a septalium in the brachial valve. The fauna containing Rariella is mainly endemic to Inner Mongolia and developed at depths within Benthic Assemblage 2 to inner BA 3.     

Late Triassic megaspores from the Amery Group,Prince Charles Mountains,East Antarctica

Cantrill, D. J., & Drinnan, A. N., 1994:03:28. Late Triassic megaspores from the Amery Group, Prince Charles Mountains, East Antarctica. Alcheringa 18, 71–78. ISSN 0311-5518.

Megaspores referable to the genera Cabochonicus Batten & Ferguson 1987 and Minerisporites Potonié 1956 are a common component of the palaeoflora recovered from the Jetty Member within the Flagstone Bench Formation of the Amery Group. The known ranges of these two genera, in conjunction with the macrofloral remains, suggest a Late Triassic age. Two new species, Cabochonicus sinuosus and Minerisporites triangulatus, are described. Scanning electron microscopic examination of the spores indicates that standard palynological treatment of megaspores can result in sculptural degradation, possibly leading to incorrect generic assignment.     

Palaeoecology and Archaeology of the Village of Uukuniemi,Eastern Finland

Abstract

In the present article, pollen analytical results from Lake Kirkkolampi are presented and compared with results provided by archaeological material. Pollen analysis is connected with the archaeological research project at Papinniemi in Uukuniemi. Papinniemi is one of the numerous Greek Orthodox settlements that existed in Karelia in the fourteenth to seventeenth centuries. Archaeological evidence of settlement preceding this period is very scarce, and in this respect Uukuniemi represents a typical area in eastern Finland. There is no archaeological evidence of permanent settlement in Uukuniemi from the Early Metal Period (c. 1800 bc–ad 400), the Middle Iron Age (c. ad 400–800) or from the Late Iron Age (c. ad 800–1300). Pollen analysis demonstrated the onset of cultivation c. cal ad 300. Marked intensification of agricultural activities and cultivation in permanent fields took place around cal ad 800. A shift in land-use practises, including a declining use of fire, is visible at cal ad 1520–1600. The discrepancy between archaeological and palaeoecological records raises several questions, and the problems of Early Metal Period and Iron Age populations, as well as settlement continuity, are discussed.     

The Temple of the Fishermen: Early Ceremonial Architecture at Gramalote,a Residential Settlement of the Second Millennium B.C., North Coast of Peru

The archaeology of the Late Preceramic (3500–1800 b.c.) and Initial Periods (1800–800 b.c.) on the north coast of Peru is focused on monumental ceremonial buildings and little attention has been paid to small residential settlements. Here, I introduce the excavations carried out at Gramalote, a fishing settlement that was interpreted as a specialized producer of seafood with a narrow range of non-subsistence activities. Current data support a broader view of fishing communities during the second millennium b.c. in northern Peru. In this view, the discovery of a ceremonial facility at the Gramalote site opens a discussion about the role of community-level ceremonies and how these local practices are related to those at religious monumental centers of the same period.     

New material from the Ordovician of China indicates that Inocaulis is a graptolite

The problematic Early Palaeozoic fossil Inocaulis has been regarded as an alga, a graptolite and a hydroid by different authors. A new specimen from the Ordovician (late Darriwilian) of Guizhou Province (China) shows fusellar banding, confirming that it is a benthic graptolite.

Agricultural production in the Central Asian mountains: Tuzusai,Kazakhstan (410–150 b.c.)

Abstract

The site of Tuzusai is located in the Tien Shan Mountains of eastern Kazakhstan; occupation at the site between 410 B.C. and a.d. 150 represents the transition between the Saka and Wusun periods (Saka: 800–200 b.c.; Wusun: 200 b.c.–a.d. 400). Iron Age people of Central Asia are often described simply as mobile pastoralists, yet at Tuzusai, we have evidence that agriculture was practiced along with pastoral transhumance. This multiresource economic system combined pastoralism and hunting with the cultivation of a variety of crops. Our new finding is significant because Tuzusai has the first clear evidence for the presence of agriculture from the Iron Age of northern Central Asia. The diversity of crops grown at Tuzusai required varying labor and time inputs and a well-planned scheduling system.     

New material referable to Wakaleo (Marsupialia: Thylacoleonidae) from the Riversleigh World Heritage Area,northwestern Queensland: revising species boundaries and distributions in Oligo/Miocene marsupial lions

Gillespie, A.K., Archer, M., Hand, S.J. & Black, K.H., 2014. New material referable to Wakaleo (Marsupialia: Thylacoleonidae) from the Riversleigh World Heritage Area, northwestern Queensland: revising species boundaries and distributions in Oligo/Miocene marsupial lions. Alcheringa 38, 513–527. ISSN 0311–5518.

New material of Wakaleo oldfieldi and W. vanderleueri from the Miocene freshwater limestones of the Riversleigh World Heritage Area, northwestern Queensland, is described. This material includes the first known upper dentition of W. oldfieldi and dentaries of both species bearing the previously undescribed and morphologically distinct M₃. Previously, the two species were distinguished only by size differences in P3 and the size of P₃ relative to M1. Wakaleo oldfieldi exhibits a more plesiomorphic M₃ that retains a well-developed talonid basin in contrast to W. vanderleueri, which has lost this structure. The phyletic succession and geological occurrences of Wakaleo species make this genus an important taxon in biochronological analyses of Australian Cenozoic assemblages. At Riversleigh, W. oldfieldi is found in deposits allocated to Faunal Zone B and Faunal Zone C, which are regarded as early and middle Miocene in age, respectively. The presence of this species in the Kutjamarpu Local Fauna of central Australia suggests that fauna may be of a similar age. Broader faunal correlations have suggested Faunal Zone C correlates with the middle Miocene Bullock Creek Local Fauna, which contains the more derived W. vanderleueri. Based on stage-of-evolution arguments, W. oldfieldi should occur in older deposits than those yielding W. vanderleueri. The presence of both species of Wakaleo in Faunal Zone C assemblages at Riversleigh suggests that current presumptions about the contemporaneity of the many Faunal Zone C Sites should be examined more rigorously.

Emwadea microcarpa gen. et sp. nov.—anatomically preserved araucarian seed cones from the Winton Formation (late Albian), western Queensland,Australia

Dettmann, M.E., Clifford, H.T., Peters, M., June 2012. Emwadea microcarpa gen. et sp. nov.—anatomically preserved araucarian seed cones from the Winton Formation (late Albian), western Queensland, Australia. Alcheringa, 217–237. ISSN 0311-5518.

A new genus and species, Emwadea microcarpa Dettmann, Clifford & Peters, is established for ovulate/seed cones with helically arranged cone scales bearing a centrally positioned, inverted ovule from the basal Winton Formation (late Albian), Eromanga Basin, Queensland. The cones are small, prolate ellipsoidal (9.5–14 mm vertical axis, 6.3–8.7 mm transverse axis) with wedge-shaped cone scales bearing winged seeds attached adaxially to the scale only by tissues surrounding the vasculature entering the ovule. Ovuliferous tissue that is free from the cone scale extends distally from the chalaza; the seeds' lateral wings are derived from the integument. Foliage attached to the cones is spirally arranged, imbricate and with spreading and incurved bifacial blades with acute tips; stomata are arranged in longitudinal files and are confined to the adaxial surface. The cone organization testifies to placement within the Araucariaceae, and is morphologically more similar to Wollemia and Agathis than to Araucaria.

A new Late Silurian plant with complex branching from Xinjiang,China

Wang Yi, Fu Qiang, Xu Honghe, & Hao Shougang, June, 2007. A new Late Silurian plant with complex branching from Xinjiang, China. Alcheringa 31, 111-120. ISSN 0311-5518.

A new fossil plant is described from the middle part of the Wutubulake Formation (late Pridoli) of Xinjiang, China. This plant demonstrates at least two orders of branching. The first-order axis has pseudomonopodial branching with alternately attached second-order axes. Fertile units are alternately inserted along the second-order axis, and consist of a branching system and two sporangia at each tip. Sporangia are narrowly obovate with rounded apex and tapering base. This plant is characterized by more complex branching than other Silurian and Early Devonian plants, and is named Wutubulaka multidichotoma gen. et sp. nov., and placed under open higher-order nomenclature.
