New Data On Occurrences Of The Devonian Rugose Coral Calceola In Belgium, Anthony J. Wright, M Coen-Aubert, P Bultynck, A P. Van Viersen

Opercula and corallites of Calceola sandalina from the late Eifelian and early Givetian (Middle Devonian) Hanonet Formation of Belgium are illustrated. The few previous illustrations of calceoloid corals from the Devonian of Belgium did not include opercula showing the generically diagnostic morphological features, so for the first time the presence of the genus and species in Belgium is confirmed. One important corallite shows the alar septum and insertion of septa on the external surface of the counter face adjacent to the alar septum.
Late Llandovery (Early Silurian) Dendroid Graptolites From The Cotton Formation Near Forbes, New South Wales, R B. Rickards, Anthony J. Wright, G Thomas
Late Llandovery (Early Silurian) Dendroid Graptolites From The Cotton Formation Near Forbes, New South Wales, R B. Rickards, Anthony J. Wright, G Thomas
Anthony Wright
A well-preserved dendroid graptolite fauna of Early Silurian (late Llandovery: probable turriculatus graptolite zone) age is described from the Cotton Formation near Forbes, New South Wales. A possible rhabdopleuran hemichordate is described from Australia for the fi rst time. The fauna consists of 13 taxa as follows: Dendrograptus sp. aff. D. avonleaensis, Dictyonema zalasiewiczi sp. nov., Dictyonema sp. aff. D. paululum australis, Dictyonema paululum australis, Dictyonema sp. aff. D. sp. cf. D. venustus of Bulman (?ssp. nov.), Dictyonema venustum, Dictyonema sp. cf. D. falciferum, Callograptus bridgecreekensis, Callograptus rigbyae, Callograptus sp. aff. C. ulahensis, Stelechocladia sp. cf. S. praeattenuata, Acanthograptus praedeckeri …
Phylum Arthropoda, Subphylum Trilobitomorpha: Trilobites, Anthony J. Wright, Roger A. Cooper
Phylum Arthropoda, Subphylum Trilobitomorpha: Trilobites, Anthony J. Wright, Roger A. Cooper
Anthony Wright
This volume is the second of three that provide a complete review and inventory of New Zealand's entire living and fossil biodiversity - an international effort involving more than 220 New Zealand and overseas specialists and the most comprehensive of its kind in the world. Together, the three volumes will list every one of the almost 55,000 known species of New Zealand's animals, plants, fungi and micro-organisms. Volume 2 mostly deals with the major branch of the animal kingdom known as Ecdysozoa (moulting animals), which includes arachnids, centipedes and millipedes, crustaceans and insects. It also includes the enigmatic phylum Chaetognatha …

The palaeontology and stratigraphy of the Ordovician if Iran has been the subject of considerable research over the past 15 years, revealing biogeographically significant faunas whose affinities are shared both with peri-Gondwanian terranes and continental blocks. Documentation of the composition and ages of these faunas, many of which are still poorly known, is critical to constraining palaeogeographic reconstructions of the time.
Septal Architecture And Palaeoecology Of Calceola (Cnidaria, Calceolidae), With Comments On The Phylogeny Of Devonian Operculate Tetracorals, Anthony J. Wright
Septal Architecture And Palaeoecology Of Calceola (Cnidaria, Calceolidae), With Comments On The Phylogeny Of Devonian Operculate Tetracorals, Anthony J. Wright
Anthony Wright
In Calceola sandalina the full complement of counter major septa was established very low in the calyx, extending from the counter septum across to the edge of the counter face. At about mid-height of the calyx, a counter-lateral major septum was generated on either side of and from the counter septum. Serial minor septal insertion was initiated adjacent to the counter-lateral septa at a slightly later stage and continued throughout the subsequent ontogeny of the corallite, with minor septa (schizosepta?) arising on the median side of major septa and bifurcating from them. Alar fossulae are seen in the calyx of …
The Asaphid Trilobite Ogygites Collingwoodensis Reed, 1926 From The Late Ordovician Of New Zealand, Anthony J. Wright
The Asaphid Trilobite Ogygites Collingwoodensis Reed, 1926 From The Late Ordovician Of New Zealand, Anthony J. Wright
Anthony Wright
The New Zealand asaphid trilobite Ogygites collingwoodensis is redescribed on the basis of the type material and new collections, and its assignment to Basiliella is confirmed. The species occurs with the trinucleid trilobite Incaia bishopi and graptolites indicative of the Nemagraptus gracilis zone (early Late Ordovician, early Sandbian/Gisbornian), mostly as disarticulated material in intensely bioturbated siltstone of the Douglas Formation. Comparison with coeval faunas is limited due to the low diversity of this fauna, but B. collingwoodensis shows some limited similarity to contemporaneous eastern Australian faunas, whereas Incaia also occurs in South America and South China.

A well preserved Middle Ordovician conodont fauna of 24 species has been recovered from seven samples of a small limestone lens exposed in Thompson Creek, northwest of Nelson, on the South Island of New Zealand. The presence of Histiodella holodentata, Baltoniodus? sp., Paroistodus originalis, P. horridus, Periodon macrodentatus, Protopanderodus sp. cf. P. varicostatus, Costiconus ethingtoni and Venoistodus balticus in the fauna indicates a Darriwilian (late Da2 to mid Da3) age. The occurrence of Ansella jemtlandica, Baltoniodus? sp., Periodon macrodentatus, Spinodus sp., Spinodus? sp. and Histiodella holodentata suggests a relatively deeper water (outer shelf to slope) setting, comparable with contemporaneous faunas, …

A well preserved Middle Ordovician shelly fauna, represented by twelve species of lingulate brachiopods and one trilobite genus, was recovered from an allochthonous limestone lens exposed in Thompson Creek, northwest of Nelson, on the South Island of New Zealand. The stratigraphic setting is unclear as the limestone is situated in the Takaka Terrane adjacent to the Anatoki Fault, separating this terrane from the Buller Terrane. The original depositional environment of the limestone is interpreted as relatively deep water (outer shelf to upper slope). Lingulate brachiopods described include the new species Hyperobolus? thompsonensis sp. nov., Cyrtonotreta robusta sp. nov., Scaphelasma paturauensis …
