New Diagnosis

Maurotarion Alberti, 1969, is a diverse otarionine clade that can be readily distinguished from Harpidella M'Coy, 1849. Both genera appear in the Upper Ordovician and range until the Middle Devonian. A new diagnosis for each taxon is given. New species of the genera from the Ordovician and Silurian of the central Mackenzie Mountains, Northwest Territories, Canada, include Harpidella kurrii (Ashgill), H. tikkaneni (Llandovery), H. greggi (Wenlock), and Maurotarion messieri (Llandovery). Harpidella megalops (M'Coy, 1846), H. triloba (Hu, 1975), H. spinafrons (Williams in Cooper and Williams, 1935), Maurotarion struszi (Chatterton, 1971), and M. instita (Whittington and Campbell, 1967) are revised.

A New Species

The genus Nadiastrophia previously recorded only from Australia and China, is described from the Headless Formation of the Mackenzie Mountains. This discovery further emphasizes the early Middle Devonian faunal affinities between the Cordilleran and southeastern Pacific regions. The Mackenzie Mountains Nadiastrophia is assigned to a new species, N. mackenziensis.

A New Species

AbstractThe order Intejocerida is an enigmatic, short-lived cephalopod taxon known previously only from Early–Middle Ordovician beds of Siberia and the United States. Here we report a new genus, Cabaneroceras, and a new species, C. aznari, from Middle Ordovician strata of central Spain. This finding widens the paleogeographic range of the order toward high-paleolatitudinal areas of peri-Gondwana. A curved conch, characteristic for the new genus, was previously unknown from members of the Intejocerida.UUID: http://zoobank.org/21f0a09c-5265-4d29-824b-6b105d36b791

Generic Description

Podosordaria Ellis et Holw. is used for those members of the Xylariaceae possessing stalkedor sessile stromata in the form of mammillate heads with erumpent ascocarps, containing whitish internal tissue, and covered with a brown to black or violaceous ectostroma; cylindrical to pyriform asci in which the ascospores may be biseriately arranged posteriorly; and one-celled, dark brown spores possessing elongated germ slits. The classical separation between Poronia Willd. ex Fr. and Podosordaria is maintained. An emended generic description and key are provided. Four new species and one new combination are described and illustrated—P. crinita on cow dung from the United States; P. ianthina on burro and goat dung from Mexico; P. phoenicea on zebra dung from Kenya; P. vinacea on burro dung from Mexico; and P. violacea (Sordaria violacea Ell. et Ev.) on cow, sheep, horse, and rabbit dung from Canada and the United States. One additional new combination, P. hircina (Poronia hircine Tai et Wei), is proposed. Brief comparative descriptions are included for those species not treated in detail. Short descriptive notes are provided for several taxa considered as doubtful representatives.

The Third

Twenty-three species of trilobites are recognized in the lower Mississippian Caballero and Lake Valley Formations of southern New Mexico. Species exhibit a segregation into shelf and off-shelf faunas, and can be subdivided into three distinct stratigraphic faunas. Species found in the Caballero Formation are similar to those found in the Chouteau Formation of Missouri. A second fauna, comprising species found in the Alamogordo, Nunn, and Tierra Blanca Members of the Lake Valley Formation, is correlated with the Fern Glen and Burlington Formations of Missouri. The third fauna found in the Arcente and Dona Ana Members of the Lake Valley Formation is correlated with the Warsaw and Salem Formations of the United States midcontinent region.Named species from the Kinderhookian Caballero Formation include: Dixiphopyge armata (Vogdes, 1891), Comptonaspis swallowi (Shumard, 1855), Brachymetopus indianwellsensis new species, Ameropiltonia perplexa new species, Griffithidella caballeroensis new species, and Kollarcephalus granatai new genus and new species. Named species from the Lake Valley Formation include: Pudoproetus fernglenensis (Weller, 1909), Breviphillipsia semiteretis Hessler, 1963, Griffithidella doris (Hall 1860), Phillibole planucauda (Brezinski, 1998), Piltonia carlakertisae new species, Australosutura llanoensis Brezinski, 1998, Thigriffides triangulatus new species, Thigriffides? alamogordoensis new species, Namuropyge newmexicoensis new species, Nunnaspis stitti new genus and new species, Hesslerides arcentensis new genus and new species, as well as an unnamed species of Proetides Hessler, 1962, Namuropyge Brezinski, 1988, and Thigriffides Hessler, 1965.
