A new species of Anillinus Casey, 1918, is described from the Oak Ridge area, Roane County, Tennessee, in the eastern United States. Based on the presence of two patches with effaced microsculpture on the vertex, Anillinus inexpectatus, new species, belongs to the Anillinus loweae-group of species. Within this group, a patch of long setae on the ventral margin of the median lobe of the aedeagus places the new species close to Anillinus steevesi Barr, 1996. Modifications to a previous key for the A. loweae-group species are provided for identification of the new species, and zoogeographical considerations and biogeographical barriers for the A. loweae-group species are discussed.

Two new species of crane flies in the genus Tipula Linnaeus, 1758, subgenus Emodotipula Alexander, 1966 (Diptera: Tipulidae: Tipulinae), are described from Taiwan and Thailand. Tipula (Emodotipula) lishanensis, new species, is the first representative of the subgenus known from Taiwan and is closely related to Tipula (Emodotipula) thailandica, new species, here described as the first species of that subgenus from Thailand based on characters of external male genitalia and on DNA-sequence comparisons. Illustrations of the diagnostic morphological features of the new species are provided.

In an effort to understand how and if Cu isotopes can be used to trace native copper artifacts to their mineral deposits of origin, this study presents Cu isotope measurements from weathered native Cu artifacts and ores known to be derived from the Precambrian native copper deposits of Michigan. The five weathered artifacts have Cu isotope compositions ranging from δ⁶⁵Cu= 0.54 to -1.15%o. Weathered glacial till native copper nuggets range from δ⁶⁵Cu= -0.12 to 0.54%o, non-weathered ores have δ⁶⁵Cu= 0.33 ± 0.2%o (n= 42 from the literature and this study), a completely oxidized copper rind derived of large glacial boulder of native copper has -0.04%o. The oxidized rinds along with the weathered artifacts possess isotopically lighter signatures in comparison to the non-weathered ores and interiors of weathered copper nuggets.

The copper isotope data indicate the interiors of oxidized nuggets correlate with the non-weathered ores. Copper from the artifacts was sampled as micro drill bits (0.001–0.0009g) and larger cut pieces of the artifacts (>0.5g). Only the larger sample artifacts have the same copper isotope composition as the non-weathered ores, and not the oxidized rinds, and non-weathered interiors of copper nuggets. Therefore, when considering the unreacted interior of the native copper artifacts, the copper isotopic composition matches that of the known copper ore source. In contrast, weathering clearly depletes ⁶⁵Cu on the surfaces of artifacts and micro-sampling of the outer rims does not yield similar isotope results between sources and artifacts.

Acanthospondylus pennsylvanicus, new genus and species, is described and illustrated on the basis of a single specimen from the Conemaugh Group (Late Pennsylvanian) of western Pennsylvania. Distribution and morphology of ossicles similar to those of Eospondylus primigenius Stürtz, 1886, from the Early Devonian of Germany, including the absence of radial shields, dorsal and ventral arm plates, and the relatively wide separation of laterals over the ambulacral groove, indicates that Acanthospondylus belongs to the family Eospondylidae (Oegophiurida, Zeugophiurina) along with Eospondylus Gregory, 1897, and Kentrospondylus Lehmann, 1957. This extends the range of Eospondylidae from Early Devonian (Siegenian and Emsian) to Late Pennsylvanian (Early Kasimovian [Missourian]).

Forty-six species, assignable to 36 brachiopod genera, are recognized, described, and illustrated from the Lower Mississippian Redwall Limestone of northern Arizona. Seven new species are recognized, four of which are named. Named species are: Spinocarinifera (Seminucella) costatula, new species; Magnumbonella ampla, new species; Setigerites gutschicki, new species; and Spirifer redwallensis, new species. The remaining three newly recognized species remain in open nomenclature because study material was too poorly preserved to justify naming. The majority of brachiopod species studied were recovered from the Thunder Springs and Mooney Falls members near the middle of the formation. The basal Whitmore Wash Member and uppermost Horseshoe Mesa Member contain only sparse and poorly preserved brachiopod material. The spotty stratigraphic distribution of collections, which were recovered from largely geographically disparate locations, resulted in the creation of a stratigraphic range chart that exhibits no recognizable segregation into any potential brachiopod zones.

Many of the Redwall Limestone's brachiopod species are known from contemporaneous formations elsewhere in the Cordillera or central United States. Biostratigraphically key species such as Marginatia fernglenensis (Weller, 1909), Marginatia burlingtonensis (Hall, 1858), Stegacanthia bowsheri Muir-Wood and Cooper, 1960, Fernglenia vernonensis (Swallow, 1860), Voiseyella novamexicana (Miller, 1881), and Punctospirifer subtexta (White, 1862), indicate that much of the Thunder Springs and Mooney Falls members is correlative with latest Kinderhookian (late Tournaisian) through latest Osagean (early Viséan) formations of the American Midcontinent. These correlations indicate that the Redwall Limestone is temporally equivalent to the Fern Glen-Burlington formations of the central United States. These correlations are consistent with other Redwall forms that are biostratigraphially useful, such as foraminifers.

Diplodocus carnegii Hatcher, 1901, is a sauropod dinosaur that was originally recovered in the late 19^th century in the Upper Jurassic of North America. The large amount of bones recovered permitted the reconstruction of the original skeleton at the Carnegie Museum in Pittsburgh, Pennsylvania, United States of America. A series of casts of the specimen were made and donated by Andrew Carnegie to different countries in Europe and Latin America. The cast of D. carnegii mounted in 1912 at the Museo de La Plata was one of the nine replicas donated by Carnegie. The history of the discovery, the trip to Argentina by Carnegie Museum personnel, and the mounting of the cast skeleton are related in this contribution.
