Abstract Sphenothallus and fossils similar to Sphenothallus are found in Ordovician, Devonian, and Mississippian rock units in Ohio and adjacent states and provinces. Although the Ordovician of Québec, Ontario, and Indiana has yielded parts of tubes, Ordovician specimens from southwest Ohio and nearby areas consist almost entirely of holdfasts on hardgrounds and shelly fossils. Sphenothallus is abundant in the Chagrin Shale (Famennian) of northeast Ohio where it is found in about four percent of concretions that contain identifiable fossils. The Chagrin specimens, usually parts of tubes, are occasionally preserved three-dimensionally. The rate of distal expansion of Chagrin Sphenothallus tubes varies intraspecifically; thus, this rate cannot be used to distinguish species. Some Chagrin specimens are attached to larger, conspecific specimens and to articulate brachiopods. Brachiopods have also been found attached to Chagrin Sphenothallus. Bedford-Berea sequence (Famennian) specimens from northern Kentucky and Meadville Member (Kinderhookian or Osagian) specimens from the Cuyahoga Formation of northeast Ohio are usually preserved as flattened tubes. In both occurrences tubes are similar in width, indicating that individuals in each assemblage are probably the same age. Meadville tubes possess characteristics diagnostic of Sphenothallus, but Bedford-Berea specimens, which lack longitudinal thickenings and exhibit little tube tapering, cannot be assigned to Sphenothallus sensu strictu. Sphenothallus was a gregarious, opportunistic species, tolerant of dysaerobic conditions and able to colonize environments ranging from hardgrounds to soft, muddy sea bottoms. No distinct branching was observed among the Chagrin, Bedford-Berea, or Meadville specimens, suggesting that larval dispersal was the primary mode of reproduction for the genus.

Spinous oniscomorph millipedes are rare faunal components of the upper Palaeozoic (Shear, 1997). Amynilyspes (type species A. wortheni Scudder, 1882; OD) is an Upper Carboniferous spinous oniscomorph (pill millipede) which was first described from the Middle Pennsylvanian (Westphalian D equivalent) Fossil-Lagerstatte of Mazon Creek. Later Fritsch (1899) described two species ( A. typicus and A. crescens ) from the Wesphalian D Gaskohle of Nýřany in Bohemia. More recently A. typicus was recorded from the Stephanian B of the Saarland (Forster, 1973), then from the Stephanian B of the Blanzy-Montceau-les-Mines Basin (Langiaux and Sotty, 1977; Poplin, 1994). Although myriapods were already known to occur in the Montceau-les-Mines Lagerstatte (Langiaux and Sotty, 1976; Rolfe et al., 1982; Poplin and Heyler, 1994) the presence of Amynilyspes at Montceau-les-Mines was first published in a regional publication (“La Physiophile” Langiaux and Sotty, 1976, 1977), and it has passed almost unnoticed. Representatives of the genus Amynilyspes are a minor faunal component of Upper Carboniferous faunal assemblages. Hannibal and Feldmann (1981) published a revision of the oniscomorph millipedes from the Carboniferous of North America, including the type specimen of Amynilyspes wortheni Scudder, 1882 and newly collected specimens. Specimens of the genus Amynilyspes subsequently have been illustrated and discussed in various works (Hannibal, 1984, 1997; Shear, 1997). At Mazon Creek Hannibal and Feldmann (1981) listed 10 specimens of A. wortheni , plus an undetermined number of specimens in private collections. The percentages of the whole millipede fauna (excluding arthropleurids) are 0.1 percent in the Braidwood (nonmarine, freshwater) biofacies and 0.014 percent in the Essex (marine) environment (Baird and Anderson, 1997). A survey of fossil millipedes in the collections of the Field Museum of Natural History by one of us (JTH) in 1997 showed that oniscomorphs (mainly Amynilyspes ) comprise about 11 percent (24 …

Abstract Pleurojulid millipedes, known since the turn of the last century to be relatively abundant in the Westphalian D (Carboniferous: Pennsylvanian) Gaskohl of Nýřany, Czech Republic, are here also identified as an important component of the Pennsylvanian (Westphalian D) Mazon Creek millipede fauna preserved in ironstone nodules. Pleurojulids reach lengths approaching 10 cm, have as many as 69 body segments, medium-sized heads, and large ocellaria with upwards of 40 ocelli. Pleurojulids have previously been interpreted as having either a juliform-like or a colobognathan-like trunk-ring architecture. In order to distinguish between these two hypotheses, almost all pleurojulid specimens in museum collections were surveyed to document the deformation pattern of exoskeletal elements to aid in reconstruction of the trunk-ring architecture. The Nýřany specimens are completely flattened while the Mazon Creek specimens retain a degree of three-dimensionality. In order to assess how trunk-ring architecture controls patterns of deformation, a variety of extant millipedes were experimentally compressed. The distribution of exoskeletal elements in pleurojulid fossils was most similar to that seen in compressed extant polyzoniid millipedes. Based on the available evidence, pleurojulid trunk-ring architecture is reconstructed as semicircular in cross section, consisting of arched diplotergites, free pleurites firmly articulated to the lateral margins of the tergites and held in a near horizontal position, and free sternites. Pleurojulida are hypothesized to be basal helminthomorph, the sister group to Colobognatha, though inclusion in Helminthomorpha is equivocal. The taxonomy of previously described pleurojulid millipedes from Nýřany is revised and newly recognized specimens from Mazon Creek specimens are described. Two genera are recognized within the new order Pleurojulida: Pleurojulus and Isojulus. Two species of Pleurojulus are recognized: P. biornatus and P. levis. Pleurojulus aculeatus and P. pinguis are synonymized with P. levis. Only one species of Isojulus, I. constans, is recognized with I. setipes, I. marginatus synonymized with it along with Pleurojulus longipes and P. falcifer.

In the past few years the Cleveland Museum of Natural History has received several inquiries as to our source of dolomite for use with S.S. White® industrial airbrasive units. We have been using inexpensive, “agricultural” dolomite with these units for several years. This source was “discovered” by testing of a wide variety of dolomite sources by Peter Kotulak, a former preparator at the Museum, under the direction of M.E.W. We are currently using OHSO® Pulverized Limestone, a kiln-dried dolomitic limestone recommended for agricultural, and lawn and garden, use. It is produced by the Ohio® Lime Co., of Woodville, Ohio. A 22.7 kg (50 pound) bag costs

2.25, and is available at building supply companies. The dolomite must be sieved and dried to prevent clogging of the units line and nozzle. We use a Ro-Tap® Testing Sieve Shaker to sieve the material, with #30 (595 micron), #60 (250 micron), and #100 (150 micron) U.S.A. standard testing sieves. An incandescent desk lamp can be placed over an open container of the sieved dolomite to keep it dry. Used powder may be re-sieved for reuse if desired.

Abstract. A new helminthomorph millipede, Sinosoma luopingense new genus new species, from the Triassic Luoping biota of China, has 39 body segments, metazonites with lateral swellings that bear a pair of posterolateral pits (?insertion pits for spine bases), and sternites that are unfused to the pleurotergites. This millipede shares a number of characters with nematophoran diplopods, but lacks the prominent dorsal suture characteristic of that order. Other “millipede” material from the biota is more problematic. Millipedes are a rare part of the Luoping biota, which is composed mainly of marine and near-shore organisms. Occurrences of fossil millipedes are exceedingly rare in Triassic rocks worldwide, comprising specimens from Europe, Asia, and Africa, and consisting of juliform millipedes and millipedes that are either nematophorans or forms very similar to nematophorans.

ABSTRACT French and North American cherts used for millstones during the late eighteenth century and nineteenth century in Ohio are generally similar in color, hardness, presence of cellular porosity, and other characters. Although basic differences in fossil content and geologic age have been known since the 1830s, and previous authors have noted the presence of fusulinids and other fossils in Ohio buhrstone, and charophytes as well as gastropods in millstone pieces found in New England but imported from France, little attention has been paid to the fossil content of chert millstones in the United States. We document examples of chert millstones in Ohio, distinguishing cherts (French buhr) imported from the Tertiary of France for use as millstones from local Pennsylvanian cherts (buhrstone) used for millstones. French buhr (known as meulière in France), from the Tertiary deposits of the Paris Basin, contains gyrogonites belonging to the Oligocene species Gyrogona medicaginula, charophyte thalli, and freshwater gastropods. The fossil content of the Ohio cherts, as observed in millstones, is diverse, including Pennsylvanian (late Carboniferous) marine fossils, notably fusulinids, pelmatozoans. and brachiopods. The concepts and examples described in this paper are broadly applicable outside of Ohio as millstones made of Ohio chert were exported outside of Ohio to other states, and French millstones have been distributed worldwide, so these concepts can be applied to study of millstones (as well as other chert objects), found outside of North America as well. This study also serves as another example of the usefulness of steinkerns and molds of gyrogonites in identification of charophyte species.
