Western Border

The deposits of the Devonian period over a large area in the interior of North America to the south of the great lakes are known to be wholly of marine type and to have continued those of the Silurian period. They were formed in a great gulf open to the south. Along the western border of this gulf shore-deposits and, during Upper Devonian times, deposits of Old Red Sandstone type were accumulated, while in the middle of the gulf the resulting rocks were limestones and shales. In Ohio, following on a narrow band of what is regarded as Oriskany Sandstone (Lower Devonian), the Corniferous limestone and some local representatives of the Hamilton formation represent the Middle Devonian. Above this comes a great mass of black shale, which here represents the whole Upper Devonian and may continue up into black shales of the Lower Carboniferous. A black shale at the base of the Upper Devonian rocks has an extensive range in the central region of North America, being represented by the Huron shale in Canada and the Genessee shale in New York. Drifted land plants from the coast of the gulf, or from islands in it, have been found in the black shale and also in the underlying Corniferous limestone, and some other fossils are commonly spoken of as Algæ but have afforded little or no botanical information.

Floodplain Sediments

During the Late Devonian, in what is now northcentral Pennsylvania, slow moving streams meandered across the plain of the "Catskill" Delta. A varied fish fauna lived in these streams, and their remains are entombed in the ancient stream channel and floodplain sediments. In the 1830's, English railroad engineer Richard Cowling Taylor visited the coal mining community of Blossburg and remarked on the analogy between the Old Red Sandstone of England and that found near Blossburg. Not long afterwards, James Hall (1811-1898), best known for his work on Paleozoic invertebrates of New York, also visited Blossburg to clear up vexing boundary problems in the New York formations. He obtained fish scales from the red sandstones, many of which he identified as scales of Holoptychus nobilissimus, a crossopterygian fish described by Louis Agassiz in 1839. In his annual report for 1839 to the New York Legislature, Hall also took note of some large scales, which were unlike any previously described. Under pressure from the Governor, Hall, like the other survey scientists, had to submit timely reports even if studies were incomplete, and he hurriedly described the new scales, referring them to a new genus and species, Sauritolepis taylori. In his final survey report (1843). Hall dealt more fully with the new fish, renaming it Sauripteris taylori based on the fin structure, the significance of which he had not earlier recognized. The Blossburg fishes did not languish in obscurity; James DeKay referred to them in his checklist of fishes of New York, as did Charles Lyell in his 1845 Travels in North America. In 1890 John Strong Newberry placed the fish fossils in the Lower Carboniferous; he also described several new species. Hall's handling of the fossil fish he had before him and, indeed, the reasons for entering Pennsylvania in the first place, are emblematic of the way much science was practiced in the first half of the 19th century. Further, recent field work in the Blossburg area shows Hall's astuteness as a field geologist for he correctly placed the fish in the Upper Devonian, although in this region the Upper Devonian-Lower Carboniferous boundary is not well defined.

Glass Working

The eighteenth-dynasty royal city of Malqata has been selected, since much evidence has been discovered here, particularly with regard to faience-production and glass-working, and there is also limited evidence of metalworking and sculpture-production. The settlement itself dates to the reign of Amenhotep III, and more specifically to his thirtieth regal year, when it was established to celebrate the king’s first ḥb-sd (Sed-) festival, the jubilee and rejuvenation celebration of his thirty years of reign. He celebrated a total of three festivals, the other two taking place in his thirty-fourth and thirty-eighth regal years. Due to the somewhat patchy nature of the early excavations and survey work done at Malqata, especially between 1888 and 1971, no genuine spatial analysis, such as was done for the material from Amarna or Gurob, has been possible for Malqata. The early excavation reports, for instance that by Tytus, or those by Winlock for the Metropolitan Museum missions, simply state in a matter-of-fact way that they located the remains of glass factories in, for example, the South Village. They usually continue to list some of the artefacts that were found, which would indicate the presence of glass-working and faience-manufacture in the area, but they do not describe these objects in any detail, and nor do they indicate where—within the large area covered by the South Village—they were found. However, the author has had the opportunity to study the unpublished archive material from the early excavations at Malqata by the Metropolitan Museum of Art, New York, which took place during the early years of the last century. The excavation diaries kept in these archives revealed no detailed information as to more precise locations or quantities of finds. They did, however, make possible a better understanding of the origins of these interpretations, and the sample of relevant artefacts examined made possible further identification and clarification of their nature. In addition, the author was able to access some of the objects relevant to glass-working and faience-production from Malqata at the Brooklyn Museum and was furthermore given permission to study some of the unpublished site reports, plans, and finds lists from the University Museum of Pennsylvania mission, which took place between 1971 and 1977.

The article deals with the lithology and geochemistry of organic matter of Upper Devonian-Lower Carboniferous deposits (Carbonate Devonian) of the eastern part of the South Tatar arch. Rocks of this age have a high generative potential due to increased concentrations of organic matter (OM) and its phytogenic and zoophytogenic composition. They refer to non-traditional sources of hydrocarbons. The generative potential depends on the facial environment and the transformation of OM. The highest potential have carbonate-siliceous and siliceous-carbonate rhythmites domannic horizon.

AbstractAn Ordovician–Silurian boundary section marked by an uninterrupted, relatively high rate of black shale sedimentation and abundant, diverse graptolites is described from the south-central Pyrenees. The structurally simple Estana section comprises the uppermost part of the quartzite-dominated Bar Formation and overlying black shales of late Hirnantian and early Rhuddanian age, which have been dated by graptolites to the upper Metabolograptus persculptus and lower–middle Akidograptus ascensus–Parakidograptus acuminatus biozones. Due to the absence of M. persculptus, a Metabolograptus parvulus Biozone correlative with the upper part of the persculptus Biozone is recognized below the lowest occurrence of akidograptids, which indicate the base of the Silurian System. The graptolite fauna comprise 27 species including Normalograptus minor, N. lubricus, N. rhizinus, Hirsutograptus, Korenograptus bifurcus, K. bicaudatus, K. lanpherei and Nd. shanchongensis, most of which were formerly considered to be endemic to the low-latitude palaeobiogeographical province of China, Siberia and northern North America. Two new species, N. baridaensis and N. ednae, are described. The succession of graptolite assemblages in the Estana section, and occurrence of several cosmopolitan taxa in its parvulus and lower ascensus–acuminatus biozones that are unknown elsewhere in peri-Gondwanan Europe, suggest that strata immediately surrounding the Ordovician–Silurian boundary may be absent, highly condensed or oxic and barren of graptolites in other sections of northwestern peri-Gondwana. Common graptolite synrhabdosomes and abnormal rhabdosomes may indicate some environmental stress in the parvulus Biozone, although the rather uniform black shale lithology, total organic carbon content and δ13Corg values suggest uninterrupted sedimentation under stable, anoxic conditions.

Age Determinations

Stratigraphic “displacements or dislocations” are coarse clasts and / or objects (such as unaltered remains or conodont-elements) slowly mobilizing or migrating vertically upward through a fine-grained matrix by a cryogenetic process known as “upfreezing” due to freezing temperatures. The process was originally established by periglaciologists and cold-climate geomorphologists who applied it only to unconsolidated, sedimentary deposits. In this study, the process is applied to the marine, pre-lithified, black shales of the Upper Devonian, Chattanooga Shale Formation, specifically in Tennessee, USA. The importance of this recognition is to alert paleontologists and stratigraphers about the strong possibility of inaccurate age-determinations made concerning coarse objects such as a conodont-element (denticles) (but not fossilized molds) because of their fossilized presence in age-determined, stratigraphic, rock levels when the apatite-composed denticles may have instead been initially deposited at a lower stratigraphic level during pre-lithification of the fine-grained, host-rock (shale) before the paleo-upfreezing process mobilized the denticles upwards. Many lines of evidences are given in this study towards apparent, predominant, freezing temperatures in the pre-existing, Chattanooga Sea of the Appalachian Basin, including particular, supposed, bioturbated, pre-lithified, organic black shale that is reinterpreted here as cryoturbated, pre-lithified, organic, black shale.

Terrestrial Invertebrate

The oldest recorded terrestrial invertebrates are various small Diplopods (millepedes) from the Lower Old Red Sandstone of Britain which were probably preserved preferentially due to their robust calcified exoskeleton. While the myriapod affinities and terrestrial habits of the earliest, pre-Prídolí, claims are highly questionable, true diplopods are known from the latest Silurian (Stonehaven Group) and Lower Devonian of Scotland. In addition, a variety of enigmatic myriapod-like arthropods occur sporadically in the late Silurian-Lower Devonian freshwater facies of the M idland Valley of Scotland and Welsh Borderlands. Among these, the kampecarids ss. constitute a discrete group of short-bodied, diplopodous uniramian arthropods, possibly with myriapod affinities and aquatic habits. In contrast to the diversity of chelicerate groups represented in the later terrestrial invertebrate faunas of Rhynie, Aiken and Gilboa, the Middle to Upper Devonian fossil record of the Myriapoda is very sparse. While true diplopods are notably absent, a variety of fragmentary chilopods (centipedes) are now known from the Gilboa Fauna (Givetian) of New York State.

Late Devonian (late Famennian) miospores have been found in the lowermost 7.3 m of the Horton Group on Harding Brook in the type area, Windsor Subbasin, Nova Scotia, below Tournaisian miospores of the Emphanisporites rotatus – Indotriradites explanatus Zone. Extending the age of the Horton Group in the type area down into the latest Devonian shows that the lowest beds of the ~ 1000 m thick group are coeval with latest Devonian rocks elsewhere in the Maritimes Basin that have been excluded from the Horton Group by some authors. Evidence presented here favours the argument that Late Devonian rocks lithologically similar to the Horton Group, deposited on the Acadian unconformity, should be included in that group. Miospore evidence indicates a minimum age of about 355 Ma for exhumation of the northeastern part of the South Mountain Batholith.

A sequence of Upper Devonian echinoderm debris beds with graded texture, interbedded with shale, overlies the Middle Devonian Ramparts Formation in the subsurface at McDermott Canada GCO South Maida Creek G-56 well on the south side of Mackenzie River near Carcajou Ridge.The interval of echinoderm debris can be divided into thick 2- to 7-ft (0.6- to 2.1-m) beds of graded skeletal remains lacking shale, and thinner intervals from 1 to 2 ft (0.3 to 0.6 m) thick of graded skeletal remains with interbedded black shale. The echinoderm beds, not present in the subsurface at nearby wells, are probably of local origin. Similar beds of echinoderm debris with graded texture, also of probable local origin, crop out at Powell Creek in the Mackenzie Mountain foothills.
