The known stratigraphic ranges of 66 acritarch species from eight independently dated Middle Devonian sections in North America are plotted.

Twenty seven species are restricted to the Middle Devonian in North America, yet only 12 species occur in more than one section. None of these 12 species is, as yet, known to occur outside North by:   In summary, even though the Early Devonian paleolatitudinal reconstructions remain highly con- troversial, the level of endemism among acritarchs at generic and specific levels permits the recogni- tion of at least two distinct acritarch biogeographic units: the eastern North America (E.N.A.) subunit, and the Gondwanan unit divided into the Cited by: Upper Devonian and Carboniferous acritarchs have also been described from many other areas in North and South America, Africa, Europe, Asia and Australia, but the data are mainly based on spot.

The published record of Late Devonian acritarchs and prasinophytes now constitutes a reasonably comprehensive coverage for many parts of the world (Le Hérissé et al., ; Molyneux et al., Biostratigraphic distribution of the Appohimchi brachiopod fauna indicates continuous Early Devonian shelf deposition along the entire southern margin of Laurentia.

The largely emergent southwest-trending Transcontinental arch apparently formed a barrier preventing migration and mixing of many genera and species of brachiopods from the southern.

In Gao and Liu's () one page paper, 10 genera are listed, but only one species is named and that is the long-ranging Veryhachium trispinosum. Middle Devonian microphytoplankton assemblages are better known than, for example, Early Devonian ones, however the stratigraphic and geographic distribution of well-described assemblages is still uneven (Le Hérissé et al.,Molyneux et al.,Wicander and Playford, a).

Many are clustered in particular areas, particularly North. -Le Hérissé, A.,Paleoecology, biostratigraphy and biogeography of late Silurian to early Devonian acritarchs and prasinophycean phycomata in well A, Western Libya, North Africa: Review of Palaeobotany and Palynology, v.p.

Devonian bactritids are described for the first time from South America. They come from siliciclastic rocks of the Talacasto Formation in the Precordillera Basin, west-central Argentina. The host strata span the Lochkovian—Emsian and contain other non-ammonoid cephalopods as well, thus refuting the alleged virtual absence of cephalopods in circumpolar Devonian basins from southwestern.

The present publication is the first unit to be issued of a bibliographic index which is intended to fill the gap between Weller’s Bibliographic index of North American Carboniferous invertebrates and Bassler’s Bibliographic index of American Ordovician and Silurian fossils.

Other units, of which there will be nine, are to be published in the order in which they are completed. 1. Introduction. Although palynological studies of the subsurface mid-Paleozoic succession of Libya were carried out by the early s (e.g.

Wray, ), and the stratigraphic utility of acritarchs has long been appreciated, many data have been kept confidential and only a few papers have been published (e.g. Richardson and Ioannides,Buret and Moreau-Benoit,Moreau. An illustration of an open book.

The Devonian (/ d ɪ ˈ v oʊ. n i. ən, d ə- d ɛ-/ dih-VOH-nee-ən, də- deh-) is a geologic period and system of the Paleozoic, spanning 60 million years from the end of the Silurian, million years ago (Mya), to the beginning of the Carboniferous, Mya.

Introduction During the systematic lithostratigraphic description of the Palaeozoic deposits from the subsurface of the Campine Basin in northern Belgium (Lagrou, ), it appeared that certain stratigraphic intervals in deep boreholes, already identified and investigated as separated units by different authors (Langenaeker, ; Laenen, ), were not yet formally named.
