Carboniferous and Permian Leaioidea (Branchiopoda: Conchostraca) from Australia: taxonomic revision and biostratigraphic implications

A review of the Carboniferous and Permian trilobites of Australia.

The first complete review of the Carboniferous and Permian trilobite species found within Australia is presented to assess the current standing of Australian taxa in a modern systematic context. The review consists of four families, 20 genera and 61 known species from the early Tournaisian to Moscovian (358.9 Ma to 304 Ma), throughout New South Wales, Tasmania, Western Australia and Queensland....

Plant Biodiversity Partitioning in the Late Carboniferous and Early Permian and Its Implications for Ecosystem Assembly

Timing of recovery from the end-Permian extinction: Geochronologic and biostratigraphic constraints from south China

Four volcanic-ash beds bracket the Early-Middle Triassic boundary, as defined by conodont biostratigraphy, in a stratigraphic section in south China. High-precision U-Pb dates of single zircons allow us to place the Early to Middle Triassic (Olenekian-Anisian) boundary at 247.2 Ma. Magnetic-reversal stratigraphy allows global correlation. The new dates constrain the Early Triassic interval char...

self-revision and third party revision in translation

اهمیت این پژوهش در آن بود که به گفت? بسیاری از پژوهشگرانِ حوز? بازبینی ترجمه، ادبیات موجود در این زمینه به لحاظ نظری و عملی چندان قوی نیست و بخش های موجود نیز برداشت مناسبی از این مرحل? فرایند ترجمه ندارند، اگرچه اخیراً توجه به آن به صورت نظام مند افزایش یافته است. در عین حال، پژوهش های موجود از یک سو بر دگربازبینی بیشتر از خودبازبینی تأکید دارند و از دیگر سو تنها به لحاظ نظری به این موضوع می پرد...
