Abstract
New high-resolution δ13Ccarb isotope data are presented through the lower part of the early Sheinwoodian carbon isotope excursion from a section in Buttington Quarry, Wales. The graptolite biostratigraphy of the section is established, with the base of the measured section within the Cyrtograptus murchisoni Biozone. The first appearance datums of the biozonal indices Monograptus firmus and Monograptus riccartonensis are recorded. The new isotope curve will provide the basis for future studies, particularly on the palynology of the section.
