...Fig. 4 The lectotype of Neolagarograptus tenuis ( Portlock, 1843 ), BGS GSM 7800, from the Limehill stream section, Pomeroy, Ireland (left); and sketch of lectotype slab (right) with measurements of width and 2TRD of graptolites suggesting relative extension parallel to the lectotype...

... patterns of graptolite abundance and diversity. The most striking signature comprises several marked peaks in abundance of the distinctive taxon Neolagarograptus tenuis (Portlock) within this interval. Such ‘bloom events’, if recognized further afield, may provide very fine-scale stratigraphic resolution...

The base is defined by the appearance of Stimulograptus sedgwickii , which appears together with Neolagarograptus tenuis (Hutt, 1974 –1975).
