The world's longest graptolite?
Abstract
An incomplete specimen of Stimulograptus halli 1.45 m long is recorded from the Aberystwyth Grits Formation north of Clarach, western mid-Wales. This is the longest graptoloid graptolite known. Assuming a growth rate similar to that of modern Rhabdopleura it lived for at least 25 years. Copyright
