Abstract
Two malacostracan crustacean genera are described from the Langsettian (upper part of the Bashkirian, Lower Pennsylvanian) of the Scottish Coal Fields in the Midland Valley of Scotland. One is the youngest occurrence of
Tealliocaris
Peach, 1908 and was found at Polkemmet Colliery near Whitburn. It is recognised as a new species,
Tealliocaris elliotti
, based on the presence of eight spines on its scaphocerites and lateral convergent carinae of the telson. The other crustacean is a unique specimen from the Ardenrigg Colliery at Wester Bracco, North Lanarkshire in similar shales of Langsettian age. There are no distinguishing characters preserved that would identify it as a new species, but it can be placed in
Palaeocaris
Meek and Worthen, 1865 based on the well preserved features of the tail fan. This is the first record of this genus in Scotland, although specimens of
Minicaris brandi
Schram, 1979 from the Namurian (Serpukhovian, Upper Mississippian) shales of Bearsden are now here also considered to be a species of
Palaeocaris
.
期刊介绍：
Although published only since 1965, the Scottish Journal of Geology has a long pedigree. It is the joint publication of the Geological Society of Glasgow and the Edinburgh Geological Society, which prior to 1965 published separate Transactions: from 1860 in the case of Glasgow and 1863 for Edinburgh.
Traditionally, the Journal has acted as the focus for papers on all aspects of Scottish geology and its contiguous areas, including the surrounding seas. The publication policy has always been outward looking, with the Editors encouraging review papers and papers on broader aspects of the Earth sciences that cannot be discussed solely in terms of Scottish geology.
The diverse geology of Scotland continues to provide an important natural laboratory for the study of earth sciences; many seminal studies in geology have been carried out on Scottish rocks, and over the years the results of much of this work had been published in the Journal and its predecessors.
The Journal fully deserves its high reputation worldwide and intends to maintain its status in the front rank of publications in the Earth sciences.
