The Scottish Coal Measures Group is a lithostratigraphic unit referring to the coal-bearing succession of rock strata which occur in Scotland during the Westphalian regional stage of the Carboniferous Period.
Amphibians known from the group include embolomeres (Anthracosaurus, Palaeoherpeton, Pholiderpeton [formerly Eogyrinus]) and baphetids (Baphetes, Loxomma, Megalocephalus).
[2][3] Typical Westphalian-age marine fossils and plant impressions are abundant in some coal beds.
Insect fossils are rarer in Scottish coal relative to England or Wales.
Only five insect genera are known from the Scottish coal measures: Truemania (a dragonfly-like meganisopteran), Lithomantis and Idoptilus (palaeodictyopterans), and Archimylacris and Lithomylacris (roachoids).
