This specimen may be provisionally referred to the genus Braehyphyllum; it agrees closely in habit with Thuites expansus, but the leaves are apparently spiral in their arrangement. This and other similar examples are too small and imperfect to assign with confidence to a distinct species, but they may be identical with the Yorkshire Inferior Oolite type, Brachyphyllum mamillare, Brongn. It is by no means easy, in many cases, to decide between Brachyphyllum and Thuites as the most fitting generic designation for coniferous twigs, and possibly some of the fossils referred to Thuites expansus are fragments of a Brachyphyllum.
