Under this name Ettingshausen described the tjrpe-specimen of the genus from Lower Lias strata at Steierdorf in Hungary. He assigned the plant to the Coniferae on the ground of a resemblance of the pinnules to the phylloclades of Phyllodadus. Thinnfeldia rhomboidalis bears a close resemblance to T. odon- topteroides, but the pinnules are usually longer and narrower, as shown in the English specimen from the Lower Lias of. Fig. 359.

The darker margin of the pinnules shown in fig. 3G0, C, gives the impression of a revolute lamina, but a microscopical examination points to a thicker cuticle at the edge of the segments. The species is recorded from Jurassic rocks of France, Ger- many, Italy, India, Australia, and elsewhere'. Palaeobotanical literature contains numerous records of ' For references, see Seward (04) p.
