II, 1898-99, in whichthere is reference to all previous writers, and quotations from the valuable paper ofWanner. THE TRIASSIC PERIOD. 41 of the Carboniferous trees. The group figure (Fig. 338) embracescharacteristic forms from the Newark formation. A few plant fossilshave been recovered from New Mexico, Arizona, and California (Taylors-.

Conifers:a, Palissya sphenolepis Brong., a form closely allied to Walchia; b, Cheirolepismuensteri Schimp.; c, Brachyphyllum yorkense Font.; d, Schizolepis liaso-keu-perinus Braun.

Limited coal deposits were formed in Germany and Scandi-navia, from the latter of which 150 species of plants have been The Land Animals. All evidences point to complete continuity between the Permianand Triassic land animals. The vicissitudes of shifting aridity andother changeable conditions seem to have markedly affected bothperiods, but not to have put barriers between them; rather to havemade adaptation to the one a fitting preparation for continuedevolution in the other.
