چکیده انگلیسی
A novel well-preserved woody branch, Turpanopitys taoshuyuanense gen. et sp. nov. was collected in the early Triassic terrestrial deposits in the Turpan Basin, Northwest China. The permineralized wood is characterized by a heterogeneous pith, endarch primary xylem and Protophyllocladoxylon-type secondary xylem. The pith consists of parenchyma cells and supporting diaphragms formed by brick-like sclerenchyma cells. The quantitative growth-ring analyses of T. taoshuyuanense indicate that the species was evergreen, the leaf longevity being comprised between 3 and 15Â years. T. taoshuyuanense might indicate a warm humid climate with short dry periods in the Turpan basin in the Early Triassic. The Protophyllocladoxylon-type woods were widely distributed in different climate zone in both southern and northern hemispheres during the Palaeozoic and Early Triassic. The growth rings of the woods with Protophyllocladoxylon-type secondary xylem are good indicator for the palaeoclimate. The new specimen indicates that a warm humid climate with irregularly distributed short dry periods in the Early Triassic Turpan basin.
