Fig. 4 in Xenoxylon synecology and palaeoclimatic implications for the Mesozoic of Eurasia

Fig. 4. Generic diversity of Xenoxylon wood-assemblages during the Mesozoic times—global curve and curve for specific geographic areas. Note that the real diversity was probably much lower, because of taxonomical bias. Abbreviations: LT, Late Triassic; EMJ, Early to Middle Jurassic; LJEK, Late Jurassic to Early Cretaceous; LK, Late Cretaceous.
