Fig. 25. Serrate leaf morphology as evidence of plant–insect interaction falling under climatic control, anticipated
in a Palaeozoic gigantopterid Gigantonoclea from the latest Permian of South China (c), and further
developed in the early angiosperms, starting with marginal glands, as in the platanoid leaves from the
Cenomanian of Kazakhstan (d, e), and elaborating over an irregular double crenulation, as in Nammourophyllum
from the Cenomanian of Lebanon (a) or Trochodendroides from the Senonian of Sakhalin (g), to a regular
one in the younger broadleaves, e.g. Corylites from the Early Palaeocene of Sakhalin (b), and to emarginate
types in Ushia from the Late Palaeocene of Cisuralia (f) or Tiliaephyllum from the Early Palaeocene of
Tsagajan (h). After Krassilov (1976a, 1979), Krassilov & Shilin (1996), Krassilov et al. (1996a), Krassilov &
Baccia (2000).
