Zamites is an extremely common type of leaf fossil found throughout the Mesozoic. Though the fronds resemble those of cycads, Zamites actually belonged to an extinct group of seed plants known as the Bennettitales. This group is famous for its flower-like reproductive structures, which have led some palaeobotanists to speculate about a possible evolutionary link to true flowering plants, though their exact relationships remain uncertain.

Kimuriella densifolia is a bennettite from the Upper Jurassic of Japan, known from exceptionally well-preserved fossils that include stems, Zamites-type leaves, and both male (Weltrichia) and female (Williamsonia) reproductive structures in organic connection. This rare whole-plant preservation provides a detailed glimpse into the structure of a Zamites-type plant. The fossils show a divaricate branching pattern, in which the stem splits geometrically into two branches at each node, with reproductive organs emerging from the center of these junctions.

Kimuriella appears to have grown in dense thickets along a Jurassic river delta. While this species occupied a humid, lowland habitat, many other Zamites-type plants are known from drier environments and show traits suggesting adaptation to semi-arid climates.
