Some dinosaurs ate lizards, turtles,
eggs, or early mammals and some hunted other dinosaurs or scavenged lifeless
animals. Most, however, ate vegetation (but not grass, which hadn't evolve
yet). Rocks that contain dinosaur bones also contain remnant pollen and spores
that indicate hundreds to thousands of types of plants existed during the
Mesozoic Era. Many of these plants had ripe leaves, including evergreen
conifers (pine trees, redwoods, and their relatives), ferns, mosses, horsetail
rushes, cycads, ginkos, and in the latter part of the dinosaur age blossoming
(fruiting) plants. Although the precise time of origin for flowering plants is
still unsure, the last of the dinosaurs certainly had fruit available to eat.
