What dinosaurs had their food?


Dinosuars

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.
