Which were small and minor parts of terrestrial life during the Jurassic period?

During the Jurassic period, small and minor parts of terrestrial life included various insects, such as beetles and dragonflies, which played crucial roles in pollination and ecosystem dynamics. Additionally, small mammals and reptiles, like early therapsids and small dinosaurs, began to diversify, occupying various ecological niches. Ferns, cycads, and ginkgoes dominated the plant life, providing habitats and food sources for these smaller organisms. Overall, while large dinosaurs captured much attention, these smaller life forms were essential for the functioning of Jurassic ecosystems.
