Which plants were not common in the mesozoic ara?

During the Mesozoic Era, flowering plants (angiOSperms) were not yet common, as they emerged later in the era, around the Late Cretaceous. Additionally, many modern plant families, such as those found in tropical rainforests, were also absent or not fully developed during this time. Instead, the Mesozoic landscape was dominated by ferns, cycads, ginkgoes, and conifers.
