1. Nowadays botanists divide the cycad-like plants into two major groups which may not be particularly closely related: the Cycadales, which include the living species, and the Bennettitales, an important Mesozoic group of plants which have smaller fructifications scattered among the bases of the leaves.
2. In the forests of the Mesozoic there were large numbers of trees and shrubby plants that looked at first glance like palm trees, with leafless stems crowned with bouquets of stiff, large leaves, deeply divided into long, unbranched leaflets.
3. Serpulid worm tubes are found in many different sediment types in rocks of Mesozoic and Tertiary age.
4. Their remains are commoner from the Mesozoic onwards, and at some levels, as in the Cretaceous chalk, they can be found in considerable numbers.
5. In the Mesozoic there was another great radiation of the crinoids, the typical forms having flexible arms, and it is crinoids of this kind that survive today.
6. The Outer Hebrides are composed primarily of metamorphic gneisses and igneous rocks of Precambrian age, apart from a small area near the town of Stornoway in Lewis, which has rocks of either upper Palaeozoic or lower Mesozoic age resting unconformably on the Precambrian rocks.
7. Left Varied shapes of leaves of fossil ginkgos, typically Mesozoic, with photograph of fossil example, natural size ( below ).
8. Nonetheless unlike many of their Palaeozoic companions, they survived the late Permian extinction, and the ancestors of the living Nautilus even underwent a minor evolutionary burst in the Mesozoic, where forms quite similar to the pearly Nautilus can be common fossils.
9. Corals looking superficially very like the rugose ones are found in Mesozoic and younger rocks, and are important on reefs today ( scleractinian corals).
10. Isolated, bladed shark's teeth are really rather frequent finds in Mesozoic and Tertiary rocks, often in the absence of any other fish remains.
11. Although they are commonest in rocks of the Late Palaeozoic, some Mesozoic plants have been regarded as a later branch of the seed ferns.
12. The earlier ammonoids had gently wavy sutures, and many of the Mesozoic ones had sutures almost incredibly folded and contorted, so it looks as if natural selection were generally favouring increase in the elaboration of the folds.
13. But during the Palaeozoic and Mesozoic they occurred in such profusion in inshore sediments that they are frequently important components of the rocks in which they are found.
