* In the Q mankind caps the prominent insect, mammal, fish, bird and angiosperm plants, presences, which meet the Cretaceous that, with the J, T, and P down into the Carboniferous. abounds in reptiles (dinosaurs), fish both bony and shark-like, brachiopods and ammonites, with conifers abundant. Then we move into ages rich in amphibians, shark-like fish, insects, tetracorals, and productids.
The Ordovician and Cambrian favour nautiloids, graptolites, trilobites, and lingulella, while the Precambrian reveals bacteria and algae.
