Armoured fish (Phylogenetic tree) - Animals in the Habitats and the Fossil sites, and Biodiversity

Classified animal picture guide. Clicking the Organism name shows the images, and pointing the Organism name shows the tooltip with three links at the left-top corner.
The followings are extinct armoured fishes excavated. The explanation in brackets is the ages they lived in extinct species, and the habitat in extant species. Note that Mya is million years ago. For example, "48.6～40.4 Mya" shows a range between 48.6 and 40.4 million years ago. The time range is shown in the Geological Time Table. The followings are a part of the Evolutionary Tree.
