Evolution of man
|
Spread of mammals, birds
and pollinating insects
|
Dinosaurs dominate but become extinct at the end of this period; breakup
of Pangaea advanced; severe climate changes
|
Continents drifting;
climate hot and dry; flowering plants; cone bearing trees; minor mass extinction
- more than 80% of marine species died out
|
First true mammals;
many amphibians;
corals and seed plants; Pangaea forms;
bony fish; abundant insects
|
Reptiles dominate amphibians; diverse
species; mass extinction
at end - 90-96% of species die out
|
First reptiles; conifers and other trees; coal deposits;
primitive insects;
amphibians dominate land
|
First amphibians; snails; first bony
fish and sharks; tetrapods appear; mass
extinction at end which kills most fish
|
First jawed fish; first land plants; no seed bearing plants; insects appear
|
First fish and abundance
of invertebrates; trilobites, corals
and molluscs; first mass extinction in
prehistory
|
No life on land; marine

|
First multicellular life forms
