Life on earth

Subdecks (2)

Enchinoderms = starfish like creatures
Arthropods = jointed metazoa
conodont = jawless fish like eels
End ordovician extinction - 85% of all species due to volcanic winter
Silurian period contained graptolites and corrals
Devonian = vascular plants, gymnosperms, roots and age of fish
Late devonian extinction = 75% of all marine species due to cooling because of continental collision
Carboniferous = swamp and coal forests, insect and tetrapod development
Permian = dry climate and age of reptiles, synapids with cooling fins and therapsids (upright legs)
Permian extinction = mother of all: 90%, volcanic activity and acid rain
Triassic = Iystrosaurus high dominance and tetrapod bounceback
Triassic extinction = 80% due to volcanic activity
Jurassic = age of dinosaurs, ornithischian (orni this chan bird hipped), sauristhischan (saris this chan, lizard hipped)
Cretaceous = bird and flower evolution with a warm climate
Cretaceous extinction = 75% of all species due to meteor, end of dinosaurs
Paleocene = age of mammals, mega fauna, monotremes, marsoupials, placentals
