About 5 million years ago...
... somewhere in the universe...
... small fragments were clustering...
... and becoming bigger...
... and bigger!
To form one single huge rock.
A CHAOS!
And the Earth has form.
Pre-cambrian (4.600.000.000 years ago)
First rock formations.
70% of the current continents appears.
Formation of coacervates.
First prokaryotic cells.
First eukaryotic cells.
Formation of stromatolites.
First algae and fungus appears.
Thus, liquen formation.
The Sponge phylum appears.
The Cnidaria phylum appears.
The Plathelminthes, Aschelminthes and Nematoda phylum appears.
The Annelida phylum appears.
The Arthropoda phylum appears.
The Echinodermata phylum appears.
First Urochordate evidence.
Paleozoic (530.000.000 years ago)
1st mass extinction
The high decreasing of sea water level eliminated shallow water species.
The shells appears.
The Trilobites diversify.
The Chordates appears.
2nd mass extinction.
One huge glaciation killed many species of marine invertebrates.
The first Agnatha appears.
The Ostracodermi appears.
The mollusks diversify.
Vascular plants evidences.
Vascular plants appears.
First Gnathostomata appears.
The Coral form.
The marine scorpions dominates.
3rd mass extinction
Heating followed by quickly glaciation...
... reduced drastically the sea oxygen causing the extinction of many fish species.
Formation of mountains in North America an Europe.
The bryophyta and pteridophyta forest form.
The ostracodermi extinction.
Insects: the first animals to fly.
The acanthostega appears and with him, the fist body members.
And the ichthyostega, intermediate between fishes and amphibians.
The amniotic egg born.
4th mass extinction.
High volcanism in Siberia increased the Earh temperature by 18°F (10°C).
95% of the living species extinguished.
Formation of one single continent: the pangeia.
The reptile ancestor appears.
The first mammal-like reptiles appears.
Mesozoic (250.000.000 yeas ago)
The arcossauria diversify.
The first true mammal appears.
Ichthyosaurus: the first marine reptile.
The first dinosaur appears.
The proganochelys appears.
The pterossaurus became evident in this period.
First gymnosperm appears.
Apatosaurus: one of the biggest dinosaurs ever lived.
Seismosaurus: another huge herbivore of this period.
The first bird: archaeopteryx
The Nessie appears, a plesiosaurus.
The sharks appears in this period.
The rays appears in this period too.
The first plants with flowers: the angiosperms.
T-rex: the #1 predator!
Anhanguera psicator dominates the sky.
K-T extinction (Cretaceous - Tertiary)
1st theory: one meteor hit the Earth and extinguished the dinosaurs.
2nd theory: intense volcanism activities extinguished the dinosaurs slowly.
Cenozoic (65.000.000 years ago)
Ancestral opossum, just like the current ones.
Planetetherium: probably the ancestor of the dermopteras (colugo).
Plesiadapis: probably a primate ancestor.
Ambulocetus: this reptilian-mammal was one of the first to get back to the water.
Propalaeotherium: possible the horse ancestor.
Andrewsarchus: feared predator of this period.
Formicium giganteum: huge and carnivore, lived in this period.
Moeritheirum: possible the elephants ancestor.
Chalicothere: one of the strangest of this period had legs with very different lengths.
Smilodon: great cybertooth predator.
Indrocothere: the hugest terrestrial mammal ever lived could have 15 tons.
Phorusrhacus: great terrestrial carnivore bird.
Kentriodon: very alike the current dolphins.
Daphoenodon: one canine-ursine of this period.
Epigaulus: peculiar rodent had horns.
Australopithecus: the first primates to walk erect.
Dinofelis: terrible cybertooth cat possible predated primates.
Ardipithecus: possible the hominids ancestor.
Panthera leo spelaea: very alike the current lions, disappeared only 10 thousand years ago.
The mammoths were the largest Europe herbivores.
Coelodonta antiquitatis: those rhinos could weight 2.5 tons.
Neanderthals: they where good hunters but didn't adapt to climate changes.
