Timeline Of Dinosaurs From Now to Then
Clue- Pssssst this will help you in the quizzes. there are 17 different dinosaur periods check it out.
Quaternary
Present Day - 5
Many mammals vanish during a vast ice age. Modern humans emerge and spread world wide. Species of plants and animals are similar to what we see today.
Tertiary
5 - 145
The continents have moved to positions near where they are today.
Flowering plants thrive and diversify. Vast forests exist in the tropical and temperate environments. Mammals spread and diversify.
Mesozoic Era
Age of Medieval Life
(Time of the Ruling Reptiles)
Cretaceous
145 - 200
North and South America begin to split apart. India is a separate continent, In the north are Euramerica and Asiamerica, with differing plant and animal species.
Dinosaurs diversify and rule until the end of the Cretaceous period when they die out in a mass extinction along with many other marine and terrestrial species. Flowering plants appear, and insects begin to pollinate.
Jurassic
200- 250
The supercontinent, Pangea, splits and the Atlantic Ocean appears separating Asia from the Americas and Africa.
The age of the Ruling Reptiles is in full swing. Dinosaurs rule the earth and pterosaurs rule the skies. Dinosaurs are much larger and include giant herbivores. The first birds appear.
Triassic
250 - 295
The first dinosaurs and mammals appear; they tend to be small and quick predators who run on their back legs. Cycads abound, seed ferns go extinct. Ammonites are common. Dinosaurs, crocodiles and pterosaurs emerge and diversify.
Paleozoic Era
Age of Ancient Life
Permian
295 - 362
All land is in one giant continent, Pangea. Ferns, seed ferns and conifers abound. Insects diversify and spread. Many marine animals, including the trilobites, go extinct.
Carboniferous
362 - 418
All land is in two great continents, in the north is Euramerica and Gondwanaland is in the south.
The first reptiles appear on land, as do the first conifers and cycads. Giant ferns, horsetails, and club mosses are common. Trilobites become less common, graptolites go extinct.
Devonian
418 - 439
Amphibians and insects begin to invade the land. The earliest ferns and plants with seeds appear. Fish abound.
Silurian
439 - 490
The first life emerges on land, as plants and invertebrates. Fish develop and split into the bony fishes (teleosts) and the cartilaginous fishes (sharks and rays). Marine invertebrates continue to thrive.
Ordovician
490 - 543
Corals, bryozoa and graptolites thrive along with the marine life of the Cambrian. The first true vertebrate fish discovered.
Cambrian
543 - 2500
Marine life abounds, including red and green algae, brachiopods, gastropods, trilobites, sponges. The earliest fishes appear.
Precambrian Era
(Time before Life)
2500 – 4600
Time from the birth of the planet approximately 4.6 billion years ago, until the first simple life forms appeared about 3.6 bya, including early bacteria and blue-green algae.
The first multicellular animals, such as worms and jellyfish, appeared near the end of this era.
