extinct animals by a.a and r.d



                           -Extinct Animals-

  1.  Palaeozoic Era


  • Dimetrodon
The Dimetrodon lived in the late Permian period. Their fossils were found in Northern America. Texas and Oklahoma to be exact. Recently, they have found Dimetrodon fossils in Germany.  They are mostly known for their big sail on the back of their bodies. It is formed by elongated spikes extending from the vertabrae. It walked on all fours and had a medium sized tail. It had a curved skull. It has been mistaken for a dinosaur even though it went extinct 40 million years before the dinosaurs. It has been assigned to the group, mammalian synapsids, or, mammalian reptiles.

2. Mesozoic Era

  • Pliosaur
Pliosaurs, or Pliosauroidea, are a now extinct reptile that lived in the Jurassic period. Their fossils are found in, Africa, Australia, China, Europe, North America, and South America. They have a 'short' neck and a    elongated head, with larger hind flippers than fore flippers. They were carnivorous and their long and their strong jaws carried many sharp teeth. They were believed to eat fish, sharks, ichthyosaurus, dinosaurs and other plesiosaurs. 

The Pliosaur became extinct at the end of the Cretaceous period, about 65 million years ago. It became extinct because of the mass extinction event.

  3. Cenozoic Era

  • Tasmanian Tiger 
The Thylacine, or as it is most known as, the Tasmanian Tiger is one of the largest known carnivorous marsupials. They lived in the Cenozoic era and were native to Tasmania. The Thylacine was relatively shy and nocturnal. It had the appearance of a medium sized dog  except it had a stiff tail and had a pouch like kangaroos. It got its name from it's black stripes running down its back. Both of its genders have pouches and these serve as an external sheath for protecting their external reproductive organs. 

It went extinct because of over hunting encouraged by bounties though there were other contributing factors like, disease, the introduction of dogs, and humans. It went extinct by 1936. There were efforts of preservation but the last Thylacine died at the Hobart zoo in 1936.

Otzi was excavated in Tisenjoch pass, he got this name because his body was mummified it was found near a glacier near the border of Italy and Austria. otzi is the world's oldest wet mummy, and the clothes he wore and equipment he carried are unique.

2. Saber Tooth Cat

  A saber-toothed cat  is any member of various living and extinct groups of predatory mammals that are characterized by long, curved saber-shaped canine teeth which protruded from the mouth even when closed. The saber-toothed cats, both living and extinct, have been found almost worldwide from the Eocene era to the end of the Pleistocene era 42 million years ago  – 11,000 years ago .
The first saber-toothed cat fossil in Canada was found in Medicine Hat, Alberta.The large cat was unearthed in 2003 by Eric Scott.

Taiga ecosystems

Image
Location of the Taiga Ecosystems The  taiga  is the largest biome. The  taiga  is primarily a coniferous forest (evergreen trees with needles) like the temperate rainforest, but the  taiga  is  located between 50 degrees latitude north and the Arctic circle. The  taiga  is a forest of the cold, subarctic region. The subarctic is an area of the Northern Hemisphere that lies just south of the Arctic Circle. The  taiga  lies between the tundra to the north and temperate forests to the south. Alaska, Canada, Scandinavia, and Siberia have Taiga. Climate The  taiga  is the terrestrial biome with the lowest annual average temperatures after the tundra and permanent ice caps. ... The  taiga  or boreal forest has a subarctic  climate  with very large temperature range between seasons, but the long and cold winter is the dominant feature. Plants There are some lichens and mosses, but most  plants ...

littoral zone ecosystem

Image
Littoral Zone Location The littoral zone or nearshore is the part of a sea, lake, or river that is close to the shore. In coastal environments, the littoral zone extends from the high water mark, which is rarely inundated, to shoreline areas that are permanently submerged.                                      Climate of littoral zones The air and water  temperature  can range from extremely hot to below freezing to moderate. The average range of air  temperature  is from 75°f to 102°f. The  intertidal zone  does have seasons. The inter tidal  zone  has hot and humid summers, moderate springs and falls, and cool harsh  winters.                                                         ...
