Whether an ancient biome can be re-created by people or not. Introduction: The naturally occurring species of flora and fauna that occupy particular, specific area is called as a biome. A Russian scientist named Sergey Zimov believes that present day biome of Siberian tundra which is dominated by the growth of shrubs and mosses is an artificial and man created landscape. He explains that about 10,000 years ago these tundra were created when prehistoric people wiped out the poulation of major herbivore fauna like bison, mammoth and wolly rhinos.

Let’s see what you already know! For this activity, you are a palaeobiologist interested in reconstructing ancient ecosystems. You have searched the scientific literature and found 5 clues:1. The majority of the field site (~100 km2) is mostly covered with limestone. However, in one area younger mudstone rocks are preserved above the limestone.2. The limestone has many invertebrate fossils including starfish, sea urchins, and coral, but mostly has bivalve shells. 3. The limestone also has vertebrate fossils. Small shark teeth are sometimes found. A single elasmosaurid plesiosaur tooth was discovered. Amazingly, several coprolites (fossilised dung) have fish vertebrae found in them; one coprolite even has a feather inside!4. The mudstone is rich in tiny ‘microfossils’ that include:• Small mammalian teeth • Pollen from 29 different families of flowering plants: the most common families are Caesalpiniaceae (peacock flowers)5. The mudstone also has larger fossils, including:• Pelvic and…

29) The Cretaceous extinction. which was the most recent mass extinction, occurred about 65.5 million years ago. What is the leading hypothesis to explain the Cretaceous extenction? A) The Indian sub-continent collided with the Asian techtonic plate, giving rise to the Hymalayan mountains which altered the jet stream and caused the planet to enter an ice age B) An asteroid about 6 km in diameter collided with Earth, which vaporized the caribbean ocean, set fire to north and south America, and expelled enough dust into the atmosphere to block the sun enough to result in a winter like environment all across the globe for several years C) A new group of predators evolved that were significantly better at capturing prey, to the point that they drove many species (including other predators and eventually themselves) to extinction D) Massive amounts of volcanic activity released tons of CO2, enough to significantly increase the temperature of the planet 30) The Permian extinction, which…
