3. Some types of dinosaurs ate only meat ("carnivores") • some ate only plants ("herbivores") • And some ate both plants and meats ("omnivores"). DINOSAURS DIETSometimes, when we are very lucky, we can learn about dinosaurs' diets and lifestyles directly from fossils. Scientists have sometimes found fossilized dinosaur bones, complete with fossilized stomach contents. We know for example that Baryonyx was a fish-eater, and that Coelophysisprobably engaged in cannibalism, because of the stomach contents that have been found. For example, the discovery of Triceratops which seems to have survived from a Tyrannosaurus rex attack, suggests that Tyrannosaurus rex must have been actively hunting the animal, rather than just scavenging NOW INVESTIGATE ABOUT THESE ONES:

4. OTHER ANIMALS IN THE DINOSAUR WORLDThere´s a huge variety of animals that have lived with the dinos. To classify the following animals into the groups below, write with your own words what´s each group: BIRDS FISH REPTILES INVERTEBRATE MAMMAL AMPHIBIANS

5. THINK OF 2 ANIMALS LIVING IN…: FARM GRASSLANDS Make the list of their names and write Wild or Domestic next to them, you can also write CBD, if they are wild but they can be domesticated. JUNGLE RIVER FOREST SEA

6. Choose one animal of each category (amphibians, birds, fish, mammals, invertebrates and reptiles) and complete: CLASSIFY THEM!:

7. WHAT HAPPENED?? Dinosaur ExtinctionDinosaurs inhabited the earth for over 165 million years, during the Mesozoic Era. Most dinosaur species lived and died out during this period, but at the end of the Cretaceous period (65 million years ago), all remaining types of dinosaurs (with the exception of birds which had already evolved, and are widely believed to be descended from dinosaurs) died out. In fact, all animals weighing more than 55 pounds (25 kilograms) seem to have died out!  SCIENTISTS HAVE DIFFERENT HYPOTHESIS: Hypothesis: An asteriod hit the earth.  Effect: Apart from the fires and flooding, this would have caused catastrophic changes in the environment because of the dust thrown up in to the air blocking out sunlight. EVIDENCE: There is a large crater at Chixulub in southern Mexico, which appears to be of the right age, and could have been made as a result of an asteroid hitting the earth. Hypothesis: Volcanoes could have caused catastrophic changes in the environment.  Effect: The dust from volcanoes would have affected the climate, sulphur from volcanoes could have caused immensely strong acid rain, and poisonous substances. EVIDENCE: we know that volcanoes were very active at about this time. Hypothesis: A nearby star exploded as a supernova. Effect: A nearby supernova would have bathed the earth in deadly radiation.  EVIDENCE: NOT FOUND Hypothesis: The first flowering plants appeared during the Cretaceous period, and if dinosaurs ate them they could have been drugged by them. Effect: Could perhaps have wiped out some dinosaurs.  EVIDENCE: not found Flowers poisson ASTEROID IMPACT VOLCANISM SUPERNOVA CLIMATIC CHANGE MAMMALS ATE EGGS Hypothesis: Changes in the Earth's climate caused the mass extinction. Effect: Depends on the particular climate change theory in question.  EVIDENCE: there is some evidence that the Earth cooled at the end of the Cretaceous period. Hypothesis: Mammals ate the dinosaurs' eggs.  Effect: Could perhaps have wiped out some dinosaurs. EVIDENCE: Not found. It does not explain why dinosaurs were very successful for millions and millions of years, during most of which time, mammals were also around.

8. CATERPILLARS EPIDEMIC DISEASE Hypothesis: Caterpillars ate all the plants and there was not enough food for herbivores, and eventually not enough meat for carnivores.  Effect: Could perhaps have wiped out some dinosaurs.  EVIDENCE: This hypothesis does not explain the extinction of marine species, and some may wonder whether caterpillars could really affect every continent on the Earth at the same time to this extent. Hypothesis: The dinosaurs could have been wiped out by a disease epidemic.  Effect: Could perhaps have wiped out some dinosaurs.  EVIDENCE: NOT FOUND My theory is…

9. TIMELINE TIMELINE FORMATION OF THE EARTH Around 4,600 million years ago. WATER APPEARS The Earth cools down and after water appears, it´s the beginning of LIFE. (First single celled then multicelled) Mesozoic era Dinosaurs and other reptiles, like crocodiles, are the dominant creatures. Many reptiles have come back to the seas. There are some extinctions but the most important is the CREATECOUS-TERTIARY MASS EXTINCTION, where dinosaurs and many other creatures are wiped out. PALEZOIC ERA Fish, amphibians, reptiles and mammal.-like reptiles. There are several extinctions and the Trilobites, the Sea Scorpions and many others are wiped out  Do youknow Charles Darwin? Investigateabouthim and writedownyourconclusions: CENOZOIC ERA It´s the mammals´era. 1. Triassic period 2. Jurassic period 3. Creataceous period

10. -WHAT IS IT? It´s something that gives us information about the past. -TYPES: oral sources (from spoken language), graphic sources (images, maps…), written sources (books, letters…) and material sources (bones, tools…). What types of sources are they? What kind of sources do you think we can use to know about the Jurassic time? HISTORICAL SOURCES POEMS SAYINGS SONGS NEWSPAPERS FURNITURE TOOLS Fossils are preserved remains or traces of animals, plants and other organisms. They are generally found in rocks. When an animal or plant dies, its body can get buried into sand or mud. Then, over ages (millions of years), the sand or mud gets compacted, and eventually turns to rock. WHAT´S THE NAME OF THE PESON WHO DOES THIS FOR A LIVING? Imagine how it´s their job like and what tools do they use…
