Answer to questions: WHERE THEY LIVE, HOW THEY ARE BORN, WHAT THEY EAT, BODY SHAPE, ACTIONS AND SPECIAL FEATURES. TIMELINE OF THE EARTH (basic). EVOLUTION AND FOOD CHAINS. GEOGRAPHY OF CONTINENTS. HYPOTHESIS OF EXTINCTION (debate and scientifical process) DIET AND FEATURES HISTORICAL SOURCES o o o o o o o o OBJECTIVES Distinguishing the basic groups of animals. Calssifying them by different features and characteristics. Creating a timeline of the different eras and the most important events. Understanding the time measurements. Understanding the evolution and the consequences of it. Being critical about scientifical theories and using the scientifical method to create a supported opinion. Identifying physical features to classify animals by their diet criteria. Knowing the job of a paleontologist and understanding how they study the past. ASSESMENT CRITERIA Reconocer los grupos básicos de animales. Clasificar los animales según sus características. Describir las características de los animales que le rodean así como de otros ya extintos. Comprender los cambios naturales que se han producido a lo largo del tiempo y reconocer consecuencias evolutivas. Conocer la labor del paleontólogo, así como las herramientas y fuentes que usa. Crear un eje cronológico de la Tierra. Conocer las hipótesis sobre la extinción de los dinosaurios así como aplicar el método científico para desarrollar una actitud crítica en torno a nuestra opinión. 2 DINOSAURS DIET Sometimes, when we are very lucky, we can learn about dinosaurs' diets and lifestyles directly from fossils. •Some types of dinosaurs ate only meat ("carnivores") •some ate only plants ("herbivores") •And some ate both plants and meats ("omnivores"). Scientists have sometimes found fossilized dinosaur bones, complete with fossilized stomach contents. We know for example that Baryonyx was a fisheater, and that Coelophysis probably 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: 3 OTHER ANIMALS IN THE DINOSAUR WORLD There´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 4 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 FORES T SEA 5 CLASSIFY THEM!: NAME OF THE ANIMAL WHAT DOES IT EAT? (herbivore, carnivore, omnivore) Choose one animal of each category (amphibians, birds, fish, mammals, invertebrates and reptiles) and complete: WHERE DOES IT LIVE? (Place + Wild/Domestic) HOW IS IT BORN? (oviparous, viviparous or mammal) NAME SPECIAL PARTS OF ITS BODY SPECIAL ABILITIES (fly, slither, jump, wiggle…) BODY SHAPE (vertebrate or invertebrate) 6 WHAT HAPPENED?? Dinosaur Extinction Dinosaurs 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: ASTEROID IMPACT 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. VOLCANISM SUPERNOVA Hypothesis: Volcanoes could have caused catastrophic changes in the environment. Hypothesis: A nearby star exploded as a supernova. Effect: The dust from volcanoes would have affected the climate, sulphur from volcanoes could have caused immensely strong acid rain, and poisonous substances. Effect: A nearby supernova would have bathed the earth in deadly radiation. EVIDENCE: we know that volcanoes were very active at about this time. EVIDENCE: NOT FOUND CLIMATIC CHANGE Flowers poisson Hypothesis: Changes in Hypothesis: The first the Earth's climate flowering plants caused the mass appeared during extinction. the Cretaceous period, and if Effect: Depends on the dinosaurs ate them particular climate they could have been change theory in drugged by them. question. Effect: Could perhaps EVIDENCE: there is some evidence that the have wiped out some dinosaurs. Earth cooled at the end of the Cretaceous EVIDENCE: not found period. MAMMALS ATE EGGS 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 7 around. CATERPILLARS EPIDEMIC DISEASE Hypothesis: Caterpillars ate all the plants and there was not enough food for herbivores, and eventually not enough meat for carnivores. Hypothesis: The dinosaurs could have been wiped out by a disease epidemic. 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 PROS CONS I THINK Effect: Could perhaps have wiped out some dinosaurs. EVIDENCE: NOT FOUND My theory is… 8 TIMELINE FORMATION OF THE EARTH WATER APPEARS PALEZOIC ERA Mesozoic era The Earth cools down Dinosaurs and other reptiles, and after water appears, Fish, amphibians, reptiles and like crocodiles, are the mammal.-like reptiles. Around 4,600 it´s the beginning of dominant creatures. Many million years ago. LIFE. There are several extinctions reptiles have come back to the seas. and the Trilobites, the Sea (First single celled then Scorpions and many others multicelled) There are some extinctions are wiped out but the most important is the CREATECOUS-TERTIARY Do you know Charles Darwin? Investigate about him and write down your MASS EXTINCTION, where conclusions: dinosaurs and many other creatures are wiped out. CENOZOIC ERA It´s the mammals´era. 1. Triassic period 2. Jurassic period 9 3. Creataceous period HISTORICAL SOURCES -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? POEMS SAYINGS SONGS NEWSPAPERS FURNITURE TOOLS What kind of sources do you think we can use to know about the Jurassic time? 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… 10
