BABY BIO EXAM 4 STUDY GUIDE print and fold paper in half to quiz yourself QUESTION a specialist who studies the forms of life existing in prehistoric or geologic times represented by the fossils of plants animals and other organisms combines the methods of natural science biology with the methods and findings of the earth science paleontology The first name of a dinosaur discovered sea monster the animal that started the concept that animals were extinct giant lizard similar to a komodo dragon named for the tooth that looked like an iguana tooth A paleontologist that first created the word dinosauria which means fearfully great reptile reptiles in Europe are different than those living today closest relative to dinosaurs The three features of a dinosaur ANSWER Paleontologist Paleobiology Scrotum Humanum Mososaurus Megalosaurus Iguanodon Richard Owen Pterosaurs Three or more sacral vertebrae fused backbone Perforate acetabulum hole in hipbone Three or more fingers Ornithischians bird hipped Saurischians lizard hipped Terrible claw Showed that all dinosaurs are not slow lumbering brutes Small body large brain Two kinds of dinosaurs stood on two toes and looked like a bird this is the dino that fueled dinosaur renaissance 3 characteristics of this Deinonychus when a material degrades the half life if when one half of the material is gone and lets us know when it first existed The giant crocodile 31 000 lbs immense bite force a sea monster not a dinosaur loch ness monster 2 characteristics of these the remains of other organic material produced by an organism but not the actual remains for example burrows feeding marks coprolites eggs where we find our dinosaur remains also found in volcanic rock but less common laces where plants don t grow and where we find HalfLife Deinosuchus Plesiosaurus Fins and gave live birth Trace fossils Sedimentary rocks Badlands dinosaurs none in FL bird shaped hipbones categorized by having a shield barrier or body armor bumps on the backs of dinosaurs The internal cast of a hollow object Fills brain cavities to tell us about fossils and biology dinosaurs with a gap between the front and back teeth ate crocs different toothed lizard has different shaped teeth like a mammal differences in size and shape between sexes found in dinosaurs although we don t know the gender of any dinosaurs they have hundreds of teeth that work together while they eat with new teeth erupting into the mouth all the time have the most evidence of this kind because of things such as bite marks feces and track marks 3 characteristics of these classified by the rim on the bone of the back of the neck this bone was either used for head butting or flank butting beaks shaped like parrot known as the egg stealers because it was thought they wee stealing eggs when in fact their own Oviraptor eggs know shape of skull thick nosed lizard Canadians believed they had a giant nosed horn long necks long tails small beaks and had nose on top of their head how big was this animal Beast footed dinosaur Most closely associated with a bird Smallest saurischia thin hollow bones remains blown up by British in WW2 the fastest dino Could go 40mph or more dino scissor hands therapod that ate plants could tell through teeth had a fearsome huge claw on feet smallest dino with largest brain COMPARED TO WHAT ANIMAL brain size vs body mass a picture of what an evolved dino to a human Ornithischians Thyreopora Osteoderms Endocasts Cerapoda Heterodontosaurus Sexual dimorphism Tooth battery Hadrosaurid or duck billed dinosaur Hundreds of interlocked teeth Self sharpening Crest was NOT used as a snorkel no holes Marginocephalia 140 ft long would not fit in Ruby Diamond Theropod Ceratopsians Oviraptor Pachyrhinosaurus Sauropods Spinosaurus Ornithomimids Segnosaurus Deinonychosauria Troodons Encephaliation quotient Dinosauroid Archaeopteryx Ancient wing Proof that birds lived during the time of Dinos Theropods Teeth hand claws feathers prediction of evolution the first bird found in china 4 things about this bird Where was the first place people wrote about dinosaurs Dinosaurs are related to and pterosaurs However they are mot closely related to even though they act differently and the Deinonuchus are what fueled the dinosaur renaissance believed that all dinos moved like birds mammals Dinosaurs lived over Million years ago we know because of isotopes in volcanic rock Climate was much warmer or colder at that time T or F Crocodiles lived with dinosaurs T or F Largest crocodile was 37 000 lbs Paleontology is found in not biology Dinosaurs were meaning they walked on land T or F Dinosaurs had self sharpening teeth Dinosaurs found with crests were thought to use them for but later discovered that was NOT the case Longest dino recorded was the at 140 feet The Apatosaurus was also named the The tallest dinosaur recorded was the at 56 ft tall T or F Oviraptors had teeth T or F Dinosaurs could live to be as old as humans How long did dinosaurs dominate the planet for T or F we cut open dinosaurs and found that they grew fast and then just stopped T or F dinosaurs had a slow metabolism The smallest dinosaur found was oz The president that was intrigued by dinosaurs was Three possible extinction theories China crocodiles pterosaurs Robert Bakker 65 5 warmer True True geology terrestrial True snorkels supersaurus brontosaurus suroposeiden False they were toothless False no dinosaur lived past 50 years 172 billion years true False it was fast 7 oz Thomas Jefferson 1
