Name GEOL 104 Dinosaurs A Natural History Video Assignment DUE Tues Nov 15 FC01 Wed Nov 16 0101 Documentaries represent one of the main media by which scientific information reaches the general public For this assignment you ll be looking a series of three different TV documentaries that reflect different approaches and techniques used to uncover the life and death of different dinosaurs As it happens the three documentaries are all about theropods carnivorous dinosaurs I would have liked to have included some herbivorous dinosaurs in this but there aren t as many good documentaries about them yet These videos are available for watching via the ELMS site during the week of Oct 31 Nov 4 Additionally Great American Predator will be available in Dial Access in the NonPrint Media room of Hornbake Library Dial Access is a program by which the videos are shown on a continuous basis during open hours see http www lib umd edu NPRINT dialaccess html for more details There will be online access to at least some of these videos too more information to come The three documentaries are each about one hour long Each has a particular different emphasis focusing on different particular dinosaurs and different approaches to paleontology The documentaries in question are Arctic Dinosaurs Nova PBS 2008 online at http video pbs org video 1022686073 The Four Winged Dinosaur Nova PBS 2008 online at http www hulu com watch 63729 nova thefour winged dinosaur Great American Predator Monsters Resurrected Discovery 2010 on ELMS and in NonPrint Media For each documentary watch the video and answer the questions as you go along You may want to see them more than once if you miss part of the question 1 Name Arctic Dinosaurs Nova PBS 2008 This documentary suffers from some rather crappy and in come cases horribly horribly inaccurate computer dinosaur models But it does take a different look at dinosaurs than the previous documentaries we ve examined Rather than focusing on a particular species this one looks at a particular environment dinosaurs of 70 million years ago early Maastrichtian Age Late Cretaceous Epoch of the North Slope of Alaska 1 How many different species of dinosaurs are represented in the Colville River fossils 2 Hans Dieter Sues discusses the implications of Arctic dinosaurs for dinosaur biology What is this implication In particular what is the significance of the lack of crocodile fossils from the same formations 3 Tom Rich and colleagues are trying to recover fossils from the Liscomb bone bed What sort of approach do they need to do in order to get to those bones What precautions do they need to take 4 What is the most common dinosaur found in the Liscomb bone bed 5 How does the diversity of dinosaurs in Tony Fiorillo s bone bed compare to that of the Liscomb bone bed that Tom Rich is working 6 How does Fiorillo explain the concentration of Pachyrhinosaurus bones at his site That is what events did he speculate happened to produce this concentration 2 Name 7 Robert Spicer uses fossil plants to estimate the paleoenvironment of 70 Ma Alaska What property of leaf form does he use to determine if the climate was warm or cold 8 What match did Spicer find for the climate conditions of 70 Ma North Slope of Alaska a Identical to modern North Slope conditions tundra same average annual temperature as today b Close to modern southern Alaskan conditions temperate average annual temperature of 42 F 30 F warmer than modern North Slope c Close to modern northern California conditions temperate average annual temperature of 62 F 50 F warmer than modern North Slope d Close to modern Guatemala subtropical average annual temperature of 80 F 68 F warmer than modern North Slope e Close to southern India tropical average annual temperature 85 F 73 F warmer than modern North Slope 9 Steve Hasiotis examines trace fossils in order to reconstruct the ancient environment as well Using these trace fossils what time of year and what kind of local environment does Hasiotis reconstruct for this site Extra Credit At 70 Ma how many months of darkness did the North Slope of Alaska get every year 10 How would the dark time affect the food sources for the herbivores How would it have affected the food sources for the carnivores 11 Sues suggests a possible survival strategy for the herbivorous dinosaurs What is that strategy And what problems does Tony Fiorillo see with this strategy for some dinosaurs 12 Anusuya Chinsamy Turan looks at the bone texture of dinosaurs What did she find concerning the hadrosaur bone in particular with year round activity That is did she find that it rested for a long period of time or did she instead find that it had year round activity 3 Name The Four Winged Dinosaur Nova PBS 2008 While the other two documentaries focused on one of the larger carnivorous dinosaurs of its environment this one looks at a little one the aptly named Microraptor Extra Credit What unusual new feature was first discovered in Microraptor 13 What was the paleoenvironment that is the type of habitat that existed in the past of Liaoning 130 million years ago when Microraptor and the other fossils were formed 14 What sort of material formed the sediment that allowed the wonderful preservation of the Liaoning fossils The documentary discusses the work of John Ostrom in the 1960s that modernized the study of dinosaurs and connected dinosaurs and birds 15 Which two fossil genera were the main ones that Ostrom used in connecting birds and dinosaurs Circle the two names Allosaurus Archaeopteryx Deinonychus Hesperornis Ichthyornis Microraptor Nanotyrannus Velociraptor 16 As they discuss in the documentary what very important feature was left off of the raptors of Jurassic Park 17 The documentary mentions that feathers can have important functions other than for flight Name two of the functions they mention with extra credit for a third 18 According to the video what is the function of asymmetrical feathers 4 Name The video discusses the work of Ken Dial about which we will see more of in class 19 True or False Ken Dial showed that baby birds use powered wing flaps to run up walls but that their wings were only used as passive parachutes that is they were not flapped when they jumped off of heights True False Circle the correct answer The program spends some time examine the creation of two alternative models of Microraptor Paleontologists Mark Norell and Xu Xing and artist Jason Brougham sculpt one model from measurements of
