1 Family Groups Dinosaurs evolved from the class of backboned animals called Reptiles. They are split into two major groups (orders) based on the structure of their pelvis (hip bone). These groups are then divided into suborders and then families depending on similarities in their bone structure. Order One These are called the lizard hipped dinosaurs (Saurichia), which had a pelvis similar to that of a large lizard. It included the following families: a) Giant plant eaters (Sauropods): Diplodocus b) Big meat eaters (Carnosaurs): Tyrannosaurus c) Small meat eaters (Coelurosaurs): Ornithomimus d) Large clawed meat eaters (Deinonychosaurs): Velociraptor...and eventually the true birds. Order Two These are called the bird hipped dinosaurs (Ornithischia), which had a pelvis similar to a modern bird. They were all herbivores and included the following families: e) Horned (Ceratopsia): Triceratops f) Bird-like feet (Ornithopoda): Iguanodon g) Dome headed (Pachycephalosaurids): Pachycephalosaurus h) Plated (Stegosaurids): Stegosaurus i) Armoured (Ankylosaurids): Ankylosaurus. From the dinosaur file see if you can assign two more dinosaur names to each of the nine families above. a) b) c) d) e) f) g) h) i) There is only one other armoured dinosaur in the file. Can you find it?

5 Finding out information from the Dinosaurs Datafile (2) Name(s) In worksheet you were given a lot of help in answering the questions. In this worksheet you have to work out how to do it for yourself, so you will have to think harder, but make the computer do most of the work! Don t forget to use the All Sheets/Subset toggle button to reset between questions if you need to. How many dinosaurs were more than 0 metres long? How many dinosaurs were less 2 than 5 metres long? How many were between 0 metres 3 and 5 metres long? How many dinosaurs were less than 4 the AVERAGE length? a) How many dinosaurs were meat eaters? 5 b) How many of these meat eaters were from the Jurassic period? How many Cretaceous dinosaurs were 6 plant eaters? 0 What was the average length of all the plant eaters? metres What was the average length of all the meat only eaters? metres Most of the Jurassic dinosaurs walked on 2 legs true or false? How many bird-hipped dinosaurs were there in the Cretaceous period? To which group did most of the Jurassic dinosaurs belong? Find the dinosaur that was Lizard-hipped, ate meat, lived in the Jurassic period and was less than metre long. Its name was a) Select the dinosaurs from the Jurassic period that were found in Europe. b) Put these in order of length (smallest first). c) Organise the headings so that you can fill in the table below.
