Reference excerpt

In the Presence of Dinosaurs is book that was published in 2000 by John Colagrande and Larry Felder.

Details In the Presence of Dinosaurs focuses predominantly on the dinosaurs of North America over the course of five different time periods and details the flora, fauna, geology and geography of each time period in a manner akin to a naturalist's viewpoint. The book is divided into seven chapters, each supplemented with illustrations regarding the prominent animals and plants in each time and area.

Chapter 1: New World Order The first chapter focuses on the rise of life in North America after the Permian Extinction during the Triassic. The rise of archosaurs as one of the predominant groups is highlighted, along with their competitors, the therapsids. Pterosaurs are shown beginning to take flight. Animals mentioned:

Sharovipteryx (illustrated) Preondactylus (illustrated) Garjainia (illustrated) Eoraptor (illustrated) Cynognathus (illustrated) Megazostrodon (illustrated)

Chapter 2: Veiled Woodlands This second chapter focuses on the areas that became the Petrified Forest during the Triassic. Here, Phytosaurs such as Rutiodon and Rauisuchians such as Postosuchus dominated as the region's top predators and Aetosaurs and Dicynodonts played the role of the local large herbivores. Dinosaurs such as Coelophysis and Fabrosaurs also dwelt here but are considered uncommon animals in the ecosystem. Animals mentioned:

Rutiodon Chinlea (referred to as Chinlia) Placerias Calyptosuchus Desmatosuchus Postosuchus Hesperosuchus Icarosaurus Fabrosaurids (real genus not disclosed) Metoposaurus Eudimorphodon Coelophysis

Chapter 3: Rift Valley The third chapter focuses on the Early Jurassic rift valleys and lake ecosystems. By this time, the dinosaurs now completely dominated the landscape, and their adaptations that allowed them to survive this unpredictable, drought and forest fire-prone environment are discussed. Animals mentioned:

Coelophysis (species unknown) Semionotus Ammosaurus Anchisaurus Dilophosaurus Diplurus Fabrosaurids Trithelodonts (illustrated only)

Chapter 4: Plains Dominion Chapter 4 takes place during the Late Jurassic (Tithonian stage), and focuses on the iconic fauna of the time period, such as Apatosaurus, Allosaurus, and Stegosaurus among others. Also discussed is how the changing of the wet and dry seasons affected the wildlife and how sauropods influenced the landscape. Animals mentioned:

Comodactylus Mesadactylus Apatosaurus Brachiosaurus Camarasaurus Stegosaurus Camptosaurus Othnielia Ceratosaurus Allosaurus Ornitholestes Coelurus Dryolestida (referred to as pantotheres)

Chapter 5: Wandering Shores The fifth chapter deals with the Niobrara Sea during the Campanian Stage of the Late Cretaceous. The speculative habits of animals such as Hesperornis and Pteranodon are examined, and the influence of the sea is discussed. Animals mentioned:

Hydrotherosaurus (illustrated only) Elasmosaurus Cretoxyrhina (illustrated only) Hesperornis Pteranodon Apsopelix Nyctosaurus Ichthyornis Archelon Tylosaurus Ammonites

Chapter 6: Corridor Corridor discusses the biodiversity of the dinosaurs of the Campanian stage of Laramidia, the possible migrations they might have made to feed and reproduce, and how those migrations affected both local wildlife and the environment. Animals mentioned:

Parasaurolophus Corythosaurus Chasmosaurinae Centrosaurinae Hadrosaurus Tyrannosauridae (species not mentioned) Troodon Dromaeosaurus Ornithomimidae Hypsilophodontidae

Chapter 7: Glens of Hell Creek In this last chapter, the impact of Tyrannosaurus on its environment and fellow animals is discussed and how it in turn was affected by its prey. Animals mentioned:

Tyrannosaurus Edmontosaurus Triceratops Ankylosaurus Ornithomimidae Dromaeosauridae Troodontidae

Worked examples

Example 1 — a first encounter with In the Presence of Dinosaurs

Start with the simplest possible case. Write down what In the Presence of Dinosaurs claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to In the Presence of Dinosaurs before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about In the Presence of Dinosaurs ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of In the Presence of Dinosaurs

In research: In the Presence of Dinosaurs appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses In the Presence of Dinosaurs in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: In the Presence of Dinosaurs is common in secondary-school and first-year university syllabi. It links to neighbouring topics 2000 non-fiction books, Non-fiction books about dinosaurs, Paleontology books, so understanding it makes those chapters shorter.
In everyday life: Look for In the Presence of Dinosaurs outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
