Last Day of the Dinosaurs

Last Day of the Dinosaurs is a earth science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Last Day of the Dinosaurs rather than just read about it. In short: Last Day of the Dinosaurs is a 2010 Discovery Channel television documentary about the K-T extinction, which resulted in the extinction of the non-avian dinosaurs. It portrays the Alvarez hypothesis as the cause of extinction.

Key takeaways

  • Last Day of the Dinosaurs belongs to earth science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Last Day of the Dinosaurs to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Last Day of the Dinosaurs from memory before moving on to harder problems.

Reference excerpt

Last Day of the Dinosaurs is a 2010 Discovery Channel television documentary about the K-T extinction, which resulted in the extinction of the non-avian dinosaurs. It portrays the Alvarez hypothesis as the cause of extinction. The documentary was released on August 28, 2010 and narrated by Bill Mondy.

Production of the film The dinosaur models created for the 2009 series Clash of the Dinosaurs were reused for this program. The Parasaurolophus model was used for Charonosaurus (even though the legs of Charonosaurus were shorter than those of Parasaurolophus). The Deinonychus model was used for Saurornithoides (rather inaccurately, as Saurornithoides was slenderer than Deinonychus), and the Sauroposeidon model was used for Alamosaurus (even though Alamosaurus had different proportions than Sauroposeidon). The same Tyrannosaurus rex, Triceratops, Ankylosaurus, and Quetzalcoatlus models were also used. These models were placed upon different backdrops most of the time than those used in Clash of the Dinosaurs.

Plot In the Pacific Northwest, at the end of the Maastrichtian stage, a Quetzalcoatlus spots an unguarded T. rex nest and consumes several young babies. The father T. Rex is hunting when his acute sense of smell alerts him to the intruder and he runs back to the nest. The Quetzalcoatlus' huge wings hamper its escape in the forest as the T. rex bites its foot. The Quetzalcoatlus pecks at the T. rex's eye and flies away. One hatchling survives the attack. Two T. Rexes hear a mating fight between two Triceratops and attack the loser. Working together, they bring down the Triceratops and eat it. A herd of Alamosaurus search the plains of Mexico for food. A female lays a clutch of eggs as a large asteroid hits nearby, sending debris into the air. The explosion heats the air to hundreds of degrees as burning debris rains down. A magnitude 11 earthquake and blast wave finishes off the last of the Alamosaurus. Some eggs survive, buried under the soil. In Mongolia, a herd of Charonosaurus reside by a watering hole, where the females lay their eggs. A Saurornithoides steals an egg, but is confronted by the mother. A second Saurornithoides forces the Charonosaurus to flee. The two predators chase their prey and bring her down. The asteroid impact has caused an ejecta cloud. As it approaches the pacific northwest, the earthquake arrives and decimates the area. A mated pair of Quetzalcoatlus try to fly away but are caught in the shower of debris, which burns holes in their wings. A pair of Triceratops make it up into the mountains, only to be burned alive by the ejecta cloud. The heat of the ejecta cloud ignites fires around the world causing a firestorm. Large dinosaurs, including a T. rex, a group of Triceratops, and an Ankylosaurus flee while smaller animals hide underground. The female Quetzalcoatlus flies away as the firestorm consumes the forest. Forty-five minutes after impact, the ejecta cloud rolls into Mongolia from the east, increasing the temperature by several degrees every second until it reaches 300 °F (150 °C). Three Charonosaurus and a pair of Saurornithoides shelter in a cave. The temperatures return to normal after five hours, and as the pair of Saurornithoides run outside to feast on the corpse of a Charonosaurus, two surviving Charonosaurus travel to the watering hole, while the third Charonosaurus remains in the cave. The dramatic temperature shift causes a huge sandstorm. The Saurornithoides survive by hiding behind their prey. The two other Charonosaurus suffocate in the storm. The storm passes, and the last Charonosaurus heads to the watering hole. The Saurornithoides find the Charonosaurus taking a drink and one of them attacks the Charonosaurus, but after a struggle, the Charonosaurus collapses on top of it, killing it. The remaining Saurornithoides cannibalizes its companion. Four days since impact, food is in short supply across the planet, only fungus provides growth. In the Pacific Northwest, four Triceratops head towards an island untouched by fire. A megatsunami causes the water to recede and form a bridge. Three Triceratops cross the bridge. The remaining female Quetzalcoatlus lands and eats a stranded fish, just as the 300-foot (90 m) wave races towards shore. She and the three Triceratops are drowned. Ten days on only a few dinosaurs remain. In Mongolia, the Charonosaurus is killed by hydrogen sulfide gas rising from the watering hole, due to a volcanic eruption. The Saurornithoides runs to the dead Charonosaurus, but is also killed by the toxic gas. Some dinosaurs patrol the grey wasteland of the Pacific Northwest. An Ankylosaurus, a Triceratops, and a T. rex fight and all are killed. In Mexico, an Alamosaurus egg, sheltered underground, hatches. However, crippled by inbreeding and disease, the tiny population of dinosaurs disappears. Insects, other arthropods, and small reptiles took shelter underground. Crocodilians, amphibians and fish survived under water, and birds flew or swam away from disasters. Mammals hid in burrows and, with their adaptability and faster reproduction, outlasted the apocalypse. As the ejecta cloud cleared and sunlight returned to the Earth, plants, especially ferns, began to flourish once more. Over the 65 million years after the dinosaurs disappeared, mammals grew to dominate the planet, leading to the evolution of humans.

Worked examples

Example 1 — a first encounter with Last Day of the Dinosaurs

Start with the simplest possible case. Write down what Last Day of the Dinosaurs claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In earth 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 Last Day of the 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 Last Day of the 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 Last Day of the Dinosaurs

In research
Last Day of the Dinosaurs appears in earth 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 Last Day of the 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
Last Day of the Dinosaurs is common in secondary-school and first-year university syllabi. It links to neighbouring topics 2010 American films, 2010 Canadian films, 2010 films, so understanding it makes those chapters shorter.
In everyday life
Look for Last Day of the 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.
