Unit 4- Lesson 6: Let's Go Dinosaur Tracking!

The word "tracks" in this story refers to footprints. This means that the author is using the word "tracks" to describe the marks left behind by someone's feet. This interpretation is supported by the fact that footprints are mentioned as one of the options in the question. Therefore, the correct answer is footprints.

A paleontologist studies fossils and the past. This involves examining and analyzing ancient remains of plants, animals, and other organisms to understand their characteristics, behavior, and evolution over time. By studying fossils, paleontologists can reconstruct the history of life on Earth, including the development of different species, the impact of environmental changes, and the processes of extinction and adaptation. They use various scientific techniques and tools to gather data and interpret the information contained within fossils, providing valuable insights into the Earth's past and the evolution of life.

Limestone is a type of rock. It is a sedimentary rock that is mainly composed of calcium carbonate. Limestone is formed from the accumulation of the remains of marine organisms such as coral and shells over millions of years. It is commonly used as a building material and in the production of cement.

Roland Bird discovered old footprints.

When you analyze something, you examine it in detail to understand its components, structure, or nature. This involves a systematic and thorough investigation of the subject matter. By studying it, you gain knowledge and insights about the object of analysis, enabling you to make observations, draw conclusions, and make informed decisions based on the information gathered. Therefore, "study it" is the most appropriate answer as it accurately reflects the process of analyzing something.

A canteen is like a bottle because it is a container used to hold and carry water. Just like a bottle, a canteen is portable and designed with a cap or lid to prevent leakage. It is commonly used by hikers, campers, and outdoor enthusiasts to stay hydrated during their activities.

Sauropod tracks indicate that young sauropods stayed in the middle of the herd. This suggests that young sauropods traveled alongside their parents and other adult sauropods, rather than flying in the air or riding on their parents' backs. Staying in the middle of the herd would have provided protection and safety for the young sauropods, as they would have been surrounded by the larger, more experienced adults. This behavior is similar to what is observed in many modern-day animal species, where young individuals stay close to their parents or within a group for protection and guidance.

The correct answer is that tracks can tell us a lot about dinosaurs. This is because dinosaur tracks provide valuable information about their size, behavior, and movement patterns. By studying tracks, scientists can learn about the different types of dinosaurs that lived in an area, their speed, and even their social interactions. Trackways can also provide insights into the environment in which dinosaurs lived, such as the presence of water or the type of vegetation. Overall, tracks are a crucial source of evidence that helps scientists understand and reconstruct the lives of dinosaurs.

Roland Bird knew that the tracks in San Antonio were not elephant tracks because they were too old. This suggests that the tracks had been there for a long time and could not have been made by elephants, as fresh tracks would indicate recent elephant activity.

When dinosaur tracks are found bunched together, it suggests that they traveled or hunted in packs. This is because if the tracks were made by a single dinosaur, they would be more spread out. The close proximity of the tracks indicates that multiple dinosaurs were moving together, which is commonly seen in pack animals. Therefore, the presence of bunched tracks implies a social behavior among dinosaurs, such as traveling or hunting in groups.

The correct answer is "Some dinosaurs moved quickly." This means that not all dinosaurs moved quickly, which surprised the scientists. It suggests that there was a variation in the speed at which different dinosaurs moved, challenging the assumption that all dinosaurs had similar speeds. This finding could have implications for understanding the behavior and locomotion of dinosaurs.

Scientists used to think sauropods lived in water because they believed that the sauropod's feet were too weak to support its massive body weight on land. They hypothesized that the buoyancy of water would alleviate the strain on the sauropod's feet and allow it to move more easily. However, further research and fossil evidence have since disproven this theory, showing that sauropods were indeed capable of walking on land.

The age of the footprints is not used to figure out a dinosaur's speed. Instead, the distance between the footprints and the size of the footprints are used to determine the speed of a dinosaur. The distance between footprints can indicate the stride length, which is related to speed, while the size of the footprints can provide information about the size and weight of the dinosaur, which can also affect its speed.

The correct answer is "In a coal mine." This means that the hadrosaur tracks were discovered in a coal mine. It is possible that the coal mine was located in an area where there were once forests or near an ocean, but the specific location mentioned in the story is the coal mine.
