1. Jakie dowody znaleźli naukowcy, że niektóre grupy dinozaurów podróżowały w grupach? Narysuj obrazek do poparcia swojej odpowiedzi.

Answer: The best evidence for how dinosaurs traveled comes from trackways, or sequences of fossilized footprints. From trackways, scientists can learn whether dinosaurs traveled individually or in packs, how many traveled together, which dinosaur led the herd, and even how fast they traveled. Trackways from multiple dinosaurs can reveal that they were in a herd if the tracks appear to have been made at the same time and are in the same direction. Some tracks show where dinosaurs moved side-by-side, or where the animals’ paths undulated back and forth together.

2. Wyjaśnij, jak naukowcy szacują inteligencję dinozaura.

Answer: First, scientists estimate the size of a dinosaur’s brain based on the size of its skull. Sometimes they use CAT Scan technology to reconstruct the dinosaur’s brain. Then they estimate the dinosaur’s intelligence based on the size of its brain relative to its body size. They also consider the size of certain parts of its brain, since different parts of the brain relate to different senses or aspects of intelligence.
