The other survivors tell Mikoshiba that he's still alive, but he can't greet them, because they're afraid of what's going to happen to him. They're also afraid of the other guys, who've been coming in and out of the camp, and they don't know how to greet them. Mikashiba tries to calm them down by telling them that there's a new species of elephant that's been around for 56 million years, and that it's not like the rhinos are any different from them. He also tells them that the only skull they've found is a partial one, so they can use it as a starting point to look at other extinct animals, like sea cows and elephants, to figure out where they came from and what they ate and looked like. They can also look at the shape of their jaws, which is used to classify extinct animals into groups based on their appearance, diet, and age of existence. They also use their jaws' shape to look up extinct animals that have the same features, like dogs and cats, and to predict their future appearance and behavior.
