"Four thousand years old is too young," Mishka said, dissatisfied. "The dinosaurs on display are surely older."
"Then tell her about the sandhopper. Remember the little Pallas amphipod I once showed you?"
"I do," Mishka remembered.
"Its ancestor originates from the far-away Lake Baikal. Millions of years ago, Mishka, there existed the cold Sea of Yoldia. That ancestoral amphipod used it, and the system of the northern lakes, to reach our parts. Then, after the Yoldia Sea transformed into a chain of lakes, the amphipod appeared trapped in Lake Kenozero. The lake became fresh with years, but the amphipod had managed to adjust, which wasn't easy at all, you know."
"But an amphipod is not a dinosaur," Mishka argued.
"Then read this," Mishka's father gave him a newspaper. "Lake Kenozero has been discovered to be inhabited by crested newt, a rare protected species. Crested newt is able to grow back a missing leg or tail within four months. It can survive the cold quite easily, freezing into ice in winter and coming back to life after spring thaw. A slow and clumsy walker, crested newt is a skillful swimmer and diver. Have a look."
"A mini dinosaur" Mishka nodded in agreement.
"Maybe Mashka is not as mean as she seems? Come on, tell us, Mishka!"
