Trilobites are not to blame

Optimistic news for humanity on the brink of global warming: the end of the world is actually not the end. Everything has happened before. And our distant predecessors – trilobites – reached the height of civilization when the continents were... almost completely covered by water, the tallest "trees" were mosses, and bacteria wandered among them feeling like the lords of the land.
These trilobites became the heroes of an exciting tale by Svetlana Lavrova. In a secret school for trilobites, twelve masters convene: an ice age is approaching. Four young students are sent to find a remedy for the Second End of the World. The ice age will come anyway, but the young scouts will make many discoveries. Where the cooling is coming from and where it is heading, who has what chances of survival, can the disaster be postponed and how. They will also prove that the world of living beings is not divided into firsts and lasts: all are important for life on the planet!
In this captivating science fiction tale, Svetlana Lavrova has managed to scientifically narrate about paleontology and the Paleozoic era. A find for beginning researchers!
A spy novel actually becomes a cleverly devised shell for a popular science book about the Paleozoic era (and its Ordovician period). Detailed notes help to understand this period and key archaeological terms and to distinguish real data from the author's assumptions. In the end, the book resulted in a "very-very brief and incomplete encyclopedia of the Ordovician period."
