The mystery of dinosaur extinction has led to numerous hypotheses, with the most well-known being the asteroid impact theory. However, Russian biologist Yevgeny Terekhov has proposed a groundbreaking theory suggesting that the extinction of dinosaurs is closely linked to changes in plants during the mid-Cretaceous period. He points out that around 100 million years ago, there was a fundamental shift in insect species, with termites, ants, and bees replacing the original insects. Concurrently, flowering plants began to thrive, altering the balance of the ecosystem. These changes put immense pressure on dinosaurs that relied on specific plants, leading them to shift towards predation and ultimately resulting in their extinction. Terekhov believes that flowering plants may have contained some toxins that had a fatal impact on dinosaurs.
