Frogs formerly coexisted with dinosaurs. The North Sea covered half of Germany 45 million years ago. It's astounding to believe that these tiny organisms survived the annihilation of the dinosaurs. However, a lower degree of mass death did occur in what is now known as the Geiseltal region of central Germany, and the cause has long been unknown.
Hundreds of frog fossils were discovered in a mass burial in Geiseltal's 45-million-year-old swampy coastlands, and experts have been baffled as to why they were there for decades. However, my research team discovered an explanation: they perished from tiredness when mating.
We also discovered evidence that current frog and toad mating behavior stretches back at least 45 million years, as mass grave frog fossils from other sites display similar...
