An unusual thunderstorm had been in the process of slowly developing since the late afternoon. And this one night’s event was about to change everything. Lazy flashes of green lightning flickered in the clouds in the sultry evening air, As the greenish-tinted rain started to pour down, smoke started rising from the ground. Within the former territory of the now extinct tropical garden, primitive amphibian like creatures started digging from underneath the ground and eventually crawling to the surface. Attracted by the warmer temperatures, moist environment, plentiful bodies of water and numerous tiny invertebrates, more of them had started moving in beforehand and eventually distributed themselves throughout the sheltered area. Their lifespan was relatively short but it was longer than the invertebrates that had previously been the sole occupants. They were dark colored with yellow luminescent spots on their bodies and tails in a row. The lake began to bubble greatly as the rainwater poured into it. Tiny tadpoles and eel-like larva with flowery gills were swimming about. New varieties of insects both carniverous and plant eating were also moving in to the sheltered area and establishing themselves for the first time.
Further south in the tropics and neotropical areas, the warm, rich environment was especially suitable for amphibians. As they gradually evolved, there were a few species that became true giants at the top of the food chain (apex predators) growing to almost 30 feet in length. They were masters of camouflage feeding on smaller amphibians, fish, and whatever else was unfortunate enough to get in their way. The early amphibians in this area were usually dark green but others were brown, black and dark purple. Further north, they were less able to adapt to the colder climate and as a result, they did not achieve the large sizes of their tropical counterparts. The tropical giants did not evolve in the sheltered area which was also cooling down as well.
During the period that the Tropical Garden flourished, there was a section in the garden that was populated by wild banana plants with small ponds interspaced in between them. These were the secret ones that stayed in the shadows and whose influence would not yet be fully realized until the Age of Reptiles. Tiny primitive, yellow wormlike creatures with fins swam about like eels hunting their prey. Later on, they evolved into bright yellow salamander like amphibians in the vast marshes where the Tropical Garden once stood. These bright yellow salamander like creatures were among the early ancestors that would gradually evolve into the ferocious Bananasauros, the yellow terror of prehistory.
Other changes occurring on the Planet Gaus as well. Closer to the equator in the topics and subtropics there were other changes as well. A vast area of wetlands (i.e. swamps and marshes) had developed with plants that were adapted to growing in this environment and would feed on insects to make up for the lack of nutrients in the soil. One of them would be the ancestor of the infamous carnivorous plant of the Southern Bootheel.
