Did you know that our globe has been a single landmass three to six times in its lifetime, per geologists? I knew about Pangaea over 175 million years ago, but while doing prehistoric story research, I learned about 5 other times: Pannotia nearly 600 million years ago; Rodinia 1.1 billion years ago; Columbia (Nuna) nearly 1.8 billion years ago; as well as Kenorland and Vaalbara sometime between 2.5 and 3 billion years ago! #academia #stem #research #writing #amazingfacts #didyouknow @nelming
