When was the Great Ordovician Biodiversification Event? (GOBE)?
Daniel Fischer posted a topic in Questions & AnswersHello, I have a question about the great ordivician biodiversification events (GOBE). I know this series of events happened between the late cambrian and the late ordivician but are there more specific dates for it? For example like the great dying was about 250 million years ago. I couldn't find anything more specific then late cambrian to late ordivician but if you know something more specific or you know that there isn't a more specific date please tell me, I would love to know!
