    Lol yeah, I'm sorry, I know that's not even remotely long time for any species overall, I meant...I guess I'm not really sure how I exactly meant that, and how I can specify it, but I WAS thinking about Dino's, and I guess just the things that DIDNT last indefinitely, but ended up either dying out(environmental or other natural changes. Like food source changing; megalodon/basilosaurus/me if Taco Bell closes), or evolving into something else. Does that make sense?
