Hi Ludia, I would like to make a suggestion: pelagornis and argentavis as new cenozoic creatures, two of the largest flying birds ever. It would be epic and I’m sure people will love it!
I was about to suggest just the same thing, including other cenozoic creatures such as the Megalania, the Aurochs, the Dire Wolf and the Gigantopithecus
Another creature I thought of is Witwatia Schlosseri, a giant bat. I hope Ludia reads this!
