Welcome, mate. Always been interested in Extinction Events, and this article caught My eye so of course I immediately thought of you and your interests. :)
Hope you find some tidbits worth pursuing in the article referenced.
Cheers!
JimSea had posted another article about bird survival of the K-T extinction boundary, and I’d pinged that to the same two lists, but this really was a good take on what I think is probably the same underlying story.
After the asteroid crash 65 or 66 million years ago, also known as K-T boundry there must have been one huge ozone hole. The creatures that survived generally were small, probably lived in dens (like mammals), under embankments, (crocodiles), in trees and underbrush, like birds, or had protective shells like turtles, or feathers like birds. Thus they did not die of severe sunburn as probably did those big and small dinosaurs that had skin.
