I'm doing some researches for my book. I've read that the impact winter which lead to dinosaurs extinction was 18 months long. Long enough to kill plant life, big herbivorous and big carnivorous. I want something similar for my book, in present times.
An asteroid falls, and we got 18 months of impact winter.
Long ago some animals survived, like flying dinosaurs, because they ate seeds (which last longer than plants). Small mammals ate bugs, etc. You all know the history.
So, doing some research in my region, I found out that puma (quite versatile mammal) not just eat big animals, but smalls too and even bugs. It can live in many biomes as well. Seem like a great survivor, but... it is a big cat.
What do you think? Could a puma survive an impact winter?
