Good day!
I would like to ask, which would be most dangerous for a human (say, time
traveler) in the end-Cretaceous world:
1. Large and mid-sized theropods (Tyrannosaurus, Dakotaraptor)
2. Smaller theropods (Acheroraptor, Anzu...)
3. Large herbivorous dinosaurs; e. g. protecting nests (Triceratops,
Ankylosaurus, Edmontosaurus...)
4. Non-dinosaurian vertebrates (crocodiles, pterosaurs, sharks, mammals)
5. Invertebrate parasites (both ecto- and endo-, like ticks)
6. Microoorganisms (Trichomonas? Viruses, bacterial patogenes, etc.)
7. Environmental effects (volcanic activity, poisonous gases, earthquakes,
floods)
8. Well, of course...rare, but devastating large impacts.
Thank you in advance, Tom
