It’s not just the insufficient velocity that makes the penny non-lethal. It’s the combination of the velocity together with its low mass. A 30 to 50 mph fast and 10 lb heavy penny could definitely kill you.
Humans and dinosaurs do coexist right now, today: birds are (technically) dinosaurs.
Birds are decendants of dinosaurs but saying that birds are dinosurs makes Aa much sense as saying humans are fish
Dinosaurs are a defined group of reptiles

Birds are more closely related to some dinosaurs than some dinosaurs were to each other. wiki page
