Thumbnail & Title Assistance Requested.

Okay, so tomorrow I hope to publish a video on 10 prehistoric animals that were the largest of their kind. The issue? I can't decide on a thumbnail or title! Below are two thumbnail options I've made so far (yes, I'm aware neither are that impressive, but I'm experimenting with using "cartoony" animals in my videos and since this is the first one of those, it's bound to not be great), and as for titles I've thought of a handful of options but the real standouts are: 1) "10 extinct animals that were the LARGEST of their kind," "A Whale-Sized Dinosaur?! & Other COLOSSAL Fossils", and 3) "10 COLOSSAL animals that once ruled Earth." (Once again, I'm aware none are that great). Sooo... of these options, which do you like best, or alternatively, do you have any other suggestions for a thumbnail or title idea? Thanks again as always!

Okay, so I think I'll go with one of these two thumbnail + title combos. I'll decide in the morning I suppose because it's too freakin' late lol

I would go with the first thumbnail.
Dont really have any suggestions for title but I would go with 10 of the largest prehistoric animals of all time If i were to pick between the two.

That was my preferred combo as well, but I wasn't sure if it'd work so I separated them. Thanks!
