Worst Prehistoric Animals
For creatures we are not the fan of or could impact modern species. Feel free to add any prehistoric creatures that you disliked and/or the creatures that would have an impact in today's world, it has to be a real prehistoric creature (like Carnotaurus, etc, not fictional ones like goku and such).
Worst because the hatchlings make annoying sounds similar to bear cubs, and the real Saltasaurus hatchlings might have sound like bear cubs.

It is just an oversized shark, nothing is unique about this Cenozoic fish.

Why does it look like a devil from fiction? I don't know why.

It would be really annoying if alive today especially if they steal food like seagulls.

It is just a lion only living in the Americas.

This extinct gigantic Ice Age vampire bat would cause problems in today's world if they drank blood out of domestic livestock and if they spread modern diseases like rabies.
I didn't knew that this existed

It's just an oversized version of today's condors and vultures, I mean, what's so exciting about basically just oversized versions of today's animals?

It is just a large monitor lizard.

It is just an oversized lion-sized cheetah.

It is just a Mesozoic counterpart of modern great white sharks. What's so exciting about that?
