That doesn’t affect max size inference. It’s obvious that the largest big cats in the past were larger than the largest ones today, regardless of smaller ones whose fossils didn’t survive for eg
No reason to think present cats are max size. Might be larger cats in the future just as there were larger cats in the past. Present is only one slice of time.
