it is funny when something isn’t pterodactyl and the blogger calls it that
e.g. maybe a bird, or a whale, or whatever
the funny is directly proportional to how unlike a pterodactyl it is
other pterosaur in one of the families that are colloquially called “pterodactyl” but not the Pterodactylidae family: unremarkable
Archaeopteryx: annoying
modern bird: funny
whale: hilarious
bowl of potato salad: i might actually suffocate from laughing
