So maybe we should just call it a grotesque? I look up the definition of grotesque and one of the points is this: the grotesque forms on Gothic buildings, when not used as drain-spouts, should not be called gargoyles, but rather referred to simply as grotesques, or chimeras.
Look up chimera and you'll find this: a fantastic, mythical or grotesque figure used for decorative purposes. Yep. That seems to fit. However, that's not what the little girl said to her mother as they passed by. She pointed up at it and said, "Look at that grumpy dinosaur" as if she were scolding him. Call it what you want.
