Most corniculate is a term that describes something that is unusually or excessively horned. If you're looking for synonyms that convey a similar meaning, you may want to consider using words like crested, antlered, or horned. Other options might include crowned, pointed, or protuberant. Depending on the context in which you're using the word, you might also consider using alternative phrasing or descriptive language to convey the same idea. For example, if you're describing the head of an animal with particularly impressive horns, you might simply refer to it as having a "majestic" or "imposing" appearance.
