Descartes can be such a philosoraptor...
A philosophical cousin of the velociraptor, that originated on 4chan, and was adapted from the advice dog meme. It's commonly used as an image macro with a picture of the philosoraptor's head, one talon poised under its chin, as it ponders the deeper questions of the universe.
It is generally accompanied by a riddle, pronoun or philosophical issue, or a parody of one of these, that the philosoraptor is currently mulling over. The text is usually divided, with half the text appearing at the top of the picture, and the other half at the bottom.
