This comic explores the seeming paradox that certain extinct prehistoric species which are popularly thought of as being "dinosaurs" are, from a strict taxonomic viewpoint, not. It also takes into account the fact that all bird species are descended from dinosaurs and thus - again, from a strict taxonomic viewpoint - are themselves dinosaurs as well. To illustrate this, Randall provides silhouettes of dinosaurs, of entities that are widely thought of as dinosaurs but are not, of entities that are ''not'' widely thought of as dinosaurs but ''are'' (i.e., birds), and, lastly, of entities that are neither dinosaurs nor thought of as dinosaurs (which is funny because it's so all-encompassing).<br />
<br />
* Silhouettes in "seem like dinosaurs / are dinosaurs": stegosaurus, triceratops, tyrannosaurus, diplodocus, velociraptor<br />
* Silhouettes in "don't seem like dinosaurs / are dinosaurs": penguin, ostrich, stork, pigeon, falcon<br />
* Silhouettes in "seem like dinosaurs / are not dinosaurs": mosasaur, pteranodon, dimetrodon, plesiosaur, quetzalcoatlus<br />
* Silhouettes in "don't seem like dinosaurs / are not dinosaurs": squirrel, stapler, pineapple, human, bicycle<br />
<br />
The title text is a further joke about taxonomy, predicated on the assumption that staplers are biological organisms (which they are not){{citation needed}}, and can thus be sorted into taxa. ''Pseudosuchia'' is in fact the clade that encompasses all crocodilians, and staplers bear a certain resemblance to the open jaw of a crocodilian.<br />
