{{w|Bird}}s are commonly considered to be a separate {{w|class (biology)|class}} of {{w|tetrapods}}. However, this classification is false according to {{w|phylogenetic taxonomy}}. Taking into account that birds developed around {{w|Late Jurassic|150 million years ago}} out of small {{w|theropod}} dinosaurs, birds along with crocodiles are indeed the remaining representatives of the {{w|Archosaur|archosaur clade}}. This premise appeared also in comic [[867: Herpetology]].

This relation between birds and dinosaurs is depicted in the comic in a {{w|cladogram}} which shows that ''{{w|Tyrannosaurus rex}}'' is more closely related to the common {{w|sparrow}} than to ''{{w|Stegosaurus}}''. Not only do the former share a phylogenetic branch, but ''T. rex'' also lived around 80 million years ''after'' ''Stegosaurus''. The concurrence of both species in popular culture is a widespread error. ''T. rex'' is also much more alike to modern birds than to other dinosaurs in terms of anatomy. This relationship was pointed out on the [http://www.sciencemag.org/content/340/6133/690 Science] journal the week of the comic.

The comic draws the conclusion that if birds must in fact be considered modern dinosaurs, the hunting practice of birds of prey (specifically, the {{w|peregrine falcon}}) is consequently a dinosaur fight. For an inveterate dinosaur aficionado like [[Randall]], this fact must make the modern world much more attractive.
