Dinowars

Dinowars: The Jurassic War of the Worlds is a comic book from Antarctic Press. It centers on Earth today beset by dinosaurs that escaped into space to avoid the ice age and have now returned to claim the world as their own, mirroring the original The War of the Worlds. The comic is written and illustrated by Eisner-nominated artist Rod Espinosa.

Taxonomic Hierarchy & Evolutionary Notes

• Clade Synapsida (Stem-Mammals / Non-Reptiles): Dimetrodon (Sphenacodontidae) and Lystrosaurus (Dicynodontia). While Bulbasaurus is named after a famous character, it belongs to the same ancient group of dicynodonts.
• Class Mammalia (True Mammals): Alphadon (Metatherian / early marsupial relative).
• Prehistoric Fish (Non-Sharks / Sharks): Dunkleosteus is an armored placoderm fish (not a shark), while Otodus megalodon is a true prehistoric megatooth shark.

📜 Master Dataset & Classifications: Order Pterosauria

Continuing the master chronological data spreadsheet for the flying Order Pterosauria under the explicit narrative direction of Teodora Villavicencio (from Legend Quest: Masters of Myth). Because flying creatures require light, hollow bones, their weight classes sit dramatically lower than terrestrial animals despite their massive wingspans.
