Weirder still, some new fossils from the Cretaceous have directly captured this nightmarish behaviour for the first time. We take a look at these interesting fossils, their potentially shady origin story, and their implications for reconstructing evolution of this unsual parasitic behaviour. Side-note: did fungus cause the extinction of dinosaurs? The main paper discussed this week is by Yuhui Zhuang and colleagues "Cretaceous entomopathogenic fungi illuminate the early evolution of insect–fungal associations" published in Proceedings of the Royal Soceiy B in June 2025, ( https://doi.org/10.1098/rspb.2025.0407) , free version here . ## Actions - request_transcript: `POST https://stenobird.com/v1/public/podcasts/the-fossil-files-7375611/episodes/cretaceous-zombie-ants/transcription-requests` — Idempotently request low-priority transcript generation for this episode. - read_markdown: `GET https://stenobird.com/podcast/the-fossil-files-7375611/cretaceous-zombie-ants.md` — Read the agent-friendly Markdown representation of this episode resource.
