October 14Dinosaurs Lately - Tyrannosaurs Pt. 1 (Fall 2026)
Thanks for tuning into the Dinosaurs Lately podcast, the dinosaur podcast that features periodic updates recapping the latest news on the dinosaurs. This is the podcast that targets a type of dinosaur and tries to catch you up on everything that’s been published on them … lately.
The goal is to keep up with all the dinosaurs news, even when I’m not publishing new episodes of the Juras-Sick Park-Cast. If you’re interested in this sort of thing – I hope it helps you feel … up to date.

Thanks for tuning into the Dinosaurs Lately podcast, the dinosaur podcast that features periodic updates recapping the latest news on the dinosaurs. This is the podcast that targets a type of dinosaur and tries to catch you up on everything that’s been published on them … lately.
The goal is to keep up with all the dinosaurs news, even when I’m not publishing new episodes of the Juras-Sick Park-Cast. If you’re interested in this sort of thing – I hope it helps you feel … up to date.

EPISODE 7 - SAUROPODOMORPHS (WINTER 2025)
Thanks for tuning into the Dinosaurs Lately podcast, the dinosaur podcast that features periodic updates recapping the latest news on the dinosaurs. This is the podcast that targets a type of dinosaur and tries to catch you up on everything that’s been published on them … lately.

The goal is to keep up with all the dinosaurs news, even when I’m not publishing new episodes of the Juras-Sick Park-Cast. If you’re interested in this sort of thing – I hope it helps you feel … up to date.
