Dinosaurs Lately - Marginocephalians (Summer 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.

Episode 4 - Marginocephalians (Summer 2025).

Dinosaurs Lately is a companion show to the Juras-Sick Park-Cast, the podcast where guests chat with me about Michael Cricthon’s 1990 novel Jurassic Park, and also not that, too. If you’d like to be a guest on that show, you can reach me at ryansrogers-at-gmail.com. These podcasts are part of the Spring Chickens banner of amateur intellectual properties including the Spring Chickens funny pages, Tomb of the Undead graphic novel, the Second Lapse graphic novelettes, The Infantry, and the worst of it all, the King St. Capers.

You can find links to all that baggage in the show notes, or by visiting the schickens.blogpost.com and you can connect and follow on Facebook, at Facebook.com/SpringChickenCapers, on Youtube by searching for the “Juras-Sick Park-Cast podcast”, on Tumblr @misterrogers22 on X at @RogersRyan22 or on BlueSky at ‪@rogersryan22.bsky.social.

Thanks for tuning in! I hope you feel you’re all caught up on marginocephalians … for now!

Until next time!
