I am looking for a subreddit with parts of the cambrian, but also jurassic, triassic, and other periods, consisting of dinosaurs, the first arthropods, even the first bacterial life. Where should i search?

For context I’ve been working on a world building project we’re time collapsed in on its self and made a pocket world with various different types of animals and plants now inhabit the same area threw out millions of years apart.

The setting is the channel that separates the UK and France in our world but in mine is currently a massive piece of grassland that’s separated by a small river this is where the main charter of the story will meet a Spinosaurid of some kind.

Just asking for suggestions doesn’t have to be big names just something in the area since I don’t know many prehistoric life around that area that aren’t dinosaurs.

Like the title says, I’m looking for recommendations on comprehensive nonfiction tomes on prehistoric life published preferably within the last five years (and preferably with some cool paleo art). I already know about “The Rise and Fall of Dinosaurs” and its sequel, which many readers seem to find insufferable.

If anybody has some good recommendations, I’m all ears!
