I haven’t posted any new work in a while, so I thought I should post a work in progress. I’ll probably only end up making one book this summer because I ended up using this time to reprint some previous books. It’s the sequel to “The Cambrian”: the Ordovician and Silurian. I originally planned on doing a separate book for each period, but these two periods are very similar in terms of fauna so I merged them into one book. Compared to my last prehistoric book, this took me longer to research.
