Unfortunately the Pentecopterus had taken a liking to my camera and ran off with it. So that's all for #HotAmmoniteAugust folks! And thanks for tuning in! Thanks to

@ddinodan for coming up with this art prompt, it ended up being super fun to do!

GUESS WHAT…. you can now pre-order the next book in the Earth Before Us series: Ocean Renegades! More non-Amazon options here

This book takes Ronnie and her weird neighbor Miss Lernin back to the time before the age of dinosaurs, when strange beasts ruled the sea and land. Giant bugs, giant fish, giant fungus, uh, regular-sized synapsids… all these incredible creatures and more! I am very proud of how pretty this book is so you should buy it, it will bring you great joy and teach you about a lot of animals you never knew existed.

If you don’t know about the Earth Before Us series, check out the first book, Dinosaur Empire! which was release last year!

Pentecopterus, the oldest described eurypterid (sea scorpion).  It’s named after an ancient Greek warship called the penteconter, apparently due to similarities in shape and “predatory behavior”, which is not a phrase I’d generally associate with a warship but fine, biologists, I’ll let it slide.

Pentecopterus could be up to 6 ft long, making it one of the largest arthropods ever, just edged out by our old friend Jaekelopterus.  From the Ordovician.
