Hello my friends here is the start of what I hope to be an enjoyable series for those who like my cephalopod one. This series has been a bit more delayed than I wanted due to certain speculative evolution projects I wished to contribute to but with those done I can finally start this. While thinking of what to do next I considered revisiting trilobites (which I will do eventually as I've mentioned that seed world I'm still working on). But then I thought about it more and wanted to do a decently sized group that I felt didn't get enough love and I hadn't done before.

This led me to decide on making a series on jawless fish which often get shunted to the side lumped in with Ammonites and Trilobites as clades doomed to an inevitable demise at the hands of jawed fish. This view is of course wrong and ignores the fact that there are still a hand full of jawless fish alive to day, albeit a far cry from their former glory. I also decided that instead of leaving extinct forms black and white I would give them color. This was for two reasons. Back when I did my series on ammonites, trilobites, chelicerates and other arthropods I was of the opinion that it was dishonest to depict extinct animals with color as we couldn't possibly know what they were like. Looking back this is stupid and likely due to my autism. However I have a new method for making living animals stand out from extinct ones. But we'll get to that much later on I hope to draw every one I could find sufficient reference material and is considered valid.
