Ammonoidea Illuminated brings (back) to life some of the most bizarre, rare, impossible, and geologically important fossil cephalopods that lived between the Devonian and Cretaceous periods


These drawings are some of the first ever ammonoid reconstructions produced using geological cues as much, if not more than, artistic license. Each species is studied for its internal structures, the sedimentological and sometimes, tectonic data for the rocks in which it is found, and its most similar cephalopod counterparts are identified after careful consideration. 


They are exhibited at institutions worldwide, and were recently awarded Special Mention in the International Award on Science Illustration, an annual event put on by the Spanish National Museum of Natural Sciences and the Catalan Association of Science Communication. They also featured in a Talk at Google  in 2018, are soon to appear in Fossil News Magazine, and will be released in a book in 2020, along with countless other images that have yet to be released.


Choosing to depict the ammonoids as plausible marine creatures rather than aliens in a textbook, Kate hopes to shine a light on the extinct group of animals that calls to mind the threat of extinction faced by marine invertebrates today.
