A Paleontologist Presents Stygimoloch: LATEST research on NEW fossils of the CONTROVERSIAL dinosaur

Stygimoloch spinifer, the "spiny devil from the River Styx" is a contentious species of dinosaur that some researchers think is the same thing as Pachycephalosaurus wyomingensis. It lived in the final half million years before the doomsday asteroid impact that ended the Cretaceous Period and the Mesozoic Era. In my new, just published paper, I described three new specimens that I referred to S. spinifer and that have implications for paleobiogeography, biostratigraphy, and the veracity of this species. I collected these specimens while doing my Master’s thesis in 1995 and misidentified some of them because little was known about Stygimoloch back then. Then I did my PhD, had a career in the energy industry, and hadn’t looked at them again until last year. Now that I have time (being self employed as a consultant), I’m able to revisit my thesis collection armed with 30 years of new fossil discoveries and acquired knowledge. Best of all, I can finally publish the results of my thesis work and this is the first paper from it! You can get the paper here because it’s open access: https://www.idunn.no/doi/10.18261/let.57.4.7?fbclid=IwY2xjawIOAnRleHRuA2FlbQIxMAABHZjdlzIAHJ3ey6dZPwvnXjmGWTLh2hQ2oSHk0HVBlDjUCsm4vk3AlL3JjA_aem_Cbli6p1voOciRjDWASKy8w and also here: https://www.researchgate.net/publication/388555811_Southernmost_record_of_the_pachycephalosaurine_Stygimoloch_spinifer_and_palaeobiogeography_of_latest_Cretaceous_North_American_dinosaurs
