John Woodmorappe refers to Jan Peczkis as a science educator in one of his ‘articles’. He didn’t tell anybody that he referred to himself. Nobody knows what his qualifications are. We just know that he is a ‘science educator’. He certainly is not a geologist. He just calls himself a ‘science educator’.
Jan Peczkis claims to have an MA in Geology from Northeastern Illinois University, and there are two citations on Jstor for someone of that name from the same university, both in the Journal of Vertebrate Paleontology:
Implications of Body-Mass Estimates for Dinosaurs
Jan Peczkis
Journal of Vertebrate Paleontology, Vol. 14, No. 4 (Feb. 15, 1995), pp. 520-533
Trends in the Description of Extinct Genera among Mammalian Orders
Jan Peczkis
Journal of Paleontology, Vol. 63, No. 6 (Nov., 1989), pp. 947-950
