Av hans blogg får jag intrycket att han är amerikan, om än med latinskt ursprung.
”Christopher DiPiazza attained his first job at the age of thirteen at a private zoo as a part-time animal keeper. When he went to college, he graduated with a degree in Animal Science from Rutgers University where he did most of his undergraduate lab work and research on extant reptiles. After graduating college...he kept being a zookeeper, this time for two facilities (one private, and one AZA), between which he split his time depending on the day of the week. He has also worked and volunteered at the American Museum of Natural History, in New York, the Mesalands Dinosaur Museum, in New Mexico, and the Academy of Natural Sciences in Pennsylvania. Nowadays he is a science teacher full time, but never truly cut ties with the zoo and paleontology fields. In addition, Chris is a published paleoartist, having illustrated prehistoric life for many scientific papers, posters, books, articles, and museums.”
