Dave Trexler



Dave Trexler has worked in the field of paleontology since the early 1970's. He and his family have been heavily involved in dinosaur nesting behavior research (Dave's mother found the very first baby dinosaurs in a nest in the world!), and Dave has worked throughout western North America. He has worked with the Two Medicine Dinosaur Center since its founding in 1995. Dave is a degreed paleontologist, and his graduate work was a treatise on Maiasaura at the University of Calgary. Dave and his crew collected and prepared what was the only known specimen of a single adult individual of that species, and Dave's work is still a desk reference for anyone working on duckbilled dinosaurs.


While growing up on a ranch in rural Montana, Dave became well-versed in the art of welding and iron work. This ability, coupled with his wealth of knowledge concerning dinosaur anatomy, has allowed Dave to supervise and create some of the finest dinosaur skeleton mounts and displays for a number of museums, including TMDC. This is in addition to his numerous publications on dinosaurs and related topics, his most recent being a general audiences book on climate change from a paleontological perspective.


Dave's love of dinosaurs is matched only by his love of flying, and he has spent many hours mapping possible dinosaur-bearing outcrops from the air!
