The Two Medicine Dinosaur Center is a 501(c)(3) non-profit and educational institute located in Bynum, Montana that opened in 1995. It is part of the Montana Dinosaur Trail and home to a skeletal model of what is believed to be the world's largest dinosaur, a seismosaurus. The Center also houses the first baby dinosaur bones collected in North America - the original discovery reported by paleontologist John R. Horner.[2]
