Situated in Laurel, Maryland, Dinosaur Park is an out of doors laboratory the place paleontologists, park guests, and the climate mix forces to find a whole lot of fossils.
GLEN CANYON NATIONAL RECREATION AREA, Utah – The Nationwide Park Service introduced Friday {that a} discipline crew found physique fossils, equivalent to bones and enamel, alongside a stretch of Lake Powell in Glen Canyon Nationwide Recreation Space.
