when did dry tortugas become a national park
Dry Tortugas National Park Comprising 47,125 acres (19,071Â ha), Fort Jefferson National Monument was designated by President Franklin D. Roosevelt under the Antiquities Act on January 4, 1935. The monument was expanded in 1983 and redesignated as Dry Tortugas National Park on October 26, 1992, by an act of Congress.[15][16] Dry Tortugas is managed by the staff of Everglades National Park.[17] The park was established to protect the island and marine ecosystems of the Dry Tortugas, to preserve Fort Jefferson and submerged cultural resources such as shipwrecks, and to allow for public access in a regulated manner.[12]
Triceratops Torosaurus is a ceratopsid genus first identified from a pair of skulls in 1891, two years after the identification of Triceratops. The Torosaurus genus resembles Triceratops in geological age, distribution, anatomy and physical size and it has been recognised as a close relative.[83] Its distinguishing features are an elongated skull and the presence of two fenestrae, or holes, in the frill. Paleontologists investigating dinosaur ontogeny (growth and development of individuals over the life span) in the Hell Creek Formation, Montana, US, have recently presented evidence that the two represent a single genus.
