Permanent exhibition. Opened June 1995. Located on Floor 4, Section 13. One of two halls in the David H. Koch Dinosaur Wing, the Hall of Saurischian Dinosaurs at the American Museum of Natural History displays fossils from one of the two major groups of dinosaurs. Saurischians are characterized by grasping hands, in which the thumb is offset from the other fingers (1). The scientific team of paleontology curators, supervisors, and preparators for the hall installation included Mark Norell, Lowell Dingus, Eugene S. Gaffney, Michael J. Novacek (2, 1995), Jeanne Kelly, Phil Fraley, and Steven Warsavage (3, 1995, p. 6-10).
The Museum reimagined its fossil halls in the 1990s. Chronologically arranged exhibits were updated to reflect evolutionary relationships. The Halls of Saurischian and Ornithischian Dinosaurs, the Lila Acheson Wallace Wing of Mammals and Their Extinct Relatives, which includes the Hall of Primitive Mammals and the Paul and Irma Milstein Hall of Advanced Mammals, the Hall of Vertebrates Origins, and the Miriam and Ira D. Wallach Orientation Center were the result of this rearrangement in exhibition (4, 1994/96 p. 5).
The Hall of Saurishcian Dinosaurs features exhibits such as the iconic and imposing mounts of Tyrannosaurus rex, Apatosaurus, and Allosaurus as well as the Glen Rose Trackway, Deinonychus, Coelophysis, and Velociraptor (1).
Branching off the main evolutionary line are alcoves containing smaller groups of dinosaurs within the saurischian family: theropods, marked by a three-toed foot; tetanurans, which have a three-fingered hand; and finally, coelurosaurs, a group of saurischian dinosaurs with relatively long arms. This group includes maniraptors, whose evolutionary branch extends to birds—the only group of dinosaurs alive today (1).
In a corridor leading to this hall, video footage and archival photographs explore the history of paleontology at the Museum from the first fossil expedition in 1891 to the present day. The hall features a Diplodocus pelvis found in 1897, the first fossil dinosaur specimen collected by Museum researchers as well as models of a preparation lab and a fossil site in Mongolia’s Gobi Desert. Visitors can view a cast of the fossilized remains of a nesting oviraptorid female found in Mongolia in 1994, which confirmed that some dinosaurs incubated their eggs like modern birds (1). In 2007 the new Dinosaurs Halls were renamed as the David H. Koch Dinosaur Wing in honor of Trustee David H. Koch (4, 2007/08, p. 4).
