Collections
The Dinosaur Institute of the Natural History Museum of Los Angeles County houses a world-class collection of Mesozoic tetrapods (vertebrate animals with four limbs). This collection includes fine fossil specimens of dinosaurs (including birds), pterosaurs, crocodiles, turtles, mammals, and extinct marine reptiles. Some of these specimens are prominently displayed in the Museum's exhibit halls. Other specimens are also available to researchers in the Institute's research facilities. In addition to skeletal specimens, the Institute also houses such rare fossil material as skin impressions and eggs. Among the Institute's unique treasures are a number of holotypes–specimens upon which a new species has been founded–as well as one of the few growth series of Tyrannosaurus rex, a series of fossils ranging from juveniles through adults.
