Life phenomenon existed and developed  in Gansu for nearly 2 billion years. In the long time, the  landscape and climate changed making all living things experienced the evolution  of natural selection in the survival struggle thus formed a colorful  biodiversity in nature today, ancient fossils are witnesses of these changes.  Gansu province locates in a joining area  among the Mongolia-Xinjiang Plateau, the Qinghai-Tibet Plateau and the Loess  Plateau. Its unique geographical location and changeful climate indicate varied  and complicated environment through geological time. Fossils are the evidences  of these changes. Abundant and numerous varieties of fossils were found in Gansu  province in the past several decades, some of which occupy a decisive position  in China even in the world such as the most completely preserved Stegodon  huanghoensis namely ancient Huanghe Elephant in the world today, Hipparion sp.  fauna found in Linxia Hui Autonomous Region which is the biggest one among all  late Cenozoic fossils mammal  faunas ever found in Eurasian continent,  Giant-tooth lanzhou dinosaur which is the phytophagy dinosaur with  biggest  teeth in the world and Gansus Yumenensis which is the earlist example of   Mesozoic fossil bird in China. Several thousand pieces of paleontological fossil  including 400 pieces of first grade under national protection and 10  restored  skeletons of fossil animals preserved in Gansu Provincial Museum provide rich  resource for preparation of related exhibition.

This exhibition—Paleontological  Fossil of Gansu shows mainly  paleontological fossils of various geological  periods found in Gansu such as fossil fungus and fossil algae of Archaeozoic Era  and fossil mammal of Cenozoic Era, also precious fossils collected from other  provinces in China in order to emphasize the intellectual and systematic feature  of science popularization.

Exhibits of this exhibition are  arranged in three exhibiting halls: marine animals hall, dinosaur hall and  Ancient Huanghe Elephant hall according to the sequence of geological time.  Marine animals hall shows various Paleozoic fossils marine invertebrates,   dinosaur hall shows Mesozoic fossil dinosaurs, fossil fish, fossil plants,  fossil insects, etc. and Ancient Huanghe Elephant hall  shows various Cenozoic  fossil mammals which is the essence of this exhibition. Abundant fossil  specimens and animal skeletons reveal the large quantity and variety of fossil  specimen of this period found in Gansu.

In addition, earth hall is arranged  at the beginning of this exhibition to show appearance and development of life  on earth by means of picture, form, large-scale landscape corresponding to five  geological eras and simulating-space circular dome.

The interaction section at the end of  this exhibition allows visitors to participate in the exhibition-related  activities such as mechanical dinosaur, dinosaur laying egg, having a race with  dinosaur and comparing your own weight to that of  dinosaur.  Screen-touch  multimedia  facilities in the exhibition halls with detailed background  knowledge on exhibits of this exhibition, single-touch phantom imaging facility   in marine animals hall, on-screen assembled puzzle game in dinosaur hall attract  more visitors to the museum.

Through the above-mentioned exhibits,  auxiliary exhibits and various forms of activities, visitors can get a general  clue on paleontological fossil of Gansu, further more,  on earth and  biodiversity on the earth, hence strenghen their concept of cherishing life and  protecting the earth of our common homeland. Both traditional way of expression  and modern acoustic, optical and electrical techniques have been applied in this  exhibition. 

All the facilities used in  exhibition-related activities are mature, reasonable in price, convenient to  maintain; showcases in this exhibition are different from that in cultural  relics exhibition including half-suspended showcase, open-type showcase,  showcase with magnifying glass and inlay-type showcase. The arrangement of these  showcases and combination of various colors are made taking visitors` normal and  special need, visiting convenience as the priority. Sky blue color used in earth  hall indicates universe and ocean,  dark blue color  in marine animal hall  obviously refers to ocean, dark red and yellow color in dinosaur hall refers to  the color of the Mesozoic stratum containing fossil dinosaur, earthly yellow  color in Ancient Huanghe Elephant hall refers to the major color of the stratum  containing fossil mammal. Circular line, semicircular line, arc line, ablique  line rather than straight line in this exhibition, changing of the exhibiting  route and different types of showcase are used in order to add more  interestingness to the visit.Life phenomenon existed and  developed in Gansu  for nearly 2 billion years.
