【正文】 ch we can see how ancient Shu people were carrying out their sacrificial activities with ivories。 in addition, it acts as an persuadable evidence to explain why so many ivories were found in Jinsha Site and San Xing Dui Site. Pit 1 unearthed right here (showing where the ivory pit is) is the sacrifice site with best design and pattern and most concentrated burying of cultural relics among all other sacrifice heritages fund in Jinsha Site. Sacrificial articles are also laid in layers. The lower layer deposited jade wares and bronze wares mostly. Due to the bottom unexcavated, the quantity of buried jade and bronze wares is still unknown. The upper layer buried only ivories. Observing the sectional plane, there are altogether 8 layers of piled ivories, and the longest one is up to nearly . The displacement is found in good pattern presenting a magnificent and holy atmosphere. A large number of ivories are unearthed in the Sacrifice Area. Through scientific research, ivories family and species e from Asian Elephant. These ivories are most important offerings to heaven and earth gods contributed by ancient Shu people. However, how many elephants and in what way to be presented to god are differed in each sacrificial activity. We may have this question, there are so many ivories used in their sacrificial activities, where did the elephants e from? Were there wild elephants living in Chengdu Plan thousands of years ago? Early when 81 ivories were unearthed in San Xing Dui Site, archaeologists started their research and guess about the origin of sacrificial elephants. At that time, experts seem agreed on the theory of elephant ing from outside. People believed those elephants came from China Yunnan Province or from India. When so many ivories were presented to the eye of archaeologists and experts this time in Jinsha Site, they were puzzled again about the origin of those elephants. Quite differently from San Xing Dui research, this time, the theory of elephants ing from local is superior over theory of elephants ing from outside. Obviously, there is no any wild elephant living in Chengdu area and even in the whole land of Sichuan Province nowadays. If this point of view that ancient elephants were ing from local is positive, it may imply there is a great difference in weather in Chengdu Plain 3000 years ago vs. the present. According to scientific research, 3000 years ago was globalscale thermomer period with average temperature 2~3℃higher than today. Sourced from literature records, wild elephants, at that time, were found living in the Changjiang River reaches and the middle and lower reach of the Yellow River. Wild elephant is mentioned in Oracle Inscription shown on tortoiseshells or animal bones of Shan Dynasty saying that King of Shang was hunting wild elephants and soldiers were riding elephant fighting in battlefields in China central plains. Shan Hai Jing (Legends of Mountains and Seas) Zong Ci Jiu Jing notes “in the Minshan Mountain…… animal species most are rhinoceros and elephant and Kui cattle Hua Yang Guo Zhi (History of Hua Yang State) Shu Zhi (History of Shu State) also records “this land is called “Tian Fu” (land of abundance), original name was Hua Yang……in terms of treasures in this land, Bi Jade is one of them……also, rhinoceros and elephants are found living in this land…….”. We also found a poem line in Shu Du Fu (Ode of Shu Capital) written by famous litterateur Zuo Si in the Western Han Dynasty singing: “jade green peacocks are flying in the sky, giant rhinoceros and elephants are racing on the ground”. Archaeological researchers found and collected some precious ebony wood in the ancient riverway running through this site (showing where it is), besides, old tree root of large volume also was found. In addition to those findings, elephant cheek tooth, muntjac bone, and tooth of rhinoceros, badger, black bear, cattle and horse, and two well reserved elephant mandibles also were unearthed. All these abundant evidences present us a vivid picture that Chengdu Plain in Jinsha Time was a green land with density and tall forest, where clustered and species varied animals were peting for their survivals. Therefore, we are more confident to draw this conclusion that such kind of ecoenvironment shall be adequate for the living of wild elephant. There is great possibility those ivories unearthed in Jinsha Site are originated from the local place. Conservation of ivory still is a global problem even in nowadays. Looking into the reason, it is because that unearthed ivory for archaeological study purpose is limited in quantity, which results in shallow study on ivory protection methods. So far, there is no any successful case worldwide in protecting ivory. Another reason is the ivory structure itself, which is posed layer by layer same as tree wood year circles. Once the ivory material on the top surface is damaged, it will quickly be weathered away and turned to be powder, which no longer can be rooted to the mother material, leaving null protection. When ivory was found in Jinsha Site, cultural relics conservation experts began to look for effective protection method. At the present, local backfill upon discovery and organosilicon sealing are two methods used in ivory protection in Jinsha Site. A large number of bronze wares were also unearthed in this place. Though majority of them are small sized articles, there is nearly no difference in varieties and design pared with that unearthed in San Xing Dui. The discovery of accessory parts to large sized articles implies the existence of big bronze wares in Jinsha Site. Here is a special deposit spot (bucktooth deposit spot) as we can see, which covers an area of about 300 m2. The burying right here are wild boar bucktooth, deer horn and muntjac horn, which are huge in quantity. Also small number of ivory, jade ware, beauty stone and well reserved pottery ware were unearthed in this spot. Through counting, wild
