1936年,我国考古学家贾兰坡在北京周口店地区H天内连续发现三个“北京人”的头盖骨、一个下额骨和三枚牙齿,成为20世纪人类最伟大的发现之一.可惜,这些珍贵的文物在装箱运往美国的途中遗失了.几十年来,科学家们为寻找这些文物绞尽脑汁。本文由贾兰坡口述,重现当年他和他的同事们发现这些文物及文物遗失的全过程,记录了贾先生一生的经历及目前的心声,并报道寻找这批文物的新线索。也许,找到这批文物的日子已经临近. In 1936, one of the greatest discoveries of mankind in the 20th century was made by our Chinese archaeologist Jia Lanpo, who successively discovered three skulls of the Pekingese, one of the lower brow and three teeth, within H days of the Zhoukoudian area in Beijing. Precious artifacts were lost on their way to the United States for packing, and scientists have racked their brains for these artifacts for decades. This article is written by Jalalan and recapitulates the whole process of the loss of these cultural relics and cultural relics discovered by him and his colleagues in the same year. It records his life experiences and his current thoughts, and reports on new clues for finding these cultural relics. Perhaps, the time to find these artifacts is approaching.
