Of all the traditional cauldrons ( ding) since the Shang Dynasty, only rectangular cauldrons, such as the famous Simuwu tetrapod of the Shang Dynasty, have flat bottoms. 商朝以来传统鼎的形制中,只有方鼎为平底,如商代著名的司母戊大方鼎。
These discoveries have expanded almost exponentially our understanding of this critical chapter in the history of life on earth-and turned old notions about early tetrapod evolution, diversity, biogeography and paleoecology on their heads. 这些发现让我们对地球生命史上重要章节的了解,几乎有了巨幅的成长,也因而改写了我们过去对于早期四足动物演化、样性、物地理学及古生物学的观念。
