海绵可能是最早的分支动物,它们的化石记录可以追溯到前寒武纪。因此,确定它们的骨骼结构和组成是提高我们对后生动物早期进化的理解的关键一步。在这里,我们提出了5.05亿年前的甲壳素的发现,发现在保存异常完好的Vauxia gracilenta海绵从中寒武纪伯吉斯页岩。我们的新发现表明,在适当的结晶条件下,甲壳素的稳定时间比以前怀疑的要长得多。这些化石中几丁质的保存为研究其他古代化石群开辟了新的途径。
Sponges are probably the earliest branching animals, and their fossil record dates back to the Precambrian. Identifying their skeletal structure and composition is thus a crucial step in improving our understanding of the early evolution of metazoans. Here, we present the discovery of 505–million-year-old chitin, found in exceptionally well preserved Vauxia gracilenta sponges from the Middle Cambrian Burgess Shale. Our new findings indicate that, given the right fossilization conditions, chitin is stable for much longer than previously suspected. The preservation of chitin in these fossils opens new avenues for research into other ancient fossil groups.
