It was Archaeopteryx, discovered in 1861, from the Solnhofen limestone in Germany, which dates back to the Jurassic Period.

它就是始祖鸟， 于 1861 年在德国的 Solnhofen 石灰岩中发现，其历史可以追溯到侏罗纪时期。

Now probably one of the most famous fine-grained sediments of all is the Solnhofen limestone and this was deposited in Germany back in the Jurassic time period.

现在，最著名的细粒沉积物之一可能是索伦霍芬石灰岩，这是在侏罗纪时期在德国沉积的。

And 13 Archaeopteryx specimens have come out of the Solnhofen limestone of which probably the most beautiful, and I think probably the most beautiful fossil ever, is this one here which is the Berlin specimen.

索尔恩霍芬石灰岩中出土了 13 个始祖鸟标本，其中可能是最美丽的，而且我认为可能是有史以来最美丽的化石，就是这里的柏林标本。
