化石拍賣 （專家強推）

Chimerarachne 是一属已灭绝的蛛形动物，有时被认为就是蜘蛛，包含唯一种 Chimerarachne yingi。Chimerarachne 的化石是在缅甸的琥珀中发现，该琥珀属于中晚白垩纪，大约一亿年前。这些化石在两点关键特征上与蜘蛛相似：用于吐丝的喷丝腺，以及附肢上的改良雄性生殖器用于传递精子。与此同时它们保留了鞭状尾巴，颇似鞭蛛与乌拉兰尼亚类的尾部。Chimerarachne 不是蜘蛛的祖先，它比已知最早的蜘蛛（来自石炭纪）的年龄要年轻得多，但它似乎是一个已灭绝群体的晚期幸存者，该群体很可能接近蜘蛛的起源。这表明曾经存在与真正蜘蛛并存、有尾巴的蜘蛛样动物，至少在两亿年间与真正蜘蛛共存。地点：缅甸 呼卡温谷。大小：琥珀尺寸 35×23×9 毫米

Chimerarachne is a genus of extinct arachnids, sometimes considered as spider itself, containing a single species Chimerarachne yingi. Fossils of Chimerarachne were discovered in Burmese amber from Myanmar which dates to the mid-Cretaceous, about 100 million years ago. These fossils resemble spiders in having two of their key defining features: spinnerets for spinning silk, and a modified male organ on the pedipalp for transferring sperm. At the same time they retain a whip-like tail, rather like that of a whip scorpion and uraraneids. Chimerarachne is not ancestral to spiders, being much younger than the oldest spiders which are known from the Carboniferous, but it appears to be a late survivor of an extinct group which was probably very close to the origins of spiders. It suggests that there used to be spider-like animals with tails which lived alongside true spiders for at least 200 million years.
