中国でジュラ紀のクモの化石が見つかりました。

ScienceShot: Jurassic Spider Not So Itsy Bitsy A new fossil discovered in the Daohugou Beds of northeastern China shows that a modern group of spiders, called golden orb-weavers or Nephila, were on Earth during the Jurassic period about 165 million years ago. The fossil, Nephila jurassica, is a female, and if modern spiders are any guide, was probably much larger than her male counterpart. With a 15-centimeter-plus leg-span, she's the largest fossilized spider ever found, researchers report online today in Biology Letters.

タイトルにあるように、ちっぽけだったわけじゃない、っていうことで。メス、体長15センチメートル。クモ嫌いの人には鳥肌がたちますね。
