Meet Nephila jurassica, a 165-million-year-old spider fossil recently found in China. A relative of the modern golden orb-weaving spider, it’s the largest fossil spider ever found.
And yet it is disappointingly small. The scale bar on the image is 5 millimetres, so the whole specimen is barely 5 centimetres long – though it may have been larger in life, with its legs fully extended. By comparison the biggest living spiders are the Goliath bird-eater (Theraphosa blondi) and the giant huntsman (Heteropoda maxima), both of which have leg spans of 30 cm.
On the face of it that’s surprising, because related creatures like insects were much larger in the past. Around 300 million years ago, oxygen levels were much higher than today. Invertebrates – many of which rely on simple diffusion rather than a circulatory system to delivery oxygen to their tissues – grew to monstrous sizes. Some dragonflies had wingspans of up to a metre, while some millipedes were 2.5 metres long.
All of which suggests that there are some much bigger fossil spiders out there, waiting to be discovered.

It is always nice to see people coming together to help out in a time of despair. Check out how this Design Studio in Phoenix is still making a difference 6,000 miles away from the devastation in Japan…
Design has the power to change the world, and in the wake of the earthquake and tsunami that devastated Japan on March 11, 2011, we wanted to use design to affect meaningful change. That’s why we created this FREE poster to help promote relief assistance. It’s letter-sized for convenient printing. We hope you’ll print one, or 12, and hang them in local coffee shops, yoga studios, or anywhere you think people will see them and be motivated to positive action. Think of it as guerrilla marketing for a good cause. We’re all on this earth together.
