This spider was trapped in tree resin about 20 million years ago. Over time, the resin fossilized to amber, preserving the animal inside. Specimens like this are helpful given that spiders don’t fossilize well in sediment. They offer researchers good information about the group’s more recent history. The oldest known amber specimen is from around 130 million years ago. This specimen was collected in the Dominican Republic.
