Here’s a fascinating fossil that is one of a kind.
In 2012, researchers found what they say is the only fossil of a spider in the act of attacking its prey caught in its web – a 100 million-year-old snapshot of an engagement frozen in time.
According to researchers, “aside from showing the first and only fossil evidence of a spider attacking prey in its web, the piece of amber also contains the body of a male spider in the same web. This provides the oldest evidence of social behavior in spiders, which still exists in some species but is fairly rare. Most spiders have solitary, often cannibalistic lives, and males will not hesitate to attack immature species in the same web.”
