Ancient sea monster had unimpressive brain

A 520-million-year-old sea creature that was one of Earth’s first known predators has been dug up in China. Known as an anomalocaridid, or abnormal shrimp, the well-preserved fossil gives researchers the first glimpse of its brain, which has turned out to be a bit underwhelming. According to The Guardian, its mind was simpler than that of some of its prey and not any more complex than the mind of today’s velvet worms. Because of the find, the paleontologists suggest the creature is a distant relative of the worm, they write this week in Nature.
