380-Million-Year-Old Fossil of a Fish that Gives Birth to Live Young

A 380-million-year-old fish fossil (Materpiscis attenboroughi) was discovered in Australia. It is unique because it was complete with an embryo and intact umbilical cord. This kind of fish gave birth to live young as opposed to fish that release eggs that are then fertilized outside of the body.
