Scientists have found a 12-million-year-old dog fossil in Maryland. The fossil seems to point to a new kind of canine species called "bone crushers."
Contrary to earlier findings, Australopithecus sediba had jaws that could dislocate following a hard bite.
Trap-Jaw ants use their jaws to hunt prey but also used them to escape predators.
