Still Waters Posted August 17, 2017 #1 Share Posted August 17, 2017 A new study from ANU on a 400 million year old fish fossil has found a jaw structure that is part of the evolutionary lineage linked to humans. The fossil comes from ancient limestones around Lake Burrinjuck, 50 kilometres northwest of Canberra. The area is rich in fossil shells and corals, but also home to the rare skulls of extinct armoured fish called placoderms. "The fossil reveals, in intricate detail, the jaw structure of this ancient fish, which is part of the evolutionary lineage that ultimately led to humans," said Ms Hu from the ANU Research School of Earth Sciences. "The jaw joint in this ancient fish is still in the human skull, but is now part of the middle ear." https://phys.org/news/2017-08-million-year-old-fish-fossil-reveals-jaw.html 2 Link to comment Share on other sites More sharing options...
