World's ‘oldest 3D heart’ found in prehistoric fish

Australian scientists make "jaw-dropping" discovery that will blow your mind

The lead scientist from Australia, Prof Kate Trinajstic from Curtin University, told BBC News.

Instead of the skeleton, most fossils are made up of the fish's soft tissues. But in Kimberley, where there is a rock formation called Gogo (or Gogango)

minerals have preserved many of the fish's organs including its heart, stomach and intestine.

The discovery of fossils provide a sign of early stage human evolution. Scientists are excited to finally

The discovery of these 100 million-year-old monoliths is jaw-dropping.

Their description has been called "mind-boggling" by John Long from Flinders University in Adelaide.

The apparent age of the soft organs found in these animals is unprecedented.

The human heart evolved in an early ancestor of humans, the Gogo fish. The heart was double-chambered, and it went on to develop into the human heart.
