Australian researchers have discovered a 380 ทุนฟรีเล่นสล็อต million-year-old 'heart', the oldest ever discovered. In the jawed fish from the primitive era including the abdomen, intestines, and fossilized liver which provides new information on evolution in biology



Xinhua news agency reported from Sydney. Australia on Sept. 19 that Kate Trinage Stig, a researcher from the field of molecular biology and biology. Curtin University and the Western Australia Museum said the discovery was very special and rare. because it was the discovery of the soft tissues of ancient creatures in a three-dimensional condition.


“As a paleontologist who has studied fossils for over 20 years, I was truly amazed to discover the 380 million-year-old heart of our ancient ancestors in their beautiful three-dimensional state,” Trinagstig said in a statement. The discovery was published. through Science magazine last friday


It is the first time that the intricate S-shaped heart (S) has been discovered from arthrodire, a jawed fish-like creature. and armor from the Devonian era, 419.2-358.9 million years ago, this heart has two chambers and the upper chambers are smaller than the lower chambers.

Trinajstika went on to say that This discovery revealed that The head and neck began to change. How to support the jaw part? This is an important step in the evolution of the human body. And it allows us to see all the organs of the primitive jawed fish that are not different from ours.


The researchers used state-of-the-art technologies such as neutron beams and synchrotron light. Scan specimens still trapped in the limestone. and creates a three-dimensional image of the soft tissue within its body. All fossils were collected from the Kimberley region. of Western Australia
