A Strong Heart 380 Million Years Old Found In A Purba Fish Fossil
JAKARTA - The world's oldest heart has been found in an ancient fish fossil dating back 380 million years ago. Researchers discovered fossils in Gogo Formation in the Kimberley region of western Australia, a coral reef that preserves unique fauna and flora from the end of the film.
The body organs appear to be very durable next to the stomach, intestines and hearts of separate fish fossils. Those who discovered this oldest heart fossil, researchers from Curtin University hoped the discovery could explain how creatures, including humans, evolved.
It is claimed that the fossilized fish used to swim in the waters during the badminton period, between 419 million and 359 million last year.
The findings published in the journal Science show the fish came from the ardrodire family, an extinct group of armored fish, but has anatomy similar to modern sharks.
Professor lead researcher Katertijstic finds this extraordinary, as it is very rare to find soft tissue for ancient species that are well preserved.
As a paleontologist who has studied fossils for more than 20 years, I was absolutely amazed to find the 3D heart and beautifully preserved in my 380 million-year-old ancestor, said Professor flowed as quoted by The Independent, Friday, September 16.
Evolution is often considered a series of small steps, but these ancient fossils suggest there is a greater leap between vertebratas without jaw and aca nutmeg. These fish really have a heart in the mouth and below the SSI, like modern sharks," he added.
Using neutron rays and soap opera X-rays, the researchers scanned specimens still embedded in the limestone. It allows them to build 3D images of the soft tissue inside.
The 3D image reveals the fish has a complex S-shaped heart, consisting of two spaces with a smaller than the two sitting on top. Professor spiritjstic stated, this has been developed for an initial vertical.
"For the first time, we were able to see all the organs together in primitive star fish, and we were very surprised to know that they were not so different from us," said Professorplistic.
