BANJARMASINPOST.CO.ID – Discovery fish heart 380 million years ago surprised researchers fish heart was found in Fossil ancient vertebrates.
Here’s what it looks like fish heart this ancient.
According to paleontologists, fish heart this ancient found in Fossil 380 million year old armored fish.
This ancient fish extinct by experts called arthrodire evolved for about 50 million years during the Devonian period.

These ancient fish later disappeared during a major global extinction event.
This discovery is also extraordinary. Since soft tissue is rarely found in the fossil record, it tends to decompose before fossilization occurs. Less often is the soft tissue in three dimensions.
So unsurprisingly, the results are good news because when scanning the fossils, it allows scientists to study their anatomy in 3D without the need to break up the precious fossil.
As quoted by Science noticeFriday (9/16/2022) thanks to the extraordinarily fine conservation, details such as atria, ventricles and outlets can be clearly identified in the fossils.
“The really remarkable thing about fish is that their soft tissues are preserved in three dimensions. Most cases of soft tissue conservation are found in flat fossils, where the soft anatomy is nothing more than a stain on the rock.” said Per Ahlberg, a paleontologist from Uppsala University in Sweden.
The researchers are also very fortunate that modern scanning techniques allow them to study soft tissue in fossils fish heart fragile of 380 million years without destroying it. A few decades ago, this would not have been possible.
