Scientists Found Another Lung Fish Fossil


Scientists found a fossil lung fish from 372 to 359 million years ago in South Africa. Previously, the fossil lung fish found in Morocco, unlike today’s lung fish, did not live in salt water.

Scientists have discovered another lunged fish fossil dating back millions of years. The fossil lung fish found for the second time added another piece to the puzzle of life forms that began to evolve in water more than 400 million years ago. The new fossil of the lunged fish species (Isitithi mlomomde) was found 10,000 miles south of the first fossil. The fossil found in the Famennian Witoort Formation in the western cape of South Africa surprised scientists because the region was around the pole at that time.

Dr. Flinders University. Alice Clement stated that tooth fragments and scales were found in the fossil remains. Dr. Lung says that the fossil fish is remarkable for several reasons. Clement said that the fossil was the only lunged fossil in the west of Gondwana in the Late Devonian times, where South America and Africa were the only continents. In this period 372 to 359 million years ago, South Africa was located next to the South Pole.

Lung fish are closer to mammals:
Researcher; The fossilized lungs seem to have lived in a thriving ecosystem and show that the region is not as cold as the present polar regions. However, the fish is exposed to long winter darkness, unlike today’s freshwater lunged fish.

There are only six lung fish species known to live in Africa, Australia and South America. The nomenclature Isiyumzi mlomom means ‘long mouthed device for crushing’ in the isiXhosa language spoken in South Africa.

It is estimated that 100 species of primitive lung fish have changed during the Early Devonian period, some 410 million years ago. More than 25 species are thought to exist in Australia, while others live in the mild tropical and sub-tropical waters of China and Morocco.

Lung fish; a species of fish associated with terrestrial vertebrates such as amphibians, reptiles, birds and mammals, and all tetrapods. Dr. Clement points out that lunged fish are closer to mammals than Japanese fish.
