The discovery took place in the Mahajanga Basin, northwest of Madagascar. However, scientists have issued warnings about this.

A huge and incredible discovery took place in the bottom of the seawhich left hundreds of scientists amazed by what they discovered.

The group of researchers worked in the Mahajanga Basin, northwest of Madagascar, to identify a strange group of sharks and rays that inhabited the place 55 million years ago.

This account usually produces enough fossil remains of terrestrial and marine ecosystems, but it is a totally unknown fauna to this day. Eocene time.

Karen Samonds, of the University of Northern Illinois, worked with colleagues to collect isolated teeth, dental plaques and stingrays from old coastal sediments of Ampazony regions. and Katsepy, located at the bottom of the sea.

They have been identified at least ten species of sharks and raysAmong them, a new species could be interviewed: the 'Carcharhinus underwoodi', which is the oldest identified of 'Carcharhinus', a genus that has been distributed worldwide over the course of 35 million years, but which is rarely known. Eocene

In addition to the new species discovered by this group of researchers who published the study, the Eocene fauna of Madagascar also shares many Eocene ecosystems in North Africa, suggesting that the animals have spread to the southern seas only then.

However, in the study, they warn that the image provided about this new discovery is incomplete, as they only collected fossils larger than 2 millimetersand we recommend looking into even smaller materials in the future to get a more complete picture of the old ecosystem.

In addition, the Malagasy fauna is desperately short of sand sharks and is dominated by eagle rays, indicating a somewhat unusual ecosystem.
