The first was found almost a complete skeleton gondwanatheria – mammaliaform from the group whose remains still was represented by a single skull and a few teeth. Paleontologists have discovered the remains of an animal in Madagascar.

According to the journal Nature, he was given the Latin name Adalatherium hui meaning in translation "the mad beast Hu Aamina". It is the most valuable discovery of Mesozoic mammaliaform.

From gondwanatheria long been only teeth, in the form which they have in common with the extinct mammals of multituberculate. Six years ago, Madagascar was able to detect their skull. The animal, which he belonged, called Vintana.

The study of the Maastricht sediment layer, whose age of 72.1 to 66 million years in North-West Madagascar continued, and scientists from the US, Madagascar and China under the leadership of David Krause in the end is lucky they have unearthed a nearly complete skeleton of an animal with an unusual surface, the first teeth located on the upper jaw behind the canines. For this particular discovery attributed to gondwanatheria.

The animal was allocated in a new family Adalatheriidae, calling Adalatherium hui, which means "wild animal Hu Aamina" in memory of the outstanding Chinese paleontologist Hu Aamina.

Researchers estimate it weighed just over three pounds, but at the time of death was not yet sexually Mature, thus, adult individuals of this species were larger.

The researchers hope that the found remains will help to understand how the isolation of Madagascar influenced his Mesozoic mammaliaform.
