Représentation d'archosaurien triasique

Some remains of the prehistoric Triassic archosaur found

The Archaeological excavations carried out all over the globe allow scientists to make many discoveries. Even better, they can complement information available on previous research. This is how recently a small team of archaeologists unearthed the remains of what appears to be the remains of the pseudosuchian archosaur Mambawakale ruhuhu.

In reality, it would be a giant reptile that would have lived during the period of the Middle Triassic, present-day Tanzania, would be 240 million years ago. According to the measurements taken, the animal would be about 5 m long. However, a comparison made with remains found in southern Tanzania in 1963 suggests that there are several types of Mambawakale ruhuhu.

The brilliant research team behind this impressive find counts among its members Professor Richard Butler from the University of Birmingham. In addition, the research results were published in the journal Royal Society Open Science.

Reconstruction of the reptile’s profile

Indeed, the Mambawakale ruhuhu would have lived in what would today be the Tanzania during the Middle Triassic period, there would be approximately 240 million years old.

“It would have been a large and terrifying predator, which roamed Tanzania around 240 million years ago. »

In addition, according to the measurements carried out, this giant reptile would make approximately 5m (16.4ft) long. It therefore represents one of the greatest predators known from this period.

Separately, fossilized remains of the animal, including a skull, lower jaw, vertebrae, and a hand, were collected from the Manda beds in southern Tanzania in 1963. From these, Professor Butler and his colleagues were able to identify several characteristics that distinguish the Mambawakale ruhuhu from other archosaurs found in Manda beds.

These finds would consist of a big skulla narrow lower jaw and a variation in the size of the teeth at the front of the upper jaws.

More distinctive signs

“Mambawakale ruhuhu is characterized by several cranial autapomorphies that allow it to be confidently distinguished from all other archosaurs at Manda Beds, with the possible exception of Stagonosuchus nyassicus for which comparisons are very limited due to overlap very limited material. »

However, phylogenetic analysis suggests that the Mambawakale ruhuhu is a pseudosuchian diverging early. Although, a more precise resolution is hampered by missing data. Additionally, the species is also one of the largest pseudosuchians known and recovered to date from the Middle Triassic.
