In 2004, a team of researchers from University of Ohio digging around a cliff Mutca River, in Tanzania, when bones began to appear from what looked like titanose with a long neckHe was not the first to be in this field, so it was a possible option. And so it was, even though the spear whose partial skeleton was a set Credible rocks (100 million years ago), there was a peculiarity that made it different: the bones of his tail, heart-shaped,
This little feature does not seem accidental that the study is published at the end PLOS ONE only the previous day St. ValentineBut this is not the only peculiarity that surroundsMnyamawamtuka moyowamkia (meaning "Mtuka with a heart-tail" of Swahili) as it provides very important information about the history of African fauna.
Another part of the history of the African continent
Excavations that started in 2004she continued four years, during which several groups of pendulists, some of them, were needed climbersBone needs to be carefully removed as it can be destroyed during the wet seasons that have intensively affected this area Tear system, in East Africa.
But it was worth it because the information obtained from these fossils could help restore it Paleogeographic history of the continentIn particular, this underlines this Mnyamawamtuka moyowamkia It is very similar to other titanoses in the same region, but there are some interesting similarities Malawisaurus, an animal whose remains were found throughout Tanzania borders with Malawi,
It also provides new information on the complexity of dinosaurs, as titanos are much more common in South America, but thanks to this team of scientists as well as other groups of researchers, several specimens were found in some areas of the African continent, especially in Tanzania and Egypt,
On the other hand, this team has not excavated only dinosaurs in Africa. Indeed, in recent years they have discovered other interesting fossils, such as mammalian-linked crocodilea set of termites that would support early evidence insect culture and some bones corresponding to the moment in which the primates began to lose their tail,
But this week came to show on dinosaur on the tail of the heartanother part of the puzzle of the African fauna, corresponding to a very special moment, of evolutionary changes. A good way to celebrate Valentine's Day.
