Barosaurus.




The name "Barosaurus" refers to the size of this dinosaur. It is one of the greatest of all time, similar in size to Diplodocus.

The Barosaurus could reach up to 30 meters long and, at first sight, we would observe that it is the classic sauropod. Elongated, with stretched neck and whiplike tail with a tiny head and resting on its 4 legs. Was proportionally more massive than the Diplodocus, and this one was because its tail but was not as long, compared the neck itself was longer than the diplodocus.


Such a long neck poses many problems, especially uploading blood to the head that rose to the highest eat leaves of the highest trees. To address this, the general opinion raises the option of having a powerful and great heart. It has been estimated that the heart of this prehistoric animal could be as heavy and as big as the heaviest and largest bison: a heart of 1500 kg ...

Another option raises the possibility that something was 8 hearts .... funny because I know, some cephalopods have more than one heart ... but eight?
Another option is posed that Barosaurus veins had valves closed and allowed to recede and the blood does not create pressure which could be fatal. This method prevents the giraffes do not exploit their veins when head down to drink.
Mathematical models have clarified the issue, and have come to the conclusion that the animal raised its head .... then why such a long neck?

Another thing that attracts attention is that its neck vertebrae was huge. Of course, the whole animal was huge, have said the size of heart, but get an idea of ​​what our small neck vertebrae that are ... for those of Barosaurus larger than 1 meter. However, it is thought that these vertebrae were hollow, that it can reduce the weight of the neck.

Vegetarian and small head, this would be a great animal that if we go back 150 million years and travel to Africa, we would see it and we should be amazed that it was so big. We should be amazed that on Earth we know today had ever had a big animal.
