The oldest heart of the world!

My daughter needed a recent article for school, and found a very interesting one: the mummified droppings of a Hyena were found in the North Sea, some 30000 to 40000years old. So we took out some books about prehistorical life: the world of dinosaurs suddenly appeared in my living room! And so my oldest son suggested to try and find the oldest heart... 


I found it, I think. It belonges to a mummified dinosaur. There are only a few of them, and a fascinating world comes to life.  One of those mummies, 'Willo', actually exposes his heart, which has four chambers and therefore scientists believe that dinosaurs were warm-blooded creatures, close to the birds..

The 7th heart will be the oldest one! Work to do now...
