Returning from the first paleontological expedition "in search of dinosaurs," you realize the amount of things you learn in the days elapsed between the sand, hot sun and sweat ...
I ask you a question: for example, if you were on the field, managed to find fossils of dinosaur bones in the middle of rocks and dust?
Here's a video that can explain one of the most important secrets of vertebrate paleontology ...
bone attaches itself to the language, why?
bone of a vertebrate is composed of organic materials (eg proteins) and crystals produced by the body that give bone its hardness and compactness are all aware. As the bone is alive, grows and changes during the life of the organism, and for this reason it is crossed by blood vessels that have a role to allow the blood to supply the tissues of oxygen and substances needed for life cells. These channels, dug into the hard part of the bone remain even after the fossilization occurred, and precisely because of "porosity" that the bone adheres to our language in this way.
thank Fabio Manucci for shooting video and Philip Bertozzi, Marco Petruzzelli, Marco Castiello, Matteo Fabbri for the applause ...
