How To Make Aluminum Boat

...... Postcards





On November 30, passed away suddenly my dad. I would have much to say about what has happened, many things but also many sad things serene. But are things to talk eye to eye, the web is not involved.
thank you all for your good wishes and I apologize for being gone from the web.

There are moments to live in silence, moments that you do not have to ride over but where you have to dive without fear. This time has come for us. From here we depart for other chapters and other eras, with the wealth of passato che ti fa da barra d'equilibrio.
Un abbraccio forte
Benvenuta

Panderichthys


Il Panderichthys rhombolepis è un vertebrato estinto vissuto nel Devoniano, circa 380 milioni di anni fa.

I fossili sono stati ritrovati in Lettonia. Lungo dai 90 cm a 1,3 m , questo animale è considerato una forma transizionale tra i pesci e i primi tetrapodi.

Caratteristica più notevole di Panderichthys era la presenza di uno spiracolo a mo' di tubo, utilizzato per il passaggio dell'acqua nella cavità branchiale.Esso sfociava in cima alla testa e con l 'evoluzione darà origine alla staffa, uno dei tre ossicini che compongono the human ear.

Recent studies have examined the fins and found the presence of a humerus, an ulna, a radio and precursor elements of the fingers. That is the evolution of the fingers would move about 5 million years, as suggested by the team at the University of Uppsala, in an article in the journal Nature.
