Beautiful huge ammonite, 28,5kg. Specimen from masagascar. A natural white fossilized enamel and perfect spiral shape making this fossil even more rare and valuable. Truly a beautiful, wonderfully preserved specimen.
Perisphinctes is an extinct cephalopod mollusc belonging to the ammonites. It lived in the Upper Jurassic (172-149 million years ago), and its fossil remains are found on all continents.
Si tratta di animali di ambiente marino, caratterizzati da una conchiglia esterna composta prevalentemente di carbonato di calcio, sotto forma di aragonite, e in parte di una sostanza organica di natura proteica (conchiolina). La conchiglia era suddivisa internamente da setti in diverse camere, di cui il mollusco occupava solo l'ultima (camera d'abitazione). Le altre, che componevano il fragmocono (parte concamerata della conchiglia), erano utilizzate come "camere d'aria" (analogamente all'attuale Nautilus), riempite di gas e liquido camerale per controllare il galleggiamento dell'organismo. La pressione dei fluidi camerali era controllata da una sottile struttura organica tubolare riccamente vascolarizzata, in parte mineralizzata (il sifone), che attraversava tutti i setti e permetteva lo scambio di fluidi dal sangue e dai tessuti molli dell'animale alle camere tramite un processo di osmosi.
