Ammonite fossil ! merci @marie.vianssonponte pour ce cadeau. Je l’ai mis sous microscope il y a déjà un moment – ces lignes de suture / croissance sont juste incroyables. #ammonite #fossil #macro #macrophotography By sunchiUncategorizedNo Comments Posted from Instagram March 12, 2023 Love0

I received this ammonite fossil from my friend Marie, (about 2cm in diameter) and when you zoom into it you see these fascinating repeating patterns. “Ammonite shells have complex patterns of “suture lines” that vary across species. The lines are formed at the intersection of the outer shell wall and the septa.” #biology #ammonite #morphogenesis By sunchiUncategorizedNo Comments Posted from Instagram March 4, 2023 Love0
