It’s of the nonorganic kind, however. Look into the maw!
What a fun museum the Peabody is. It’s definitely old school in that stuff-in-vitrines kind of way, but I can certainly appreciate that. They have a tremendous fossil collection, including plenty of mollusks, but they have a tiny fraction of these things on display. However, I did see a ground sloth skeleton that still had skin and hair on it! And the biggest turtle skeleton of all time! And the model of Arthropleura, the largest terrestrial invertebrate of all time, from those glory days when the earth’s atmosphere had more oxygen and could support such monsters. I’d never heard of it, but evidently the BBC uses exaggerated versions of it in various TV specials.
