I found this turtle shell in Prospect Park. I think it was a red-eared slider. 7.5 inches long. Cleaned it up with hydrogen peroxide and an old toothbrush. Dorsal view, the carapace.
Ventral view, the plastron.
Through-view, the cathedral (my term).
"I celebrate myself, and sing myself,/And what I assume you shall assume,/For every atom belonging to me as good belongs to you.//I loafe and invite my soul,/I lean and loafe at my ease observing a spear of summer grass."
