Although it is often impossible to tell which species produced these fascinating petrified feces, it is supposed that the fine examples found in a small area of Washington State are from a Miocene turtle.

What is undeniable is their evocative and varied form, superbly demonstrated in this collection of five different examples, two of finely textured botryoidal form, one in rich rusty red, the other a dark purple-brown, attractively speckled in white; one from a creature apparently in need of a more fibrous diet, of unusually soft definition in warm orange-ochre; and two with deeply cracked surfaces exactly like dried excrement, in green-gray and burnt umber, 4 to 6 inches long.

This truly spectacular specimen is possibly the longest example of coprolite – fossilized dinosaur feces – ever to be offered at auction.

It boasts a wonderfully even, pale brown-yellow coloring and terrifically detailed texture to the heavily botryoidal surface across the whole of its immense length.

The passer of this remarkable object is unknown, but it is nonetheless a highly evocative specimen of unprecedented size

The loving textual consideration applied to dinosaur crap by the copywriter is really something to be truly admired.
