Giant Coprolite in Dominican Amber

I have gone through the house on ID'ing this specimen. For the longest time I thought it might be a Nematode, and earthworm, anything! I now feel that this is one of the most unusual coprolites I have ever seen. There are three parts to this. The large part still looks like a worm, but I cannot discern any anatomical features. Earthworms are segmented - this is not. Nematodes have a specific anterior and posterior - this does not. The final guess is a coprolite. I do not have the foggiest idea what animal this is from. Your guess is better than mine.
