"A fecal blast, exciting news for coprolitophiliacs, and manure as high as a cow's eye."
==================================


A team of Canadian and American scientists recently identified an Albertan fossil as the world's largest dinosaur dropping, stealing the title from a T. rex turd found in Saskatchewan in 1995.

While stool size is notable, what's really exciting scientists about this latest find is what it contains: Incredibly well-preserved dinosaur muscle tissue.

The 75-million-year-old fossilized feces, formally known as a coprolite, was discovered in the late 1990s near the town of Onefour in southeastern Alberta by Wendy Sloboda, a freelance paleontologist who is currently leading a paleo-tourism tour in the Gobi Desert.

Measuring in at 64 centimetres in length (slightly narrower than the width of the average kitchen stove) and up to 17 centimetres wide, the six-litre bulk of the Albertan coprolite rules out small dinosaurs from contention as the probable pooper, says Ms. Chin, who led the analysis of the specimen. And given the presence of bone fragments, and its age, Ms. Chin and her colleagues think the dropper was probably one of T-rex's earlier relatives in the Tyrannosaurid family, including either Daspletosaurus or Gorgosaurus.
