 I tend to think their diet being more flora and fauna.

As opposed to what else?

Back in 2007 while hiking in the Porcupine Mountains in UP of Michigan I saw a large pile of scat. I just assumed Black Bear. Since then I have seen alot of bear scat on our land, and it did NOT look anything like what I saw in Michigan. It was a large amount, I would guess the pile was the size of a frisbee and it was lighter colored as apposed to brown. It did not have anything in it, like grass or berries or any distiguishable plant matter. I wish I would have taken a picture of it. I have seen many piles of animal scat over the years, and have never seen anything like it since.

Quoting a post from our forum on this topic, this was from an article.

 

"Here's a quote.."The other case of which I have first hand knowledge is a quantity of which was shipped in a plastic container with dry ice to me in New York, for trans-shipment to Professor W. C. Osman Hill, then senior scientist at the London Zoological Society. This specimen shook up the scientist. I wish we had space to give you their report in full. It is quite amazing. The points of significance in it are as follows: In general, this fecal mass did not in any way resemble that of any known North American animal. On the other hand, it did look humanoid, but it had some peculiar features, as if the lower bowel had a spiral twist. But above all, it was composed exclusively of vegetable matter and this as far as could be identified of local California fresh water plants. The real clincher, however was that it contained the eggs and desiccated remains of certain larvae otherwise known only in (a) some North American Indian tribal groups in the Northwest, ( B) pigs imported from south China, © human beings in country districts in southwest China and (d) in pigs in that same area.

Here is a bit on a similar topic of species specific parasites , a  paper in 2004 published on how they came from an archaic hominid species possibly erectus ?

"Parasite genes reveal modern and archaic humans made contact

A University of Utah study showing how lice evolved with the people they infested reveals that a now-extinct species of early human came into direct contact with our species about 25,000 years ago and spread the parasites to our ancestors.

The study found modern humans have two genetically distinct types of head lice. One type is found worldwide and evolved on the ancestors of our species, Homo sapiens. The second type is found only in the Americas, evolved on another early human species (possibly Homo erectus) and jumped to Homo sapiens during fights, sex, sharing of clothes or perhaps cannibalism. "We’ve discovered the ’smoking louse’ that reveals direct contact between two early species of humans," probably in Asia about 25,000 to 30,000 years ago, says study leader Dale Clayton, a professor of biology at the University of Utah. "Kids today have head lice that evolved on two species of cavemen. One species led to us. The other species went extinct."

Alan Rogers, a co-author of the study and professor of anthropology at the University of Utah, says: "The record of our past is written in our parasites."

The analysis of lice genes also confirmed two other key developments in human evolution. First, it verified studies showing how and when various species branched off the family tree of primates and humans. Second, it confirmed the "out of Africa" theory that the population of Homo sapiens mushroomed after a small band of the early humans left Africa sometime between 150,000 and 50,000 years ago.

The study will be published online Oct. 5 in the Public Library of Science journal PLoS Biology. The study’s first author is former University of Utah postdoctoral fellow David L. Reed, now assistant curator of mammals at the University of Florida’s Florida Museum of Natural History. Other authors are Vincent Smith of Scotland’s University of Glasgow, and Shaless Hammond, who worked in Clayton’s lab as a high school student.

Did Modern Humans Date Other Species – or Kill Them?

Transmission of the second type of lice from a now-extinct human species to Homo sapiens may have happened during mating, so Reed plans a study of pubic or crab lice – which only spread sexually – to confirm or disprove that possibility. Clayton and Rogers say it’s also possible our ancestors got the second kind of head lice by fighting with or cannibalizing another human species – or by sharing or stealing their clothing.

Clayton says evidence of contact between two species of humans is surprising because "Homo erectus has long been thought to have gone extinct hundreds of thousands of years ago," although recent studies suggested Homo sapiens might have had contact with Homo erectus in Asia 50,000 years ago.

Reed says: "Not only did modern humans live contemporaneously with close cousins such as Neanderthals, but also with more archaic hominids such as Homo erectus, a species that we have not shared a common ancestor with for over a million years. It is amazing to know that we had physical contact with another species of human. We either battled with them, or lived with them or even mated with them. Regardless, we touched them, and that is pretty dramatic to think about." Reed wonders if contact with our species proved fatal.

"When scientists first determined that we (Homo sapiens) were contemporaneous with Neanderthals (Homo neanderthalensis) in Europe, it was suspicious that our contact with them immediately preceded their extinction," Reed says. "Our study has provided evidence that we had contact with Homo erectus in Asia just prior to the extinction of that species as well. Did we cause the extinction of two other species of humans?"

Findings Show Lice and Different Human Species Evolved Together

Our genes reveal the evolutionary history only of modern humans. Fossil evidence is scant for now-extinct species of early humans. Because lice evolved in concert with the humans they infested, lice "have recorded events in human evolutionary history in their DNA," Reed says.

The researchers analyzed the physical appearance and genetic material (mitochondrial DNA) of modern human head lice, Pediculus humanus, to construct a family tree for lice showing when various species branched off from each other. Genes of modern lice also were used to reconstruct their population histories over time.

The researchers found the family tree of the lice closely mirrors the previously published family tree of humans and their primate ancestors. That was consistent with the well-known phenomenon that any single species or lineage of lice (like other parasites) tends to stick only to one species of host and rarely jumps to other hosts.

Scientists already knew that early ancestors of our species, Homo sapiens, diverged from other archaic humans about 1.2 million years ago. (There is semantic debate over whether those archaic humans should be called Homo erectus, or whether the name should be reserved for their more recent descendants.) The new study showed two almost identical-looking but genetically different strains of head lice diverged 1.18 million years ago. That indicates each of the two kinds of head lice infested a different species of early human as the human species diverged.

Genes from both types of head lice are found on people today, suggesting that after infesting Homo erectus or another archaic human species for 1 million years, the second louse type jumped from that soon-to-be-extinct species and onto Homo sapiens. "In order for the archaic human lice to still exist on modern humans, archaic and modern humans had to coexist in time and space," Clayton says.

What Lice Say About Theories of Human Evolution

Some of the findings conflict with two major theories of human evolution – the "replacement model" and "multiregional model" and instead fit best with a third theory known as the "diffusion wave model."

(1) The replacement model says that after primitive human ancestors first left Africa about 2 million years ago, a second wave spread out from Africa sometime after 150,000 years ago and certainly by 50,000 years ago, and then replaced other now-extinct species of early humans in Africa, Asia and Europe without breeding with them.

Clayton says that model doesn’t fit the louse data because if Homo sapiens from Africa replaced archaic humans elsewhere without interacting with them, the type of lice on archaic humans would have gone extinct with their hosts instead of jumping to modern humans.

(2) The multiregional model says early humans from Africa and elsewhere in the world mated with other each other, so Homo sapiens gradually evolved in many regions worldwide. But if so much interbreeding occurred, the two groups of lice probably would not have remained genetically distinct for the last 1.18 million years, Rogers says.

(3) The diffusion wave model falls between the other two theories. Like the replacement theory, it says modern humans arose in Africa and spread across the world, Rogers says. Like the multiregional theory, it says those early humans mated with humans elsewhere. The diffusion wave theory adds a new twist, namely, that the genes of humans spreading from Africa came to dominate the modern human genetic blueprint because when they mated with archaic humans, the children were less fit.

"As they come out of Africa, they replace other populations while interbreeding with them," Clayton says.

The findings in lice are most consistent with the diffusion wave hypothesis, which allows some interbreeding among various forms of early humans but also says the genes of early humans who left Africa came to dominate Homo sapiens, he adds.

Lice Genes Confirm Key Events in Human Evolution

The new study confirmed several events in primate and human evolution. The researchers found chimp lice and human lice diverged roughly 5.6 million years ago, consistent with previous evidence that chimps and human ancestors diverged from a common ancestor about 5.5 million years ago.

The study also supports the controversial view that there was a "bottleneck" or reduction in the global Homo sapiens population to only about 10,000 people about 100,000 to 50,000 years ago. Rogers and others have proposed the bottleneck may have occurred because of a mass die-off of early humans due to a globally catastrophic volcanic eruption. Others believe the population bottleneck seen in human genes happened because only a small group of human ancestors left Africa in the second wave 150,000 to 50,000 years ago, then reproduced to cause a sudden population expansion.

The new study used the mutation rate in lice and comparisons of genetic differences among lice to find a similar population bottleneck in the group of head lice that infested early Homo sapiens, but no such bottleneck in the population of the lice on the archaic human species. That means archaic humans didn’t go through the same population shrinkage and thus must have spread their lice to Homo sapiens sometime after 50,000 years ago. Rogers speculates contact occurred 25,000 or 30,000 years ago. "

Its the discovery of unknown species of primate type parasites in scat that helps alot  IMO

I read a witness report years ago that described a bf defecting while standing in a river. I this is common, it would be one way of hiding spoor, but also contaminate the water.

I have seen many different piles of scat and one thing I did not see mentioned in the above links is that animal scat may change characteristics based on the season and this is associated with its diet. In the early springtime, the bear scat I usually find is a very dark black color and kind of slimy (kind of like a black tar) consistency.

Prior to my interest in bf, I found one unusual scat pile that was about a total of 10in diameter and about 2in tubular. It was left right in the middle of an old logging road and quite fresh at the time. The only animal that I could think of leaving this was a very large wolf and of course I never took a picture of it.

If anyone one of you do come across an unusual scat pile, scout around the area and see if there are more piles as some animals will use the same are over and over for a period of time.

I have also heard about the BF possibly doing it in water which would explain alot of the stealth of not finding too many droppings and also while Coors isnt that great..  I read somehwere of some people getting sick from some water in a park or lake with a creek draining in or somesuch and a odd species perhaps undescribed pathogenic bacteria from a human or primate was found as a cause? Wish I could recall where I read this.

Case closed Gearman!  What Park is that sign in?

It was Parked on my Facebook Timline posted by a friend.. (entertainment only) LOL

Lots seem to have this idea that they hunt down deer. I for one don't buy that as much. all though such a big animal requires a load of protein so eh who knows??

 They certainly do go for deer { at least in Michigan } in one way or another.

Aqua dump!!!! I have a friend who if famous for this every time we go swimming....needless to say he isn't invited anymore

I've seen the account of the female bigfoot standing on a rock in a river and "letting fly".

 

The scat I've seen was always placed to be found.  It was a clear message that my presence was unappreciated in each case.  It looked human, smelled like the result of a red meat diet, and was very over-sized. 

 

I'm just glad they're not in the habit of throwing it.
