Jackson-area resident Sarah Harrison MacMillan was having fun with a floating journey on the South Fork of the Shoshone River with family and friends Saturday when she noticed what she thought was a useless cat floating within the water.
Their boat was anchored, and the carcass drifted shut sufficient for her to seize it by the tail.
It wasn’t a cat, and as of Monday, MacMillan stays stumped with out a optimistic identification about what the thriller critter was.
Marmot, Marten Or Wolverine?
She posted pictures of her holding the unidentified animal on social media, which prompted all kinds of guesses. Some insist that it’s a useless pine marten or maybe a fisher cat, that are members of the weasel household.
Others mentioned it is perhaps an oddly-colored squirrel.
One of many wilder recommendations was that it is perhaps a drowned child wolverine.
MacMillan instructed Cowboy State Day by day that her finest guess is that it was an immature marmot that obtained too near the river, fell in and met its destiny.
Cowboy State Day by day despatched pictures of the thriller carcass to the Wyoming Sport and Fish Division asking for a doable ID, however there was no response from the company Monday.
MacMillian mentioned a have a look at the critter’s enamel probably would have definitively instructed the story of what it was.
Sadly, she by no means obtained the prospect.
She hadn’t been holding it very lengthy when pores and skin on the a part of the tail she had gripped in her fingertips “gloved off” (sluffed off the animal), and the carcass plopped again into the water. She wasn’t capable of seize it once more.
“I’m so intrigued by it,” she mentioned. “I actually love nature and I really like figuring out in regards to the animals.”

Why She Thinks It’s A Marmot
The animal’s fur was darkish, virtually black, she mentioned.
Within the pictures, it additionally seems to have white spots on it. MacMillan mentioned the animal’s eyes had turned white from the carcass being within the water.
Based mostly on her transient examination, she mentioned the opposite white spots seemed to be from the pure decomposition course of. She additionally didn’t see any proof that fish or birds had been making an attempt to feed on the carcass.
She leans towards considering the animal was a marmot due to its toes.
Trying on the pictures, “I can see solely 4 toes within the entrance, with two pads behind. On the rear toes I see 5,” she mentioned.
That matches a marmot’s foot sample.
The comparatively flat cranium additionally signifies a marmot, fairly than an otter or member of the weasel household, she added.
The Tooth Would Have Given It Away
She’s annoyed that the carcass slipped from her fingers and was misplaced earlier than she obtained an opportunity to get a very good have a look at the mouth.
Outsized entrance incisors, widespread amongst rodents, would have been a useless giveaway for a marmot, MacMillian mentioned.
But when the critter had sharp canines and an array of enamel extra suited towards a carnivorous predator, that may have pushed issues extra within the course of a fisher cat or another weasel.
MacMillan mentioned she hopes someone can assist her positively determine the thriller creature.
“I’m barely baffled by it,” she mentioned. “I really feel like I ought to ship the pictures to a biologist.”
