I passed one of those after my gastric bypass. Mine had two “eyes”, though.

Take it to the botany department at Emory University. I’m really curious as to what it could possibly be.

It looks like it might be Daldinia concentrica, a fungus. Take a look: http://en.wikipedia.org/wiki/Daldinia_concentrica http://www.fichasmicologicas.com/?micos=1&alf=D&art=50 Genus and species Daldinia concentrica Species Code No. A / 2 – Azt 03.14.00.03 Family XYLARIACEAE Subclass ASCOMYCETES Order XYLARIALES Class ASCOMYCETES Synonyms Popular Names KIMO MAMIZEBRATU Practical Importance / Culinary Interests EDIBLE DOUBTFUL, POSSIBLE TOXICITY Macroscopic Description Carpophore of 2 to 6, globular, circular or oval-shaped, rounded and sometimes lobed pad. No foot is adhered directly to the substrate. Hard surface, matte, densely granular, powdered with gray and reddish brown to blackish young, and finally coal black, which seems to cut charcoal. Gleba composed of a hard, porous, light and leathery frame, consisting of black and white concentric layers alternatively, starting from the center, are distributed in a fan shape. Confusions The D. VERNICOSA has a well developed foot and shorter spores. Habitat Saprophyte. In moist forests, on trunks, fallen branches or weakened trees of various genres: Alnus, Betula, Fagus, Eucalyptus, etc.. Season Winter and the rest of the year. Rare species Kitchen Leathery, not suitable for cooking. Good tinder to start a fire, especially blacks and dried specimens, burn like coal Imagery

If this isn’t a college student prank or a misbegotten art attempt, I would start packing!

To me, and I’m guessing, but it looks as though it may be the dried terd of a large dog or animal. I have a 112 pound yellow lab, Barney. I have picked up enough of his “passings” to know that his, while shorter and much much larger in diameter would equal the smaller and much longer diameter of this mass. The color, tubular compression rings, and the length, seem to indicate that this critter hadn’t “gone” in quite a while; defecating may not have been a pleasant experience. The “bit woody like inside” seems typical of Barney’s donations that have aged or cured for some time, while not being exposed to rain and the elements. I have no explanation for the yellowish spots on this mass. If not something that was eaten, maybe it is light reflection, although I doubt that. If this appeared to be growing out of the floor, possibly it had become stuck to the floor when or after being deposited. That happens to Barney’s deposits on our wood deck, concrete driveway, or other surfaces when remaining unnoticed for a while.

It looks a bit like Trichglossom Hirsutum, http://www.messiah.edu/Oakes/fungi_on_wood/club%20and%20coral/species%20pages/Trichoglossum%20hirsutum.htm. Or at least something related.

coprolith

Haven’t a clue but I’d put gloves on when handling it!

Holy Doodle!!! That’s just about the creepiest thing I’ve ever seen (except for my ex’s new wife). It looks like a petrified slug. UGH!!

Looks like a large intestine that has been petrified.

#1 Turd coming out of your malfunctioning sump pump Solution: buy better quality pump and seal top better. #2 Saw a very similar creature in Alien Takeover(same glowing eyes). This is the pod that the aliens morph into full fledged flesh eating animals Solution: Call government agency handling aliens, but say you found it outside so they don’t confiscate your house. #3 I have no idea and would love to know what the heck it is.

I saw one of these a couple years ago coming out of an old, unused radiator on the first floor of an old house in Buckhead. We very cautiously removed it but it grew back!

I’ll bet it’s just some weird offshoot from a tree root. Makes sense, as you said it is “woody” inside. Althogh most roots show a visible taper, I have seen stuff like this when digging up areas some times. So…(fictitious scenario ) It probably got suffocated from all the sewage and came up for air in the basement. ( LOL ) & Lots of luck too.
