Knippa Tx and going batty figuring out what this rock is.

[Amber]

While out exploring today I found a few points and this rock. It is a perfect egg shape. Smooth to the touch as if it was polished. It has red speckles all around the rim of one side. If it had a dimple in the end I'd say egg/bola stone but it lacks the dimple. It's heavy for it's size and my kids are fascinated with it calling it an egg.

possibly sewed into rawhide and made into a sap, which was then hung from the wrist where it was handy and ready for use.

Probably a concretion. Looks cool though!

Fossilized egg?

 

[stefen]

Take it to a large animal vet clinic and compare it with concretion-like stones removed from horse and cow stomachs...

smooth stones like that were also found at the base of the cliffs which buffalo were run off.It is said that buffalo would for what ever reason swallow stones which would remain in the bellies are worked smooth

 

[stefen]

Most of the stones found in stomach of stock animals are due to ground grazing and/or dirty hay and feed...

Size may range from chicken egg to football size...

Primary reason for horse colic...plugs stomach outlet

I don't remember the proper term but porcelain "eggs" were used to get a hen to "sit" to incubate the eggs. Possibly someone used stone for same purpose? No idea about the speckling. Cool rock.

Without holding it in hand, it almost looks ceramic with a light glaze, which would account for the speckling.

My father worked at a plant that put porcelin on signs and they always had a bunch of porcelain balls like this that they just threw away. My Dad use to put them on the chicken
's roost and keep them on the nest as they thought it was an egg. Monty

In all reality it may be just be a egg shaped rock,I always bring em home to my daughter,she must have a five gallon bucket of em now(she says,they are her dinosaurs)

Yours appears more symmetrical, so may be a naturally polished and rounded rock. Often formed in natural potholes in the river or creek bed.....

However, stones are also commonly crafted into Egg shapes, normally not out of ordinary stone, but out of some type of gemstone.

Ooh! I have a guess! It's a ballast stone:

"In sailing ships, ballast is used to lower the
center of gravity. Ballast often consisted of
rounded stones to avoid abrading the hull
against which they were placed."

Because of shifting and rolling the stones became smooth as if in a large tumbler.

I know you're a little bit from the ocean but I have one that was found about 50 miles from the ocean! Sometimes they were reused for cobblestone streets.
