That is cool! The second photo looks like a tooth, but. After seeing all the photos, maybe bone? How hard is it? Does it appear less yellow/orange in person?

Steel scratches it. It's also semi-translucent. I'm no expert on bone, but I've never seen any with that kind of patterning. I'm still betting on some kind of sea creature with some of the patterning. I just don't know how much detail has been lost through glacial action and polishing. It vaguely resembles a horn coral, maybe? The color is more white overall, but the lines are yellow-brown. Picture is pretty close, maybe a bit dark though.

I'm not a great fossil guy but maybe a partial inner ear bone off a whale or porpoise or some other mammal? Seem to remember finding similar fossil pieces at sharktooth hill back in the day.....Mel

"So why is whale ear bone so dense? Hearing is all about what happens at the interface between a fixed heavy object and lighter objects that vibrate with sound waves. In humans the sound waves travel through air, which is much less dense than our bodies. The vibrations pass via the ear drum through little ear bones to move the liquid in our inner ear. The movement of the liquid relative to the ear bone stimulates the nerve messages to our brain. But whales receive sound through water, which has similar density to their body. The whale vibrates with the water. For a whale to hear, something must vibrate less. It's a little like a seismograph frame that vibrates with the earth movements in an earthquake. The heavy weight suspended within the frame vibrates far less, so the instrument can show the relative movement." Copied from this article nigel-kayak.blogspot.com/2011/05/whale-ears.htmlApparently whales can hear a very long distance, like 1000 miles.
