Found this fragment in a Niobrara chalk outcropping in southeast SD. Entire rock is about the length of a pen cap, clip included. It has some indentations on the top edge that I think resemble a crinoid imprint, but I'm obviously not sure. Back isn't pictured, but nondescript. Advice would be appreciated!

Could be the impressions of Inoceramus ribs.
