Monday Geology Picture(s): Fossils in the Floor

Fossils in the floor #1.

My husband and I are travelling in the US at the moment. A little over a week ago we attended an event at the Hynes Convention Center in Boston, and I noticed some interesting fossils in some beautiful building stones on the floor of a hallway connecting the center with an adjacent hotel. I snapped a few pictures of the fossils. Can anyone identify them? Does anyone know where the building stones come from?

Here are a few more pictures:

  1. Believe those are crinoids, often found in limestone. Would not surprise me if the building in Boston was built with Indiana limestone either, which is often full of crinoid fossils.
