What might there be in Coralville, other than a wedding? There's a surprisingly good set of Devonian fossils downstream from a Corps of Engineers flood control structure. The spillway of their dam allows the fossil beds to be rejuvenated by frequent flooding (recently in 1993, and again in 2008).
We saw some Hexagonaria, and these are other creatures that resemble fossilized bolts.
They look like Crinoid columns - long prehistoric tree-like creatures related to starfish, that you can still find alive in large numbers in parts of the modern-day ocean. Very exciting!
