Is it dinosaur? This fossil was found in gravel in northwest Iowa and it has not been identified yet. 

That’s what makes events like the
MAPS fossil show a great way to learn and share with other fossil
enthusiasts. MAPS is a non-profit organization of amateurs and
professionals from across the U.S. and several other countries.

Its purpose is to promote popular interest in the subject of
paleontology and to encourage the proper collecting, studying, and
preparation and displaying of fossils. MAPS (Mid-America Paleontology Society) 
has sponsored the National Fossil Exposition since 1979. Corresponding
with their new location in Iowa City, the theme for this year’s show
was “Devonian fossils.” 

Nearby, the Devonian Fossil Gorge in
the Coralville dam emergency spillway offered a unique view of the
fossils that had been exposed there during 1993 and 2008 floods.
