TWO    SHELL  FOSSILS   in  IGNEOUS  ROCK

 

The two rocks beige in color, probably sandstone. They were unearthed in Northern Minnesota.   The larger has the gill imprint from a shell or coral of about 1” in length.    There are also about 3 small round imprints near the shell imprint.   The smaller rock has two imprints from shell, coral, or gills, one about an inch long and the other simply a series of curving lines, about ½”.  The larger rock measures 1-1/2” x 2”; the smaller measures about 1” x 2”.

 

The larger rock has a crack in it and is two-tone, the darker beige being  rougher than the smooth lighter beige areas.    One side of the smaller rock is darker and slightly more rough in texture.

 

These were rocks at the bottom of a prehistoric ocean, showing its marine life ~
