Dendrites - Plant Pseudofossil?

While at the home and garden supply store picking up concrete materials, this rock was in the landscaping area.  I could not let it get torn up so I saved it from becoming part of a walkway.  Not sure where it came from or exactly what it is. The rock is in layers in a pinkish-red color with dendrite patterns through out.  On one edge is a collection of small crystals.  If the rock could be split it appears more layers have the dendrite pattern.
