My nine year old son loves geology so we spend a lot of time exploring the DFW area for interesting rocks. Today, we came across this in a field in Tarrant County. From a distance it looked like petrified wood because of the organic-looking patterns. Based on the photo provided, can anybody help us identify this stone and explain its unusual features?
